title: Autologous bone grafting without screw fixation for tibial defects in total knee arthroplasty.
abstract: We evaluated 30 knees with autologous bone grafts, performed without screw fixation, for tibial defects in total knee arthroplasty (TKA). The tibial defects were classified into three types: contained, flat peripheral, and slant peripheral. The resected femoral condyle was fixed with a combination of bone cement and the tibial component, without using screws. The patients were followed for an average of 6 years and 10 months. In all knees except 1, the grafted bone united and formed good continuity with the tibial floor. Autologous bone grafting without screw fixation is a simple and effective method to deal with the tibial defects in primary TKA, especially for contained and flat peripheral defects.
