Evaluation of Patellar Crepitus Following Total Knee Arthroplasty

Status Completed

Clinical Trial Summary

Analyze clinical data for a group of subjects implanted with a new surgical device designed to reduce the incidence of patellar crepitus following PCL-substituting TKA and compare that to a control group of subjects implanted with a TKA design known to have an incidence of patellar crepitus of approximately 5%.

Clinical Trial Description

Patellar crepitus and clunk following posterior cruciate substituting total knee arthroplasty is a persistent problem with a reported incidence as high as 14%. The development of this complication necessitates additional surgery in some patients. Numerous etiologies have been reported including design of the femoral component. Due to a higher than desired incidence of patellar crepitus with the PFC Sigma PS TKA, design modifications of the trochlear groove of the femoral component were introduced with the release of the PFC Sigma HP PS femoral component. The purpose of the proposed study is to evaluate the incidence of patellar crepitus after posterior cruciate substituting TKA utilizing the PFC Sigma vs. the PFC Sigma HP PS femoral components. ;
