Medial Patellofemoral Ligament
- aka 'MPFL'
- Anatomic description
- Ligamentous anchor between the patella and femur
- Femoral attachments: 1.9 mm anterior, 3.8 mm distal to the adductor tubercle and 10.6 mm proximal and 8.8 mm posterior to the medial epicondyle
- Patellar attachments: broad insertion onto the medial superior half of the patella (deep to the Vastus Medialis Obliquus
- Prevents excessive lateral movement of the patella
- Most important patellar stabilizer during the first 30° of knee flexion
- Provides 50%–60% of medial restraint to lateral subluxation
- Trochlear groove providing further patellar stability with deeper knee flexion
