Arthroscopic partial meniscectomy (APM) is arguably the most frequent knee surgery procedure undertaken in the USA, with between 500 000 and 1 million operations performed annually. Surgical treatment of symptomatic meniscal tears with APM (ie, meniscal shaving/trimming) is considered the standard of care for degenerative tears, which are not usually amenable to meniscal repair (ie, suturing).1 Several randomised trials have called into question the utility of arthroscopic surgery among patients with knee osteoarthritis, culminating with the Meniscal Tear in Osteorthritis Research (MeTeOR) trial, which demonstrated no advantage to APM over physical therapy in patients with meniscal tears and moderate osteoarthritis.2–4 A remaining indication for APM is the treatment of symptomatic meniscal …
