The primary treatment typically involves non-operative methods; however, in cases of persistent symptoms, operative intervention has been proposed as a viable option. Depending on the tear\u2019s morphology, treatment may involve debridement (central or radial tear) or repair (peripheral tear). Efficacy of operative treatment has not been studied in a randomised controlled trial.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>This is a prospective, randomised, controlled, blinded multicentre trial, with two randomisation stratums. The first stratum includes central or radial TFCC tears, while the second stratum comprises peripheral TFCC tears. Each stratum consists of two parallel 1:1 arms, comparing the efficacy of (1) debridement of central or radial tear with placebo surgery and (2) repair of peripheral tear with physiotherapy. Participants are recruited from secondary and tertiary referral hospitals in Denmark, Finland and Sweden.<\/jats:p>\n                    <jats:p>Primary outcome is the Patient-Rated Wrist Evaluation (PRWE) at 1 year.
