Abstract
BACKGROUND:Functional recovery after joint arthroplasty is an important indicator to evaluate the effect and prognosis of total knee arthroplasty, and is affected by patients and many kinds of outside factors. OBJECTIVE:To investigate the influencing factors of functional recovery of knee in patients with knee osteoarthritis after total knee arthroplasty. METHODS:Clinical data of 76 osteoarthritis patients undergoing total knee arthroplasty in the Dongying People’s Hospital from August 2007 to August 2013 were retrospectively analyzed. Hospital for Special Surgery knee score, knee pain Visual Analogue Score, range of motion and posterior slop angle of tibial plateau were compared before and 6 months after surgery. Changes in anterior condylar offset were recorded before and after femoral prosthesis arthroplasty. SPSS 21.0 software was used to analyze the influential factors for Hospital for Special Surgery knee scores after arthroplasty. RESULTS AND CONCLUSION:(1) Hospital for Special Surgery knee score, knee pain Visual Analogue Score, and range of motion were significantly higher 6 months after arthroplasty than that before arthroplasty (P<0.05). (2) Pearson correlation analysis demonstrated that preoperative Hospital for Special Surgery knee score, preoperative knee pain Visual Analogue Score, preoperative range of motion, preoperative posterior slop angle of tibial plateau and preoperative and postoperative anterior condylar offset changes were positively correlated with postoperative Hospital for Special Surgery knee score (P<0.05). Body mass index and inversion deformity angle were negatively correlated with postoperative Hospital for Special Surgery knee score (P<0.05). (3) Multiple linear regression analysis showed body mass index was negatively correlated with postoperative Hospital for Special Surgery knee score (P<0.05). Preoperative Hospital for Special Surgery knee score, preoperative knee pain Visual Analogue Score and preoperative posterior slop angle of tibial plateau were positively correlated with postoperative Hospital for Special Surgery knee score (P<0.05). (4) These results indicated that total knee arthroplasty significantly improved knee joint function. Body mass index, preoperative Hospital for Special Surgery knee score, preoperative knee pain Visual Analogue Score, preoperative posterior slop angle of tibial plateau and preoperative and postoperative anterior condylar offset changes were correlated with the recovery of joint function after total knee arthroplasty.关键词
