📌Osteochondral Defect at the Medial Margin of the Patella
- Osteochondral injuries associated with transient lateral patellar dislocation typically present with well-defined, full-thickness, or large partial-thickness defects with acutely angled margins.
- It is crucial to search for loose chondral or osteochondral fragments within the joint to prevent further complications.
✅ Displaced Osteochondral Fragment within the Lateral Recess
- A slab of articular cartilage and a sliver of the subchondral bone plate can be observed.
- There is a large displaced osteochondral fragment at the lateral aspect of the lateral femoral condyle and a bone bruise at the anterolateral aspect of the lateral femoral condyle.
Significance of the Radiologist's Diagnosis
- The radiologist’s diagnosis is crucial because if the lesions are larger than about one square centimeter, prompt surgery is indicated.
- Ideally, surgery should be performed within one week of the event.
✅ Osteochondral Defect of the Lateral Edge of the Condyle
- This case shows an osteochondral defect at the lateral edge of the condyle, requiring careful evaluation for appropriate surgical intervention.
✅ Complete Tear of the Patellar Side of the Medial Patellofemoral Ligament (MPFL)
- A complete tear of the MPFL at the patellar attachment is observed, a significant injury given the MPFL's role in stabilizing the patella.
✅Surgical Intervention
- The surgical procedure involved internal fixation using a headless compression screw through the fragment, ensuring stable fixation and promoting proper healing.
