๐ Popliteus Injuries
- Most popliteus tears are extra-articular, involving the muscle or myotendinous portion
- Less common: injuries to the tendon within the popliteal hiatus or near femoral insertion
- Musculotendinous junction or femoral insertion injuries are common in high-grade posterolateral corner (PLC) injuries
- Isolated popliteus injuries represent <10% of cases
โ Imaging Findings Extra-articular tears:
- Muscle or myotendinous portion tears
- Strain/grade II lesion at myotendinous junction (white arrows)
- Extensive circumferential soft tissue edema
- Popliteus tendon appears intact
โ MRI Findings Injury appearance varies by location and severity:
- Abnormal signal in popliteus muscle
- Irregular tendon contour with peritendinous edema
- Tendon avulsion from femoral attachment
