Background: Outcome reporting following flexor tendon repair has historically concentrated on range of movement. Recently, there has been an increase in the use of patient-reported outcome measures (PROMs). At present, there is no agreed set of outcomes to report following flexor tendon repair. The aim of this study is to review outcome reporting practices after flexor tendon repair in zones 1 and 2. Methods: A search of Ovid MEDLINE, Ovid EMBASE and Cumulative Index to Nursing and Allied Health Literature (CINAHL) between 1 January 1980 and 31 December 2019 was performed to identify the studies that reported outcomes following the repair of flexor tendons in zones 1 and 2. Study characteristics and data with regard to the reporting of eight outcome domains was extracted: functional outcome (quantitative), functional outcome (subjective), activities of daily living (ADL), satisfaction/quality of life, post-treatment recovery, resources, aesthetics and safety. Results: A total of 94 out of 4,118 articles identified were included in the review. All studies reported range of motion using 17 different methods of measurement. Eleven studies defined measurement methods incorrectly or unclearly. Only 16 studies reported PROMs, with only one reporting data on assessment of quality of life. Eighteen studies reported time away from employment. Minimal data on resource utilisation and aesthetics were included. Conclusion: This review highlights wide heterogeneity and paucity of data reporting clinical outcomes of flexor tendon surgery. The development of a core outcome set that would ensure essential outcomes are correctly defined, measured and reported is required. Level of Evidence: Level IV (Prognostic).
