We estimated the risk of incident cartilage defects developing in tibiofemoral compartments with prevalent partial\u2010thickness and full\u2010thickness cartilage defects in only one subregion within the compartment, using tibiofemoral compartments with no baseline cartilage defects as a referent. Logistic regression with generalized estimating equations was used for all analyses, with adjustments for confounders.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 374 compartments (359 knees) were included, and 140 knees (39%) had radiographic OA.
