The medial collateral ligament (MCL), also called the superficial medial collateral ligament (sMCL) or tibial collateral ligament (TCL), [1] is one of the major ligaments of the knee. It is on the medial (inner) side of the knee joint and occurs in humans and other primates.
The bony congruity of the medial knee consists of the opposing surfaces of the medial femoral condyle and the medial tibial plateau. On the medial femoral condyle there are three bony landmarks that are important: the medial epicondyle, adductor tubercle, and gastrocnemius tubercle. The medial epicondyle is the most distal and anterior prominence.
The initial cut is made in between the posteromedial border of the tibia and medial aspect of the tibial tubercle. Medial collateral ligament (MCL) is exposed by cutting the sartorius fascia and pulling it medially. MCL is then removed from its insertion medially. Two K-wires are placed towards the lateral cortex, about 4 cm below the joint line.
During activities such as overhand baseball pitching, this ligament is subjected to extreme tension, which places the overhand-throwing athlete at risk for injury. [4] Acute or chronic disruption and/or attenuation of the ulnar collateral ligament often result in medial elbow pain, valgus instability, and impaired throwing performance. There ...
The pes anserinus is around 5 cm below the medial tibial joint line. [2] It lies superficial to the tibial insertion of the medial collateral ligament of the knee. [ 1 ]
The MPFL's origin is on the femur between the medial femoral epicondyle and the adductor tubercle, while being superior to the superficial medial collateral ligament. From the origin, it moves anteriorly, and combines with the deep portion of the vastus medialus oblique , inserting to the superomedial side of the patella, creating greater ...
The tendon's name, which literally means "goose's foot," was inspired by the pes anserinus's webbed, footlike structure. The conjoined tendon lies superficial to the tibial insertion of the medial collateral ligament (MCL) of the knee. [citation needed]
The fibular collateral ligament (FCL) connects the femur to the fibula. It attaches on the femur just proximal and posterior to the femoral lateral epicondyle and extends approximately 70 mm down the knee to attach to the fibular head. [10] [11] From 0° to 30° of knee flexion, the FCL is the main structure preventing varus opening of the knee ...
