📌 Three Types of Medial Patellofemoral Ligament (MPFL) Avulsion Injuries at the Patella
- Generally, MPFL ruptures at the midsubstance or near the patellar attachment are treated non-surgically.
- However, significant patellar MPFL avulsion fractures and femoral attachment MPFL disruptions may pose greater risks.
- Skeletal immaturity can influence the injury pattern, with isolated patellar-based MPFL/chondral injuries being more common in skeletally immature patients.
1️⃣ Type P0:
Ligamentous disruption at the patellar attachment (partial tear of femoral MPFL).
2️⃣ Type P1:
Bony avulsion fracture from the medial margin of the patella (small avulsion fracture of femoral MPFL), may involve a tear of the transverse component (tMPFL).
3️⃣Type P2:
Bony avulsion involving articular cartilage from the medial facet of the patella.
