الملخص EN

Osteochondral fractures of lateral femoral condyle are common in adolescents and young adults.

They are usually caused by direct trauma or twisting injuries of the knee.

We present a case of large osteochondral fracture of lateral femoral condyle involving the articular surface in a fifteen-year-old male with a positive history of significant weight gain of 5 kilograms in last six months.

Blood investigations reported low vitamin D and testosterone levels with elevated alkaline phosphatase.

Adequate exposure was achieved by doing Z-plasty of quadriceps apparatus.

The fracture was treated with open reduction and internal fixation using Herbert's screws.

Medical management in the form of vitamin D and calcium along with testosterone was given.

After the surgery, full weight-bearing was allowed at three months.

At one year followup, patient has good quadriceps function without any weakness of the muscle.
