Abstract
Objective To explore factors affecting range of motion in patients accepting total knee replacement with highflexion prosthesis.Methods From August 2013 to August 2014, 182 patients accepting total knee replacement with highflexion prosthesis who accorded with our selection criteria were included. The following data were selected by the means of questionnaire: gender, age, body mass index (BMI), diagnosis, patella resurfacing, preoperative ROM, application time of tourniquet,flexion deformity, HSS score and ROM of 12 months after surgery. The data were recorded and analyzed.Results There were 62 males and 120 females in this study with mean age of 63.2 years. The results showed that knee ROM of patients in osteoarthritis (OA) and patella resurfacing group was better than that of patients in rheumatoid arthritis (RA) and patella non-resurfacing group. Secondly, in comparison with patients whose postoperative ROM was less than 125°, lower BMI, greater ROM before surgery, less tourniquet time, less level of deformity and better HSS score were found in patients whose postoperative ROM was greater than 125° (P<0.05). Finally, multivariate analysis showed that RA, non-resurfacing and preoperative ROM<100° were risk factors for postoperative ROM less than 120° (P<0.05).Conclusion The factors related to thefinal ROM for patients who accepted highflexion prosthesis include BMI, preoperative HSS scores, patella resurfacing, preoperative ROM and deformity.关键词
