📌Anatomy of the Posterior Oblique Ligament
✅ Origin Originates distal and posterior to adductor tubercle (separate from superficial MCL origin)
✅ Proximal Course Identified posterior to superficial MCL proximally on axial imaging
✅ Distal Attachments Three arms:
- Capsular arm - blends with posterior capsule and semimembranosus sheath
- Tibial arm - attaches to posteromedial tibia and meniscus, merges with semimembranosus tendon
- Superficial arm - blends with superficial MCL and semimembranosus insertion
✅ Function: Provides important posteromedial knee stability
