Abstract: Total knee arthroplasties are done commonly, and the overall results are excellent, with 95% of the implants surviving for at least fifteen years1,2. The 5% that fail represent a substantial number, and orthopaedic surgeons are seeing an increasing number of patients who initially had a successful total knee replacement but then had pain, radiographic evidence of failure, and/or dysfunction due to failure of the arthroplasty. Extensive bone loss, instability, infection, dysfunction of the extensor mechanism, and periarticular arthrofibrosis are frequent challenges encountered during revision surgery. A systematic approach to the evaluation of patients requiring revision total knee arthroplasty can help identify the correct diagnosis and guide the surgical intervention, thereby optimizing success.
