Long-term prognoses of patients with and without re-rupture afterarthroscopic rotator cuff repair

摘要

[Purpose] We followed-up patients who underwent arthroscopic rotator cuff repair (ARCR)for 2 years to assess the prognosis of rotator cuff tears and compared the outcomes of thepatients with and without re-rupture. We also examined the usefulness of Shoulder36, aself-assessment tool, for assessing the long-term prognosis in patients undergoing ARCR.[Participants and Methods] We included 28 patients who received occupational therapy pre-and post-ARCR between April 2012 and August 2015 and categorized them based on theoccurrence of re-rupture. We followed-up on their prognoses for 2 years using physicalexamination and Shoulder36 assessment. [Results] Re-rupture occurred in five patientswithin 3 months of treatment. During the 2 year follow-up, the control group showed asignificant improvement in pain and bi-directional active range of motion during physicalassessment and in five out of six domains during Shoulder36 assessment. In contrast, there-rupture group showed significant differences for only three domains of the Shoulder36assessment twelve months after surgery. [Conclusion] We confirmed the long-term functionalimprovement and maintenance in the re-rupture group, suggesting that continuedrehabilitation, compensatory movements, and detailed guidance on daily life activities arerequired for patients after ARCR. Furthermore, Shoulder36 can be useful for assessing theprognosis of patients with and without re-rupture.
