Purpose
Arthroscopic Bankart repair (ABR) provides satisfactory results for recurrent anterior shoulder instability, but the high recurrence rate post-ABR remain a concern. One of the adjunct procedures proposed to improve ABR results is arthroscopic rotator interval closure (ARIC). This study prospectively evaluated the outcomes of ABRs alone compared to combined ABR + ARIC and identified risk factors related to failure of each procedure.
Methods
Thirty-nine consecutive patients (mean age 23.1 (18.3–37.5) years; 37 males) underwent arthroscopic stabilization for recurrent anterior traumatic shoulder instability. Twenty patients underwent ABR alone and 19 underwent ABR + ARIC. Remplissage was added when glenoid engagement was observed during surgery. All patients were prospectively followed, and their postoperative courses were reviewed and functionally assessed at the last visit.
Results
The re-dislocation rate was higher in the ABR + ARIC group compared to the ABR only group at a mean follow-up of 4.2 (2–5.6) years (3 vs. 0, P = 0.06). More subluxations were found in the ABR only group (2 vs. 1, respectively; P = 0.58). The final limitation of range of motion (ROM) compared with the preoperative ROM was similar in both groups. Remplissage procedures were performed more often in the ABR only group [12 (60%) vs. 4 (21%), P = 0.013].
Conclusions
ARIC performed as an adjunct to ABR showed no superiority in attaining value-added stability compared to ABR alone. Adding a remplissage procedure may achieve better stability.
