Osteochondritis Dissecans of the Weight-Bearing Surface of the Medial Femoral Condyle in Adults

Background: Osteochondritis dissecans (OD) is a syndrome that can be characterized as a non-infectious disturbance of enchondral ossification or as a post-traumatic event. OD occurs in the joint cartilage and physis of long bones, as well as in the talus. The medial femoral condyle is the most commonly affected site. OD of the weight-bearing, inferocentral portion of medial femoral condyle is an uncommon, but still challenging issue in knee surgery. Materials and Methods: This study reports one surgeonʹs experience in the treatment of OD of the weight-bearing surface of the medial femoral condyle in adult patients. A total of 29 knees in 28 patients with OD were reviewed as the basis of this study. Four patients were women and 24 men. The mean age was 29.5 years. Patients were observed for an average of 2 years after surgery. Medial joint line tenderness, anterior knee pain, stiffiness and locking were the major complaints in 60% of cases. Arthroscopic excision of loose bodies with or without drilling of the crater and fixation of the lesions with 2 K-wires, with or without bone grafting, was undertaken for the patients. Results: In our study, the clinical outcome was excellent in I l patients, good in 13, fair in four, poor in one. Arthroscopic internal fixation using two smooth K-wires in 12 cases resulted in an excellent knees in 10 cases and good in 2. All patients reported marked improvement and satisfaction with the surgery. Conclusion: Prognosis for knee function is poor when the OD defect involves a large area of weight bearing surface. Arthroscopic treatment is beneficial in all types of OD lesions. For the lesions of similar size, the stage of OD determines the treatment outcome.
