Description
Summary:Thirty tibial tubercle osteotomies were performed to obtain exposure and facilitate patellar tracking in 29 patients who underwent total knee arthroplasty. The thickness and width of the bone fragment were gradually tapered from proximal to distal. Fixation was obtained with three or four titanium screws. Average follow-up period was 18 months. Twenty-nine of the osteotomies healed primarily. In one patient, postoperative displacement of the tibial tubercle developed requiring additional screw and suture fixation. Extended tibial tubercle osteotomy is a useful technique during difficult total knee arthroplasty. Poor tibial bone stock is a relative contraindication. The authors recommend that a long tapered bone fragment that is 1.5 to 2 cm thick at the level of the tibial tubercle be elevated and fixation achieved with screws.
