It stabilizes internal rotation of the knee through all degrees of flexion but bears the most load when internally rotated in full extension. It also acts as a secondary external rotation stabilizer. [3] [4] [11] The MPFL arises from the fibers of the vastus medialis obliquus muscle and attaches distally to the superior medial aspect of the ...
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. Its primary function is to resist valgus (inward bending) forces on ...
Medial head: popliteal surface of femur; superior to medial condyle: Posterior surface of calcaneus via calcaneal tendon: Tibial nerve (S1, S2) Plantarflexes ankle when knee is extended; raises heel during walking; flexes leg at knee joint Plantaris: Inferior end of lateral supracondylar line of femur; oblique popliteal ligament
The greater part of its lateral surface is covered by the tendon of the biceps femoris; the tendon, however, divides at its insertion into two parts, which are separated by the ligament. [citation needed] Deep to the ligament are the tendon of the popliteus, and the inferior lateral genicular vessels and nerve. [citation needed]
The medial part of the ligament extends superficial to the tendon of popliteus muscle [2]: 138 to attach at the posterior part of the intercondylar area of tibia. [3] [2]: 138 The lateral part forms a separate band that extends to the posterior part of [3] the lateral condyle of femur [3] [2]: 138 alongside the tendon of popliteus muscle.
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 ...
Anterior part of the deltoid muscle [1] Subscapularis [1] Teres major [1] Latissimus dorsi [1] Pectoralis major [1] of thigh/femur at hip [2] Tensor fasciae latae; Gluteus generalis; Anterior fibers of Gluteus meralis; Adductor longus and Adductor brevis; of leg at knee [3] Popliteus; Semimembranosus; Semitendinosus; Sartorius
The oblique popliteal ligament (posterior ligament) is a broad, flat, fibrous ligament on the posterior knee. [1] It is an extension of the tendon of the semimembranosus muscle. [1] [2] It attaches onto the intercondylar fossa and lateral condyle of the femur. [2] It reinforces the posterior central portion of the knee joint capsule. [3]
