Description

  • General
    • Forms part of the capsuloligamentous complex of the medial knee
    • 8 to 10 cm ligament in length, is the largest structure found on the medial aspect of the knee
  • Superficial MCL
    • Also known as the tibial collateral ligament
    • Origin: proximally from the posterior aspect of the medial femoral epicondyle
    • Insertion: medial condyle of the tibia 5–7 cm below the joint line near the level Pes Anserinus
    • Function: Primary static stabilizer to valgus stress of the knee
  • Deep portion of the MCL
    • Also known as the mid-third capsular ligament, represents thickening of the medial joint capsule
    • Meniscofemoral (ligaments of Humphrey and Wrisberg) inserts into the medial meniscus
    • Meniscotibial (coronary ligament) ligament originates from the medial meniscus, attaches to the medial tibial plateau
    • Function: major secondary restraint to anterior translation of the tibia, provides minor static stabilization against valgus stress
  • Posterior Oblique Ligament
    • Controversy whether this is a portion of the Semimenbranosus, part of superficial MCL, or a distinct structure
    • Resides on the posterior aspect of the superficial portion of the MCL
    • Provides additional static and dynamic stabilization for the medial aspect of the knee
  • MCL Bursa (Voshell's Bursa)
    • Found between the superficial and deep portions of the medial collateral ligament
    • Anterior margin: adjacent to the anterior border of the superficial portion of the MCL
    • Posterior margin: outlined by the junction of the superficial, deep portions
    • Tibial component and femoral component (70% of cases)[1]
