Clinical results of tibial tubercle osteotomy in primary or revision total knee arthroplasty cases in which it was difficult to evert the patella were evaluated. Causes for difficulty in everting the patella varied with the case, but the same surgical procedure of a lateral periosteal hinged tibial tubercle osteotomy was carried out for each. The length of the osteotomy was approximately 5 cm. After implantation, three titanium wires 1.0 or 1.2 mm in diameter were used for fixation. These procedures were performed in 16 joints of 12 cases which had undergone primary TKA, and 9 joints of 8 cases which had undergone revision TKA. Complications were two cases which showed tibial fracture during the postoperative course. One of these was a traumatic injury due to a vehicle accident. Tibial tubercle osteotomy is a useful method in primary or revision TKA cases in which it is difficult to evert the patella. There was no difference in postoperative physical exercise compared with normal TKA cases.
