Abstract:
BACKGROUND:The incidence of patel ar complications is decreasing, however, the necessity of patel ar replacement remains unclear. OBJECTIVE:To investigate the incidence rate of anterior knee pain and postoperative pain score in total knee arthroplasty without the patel ar replacement and to provide a reference for the formulation of clinical operation scheme. METHODS:151 patients with 193 knees receiving total knee arthroplasty were involved in this study. Al the patients were treated with patel ar forming but not resurfacing of the patel a. The Western Ontario and McMaster University (WOMAC) Osteoarthritis Index and America Hospital for Special Surgery (HSS) score were used to evaluate patients before surgery and at 6 and 12 months after surgery. The function of knee joint, the incidence rate of anterior knee pain and visual analogous scale score before and after operation were compared. RESULTS AND CONCLUSION:After 6 and 12 months of total knee arthroplasty, WOMAC osteoarthritis index was significantly lower and HSS score was significantly higher than those before surgery (P<0.05). At 12 months post-operation, the incidence rate of anterior knee pain was 11.3%, which was significantly lower than the preoperative rate (94.5%) (P<0.05). At 12 months post-surgery, visual analogous scale scores were also significantly lower than the preoperative score (P<0.05). Total knee replacement without resurfacing of the patel a can effectively improve knee joint function in knee osteoarthritis or rheumatoid arthritis patients, ameliorate the symptoms of anterior knee pain, has a good clinical effect within short term post-operation. The middle-and long-term effects need further exploration.
