Abstract Restricted motion of the knee occurs frequently after an intra‐ articular fracture of the distal femur. Treatment of this complication typically requires open release of the quadriceps muscle. To our knowledge an arthroscopically assisted method of performing a quadricepsplasty has not been previously described. We present such a case and the details of the arthroscopically assisted method that may provide an alternative, minimally invasive means of restoring knee flexion in the setting of a post‐traumatic extension contracture.
