Anterior cruciate ligament insertion after partial tear: histological changes and chondrocyte turnover

Purpose The purpose of this study was to clarify the effects of partial resection on the glycosaminoglycan (GAG) layer thicknesses and chondrocyte turnover (apoptosis and cell proliferation) between uncalcified fibrocartilage (UF) and calcified fibrocartilage (CF) layers in an anterior cruciate ligament (ACL) insertion.
