28-year-old male with pain tightness and limited extension
28-year-old male with pain tightness and limited extension with some swelling since fall and twisting injury 3 weeks ago.
Long- and short-axis fat- and water-weighted images were performed on a 0.95-Tesla.
- Extensor tendons are intact
- Moderate-sized hemarthrosis
- High-grade tear of the proximal anterior cruciate ligament
- Diffuse prepatellar and pretibial contusion versus closed degloving injury (Morel-Lavallee syndrome)
- Minimally depressed comminuted posteromedial tibial plateau fracture with 3mm of depression. Extensive nondisplaced fracture in the posterolateral tibial plateau
- Tibiofibular capsular sprain. Likely sprain of the arcuate ligament
- Grade 2 sprain with interstitial PCL tear
- Contusion in the posterior root of the lateral meniscus. No traumatic meniscal tears are demonstrated
- Grade 1 to 2 sprain of the tibial collateral ligament. Lateral collateral complex low-grade sprain noted. Popliteus myotendinous junction sprain. Tendon is intact
- Popliteal neurovascular structures are unremarkable. Chondral contusion demonstrated in the lateral femoral condyle
- Low-grade patellofemoral chondromalacia
- Tiny peripheral vertical meniscus red red zone body microtear. Possible knee subluxation.
- Pivot-shift injury with high-grade ACL tear nondisplaced fracture of the posterolateral tibial plateau grade 2 tibial collateral ligament sprain chondral contusion laterally and contusion of the posterior root of the lateral meniscus without traumatic tear. Interstitial PCL tear. Diffuse capsular sprain.
- Contrecoup injury with mildly depressed fracture of the posteromedial tibial plateau and low-grade fibular collateral sprain.
- Grade 2 sprain with partial tear of the posterior cruciate ligament.
- Posterolateral corner injury with popliteus myotendinous junction sprain (tendon otherwise intact). Tibiofibular capsular and likely arcuate ligament sprain.
- Diffuse swelling in the anterior superficial soft tissues as described.
- Tiny peripheral vertical meniscus red red zone body microtear. Possible knee subluxation?
