📌 Oblique Popliteal Ligament
- The oblique popliteal ligament (OPL) originates medially from the merging of the semimembranosus's lateral expansion and the capsular arm of the popliteus ligament (POL).
- Laterally, it attaches to the fabella, the meniscofemoral portion of the posterolateral joint capsule, and the plantaris muscle.
- The OPL, a lateral extension of the semimembranosus tendon, surrounds the posteromedial joint capsule and is the largest structure in the posterior knee, forming a fascial sheet approximately 5 cm long and 1–1.5 cm wide.
