Abstract: Objective To evaluate the short-term effects of total knee arthroplasty ( TKA) , and to detect the causes and prevention of major complications. Methods It was a retrospective study since January 2010 to December 2013. There were 63 patients with 70 knees re-ceived primary TKA. KSS knee scores, HSS knee scores, and range of motion ( ROM) before the operation and during the follow-up were as-sessed and analysed. Results According to the results of follow-up and the X-ray observation, the anteroposterior radiographs showed that the artificial prosthesis were placed well and the joint gap were balanced;the lateral radiographs showed that the artificial joint prosthesis we-rer of appropriate size, good tilt angle, and good package effect. There were two cases developed peroneal nerve palsy and they gradually re-stored in 4 to 6 months after surgery. 5 cases were of poor postoperative ROM (0~60 ± 10)°. Strong analgesic medication-assisted release were conducted in 2 to 3 weeks after surgery. 1 case had patellar pain and resorted by arthroscopic lateral ligament of patellar releasing sur-gery. During the follow-up period, TKA significantly improved HSS and KSS scores compared to preoperative scores. ROM was increased from (78. 3 ± 18. 6)° preoperatively to (109. 2 ± 19. 9)° postoperative (P<0. 01). Conclusion TKA was effective to release knee pain, improve ROM and reduce the incidence of postoperative complications.
