Isolated Polyethylene Insert Exchange for Flexion Instability After Primary Total Knee Arthroplasty Demonstrated Excellent Results in Properly Selected Patients

摘要

Background: Historically, isolated polyethylene exchange (IPE) for flexion instability after total knee arthroplasty (TKA) has demonstrated generally poor and unpredictable results. The purpose of this study is to evaluate the results of a single surgeon's strict indications and protocol for IPE for flexion instability after primary TKA.
