Figure 3

Posteromedial capsular attachment on the superior edge of the tibia. (a) Posterior aspect of the right knee. The semimembranosus (Sm) tendon is continuous with the posterior joint capsule (Cap) and superficial tendinous membrane of the popliteus (Po). (b) After removal of the popliteus, the Cap complex with the Sm is detached from the superior edge of the tibia (white dotted line). (c) After detaching the posterior cruciate ligament (PCL), the posterior horn of the medial meniscus (MM) is detached from the tibia to detach the Cap more medially. The posterior root area (triangle) is continuous with the posterior Cap attachment area. (d) Medial aspect of the knee. After detaching the Cap anteriorly to the Sm attachment (star), its attachment widths were measured at the anterior and posterior edges of the Sm attachment (L1 and L3), and the minimum width was measured superior to the Sm attachment (L2). Lat Lateral, Post Posterior, Sup Superior.
