Long-term outcomes of open modified inferior capsular shift for traumatic anterior shoulder instability: over 20 years of follow-up

We investigated long-term outcomes of the open modified inferior capsular shift procedure for traumatic anterior shoulder instability. Our data suggest that recurrent instability might result from new trauma even if a long time has passed since the open modified inferior capsular shift procedure, so follow-up should be continued as long as possible after surgery. As in other reports, satisfaction was high and clinical scores were good. We thus believe this surgical method offers good results even after more than 20 years.
