Early versus delayed repair of traumatic rotator cuff tears. Does timing matter on outcomes?

Introduction: The purpose of this study was to determine if delay (before or after 4 months) in repairing a symptomatic traumatic rotator cuff tear affected clinical outcome, re-rupture rates and use of interpositional dermal grafts. Methods: This was a case matched (age + tear size) series of patients who underwent an early (≤ 4 months) or delayed (> 4 months) rotator cuff repair following a traumatic tear. If a direct repair could not be achieved a dermal interposition graft was used. Outcomes were collected at a median time of 30 months post-operatively using the Oxford, Constant and EQ5D scores. Results: Twenty patients underwent rotator cuff repair within 4 months (1–4) of injury. Twenty age and cuff tear size—matched patients were identified who had undergone a delayed repair (4.1–24 months) after injury. We found no significant difference (p > 0.05) in patient reported outcomes scores between the early and delayed repair. [Oxford scores; Early 43(13–48), Delayed 45 (31–48); Constant scores; Early 73 (21–94), Delayed 73.5 (44–87); EQ5D; Early 0.75 (0.25–1), Delayed 0.77 (0.4–1)]. Time to full recovery was significantly longer (14 vs 33.8 months) for the delayed repair group (P > 0.05). When cuff tears were subdivided into < 3 cm tears or ≥ 3 cm tears, no significant difference outcome scores were founds. However, use of dermal interposition graft was 44% in delayed group for tears ≥ 3 cm. No grafts were used in early repair group. There was one symptomatic re-tear in our series which was in the early repair group. Conclusion: When compared to the delayed repair group, patients that underwent early repair of traumatic rotator cuff tears had shorter time of recovery, and less need for allograft augmentation for tears 3 cm or greater. However, at mid-term follow-up, this study found no difference in patient reported outcomes following early versus delayed repair of traumatic rotator cuff tears.
