BACKGROUND: The surgical repair of shoulder pathologies, including rotator cuff disease and acromio-clavicular joint @entity625 , have undergone many technical advances. However the debilitating postoperative stiff shoulder remains a common and significant complication of these surgeries, occurring in 4.9 to 23.2 % of @entity1 undergoing rotator cuff repairs. The pathology of the pathological postoperative stiff shoulder and its associated condition "frozen shoulder" are poorly understood and both lack formal objective clinical diagnostic criteria. Additionally, although factors associated with the development of @entity2585 have been well described, multiple studies looking at predictors of postoperative stiff shoulder have produced conflicting results. It has been hypothesised that @entity158 in the postoperative period, and @entity308 may be predictors of the development of postoperative stiff shoulder. METHOD: A prospective cohort study involving 132 consecutive @entity1 . Preoperatively, @entity1 undergoing arthroscopic subacromial decompression and/or excision of the distal clavicle and/or rotator cuff repair will complete questionnaires about their levels of @entity158 using a numerical rating scale from 0 to 10, and answer a @entity1 Health Questionnaire - 9 @entity308 questionnaire. Postoperatively, the @entity1 ' @entity158 levels will be self-assessed at two, five and seven days and weeks four, seven and ten. They will complete the @entity308 questionnaire twice, at the time of their routine first and final postoperative appointments with the treating surgeon. At the final appointment, approximately three months postoperatively, the treating surgeon will clinically diagnose @entity1 as having a postoperative stiff shoulder or not. Their shoulders' range of motion will be measured. The incidence of postoperative stiff shoulder will be determined, both @entity158 and @entity308 will be analysed as predictors for its development and incidences determined by different objective criteria will be compared. DISCUSSION: This trial will add to clinical understanding of the postoperative stiff shoulder by providing further insight into the incidence of this condition following shoulder surgery and assessing whether perioperative @entity158 and @entity308 can be used as clinical predictors of postoperative stiff shoulder or markers for possible early intervention. This study will also allow the comparison of incidences determined by different objective criteria in the same cohort. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry (ANZCTR).
