The four primary ligaments work in concert to prevent excessive movement and keep the joint aligned during dynamic activities such as running, jumping, and pivoting. 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.

The lateral collateral ligament (LCL) performs the opposite function, stabilizing the outer knee against varus stresses and contributing to overall joint alignment. On the posterior thigh, the hamstring group—comprising the biceps femoris, semitendinosus, and semimembranosus—facilitates knee flexion and works synergistically with the cruciate ligaments to control deceleration during gait and athletic maneuvers.
The medial collateral ligament (MCL) provides resistance against valgus forces, protecting the inner aspect of the knee from impacts or stress. The quadriceps femoris, a four-headed muscle group on the anterior thigh, acts as the primary extensor of the knee, crucial for activities ranging from walking to rising from a seated position.
MCL Knee Injury Prevention Strategies
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. Muscles That Move and Support the Knee Muscles generate the forces necessary for movement, and the muscles surrounding the knee are responsible for flexion, extension, and dynamic stabilization that protects the passive restraints like ligaments.
