Fig. 1D. Cadaveric specimen of skeletally mature knee. Posterior
photograph depicts various reinforcements of fibrous capsule and surrounding
structures. Note tendon of biceps femoris muscle (B) superficial relative to
fibular collateral ligament (FC). Fabella (f) is embedded within lateral head
of gastrocnemius (lG), which has been reflected. Fabella (f) is connected via
fabellofibular ligament (fF) to head of fibula. Deep relative to
fabellofibular ligament (fF), lateral (upright) limb of arcuate ligament (uA)
courses upward to reach lateral femoral condyle. Medial (arcuate) limb of
arcuate ligament (aA) borders entrance of popliteus tendon into joint. From
tendon of semimembranosus (S), oblique popliteal ligament (O) crosses
posterior wall of fibrous capsule to reach lateral femoral condyle, where its
fibers merge with those from medial (arcuate) limb of arcuate ligament (aA). P
= popliteus muscle.
