Results of revision total knee arthroplasties (TKAs) have provided relatively lower success rates than that of primary TKAs. We tried to evaluate the results and related problems of revision TKAs.

27 revision total knee arthroplasties were evaluated clinically and roentgenographically with the American Knee Society Clinical Rating System.

Pain score, range of motion, and knee score of aseptic and septic failures increased postoperatively after revision TKAs. Success rates of revision TKAs were 68.4% (13/19) for aseptic failure and 62.5% (5/8) for septic failure. We observed 9 complications including deep infections, wound dehiscence and superficial infections, fractures, and limitation of motion.

Notable improvements were achieved in most of revision TKAs. However, relatively lower rate of success and higher rate of complications of revision TKAs emphasizes the importance of surgical technique handling significant bone loss, aggressive measure for complicated cases, and rehabilitation.
