Partial Knee Replacement

Home - Partial Knee Replacement


Our knee joint is made up of three separate compartments, including

  1. The medial (inside part of the knee),
  2. The lateral (the outer part of the knee) and
  3. The patellofemoral (front part of the knee).

If for any reason, only one part of those three compartments gets damaged, and if the health condition is not reversible with significant medical treatment, you are absolutely appropriate to opt for Robotic partial knee replacement.


Robotic Partial Knee replacement is a surgical method to reverse or relieve the pain to your knees caused by the wear and tear of the cartilage. This is called robotic as the procedure is done using a robotic arm. In this procedure, the surgeon needs to treat only the affected area, and the treatment is best suited for adults who are suffering from osteoarthritis.

The procedure is called partial, as in this process, the surgeon doesn’t replace the entire knee. Only the affected part gets replaced while leaving the rest of the joint alone.


Evaluation: We have the best knee replacement surgeon in Hyderabad, and thus our patients can be confident about one fact, that they are suggested with the best possible treatment procedure. We don’t jump into treating the condition with our tools.

Before suggesting partial knee replacement to a patient, our expert team prefers to review each symptom of the patient. The background knee history and another medical history of the same patient gets evaluated thoroughly. It helps our team to understand the situation of the patient.

X-Ray and 3D CT Scan Evaluation: The robotic partial knee replacement procedure includes X-Ray and 3D CT Scan, which allow the surgeon to create a virtual model of the current state of the patient’s knee and make a further pre-operative plan.

The surgeon can guide the robotic arm in resurfacing the damaged knee part through computer assistance.

MRI provides the best study of the patient’s current condition. Condition of the bones, ligaments and the cartilage can be evaluated thoroughly for an error-free surgery.

Pre-Operative Plans:

  • The medical history and the current health condition of the patient, allows the surgeons to opt for a partial knee replacement
  • The accurate 3D knee imaging data is loaded into our advanced software program, as the process of the pre-planning.
  • It helps the surgeons to determine the precise size, the depth of the implant, Coronal Rotation and plane alignment, and other procedures to result in an appropriate surgery.

Partial Knee replacement is comparatively a complicated surgery process, and the pre-planning of the surgery makes a big difference in the effectiveness and quality of the operation.

The preoperative anatomic plan of the surgery gets optimized during the surgery from gap analysis, mapping of the cartilage surface and motion data.

Advantages of PKR:

There are many advantages to go for a partial knee replacement, rather than a total knee replacement. Partial knee replacement has certain benefits like:

  • The incision size required for the replacement is of 2” to 3” and no muscles are cut during the operation thus the patients get relieved soon from their health condition and come to back to their own ability within 2 hours.
  • There is minimal pain after the surgery and also lesser blood loss during the procedure, and the healing process can be speeded up with the help of platelet-rich plasma too.
  • For the closure skin adhesives are enough after the surgery; thus, the patients don’t need to come for removing any staple after the surgery.
  • Partial knee replacement surgery is highly accurate than other open surgery processes. It helps the patients to get back to their healthy life within a week.

The operation:

The advanced tools and machinery used in Germanten help our surgeons to craft and trim the remained bone edges and tissues so that they can get healed quickly.

We use advanced medicines during and after the partial knee replacement surgery. Electro Cautery knives are used which minimizes the bleeding during the surgical process.

  • Temporary infrared tracking devices or “Arrays” are placed on the tibia and femur during the operation. These allow the surgeons to see the movement of the bones and also to know the position of the robot with the cutting tool.
  • It helps in obtaining the precise location of the affected area. Once the communication is set, the overgrown bone spurs can be removed.
  • The surgeons prefer to bend the knee during the operation to optimize the angular alignment and re-tensioning the ligaments.
  • The computer software presents the tracking information, and other details to the surgeons so that the virtual adjustment of the implant can be made.
  • A 6mm cutting round tool is connected to the robotic arm across the bone edge, and it removes the desired portion of the bone.
  • The robotic arm limits the area of resection to only the planned area, and the system creates a virtual boundary to limit the movement of the cutting tool.
  • Once the bone surface of the knee gets prepared by the robotic arm and the cutting tool, the soft tissues of the joints get trimmed and ready for the installation of the implant.
  • Several trial implants are done before opting for the final implantation.

The definitive implantation is done with the help of bone cement, attaching the implant to the tibial and femoral bones.


  • We have a team of expert knee replacement surgeons in Hyderabad, who are operating the same medical problem since long.
  • We have a wonderful team of experienced surgeons and doctors for robotic partial knee replacement, which is led by Dr Mir Jawad Zar Khan who is known for his expertise in orthopedic surgeries and consultation. He has a vast experience of 20 years in this field.
  • The pre-operative evaluation and planning are what decides the success rate of PKR surgery. We take immense pride in taking most of our time in the segment.
  • In many cases, the pre-operative tests reveal other health conditions which influence the decision of the surgeon for the betterment of the patient.
  • We are focused on optimizing the wound healing in all of our patients. Thus, Germanten is considered to provide the best knee replacement surgery in India.

We take care of the entire process, including the pre-operative, operative and post-operative recommendations which enhance the wound healing and recovery of the patient.


At Germanten, we provide an immediate post-operative partial knee replacement surgery recovery recommendation to our patients. The patients who undergo surgery are relieved once they are awake, medically stable and get a chance to walk with their assistive devices. We also arrange further required accommodation if the patient needs to stay for longer.

A cooling knee sleeve device is recommended after the patient goes back home post-surgery. The patients are advised to walk for shorter distance with support and then without support. At Germanten, we make sure that you get back to your flexible self within the shortest time possible.
