Popliteal cyst
Anatomical dissection of the posteromedial knee capsule. The weak area (A) is identified between the two expansions of the semimembranosus muscle (B), the oblique popliteal ligament (C), and the expansion over the sheath of the popliteus muscle (D). The semitendinosus muscle (E) and popliteus muscle (F) are also indicated

Popliteal cyst
Deep dissection of the posteromedial capsule. The two expansions of the semimembranosus muscle have been elevated, exposing the weak area of the capsule between the posterior cruciate ligament (A) and the posterior horn of the medial meniscus (B) that gives entry to the knee joint. The medial femoral condyle is also visible (C)
