To analyze the clinical and radiographic results after revision total knee arthroplasty (TKA). MATERIALS AND METHODS: 122 revision total knee arthroplasties (mean follow up: 5 years 8 months) were performed. The causes of the revision TKA were; polyethylene wear in 77 knees, deep infection in 21, aseptic loosening in 17, and others in 7. Clinical findings & radiologic measurements were assessed using the Hospital for Special Surgery knee rating score (HSS score) & Bauer's methods, and by the roentgenographic method of the American Knee Society. RESULTS: After revision TKA, the average range of motion improved from 103degrees to 111degrees, and the average HSS knee score from 69 points to 90 points. A posterior stabilized prosthesis was used in 84cases (77%), medullary stem in 49cases (40%), femoral augmentation in 36 cases (29.5%) and structural allograft in 38 cases (31.1%). After revision TKA; the average femoro-tibial angle was corrected from 2.5degrees in valgus to 6.9degrees in valgus. Complications after revision TKA were; 1 dislocation of the patella, 1 wound disruption and 1 deep infection. CONCLUSION: The causes of revision TKA included polyethylene wear, deep infection and aseptic loosening. After revision TKA, satisfactory results were obtained using a posterior stabilized prosthesis, medullary stem and augmentation, and a structural allograft for large bone defect and soft tissue instability, respectively.
