简介：
Overview
This study presents a cyclic loading-induced intra-articular cartilage lesion model in the rat knee, achieved through 60 cyclic compressions of 20 N, leading to damage in the femoral condylar cartilage. The method allows for cartilage damage without surgical intervention, making it accessible for operators with varying experience levels.
