Abstract
Thirteen patients with infected total knee arthroplasty treated by 2-stage revision
requiring tibial tubercle osteotomy in both stages for extensile exposure were retrospectively
analyzed. The preoperative mean range of knee motion improved from 60° (range, 30°-90°)
to 94° (range, 70°-120°) at latest follow-up. The Knee Society knee scores and function
scores were 39 and 18 preoperatively and 78 and 67 at latest follow-up, respectively.
Although proximal migration occurred in 3 cases and a partial proximal avulsion fracture
of the osteotomy segment occurred in 1 case after the second-stage reimplantation,
radiographic bony union was observed in all cases. Sequential repeated tibial tubercle
osteotomy can be a useful extensile surgical approach in staged revision for infected
total knee arthroplasty with satisfactory clinical and radiographic outcomes.
