Abstract

PURPOSE
The aim of this study is to report the midterm results of cementless primary total knee arthroplasty using bone grafting for severe medial defect of the proximal tibia.
MATERIALS AND METHODS
From March 1989 to March 1994, eighteen cementless primary total knee arthroplasty were performed using autogenous bone grafting for severe medial defects of the proximal tibia and were followed for an average of 6 years (range, 5 to 8.3 years) . The rim around the tibial defect was preserved as much as possible.
RESULTS
The mean Hospital for Special Surgery rating score was 57.5 preoperatively and was 83.7 at 5 years postoperatively. Union of the tibial bone grafts has occurred in 15 of 18 knees. Three knees demonstrated evidence of partial graft dissolution. Tibial angle (angle and angle) did not change significantly at the last follow-up evaluation. None of these implants showed subsidence, or loosening. There were 3 revisions due to polyethylene wear, metallosis, and osteolysis regardless of the graft.
CONCLUSION
The bone grafting with limited resection of residual host bone may prove useful in the reconstruction of tibial bone defects as well as in the stability of tibial component.
