When to Seek Treatment
Your knee relies on four major ligaments to keep it stable.
- The ACL and the posterior cruciate ligament (PCL) are in the center of your knee. The ACL controls rotation and forward movement of the knee joint, while the PCL controls backward movement.
- The medial collateral ligament (MCL) controls stability of the inner (medial) knee while the lateral collateral ligament (LCL) controls stability of the outer (lateral) knee.
When to Make an Appointment
A pop and knee swelling during physical activity need prompt medical attention; there's a good chance you’ve torn your ACL or had a knee ligament injury.
