Abstract:
[Objective] To develop a new method of measuring the posterior condylar angle(PCA)interoperatively,and determine the relationships of the PCA to the femoral shaft-transcondylar angle(FSXC)、the tibial plateau-tibial shaft angle(TPTS)and the femoral shaft-tibial shaft angle(FSTS)in southern Chinese people with osteoarthritic knees.[Methods]During July 2007 to March 2008,the PCA was measured directly in 30 osteoarthritic knees undergoing total knee arthroplasty with the PCA Conimeter designed by the author.There were 29 patients including 3 males and 26 females,and the average age was 66.6 years(range,50~78 years),18 left knees and 12 right knees.The radiologic measurements were performed preoperatively on weight-bearing long leg AP radiographs,which included FSXC,TPTS and FSTS.A linear correlation analysis was performed to determine the relationships of PCA to the FSXC,TPTS and FSTS.[Results]The value of the PCA was 5.2??2.6?.The values of the FSXC and TPTS were 8.6??2.9?and 4.1??4.0?,and both had significant linear correlationships with the value of the PCA(P
