Outcomes After Repair of Acute Rotator Cuff Tears
An observational study of Rotator Cuff Tear, run by University Hospital, Linkoeping.
Trial summary
Few studies are considering acute traumatic rotator cuff tears in previously asymptomatic patients. The purpose of the current study was to investigate if delay of surgery, age at repair and the number of cuff tendons involved affected the structural and clinical outcomes.

Study population: A retrospective review of our computerized database identified 49 patients repaired at our institution between May 2004 until May 2009 due to acute traumatic rotator cuff tears. 42 patients who fulfilled the inclusion criteria, were willing to participate in a follow-up evaluation after written and oral informed consent.
Who may be able to join
- significant trauma to the shoulder
- sudden onset of symptoms
- asymptomatic in the shoulder before trauma
