PURPOSE: The purposes of this study were to evaluate the clinical results of performing total knee arthroplasty (TKA) with using the posterior substitution (PS) type Scorpio(R) system and to compare the clinical results of the patellar resurfacing group with those of the patellar non-resurfacing group. MATERIALS AND METHODS: 72 TKAs in 51 patients with minimum 7 years' follow-up were evaluated in terms of flexion contracture, the range of motion, the Hospital for Specific Surgery (HSS) knee score and the radiologic findings. We compared the clinical results of 42 cases in 31 patients with patellar resurfacing with those of 30 cases in 20 patients without patellar resurfacing. RESULTS: Flexion contracture, the range of motion and the HSS knee scores were significantly improved after the TKAs. Radiolucencies were found in 14% of the cases on the anteroposterior views of the tibia and in 11% on the lateral views of the femur. One case of aseptic loosening was observed during the follow-up period. There were no significant differences of clinical results between the patellar resurfacing TYAs and the without patellar resurfacing TKAs. CONCLUSION: We achieved favorable results when performing TKAs with the PS type Scorpio(R) system during mid to long term follow-up. There was no significant difference of clinical results between the patellar resurfacing and non resurfacing groups in our study.
