The Sponsor decided that the CE marking would not be renewed, and therefore there was no longer a need to continue the study as the data was no longer necessary.

To report the outcomes of a series of patients with recurrent anterior and/or posterior shoulder instability who underwent surgical repair of the affected labrum using the SureLock all-suture anchor.

Patient-reported outcomes data have been collected among patients undergoing shoulder labrum repair with SureLock all-suture anchors from January 2014 to June 30, 2020. These patients have completed clinical and quality-of-life outcome instruments pre-operatively, and have been stored securely in the OBERD database. Pre-op scores will be compared to post-op scores and analyzed using a one-way ANOVA test with a post-hoc Scheffe procedure.

Patient identifying information will be removed and de-identified codes will be used. Any new prospective data gathered prospectively for the purposes of this study will be entered and stored securely as above.

Data collection forms will consist of the following Patient-Reported Outcome Surveys: WOSI Index, ASES Shoulder Score, and the SF-12.
