LCL Stretching After Knee Replacement: Recovery Expectations

It is unlikely that a stretched lateral collateral ligament (LCL) will return to normal after knee replacement surgery with time. The LCL is a band of tissue that connects the thigh bone (femur) to the shin bone (tibia) on the outside of the knee. It helps to stabilize the knee joint and prevent it from buckling outward.

During knee replacement surgery, the LCL may be stretched or damaged in order to access the knee joint. This can cause the LCL to become loose and unstable, which can lead to knee pain, instability, and difficulty walking. In some cases, a stretched LCL may require surgical repair to restore stability to the knee joint.

If you are experiencing knee pain, instability, or difficulty walking after knee replacement surgery, it is important to see your doctor to determine if your LCL has been stretched or damaged. Your doctor can recommend the best treatment options to help you recover and regain full function of your knee.
