What is a Knee Extension Lag?

Have you been taking for granted the fact that you can move and straighten your knee without experiencing any pain or discomfort? You can experience knee extension lag either after undergoing knee surgery, which makes it uncomfortable to straighten and move their knees.

There are so many things that you can’t do when you are experiencing extension lag in your knees, and this can be a frustrating experience, more so if you have been an active person for a significant part of your life.

So read on to understand what happens when you can’t move your knee, causes and how you can treat or prevent this issue.

What Happens When You Can’t Move Your Knee

If you are experiencing difficulties and pain when you try to bend or straighten your knee, you may be experiencing extension lag, and it is measured in degrees. So the doctors describe the degree to which you can straighten your knee.

For a healthy person, when you stand up, the hamstrings and the quadriceps muscles shut off, and thus, you use very little energy to stand. However, when you are experiencing an extension lag when you try to stand, your hamstrings are shortened, and the quadriceps are still working, so you cannot stand straight.

When your quadriceps and hamstrings do this for years, your tendons and muscles start to tear, and eventually, they will be torn fully; thus, your back knee cap will lose cartilage.

Causes of Knee Lag extension

A knee extension lag is both uncomfortable and painful, and it limits your mobility because you cannot straighten your knees. Thus, it is crucial to understand why it happens to change the causative habits and seek help from a physiotherapy expert like Barefoot Physiotherapy.

Here are the most common causes of knee lag extension:

  • Bone spurs
  • When your meniscus tissue is torn or locking unnecessarily
  • Scarred posterior cruciate ligament or if it is too tight
  • Tight meniscus, muscles
  • After orthopedic knee surgery

Knee extension lag worsens as time goes on because your quadriceps and hamstrings are working to support your body at an unnatural angle. Therefore if you notice any of the symptoms below, you should reach out to your doctor or physiotherapist to recommend an effective treatment plan.

  • Instability in your knee
  • Pain that is localized in the knee joint
  • Swelling and bruising
  • Decreased mobility
