Osteochondritis dissecans of the bilateral trochlea of femur is unusual case for orthopedic surgeon. The patient was a healthy 15-year-old male with symptomatic osteochondritis dissecans of the bilateral distal lateral femoral condyle of the trochlea. A surgery on the bilateral knee joints was performed simultaneously. The osteochondral free fragment of the right knee was resected by a minimum open surgery after arthroscopic evaluation. In the left knee the fragment was stabilized with multiple cortical bone pegs harvested from the proximal tibia. The surgery was successful, and the patient was able to play basketball 3 months postoperatively. The course of the right knee is currently under careful observation because of the possibility of recurrence. The left knee has remained in an excellent condition for 18 months following surgery with bone pegs.
