Fig. 3From: Quantitative evaluation of very early cartilage damage in experimental osteoarthritis using scanning electron microscopyAssessment of roughness of tibial cartilage. Mice were subjected to a sham procedure or transection of the medial collateral and anterior cruciate ligaments (ACLT) or ACLT followed by transection of the medial meniscus (MNCT). Groups were sacrificed 7 or 14 days post surgery. a Data represent mean ± sem of cartilage roughness (µm) using scanning electron microscope (SEM) images (9/group), compared using Student’s “t” test.
