Abstract:
[Objective]To compare retrospectively the clinical outcome in total knee arthroplasty with and without patellar resurfacing.[Method]From October 1994 to October 2004,125 patients(148 knees)with osteoarthritis were enrolled in the clinical trial of total knee arthroplasty,patients received resurfacing(84 knees)or retention patellar(64 knees).Evaluation was done from preoperatively to final followed-up postoperatively.The patients were scored using American HSS Score for knee and the Feller Score for patalla.The data were analyzed using SPSS software.[Result]In resurfacing patella group,the preoperative and final follow-up HSS scores of patients were(39.6?9.8)and(90.9?8.2)points respectively,scores of patailar were(14.4?6.4)and(25.2?4.8),scores of anterior knee pain were(4.6?3.9)and(10.6?4.1).In nonresurfacing patella group,the preoperative and final follow-up HSS scores of patients were(38.8?9.8)and(90.2?8.9)points respectively,scores of patallar were(14.2?6.2)and(25.1?4.8),scores of anterior knee pain were(4.8?3.8)and(10.3?4.1).There were significant differences in both groups preoperatively and postoperatively in anterior knee pain score,but no significant difference between the two groups in anterior knee pain score.[Conclusion]Whether the patellar replaced or not,the most importance for avoiding anterior knee pain postoperatively is the reasonable selection of patient and correct operation.
