Table 1 WORMS features and regional subdivision of the knee joint. Features marked with * were evaluated in the different regions. Cartilage, bone attrition and osteophytes were not evaluated in the S-region

From: Tendon regeneration and muscle hypotrophy after isolated Gracilis tendon harvesting - a pilot study
