Arthroscopic Treatment Results of Triangular Fibrocartilage Complex Tears in Adolescents: A Systematic Review

Injury to the triangular fibrocartilage complex (TFCC) may cause chronic wrist pain and instability if left untreated. The current literature of adult cases suggests that arthroscopic treatment offers favorable outcomes and is associated with a low complication rate. This systematic review evaluated the outcomes of arthroscopic TFCC surgery in adolescents.

A PRISMA-guided literature search of PubMed, Medline, Embase, Scopus, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Cochrane Clinical Answers was conducted in May 2020. All studies reporting on (1) arthroscopic TFCC repair or debridement in (2) patients under the age of 19 years with (3) a minimum case number of four patients were extracted by two independent observers. The level of evidence of each study was assessed according to the Oxford Centre for Evidence-Based Medicine, and study quality was graded according to the Modified Coleman Methodology Score and the MINORS criteria. Clinical outcome scores, functional parameters, and any complications were reviewed.

The selected search terms initially resulted in a total of 986 possible articles. The authors eventually identified eight papers (all LoE IV) for inclusion in this systematic review. A total of 254 patients with verified TFCC tears and a mean age of 16 years (range, 7-19) received arthroscopic repair (162 patients, 67.1% of total) or debridement (77 patients, 29.7% of total). Arthroscopic treatment resulted in low pain levels, high patient satisfaction, and a fast return to sport. Complications overall were sparse and consisted mainly of persistent wrist pain (n = 31) and temporary paresthesia (n = 6) of the dorsal sensory branch of the ulnar nerve. Recurrent tears were sparse, with only four reported cases due to sports participation.

Wrist arthroscopy is a reliable surgical option for treating TFCC tears in adolescents. The results obtained are comparable to those published in the literature. However, the variety of repair techniques and the low level of evidence across all included articles demand further prospective studies.
