Internal Fixation of Unstable Osteochondritis Dissecans of the Knee: Long-term Outcomes in Skeletally Immature and Mature Patients.

The long-term results after internal fixation of OCD fragments show high rates of healing and sustainable subjective improvement of knee function and quality of life.

Lateral femoral condylar lesion location is an independent risk factor for failure in skeletally mature and immature patients.
