The posterior cruciate ligament (or PCL) is one of the four major ligaments of the knee. It connects the posterior intercondylar area of the tibia to the medial condyle of the femur. This configuration allows the PCL to resist forces pushing the tibia posteriorly relative to the femur.

Contents

The posterior drawer test is used by doctors to detect injury to the PCL.

The posterior cruciate ligament is a section of the patellar tendon joining medially to the lateral quadriceps femoris.

Surgery to repair the Posterior Cruciate ligament is controversial due to its placement and technical difficulty.[1]
