Medial Collateral Ligament of the Knee 🦵

👉The MCL spans the medial joint line and is comprised of two components termed the superficial medial collateral ligament (sMCL) and the deep medial collateral ligament (dMCL).

👉The sMCL is the largest structure of the medial knee (10–12 cm) and functions as the primary stabilizer of the knee against tibial external rotation and valgus stress (https://pubmed.ncbi.nlm.nih.gov/32277264/).

👉 The dMCL, comprised of the meniscofemoral and meniscotibial ligaments, is located deep and roughly parallel to the anterior border of the sMCL and serves as a secondary stabilizer against valgus deformity (https://pubmed.ncbi.nlm.nih.gov/19609008/; https://pubmed.ncbi.nlm.nih.gov/17768198/). These two ligaments, in addition to the posterior oblique ligament (POL), have been identified as the three main static stabilizers of the medial knee (https://pubmed.ncbi.nlm.nih.gov/19609008/).
