Mean WOSI score (%) and (95% confidence intervals) for the stable shoulders compared with separate groups of unstable shoulders at the 10-year follow-up (n = 62)

^a Occasional: recurrent on one or more occasions that were associated with subjective instability, but the patients considered their shoulders to be stable and had no further problems for several years.

^b Recurrent on several occasions: the patients considered their shoulder to be unstable.

^c Reoperated: 8 patients, but 1 patient died before the 10-year follow-up.
