3 New Technologies in Total Knee Replacement

Total Knee Replacement (TKR) is one of the most common surgeries performed to reduce pain and help restore the functionality of a patient with severe arthritis or injury to the knee. Increasing demand for TKRs requires improvements in medical technology to enhance the outcome of surgery. It also aims to decrease recovery time, and improve patient satisfaction rates. 

Three of the innovations of knee arthroplasty are: Patient Specific Instrumentation, custom  Knee Arthroplasty Implants, and Robotic-Assisted Knee Arthroplasty. These are based on modern methods of imaging, manufacturing, and automation in order to personalize the surgical procedure according to anatomy and the special needs of the patient. 

These innovations can be understood by professionals to make decisions that optimize surgical accuracy, implant fit, and overall patient health in total knee replacement procedures.

Patient Specific Instrumentation (PSI)

Patient Specific Instrumentation (PSI) is a major advancement in knee arthroplasty. It personalizes the surgical tools used during Total Knee Replacement (TKR). In this process, it starts with providing high-resolution 3D images of the patient’s knee, which are obtained before surgery, typically from CT or MRI scans. 

These images are used to develop an accurate model of the knee anatomy so that a tailored surgical plan can be developed detailing the bone resections and the positioning and alignment of the implant components.

Once the surgical plan is accepted, the orthopedic surgeon sends orders for the company to manufacture individualized cutting blocks or pin guides based on this patient’s specific anatomy. The guide is shipped pre-sterilized in a bag suitable for introduction into the sterile operating room and applied during the surgery onto the patient’s femur and tibia. 

The guides are designed to be closely contoured against the bone so that precise cuts are carried out as predetermined preoperatively. Surgeons carry out the resections of bone through the PSI guides cutting slots by using standardized surgical saws to ensure optimal alignment and positioning of the implant parts. T

Benefits

This technology has the following benefits: 

  • PSI enables more accurate bone resections and placement of implants based on the patient’s anatomical features.
  • It also enables less invasive surgical techniques due to the possibility of precise guiding, which could reduce the extensive exposure of bones.
  • Preoperative planning could potentially shorten operative time.
  • PSI guides allow for a better fit of the implant with the patient’s bone structure, thus reducing the chance of an overhang or under-coverage of the implant.
  • Intramedullary canal violation may be avoided, thus lowering the chances of fat embolism and blood loss during the surgical procedure.

Customized Implants for Knee Arthroplasty

Personalized Knee Arthroplasty Implants are indeed the new direction to highly individualized solutions in the surgical procedure for knee replacement. These implants come in custom-design shapes and sizes, as against standard implants coming in fixed size and shape, and are unique to each patient’s knee anatomy. 

The process commences with a detailed imaging of the patient’s knee joint taken using modalities such as MRI or CT scans. These images are then utilized to create a precise three-dimensional (3D) model of the patient’s femur and tibia.

The implant is designed to mimic the patient’s knee structures, including the condylar radii, joint-line obliquity, and the configuration of the trochlea and tibial plateau, by using advanced manufacturing techniques such as additive manufacturing, or 3D printing. 

In this process, the engineers are able to collaborate closely with surgeons in the design to ensure the implant not only fits the bone but also meets the unique functional needs of the patient. The blocks are customized, hence the surgeon can have a template so that during surgery, the bone is cut along the same lines as planned preoperatively. 

Advantages

This technology has various benefits, they are as follows: 

  • The implants are designed to fit the patient’s native anatomy of the knee, so the fit and integration with the bone is more optimal.
  • Personalized implants can be used to enable better ligament balancing, reducing the risk of postoperative instability.
  • These implants help in achieving more natural movement and function by replicating the geometry of the native knee.
  • Custom sizing reduces the risks of implant overhang or under-coverage that may potentially lead to soft tissue irritation.
  • A customized approach would result in a higher patient satisfaction rate because of better functional results and comfort.

Robotic-Assisted Knee Arthroplasty

Robotic-Assisted Knee Arthroplasty is one of the frontiers in the field of surgical precision and automation, which helps orthopedic surgeons to better perform Total Knee Replacement (TKR). Computer-assisted technologies are integrated with robotic arms for the assistance in bone preparation, implant positioning, and ligament balancing. These systems can be divided into passive, semi-autonomous, and autonomous, which provide different levels of assistance and control.

It begins with a very detailed surgical plan, either based on preoperative imaging such as CT scans or through intraoperative mapping of the bone surfaces. Image-based systems make use of a preoperative CT scan to produce a 3D model of the patient’s knee; that guides the surgical plan. Image-free systems depend on real-time intraoperative mapping without preoperative imaging. After setting the plan, the robotic arm guides the surgeon in precise cutting of the bone along the predetermined parameters. It avoids taking away bone beyond the planned limits and thereby ensures greater precision in implant placement and positioning.

In the intraoperative stage, the robotic system immediately feeds back the balance of ligaments and position of the implants. Based on this feedback, surgeons can make the necessary adjustments to ensure proper alignment and stability of the knee joint. The robotic assistance uses minimally invasive approaches by reducing the need for extensive manual bone cuts, thereby minimizing soft tissue damage and promoting faster recovery. 

Benefits

This technology has various benefits, they are as follows: 

  • The robotic systems can make highly precise bone cuts and implant placement with minimal chance of malalignment.
  • Real-time tension feedback during surgery helps in balancing the ligaments better, improving knee stability and function.
  • Robotics eliminates human error and ensures that each surgical procedure yields consistent results irrespective of the surgeon.
  • Minimal exposure of bones and manipulation of soft tissues leads to less postoperative pain and faster recovery.
  • The surgical plans are customized to each patient’s anatomy through detailed imaging or intraoperative mapping.
  • Risks of complications, such as infection or loosening of implants is decreased.

Conclusion

Novel technologies in TKR have improved operation precision, implant fit, and patient outcomes. Patient Specific Instrument can help with specific bone excision and implantation. Individualized knee arthroplasty implants are designed to match each patient’s unique anatomy.

Robotic-Assisted Knee Arthroplasty combines automation and accuracy to eliminate human error in ligament balance. Despite all of their benefits, these technologies have certain limitations, such as high pricing, lengthy learning curves, and reliance on sophisticated imaging and manufacturing. As these technologies grow advanced and accessible, they will play a larger part in future knee arthroplasty.

Best Sitting Positions After Knee Replacement Surgery: Tips for Optimal Recovery

Knee replacement surgery, also known as knee arthroplasty, is a life-changing procedure. It is designed to relieve pain and improve function in patients with severe knee problems, such as osteoarthritis or injury.  The surgery is a critical step towards restoring mobility, but postoperative recovery is equally important for the success of the procedure. 

Sitting is an activity most people take for granted. It  becomes a central focus during this recovery phase. Adopting the right sitting positions not only promotes healing but also ensures comfort and prevents complications like stiffness, blood clots, and improper joint alignment.

This article explores the best sitting positions after knee replacement surgery and provides practical tips to ensure an optimal recovery process.

Importance of Proper Sitting Post-Surgery

After knee replacement surgery, the body undergoes significant changes. The newly placed artificial joint needs time to heal and settle into place. Sitting is a common posture that can significantly impact recovery, especially since it can exert pressure on the knee joint. 

Poor sitting positions can cause undue stress on the new joint, leading to pain, swelling, and even long-term complications.

Correct sitting postures reduce strain on the knee, encourage healthy blood circulation, and help maintain flexibility in the joint, which is vital for successful rehabilitation.

Key Guidelines for Sitting After Knee Replacement Surgery

Before diving into specific sitting positions, it is important to understand the general guidelines that apply to sitting after knee replacement surgery:

  • Avoid low seats: Low chairs and couches can put excessive pressure on the knee joint, making it harder to get up and potentially causing harm to the new joint.
  • Use chairs with armrests: Armrests provide support when transitioning from sitting to standing, reducing the stress placed on the knee.
  • Keep the knee at a right angle: Aim for a 90-degree angle at the knee to maintain proper alignment and avoid overstretching the joint.
  • Avoid crossing the legs: Crossing your legs can hinder blood flow and lead to stiffness in the knee. Always keep both feet flat on the ground when sitting.

Best Sitting Positions for Knee Replacement Recovery

  1. Sit in a High Chair with a Firm Seat
    A high, firm chair with a straight back and armrests is ideal for patients recovering from knee replacement surgery. A chair that is too low may strain the knee when standing up or sitting down. A seat that is too soft, like a couch, may allow the hip to sink too low, making it harder to maintain proper knee alignment.
    How to Sit:

    • Sit with your feet flat on the ground.
    • Ensure that your knees are slightly below your hips.
    • Keep your back straight, and use the armrests when transitioning to standing.
  2. Sit with a Footrest or Pillow Under the Foot
    In the initial days following surgery, elevating the operated leg can help reduce swelling and promote blood circulation. Use a footrest, small stool, or pillow to prop up the foot while sitting. Ensure that the knee remains at or slightly above the level of the heart to optimize circulation.
    How to Sit:

    • Sit in a chair with a firm back and armrests.
    • Place your foot on a stool or pillow, ensuring the leg is comfortably elevated but not hyperextended.
    • Avoid keeping the knee fully extended, as slight bending is necessary to maintain joint flexibility.
  3. Use a Recliner with Proper Support
    Recliners can be comfortable post-surgery, but they must be used with caution. A recliner with good lumbar support and a firm seat is recommended. Avoid sinking too deeply into the recliner, as this can lead to poor posture. The reclining position should also support your operated knee and reduce pressure on the joint.
    How to Sit:

    • Ensure that your knee is slightly bent when reclined.
    • Use cushions or pillows to maintain proper alignment between your back and the knee joint.
    • Do not lock your knee in a straight position; gentle flexing is essential to prevent stiffness.
  4. Sit at a Dining Table
    Sitting at a dining table is a practical option when you want to engage in everyday activities like eating or working. Choose a chair that is high enough to keep your knee at a comfortable angle. Dining chairs with cushioned seats and straight backs are preferable.
    How to Sit:

    • Sit with your back straight and feet flat on the ground.
    • Use a cushion if necessary to raise your seating height.
    • Ensure that your knee remains in a relaxed, slightly bent position without overextending or crossing the legs.
  5. Sit on a Bed with Back Support
    Sitting on the bed may be necessary in some cases, especially if you’re recovering at home and need to rest. However, sitting on a bed can be tricky due to its soft surface. Always ensure there is proper back and knee support to avoid strain.
    How to Sit:

    • Use pillows to support your back and knee, ensuring that the knee is slightly bent.
    • Avoid sitting cross-legged, as this can cause stiffness and discomfort.
    • Transition to a standing position carefully to avoid twisting the knee.

Tips for Safe Sitting Transitions

Transitions from sitting to standing and vice versa are often challenging after knee replacement surgery. These transitions must be done carefully to avoid unnecessary stress on the knee.

  • Use Your Arms for Support: Push off with your arms when standing up from a chair. This reduces the load on your knee joint and makes the transition smoother.
  • Engage Your Core: Tightening your core muscles can help stabilize your body as you stand up or sit down. This ensures better balance and less stress on the knee.
  • Move Slowly: Avoid quick or jerky movements when changing positions. Move slowly and deliberately, focusing on maintaining balance and proper alignment.
  • Avoid Twisting the Knee: When standing up, ensure that your knee moves in line with your hips and ankles to avoid twisting or overloading the joint.

Managing Pain and Stiffness While Sitting

Sitting for extended periods can lead to stiffness in the operated knee. To manage this, it is important to incorporate small movements and exercises into your routine.

  • Do Ankle Pumps: While sitting, practice gentle ankle pumps to promote blood circulation and reduce the risk of blood clots.
  • Stand and Walk Frequently: Avoid sitting in the same position for too long. Aim to stand up and walk around every 30 to 45 minutes to prevent stiffness and improve mobility.
  • Use Ice Packs: If swelling occurs after sitting for a while, apply an ice pack to the knee for 10–15 minutes to reduce inflammation and discomfort.

Conclusion

Adopting the right sitting positions is an essential aspect of recovering from knee replacement surgery. Sitting in a high, firm chair, using a recliner with proper support, and elevating the leg can all help ensure a smooth recovery. Proper transitions from sitting to standing and including movement while sitting are crucial for avoiding stiffness and promoting joint flexibility.

By following these guidelines, patients can significantly reduce the risk of complications. They can manage discomfort, and improve their overall recovery experience. Always consult with your healthcare provider or physical therapist for these recommendations to your specific needs and recovery.

Frequently Asked Questions (FAQs)

Why is sitting difficult after a knee replacement?
During the first four weeks following knee replacement surgery, it’s advised to avoid sitting for extended periods. When sitting, the leg bends at the ankle, knee, and hip, which can hinder fluid drainage from the leg, potentially causing swelling around the ankle.

How long should you keep your leg straight after knee replacement surgery?
It typically takes 3 to 6 weeks to fully heal, after which you can return to your usual sleeping positions. However, if a certain position causes discomfort, it’s best to avoid it for a few additional days until you’re completely pain-free.

How long will my knee feel tight after knee replacement?

Knee stiffness is the second most prevalent complaint after a total knee replacement surgery, after pain. It is normal for 2 weeks to 3 months following the procedure. This stiffness diminishes as your knee becomes adjusted to the implants

What to Expect When Recovering from Knee Replacement Surgery

 

Total Knee Replacement is a common orthopedic surgery to replace a worn-out knee with an artificial joint (made of metal and plastic). This surgery, also known as total knee arthroplasty, is performed by orthopedic surgeons, and generally, the success rate is above 90 percent. 

The recovery and rehabilitation can help you return to an active lifestyle. The recovery timeline varies between individuals, and usually, the first 12 weeks are crucial in the faster healing process during the recovery period.

General Knee Replacement Surgical procedure

The Total Knee Replacement surgery is adopted only when other treatment methods, such as physiotherapy and painkiller medications, fail to manage the wear-and-tear pain of the knee. This invasive procedure takes 2 to 3 hours under general anesthesia. 

Below is a brief explanation of the steps involved in Total Knee Replacement Surgery. 

  • The surgeon will make an incision around 6 to 10 inches on your knee area.
  • The kneecap is carefully removed and kept aside. 
  • All the injured and damaged tissues are cut, and the unwanted parts are extracted.
  • The surgeon then attaches the artificial implants (made of metal and plastic). After the procedure, the incisions are stitched, and the patient will be taken to the recovery room.
  • The vitals will be closely monitored in the recovery room after surgery.
  • Once vitals are stable, you will begin preparing for discharge. Medications and physical therapy will be provided to enhance the recovery process.

Step-by-Step Recovery Timeline

The timeline for returning to your regular activities after knee replacement surgery varies from person to person. Here is a general idea of what to expect:

0-2 Weeks- Your hospital stay duration depends on your overall general health. In most cases, patients are discharged within a day or two. You may need a walker or crutches to help with walking. Rehabilitation with physical therapy begins immediately to help you regain mobility. 

This week mostly concentrates on managing the swelling and inflammation after the surgery. Pain and slight discomfort might be reduced by medications and applying an ice pack near the surgery site. You should be fully able to extend your knees from day 1 of surgery. 

2-6 Weeks: You might still depend largely on your walking aid, but there will be more mobility compared to the initial weeks. Continue doing physical therapy, including exercises that help strengthen your knee. 

Sitting for too long during this period can make the knees stiff, so alternate between sitting and walking throughout the day. Post-surgical pain is hardly felt after, and you may not require pain medications. 

2-3 Months: You should see significant improvement in mobility and pain relief. You can start to do light daily activities like driving and light household chores.

3-6 Months: Your knee should continue to get better. Most people can return to work at this point, and you can engage in more physical activities.

6 Months and Beyond: It can take up to a year to fully recover. You should be able to resume most, if not all, of your regular activities without pain.

Tips for speedy recovery after knee replacement surgery

There are plenty of things you can do to help yourself achieve a full recovery. Here are a few tips to help you get back on your feet.

Prioritise rehabilitation and recovery:

Strictly follow the guidance recommended by your physician and physical therapist. Regular gentle exercises and movements are crucial for improving mobility and reducing post-surgery stiffness and swelling. 

Make time for rest: 

Give your body sufficient time to rest and heal. Getting sufficient sleep is essential for both recovery and overall health. Use pillows to elevate your leg; it helps in reducing the swelling during sleep.

Managing Swelling and inflammation: 

Use ice packs to reduce swelling and continue with gentle movements to reduce stiff knees. Consult your physician if there is a persistent inflammation unresponsive to medications.  

Improve your overall health:

Staying hydrated and eating a balanced diet contributes to improved healing outcomes. Proper nutrition supports tissue healing. Maintain a balanced diet rich in protein, vitamins, and minerals. 

Take your prescribed medication: 

Take prescribed pain medications as directed to keep discomfort in check. If you experience any discomfort due to the side effects of the medications, discuss it with your doctor.  

Use walking aids or assistive devices: 

In the initial stages of recovery, walking aids such as crutches or walkers help provide stability and support. You can gradually reduce your dependence on these devices as you regain strength. 

Wear supportive shoes: 

Investing in supportive shoes aids in a quicker recovery after knee replacement surgery. The shoes are designed to provide support and stability as it reduces the risk of slip and falls. Choosing the right footwear minimizes the strain on your knee joint, facilitating a smoother recovery. 

Follow the advice of your medical professional: 

Your surgeon knows what is best for you, and your treatment plans are curated accordingly.  Adhere to their post-operative care guidelines, such as restrictions on weight gain and effective wound care practices to facilitate healing.

Robotic Knee Replacement vs Traditional Knee Replacement

Total knee replacement is a procedure for end-stage osteoarthritis patients or those with severe physical damage. It is done by placing implants in place of the original knees; the age category of the patients now includes younger patients looking for some of the best traditional knee replacements. The procedure is also known as total knee arthroplasty.

What is traditional total replacement surgery?

The old style of knee replacement is practised and still preferred by many surgeons in traditional knee replacement surgery. It depends highly on the surgeon’s expertise and keen vision to get an idea through x-rays. Traditional knee replacement surgery involves making an incision of 10 to 12 inches with surgical machines and tools.

Even though the procedure has been fruitful for many in the past years, it is an invasive procedure with a long recovery period. The traditional knee replacement dryer relies on the surgeons’ skills and their judgement ability through which they do bone section and soft tissue balancing. 

Disadvantages of traditional knee replacement surgery

  • The procedure is invasive and hence needs a longer healing period
  • A good amount of soft tissue and skin has to be stretched and involved during the surgery 
  • Higher chances of wear and tear of the knee components due to improper alignment
  • It depends mainly on the experience of the surgeon, who should be an expert in ensuring the success of the surgery

What is robotic knee replacement?

In robotic knee replacement surgery, the medical procedure prepares a virtual mode of the patient’s knee to prepare a plan before the surgery. With a computer, the doctor would guide the robotic arm, which is programmed and successfully replace the damaged knee tissue. 

There are many robotic knee versus traditional knee replacements where the former is the winner. The major difference between robotic vs traditional knee replacement is that only the damaged portion of the knee is removed, and the other healthy intricate parts and tissues are not affected by the surgery. An implant is placed inside, allowing free movement after the knee has healed. 

Benefits of robotic knee replacement surgery

Getting one of the best robotic knee replacements is a safe and informed decision. There are multiple advantages of robotic knee versus traditional knee replacement. Some of these are:

  • The robotic knee replacement involves using smaller incisions, hence quick recovery and gaining back mobility. 
  • A major robotic vs traditional knee replacement advantage is the higher probability of long-term success of the procedure.
  • It is better for those who want a safe and less invasive procedure. There is also laser damage done to the surrounding tissues. 
  • In traditional versus robotic knee replacement, the accuracy of the implant position does not completely rely on the surgeon. Robotic arms have better accuracy and hence give a more natural feeling post-surgery. 
  • Those who want a more customised and dedicated plan should go with robotic surgery. It is a major advantage of robotic knee versus traditional knee replacement.
  • The chances of complications are much less.
  • The robotic method employs the exact pattern of the patient’s joint movement and reduces the risks of damage to nearby cartilages and tendons. 
  • The procedure is mostly a success on the first attempt, and no cases of correction arise. 

 

Who is an ideal candidate to undergo robotic knee replacement surgery?

If you are suffering from knee pain, you should consider visiting an orthopedician to get a better idea of the cause and available treatment options. The decision of surgery whether you are suitable for the surgery or not depends on several factors such as lifestyle habits, age, diet, the extent of the damaged portion of the knee, etc. 

Those who are suffering from severe osteoarthritis are ideal candidates for the surgery. Those with severe pain and knee stiffness due to which daily activities have become a menace should consider understanding traditional versus robotic knee replacement and choosing the ideal option. It is suggested to the patient only when all forms of physical therapy and medication fail to deliver results.

Knee replacement surgeries have gone up drastically in India

Knee replacement surgery is a medical procedure to remove the original damaged knees and put them in artificial joints. The number of Knee replacement surgeries in India has arisen. It can be attributed to factors like the increased population in the ageing category, better healthcare facilities and higher amount of physical activity. Knee replacement surgery is also known as knee arthroplasty. 

The prime reason for the increase in demand for Knee replacement surgeries is the increase in the number of people in the ageing category. With age, the chances of knee damage due to osteoarthritis increase. It is a degenerative joint disease that causes stiffness and pain and interferes with daily activities. These have made the demand for the best knee replacement surgery in India grow more than ever. With more people in the elderly category, people are looking for the best knee replacement surgeon to regain their normal lifestyle. People are mostly in search of a hospital providing the best surgery with a high success rate and has some of the best doctors in their team. 

Another reason for the higher demand for knee replacement surgeries is the increase in the level of physical activity. Nowadays, people are more concerned about their health, so activities like exercising, cycling, running, and sports are a part of their routine. The continuous pressure on the knees has led to faster wear and tear and, thus, the need to get the best knee replacement surgery in India. It can also be seen in the younger patients who do not want to be restrained by knee damage in their upcoming years of life. Thus, the trend of being physically active and sports in India has opened an avenue for the growing demand for the best knee replacement surgeons.

The accessibility to better medical facilities is also a crucial reason for the increased demand for Knee replacement surgeries. Earlier, knee replacement surgery was a complex and costly procedure accessible to the higher society people only. With the growth of the medical tourism industry and the facilities being provided, people are more concerned about their health and eager to seek treatment to treat their ailments. The increase in the number of some of the best knee replacement surgeons and specialty hospitals has led to higher awareness among the people about their condition and how to treat it without thinking of the financial aspect.

Yet the higher rates of knee replacement surgery are the prime hindrance for many Indians. Many Indians do not have medical insurance or reside in rural areas. Hence, the procedure still needs to be made available to many of India. The government of India is working on the healthcare facilities and accessibility of the patients to ensure the needy get the required treatment. It is through financial assistance and the setting up hospitals for the rural population. Those who need the treatment are getting assisted through government initiatives. These government schemes and associates have helped many patients and eased their financial burden. 

Thus, we can say that despite the constraints, the demand for knee replacement surgeries in India has increased exponentially due to a combination of a variety of reasons, such as a higher number of people in the senior age category, higher levels of sports and physical activities and better services and medical accessibility. Even though the cost of the knee replacement surgery is a reason behind it not being chosen by many, there are several ways by which you can go forward with the surgery and free your life from the pain.

In case you are experiencing knee pain, consult a doctor and discuss the cause of the pain and the procedure for treatment. With the increasing need for knee replacement surgery in the country, doctors and the government are taking initiatives to make it easier for people to get the procedure for those in need. Thus, no need to surf and live a life of pain and suffering; consult your doctor and go forward with one of the best knee replacement surgery to live life on your terms.

What Is Knee Replacement Revision Surgery?

What is knee revision surgery?

 

When the knee replacement surgery stops functioning correctly, a revision knee replacement surgery is performed. This surgical procedure involves the replacement of the old device with a new one.

One should take revision surgery seriously. It is supposed to be more complicated than a primary total knee replacement. Moreover, it involves almost the same risks. It is estimated that many total knee revision surgeries occur within two years of the initial knee replacement. 

What makes revision knee replacement more complicated than initial surgery? 

The initial knee replacement provides a lifespan of around 20 years, but the same is not true for revision knee replacement surgery. The performance gets reduced by accumulated trauma, scar tissue, and mechanical breakdown of components. Moreover, the chances of complications are also high. 

The complications arise as the best knee revision surgeons have to remove the original implant, which grows into the existing bone at a given time. Also, with the removal of the prosthesis, only a little bone remains. 

In some instances, a bone graft is required for a new prosthesis. It involves transplanting a piece of bone from another part of the body or a donor.

Bone graft provides support and leads to new bone growth. The procedure requires additional preoperative planning, specialised tools, and exceptional surgical skill. It takes much more time to perform knee replacement revision surgery than a primary initial knee replacement.

You will find some specific symptoms that indicate the need for knee replacement revision surgery. These include:

  • Reduced stability or function in the knee
  • increased pain or an infection 
  • a bone fracture or implant device failure
  • Pieces of the prosthetic device can break off, and the particles can accumulate around the joint.

 

Reasons for a Revision Knee Replacement 

Short-term revisions: Infection, failed procedure that leads to implant loosening, or a mechanical failure

Infection can start showing itself within days or weeks of surgery. It can also occur many years after surgery. 

Infection after the knee replacement generates severe complications. The bacteria that accumulates around the wound or inside the device is the reason for this Infection. It can also be caused by contaminated instruments or by items in the operating room. However, Infection is rarely caused in the operating room as extreme precautions are taken. Infection buildup fluids, and hence a total or partial knee revision surgery is required.

Unusual swelling, tenderness, or fluid leakage are the signs of Infection, and one should immediately contact the best knee revision surgeons. Your surgeon will examine your knee, which includes X-rays and other imaging tests such as CT or MRI scans. It provides information about bone loss and determines if you are suitable for a knee replacement revision surgery.

An aspiration procedure is performed if fluid buildup around the artificial knee. The fluid is examined in the lab to understand the type of Infection and if other treatment steps are in order.

Long-term revisions: pain, loosening due to wear of mechanical components, stiffness, dislocation

Long-term wear and tear of the implant occur over the years. A well-researched statistics on the long-term knee revision surgery rates for knee replacement showed results of 2 per cent for five or more years in 2004. As of 2011, the revision rate is 6 per cent after five years and 12 per cent after ten years. It has also been found that the rate of total and partial knee revision surgery for all age groups within five years of surgery is about 77 per cent. This rate increases to 10 per cent for patients 65 and older.

The long-term total knee revision rates data varies due to several factors, such as age. The chances for revision are lower for younger people. To reduce future problems, try to maintain weight and not indulge in activities such as running, jumping, and high-impact aerobics that cause stress on the joint. 

The aseptic loosening procedure breaks the bond between the bone and the implant as the body attempts to digest the particles. At this time, the body begins to digest bone, known as osteolysis. This causes weakened bone, fracture, or problems with the original implant.
