Surgical technique. (A) After midline incision the patellar tendon after dissection of the paratenon is shown. (B) Three equal slips are created by two vertical incisions taking care not to damage the distal insertion into the tibial tuberosity. (C) Stay sutures are applied to the two peripheral slips and by down pulling of the central slip the patella is brought into the desired position. (D) After radiological confirmation of the proper patellar position the stay sutures are tightened over the patella. (E) The central slip is double breasted, the three slips are joined together and augmentation by nonabsorbable suture material is done at the patella.
