Core Tip

Core Tip: Arthroscopic debridement is a mature treatment for knee osteoarthritis (KOA). Compared with conservative treatment, arthroscopic debridement can significantly improve the knee resting pain and knee functional status of patients with KOA of Kellgren-Lawrence grades I-III within 2 years after treatment. However, compared with conservative treatment, arthroscopic debridement cannot significantly improve knee pain during walking of patients with KOA of Kellgren-Lawrence grades I-III within 2 years after treatment.
