Range of motion is an important determinant of the success of total knee arthroplasty. This study aims to assess the various demographic factors affecting the postoperative range of motion following total knee arthroplasty which include age, sex, body mass index, etiology, preoperative range of motion, the timing of surgery and the choice of implants These results could be used to identify the patients who are prone for decreased range of motion after total knee arthroplasty. The Materials and methods in this Study was conducted on 254 patients undergoing primary total knee arthroplasty, accounting for a total of 354 knees, with a follow up period ranging from a minimum of 6 months, going upto 2 years. The range of motion was assessed periodically and the recordings were statistically analysed to find a correlation with the above mentioned factors. The Results and conclusion was Age and sex of the patient was not found to affect the postoperative ROM. A poor pre operative ROM, BMI >25 and presence of rheumatoid arthritis were found to result in decreased post operative range of motion. The choice of implant (metal backed or all polies) and the timing of surgery (bilateral single sitting vs staggered) did not appear to be statistically significant in influencing post operative ROM.
