Osteochondral Allograft Transplantation of the Lateral Femoral Trochlea Secondary to Traumatic Injury: A Case Report

A 23-year-old female presented with traumatic loss of the left lateral femoral trochlea and painful patellofemoral instability. She underwent osteochondral allograft transplantation of her left lateral femoral trochlea. After one week, she was able to stand on her left leg, and at six months, she had good patellofemoral stability, was ambulating, and could complete all daily activities as needed. We present this novel case of patellofemoral instability due to traumatic loss of the lateral femoral trochlea treated with a lateral femoral trochlea osteochondral allograft. Our surgical intervention resolved the patient's instability, improved her pain, and preserved function in this case.
