Abstract:
PURPOSE: Bone defects in revision TKA were classified according to AORI (Anderson Orthopedic Research Institute) system and results of the treatment are reported according to this classification. MATERIALS AND METHODS: The results of 24 revision TKAs operated from Mar. 1991 to Apr. 1999 were analysed. Fourteen knees had type 1 tibial defects, four knees had type 2 and six knees had type 3. On the femoral side, twelve knees had type 1, four knees had type 2 and seven knees had type 3 defects. Cement and chip bone grafts were mainly used to fill bone defects in type 1, wedges or blocks in type 2 and structural allograft combined with the other methods in type 3. Results were evaluated using the knee and functional scores of the American knee society. RESULTS: The analysis of the results according to the method of treatment- cement filling, chip bone graft, structural bone graft, wedge or blocks and custom made prosthesis- revealed improvements of knee scores in all groups except for custom made prosthesis. CONCLUSION: Satisfactory clinical results were obtained for the management of bone defects according to the AORI classification system in revision total knee arthroplasty.
