Autologous bone grafting without screw fixation for tibial defects in total knee arthroplasty.
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.
