Preoperative condition seen as key in return to baseline function after anterior shoulder instability
Rather than surgical factors, data presented here indicate patient preoperative condition is the most important factor in return to baseline function in the short-term period following anterior shoulder instability.
Of the 278 patients who had complete preoperative and postoperative ROM and strength data available, 138 (50%) returned to baseline while 133 (50%) did not. Age, Beighton score, Western Ontario Shoulder Instability (WOSI) score, SF-36 general health scores and duration of symptoms were identified by univariate analysis as significant factors for anterior shoulder instability. Of these, a multivariate model showed significant differences in age, SF-36 general health scores and Beighton score.
