Association Between Femoral Component Sagittal Positioning and Anterior Knee Pain in Total Knee Arthroplasty A 10-Year Case-Control Follow-up Study of a Cruciate-Retaining Single-Radius Design

摘要

Background: Anterior knee pain is the most common complication of total knee arthroplasty (TKA). The purpose of this study was to assess whether sagittal femoral component position is an independent predictor of anterior knee pain after cruciate-retaining single-radius TKA without routine patellar resurfacing.
