Abstract:
PURPOSE: To evaluate clinical results of posterior cruciate retaining TKA according to the preoperative range of motion (ROM), degree of deformity and obesity. MATERIALS AND METHODS: 81 cases were followed up more than 3 years. All cases were evaluated according to degree of preoperative ROM and varus deformity, presence of flexion contracture and BMI scale for obesity. Clinical and radiological evaluation systems were used with American knee society scale. RESULTS: Postoperative ROM according to the degree of preoperative ROM showed that the postoperative ROM in the good preoperative ROM group was better compared to the worse preoperative ROM groups and the results of knee scores showed the similar condition. Flex-ion contracture group revealed the better clinical results (p>0.05) compared to the group without contracture. The improvement of knee and functional scores was statistically significant in the more deformed varus groups and in the normal BMI group compared to the more obese groups. CONCLUSION: Good clinical results and satisfactory postoperative ROM are obtained by the good preoperative ROM, appropriate technique of maintaining adequate soft tissue balance in the deformed knee and preoperative weight control.
