Femoral Component Loosening is the Predominant Mode of Early Failure in Contemporary Cementless Total Knee Arthroplasty.

ABSTRACT:

Background

Cementless total knee arthroplasty (TKA) has seen a resurgence due to advancements in tibial implant fixation. However, most femoral components remained unchanged, typically being cobalt chromium with nonenhanced porous ingrowth surfaces. The literature is sparse concerning radiographic and clinical outcomes related to the femoral component in uncemented designs.

Methods

This retrospective, single-center study included 268 cementless TKA. Radiolucent lines were evaluated using the Knee Society Radiographic Evaluation and Scoring System. Clinical outcomes were measured using the Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS JR). Linear regression modeling was performed to analyze the relationship between KOOS JR and the presence of radiol
