The popliteus muscle, located deep at the back of the knee, initiates flexion and internal rotation of the tibia, unlocking the joint from full extension. The anterior cruciate ligament (ACL) resists anterior translation of the tibia relative to the femur and prevents hyperextension, playing a critical role in rotational stability during cutting and twisting motions.

Conversely, the PCL, which is the stronger of the two, arises from the anterior intercondylar region and inserts on the posterior tibia, preventing the tibia from moving too far backward under load. Key Ligaments: The Primary Stabilizers Ligaments are dense bands of fibrous connective tissue that connect bone to bone, and within the knee, they form the foundational framework for joint integrity.
Common Injuries and Their Anatomical Basis. The posterior cruciate ligament (PCL) prevents posterior displacement of the tibia and is particularly engaged during activities like descending a slope or decelerating from a run.

The ACL originates from the posterior aspect of the medial femoral condyle and inserts on the anterior intercondylar area of the tibia, limiting anterior tibial slide and rotational instability. The medial collateral ligament (MCL) provides resistance against valgus forces, protecting the inner aspect of the knee from impacts or stress.
