Abstract
Osteochondritis dissecans (OCD) is an idiopathic, focal subchondral bone lesion that is most commonly seen in the knee. It can potentially lead to instability of the lesion, which may affect the patient's or athlete's quality of life and contribute to the progression of osteoarthritis. This report describes a 14-year-old male who presented with left knee pain following a session of soccer. Radiographs and magnetic resonance imaging (MRI) findings were consistent with an OCD lesion of the medial femoral condyle of the left knee. A shared decision was made to pursue conservative management, which included strict cessation of all physical activity and initiation of a home exercise program focused on maintaining range of motion and low-impact strengthening. Surgery was consulted while the patient was being treated conservatively, who recommended surgical intervention, but this was deferred after discussion with the patient and family. With extended conservative management (continued cessation of physical activity) and structured physical therapy (PT), the patient experienced clinical improvement. The patient progressed to weight-bearing exercises under PT supervision and solo soccer drills, with complete resolution of symptoms and no recurrence of pain. The objective of this case report is to highlight extended conservative treatment as a feasible alternative for managing OCD of the knee in patients who decline surgical intervention.
