What are the symptoms of Acl tear?

ACL, or anterior cruciate ligament, is one of the four primary bands of tissues, or ligaments in your knees, that connect the three bones, namely femur (thigh bone), tibia (shin bone) and patella (kneecap), in your joint. The ACL helps you control your knee’s movements in several directions and also stabilises it.  

Athletes playing certain sports may be more at risk for an ACL tear or sprain. These sports may specifically require you to be intensely active while performing a sudden change of direction. These high-intensity sports that may increase the risk of ACL injuries include football, rugby, basketball, etc. Also, you may suffer from an ACL injury due to a sudden and direct impact on your knee. 

So let’s discuss the symptoms of a knee ACL tear and other injuries.

Symptoms Of ACL Ligament Tear

ACL tear is one of the most common knee-related injuries. If you have suffered from an ACL tear in the past, you may be well aware of its signs and symptoms. The most prevalent of the symptoms you have after tearing your ACL: 

  • Pain: ACL tear is one of the injuries resulting in severe pain, one of the prevalent symptoms. 
  • Instability: Your knee will become incredibly unstable and may even buckle (give out) when you try to move or stand. 
  • Popping sound: One of the prevalent symptoms of an ACL tear is the sound of pop during physical activity. 
  • Walking inability: Due to the pain and instability, you may not be able to and don’t even want to put weight on your leg afflicted with an ACL tear. 
  • Swelling: The tear in your ACL will cause you to have swelling in your knee 

You may experience these symptoms and more due to ACL tears. But the extent of these symptoms will depend a lot on the severity of the tear and your pain threshold. 

You may also wonder about the location of pain in an ACL tear. Although some people are lucky enough to get away with mild pain, most with a tear in their ACL may experience a lot of pain, typically around the centre of their knee. 

Partial ACL Tear

There are different types of ACL injuries, and not everyone will suffer from a complete ACL tear. ACL injuries fall under three categories, with Grade 1 ACL injuries being classified as the mildest ones. Then there are grade 2 ACL injuries, including situations where a person’s ACL is either partially torn or has gotten loose or stretched. Finally, grade 3 includes the complete tear in your anterior cruciate ligament. 

People playing intense-activity sports may experience an injury known as a partial ACL tear. It means that the person has either loosened or stretched the ligament or had a tear in one or two ACL-forming bundles. Although not as much as a complete tear, a partial ACL tear will also be quite painful and result in swelling. In this injury, instability in the knee will vary from person to person. 

ACL Strain

The least severe type of ACL injury is an ACL sprain. Your anterior cruciate ligament may suffer a strain due to being stretched beyond the limit. Although it won’t result in a tear, it will still be quite painful. 

Diagnostic Tests For ACL Tear

The first step of diagnosis of any medical condition is a physical test. In this test, your doctor will examine your symptoms and test the range of your knee’s motion. 

Afterwards, the doctor will perform a Lachman test. In this test, you will be asked to lay on your back. Then the doctor will try to move and bend your knee to analyse its movement ability and the extent of the injury. 

Another test for this injury is the anterior drawer test, in which your knee is bent and pressure is applied behind it. If your leg bones move out of their place, it may indicate an ACL injury

Then there are tests like arthroscopy and MRI (magnetic resonance imaging) that will help assess the damage in your knee.
