Abstract

PURPOSE: The aim of this study is to report the usability of autogenous bone graft with bone peg in total knee arthroplasty in the patients with tibial medial bone defect from osteoarthritis due to severe varus deformity.
MATERIALS AND METHODS
From July 1998 to December 2000, fifteen total knee arthroplasties with autogenous bone graft were performed for the medial tibial bone defects. The proximal tibia was resected and then bone pegs which were prepared from resected portion of distal femur and proximal tibia were inserted into the defect site with the shape of peg in the anterior posterior view using press fitting method. Instead of applying screw or K-wire, we performed press-fitting method for early stability. For attaining the stability, we preserved the sclerotic rim and designed precisely the bony defect site. We reviewed the result using the HSS Knee Rating Scale and observed the radiologic change.
RESULTS
In HSS Knee Rating Scale review, 52.4 of preoperative score was improved to 84.7 at postoperative 1 year. Tibio-femoral angle , the average 17.8 degrees of varus was improved to the average 5.8 degrees of valgus at 1 year postoperatively. The average union period was 5 months, and there was no evidence of the displacement of grafted bone and loosening of the inserted implants.
CONCLUSION
The method of autogenous bone graft applied with bone peg could be supposed as the stable fixation method without using screws or K-wires.
