Posterior condylar cartilage thickness determines accuracy of femoral component rotation during total knee arthroplasty in valgus knees: Comparison with varus knees.

ABSTRACT:

Purpose

Accurate femoral component (FC) rotation is critical in total knee arthroplasty (TKA). Residual posterior condylar cartilage is difficult to assess intraoperatively and may bias the posterior condylar axis. Quantitative data remain scarce, particularly for lateral compartment osteoarthritis, and the assumption of a uniform 2-mm cartilage thickness has rarely been tested.

Methods

Twenty-five valgus knees in 22 Asian women undergoing primary TKA were analysed; 31 previously measured female varus knees, assessed with the same protocol, served as controls. After posterior femoral resection, resected condyles were radiographed perpendicular to the cut. Medial (m) and lateral (l) cartilage thicknesses were measured with magnification adjustment.
