Oblique Popliteal Ligament

Description: - passes from insertion of the semimembranous on posteromedial aspect of tibia obliquely & laterally upward to insertion of semimembranosus on the posteromedial aspect of the tibia obliquely & laterally upward toward insertion of the lateral gastroc head;
- it acts as important stabilizing structure on posterior aspect of knee;
- semimembranous helps tighten this structure with contraction;
- when the oblique popliteal ligament is pulled medially and forward, tightens the posterior capsule of the knee;
- this maneuver can be used to tighten the posterior capsule in the posteromedial corner of the knee in surgical repair;
