Validation of Articular Cartilage Depth in Total Knee Arthroplasty.

ABSTRACT:

Background

Understanding cartilage thickness is critical for execution of an unrestricted, calipered kinematic total knee arthroplasty (TKA). Historically, condylar cartilage was assumed to be 2 mm thick. However, thickness may vary based on age, sex, body mass index, anterior cruciate ligament (ACL) status, and alignment. This study aimed to determine in vivo cartilage thickness in patients undergoing TKA and evaluate which factors affect variation. Our hypothesis was in vivo cartilage thickness would be 2 mm on average, but some patients would have greater than 2 mm based on demographic factors.

Methods

This multicenter, prospective cross-sectional cohort study evaluated condyle cartilage thickness from resected fragments. Univariate statistics and general linear models we
