High Rates of Aseptic Loosening in Modern Posterior-stabilized Femoral Components From a Single Manufacturer

ABSTRACT:

Background

Total knee arthroplasty (TKA) is one of the most commonly performed surgical procedures in the United States. There are concerns and reports of early aseptic loosening due to debonding at the cement-implant interface in a specific posterior-stabilized femoral design. This study describes failure at the cement-implant interface with 2 femoral implant designs produced by a single manufacturer.

Methods

This is a review of failed primary total knee arthroplasties performed with Optetrak Logic and Truliant posterior-stabilized femoral components between 2010 and 2020. Cases with revision surgery performed for femoral component loosening were reviewed.

Results

Seventeen of 896 knees were revised for femoral component loosening. The mean time from index arthr
