Transfer of one particular tendon called the trapezius is becoming popular as a means of restoring function and improving pain in patients with massive rotator cuff tears. This tendon is appealing for transfer, as it has a similar line of pull to the infraspinatus (one of the rotator cuff tendons). There is currently no clear surgical consensus regarding the optimal treatment of patients with symptomatic massive irreparable rotator cuff tears that are appropriate candidates for joint salvage treatment, and no high level of evidence studies to guide clinical decision making have been published.\n\nA pilot study is required prior to the development of a full-scale trial to assess its feasibility and recruitment across clinical sites, to determine protocol adherence (errors in randomization), and patient retention over a 12-month period.\n\nThe main objective of this pilot trial is to assess a composite measure of feasibility including recruitment, protocol adherence, and patient retention at one-year. The secondary objectives, currently exploratory only, are to determine the clinical outcomes of lower trapezius tendon transfer versus arthroscopic rotator cuff partial repair and biceps tenodesis\u002Ftenotomy on clinical outcome measures, shoulder function, adverse events and reoperation rates at two-years.\n\nThis pilot study is a parallel-group multicentre randomized controlled trial with participating sites across Canada, and one site in the United States.",[82],"Massive Rotator Cuff Tear","NOT_YET_RECRUITING","2025-07-02",{"date":86,"type":87},"2025-07-04","ACTUAL",{"date":89,"type":76},"2025-08-01",{"date":91,"type":76},"2029-12-31",{"name":5,"class":6},1]
