PURPOSE: To compare the results two to three years after intervention, using either surgical or non-operative treatment. METHODS: Eighty-seven @entity1 with @entity5818 ( @entity5818 ) were randomised into open acromioplasty (OS group), arthroscopic acromioplasty ( @entity5427 group) or physiotherapy (PT group) treatment. The assessments comprised the Constant score, the Watson and Sonnabend score, the SF-36 evaluation and a clinical examination performed by an independent observer. Fifty-five @entity1 attended the clinical follow-up. RESULTS: The groups were comparable at baseline in terms of demographics and clinical assessments. No significant differences in terms of the clinical assessments or health-related quality of life (QoL) were found between the study groups at follow-up. The Constant score had improved significantly at follow-up in both the OS group and the @entity5427 group (p  =  0.003 and 0.008, respectively). At follow-up, the OS group revealed improved strength compared with before intervention (p  =  0.012). All groups revealed a significantly improved internal rotation (OSG p  =  0.01, ASG p  =  0.005, PTG p  =  0.004). The SF-36 was significantly improved in some scales within all three groups. The Watson and Sonnabend score was significantly improved in 12/14 questions for the OS group, in 5/14 questions for the @entity5427 group and in 6/14 for the PT group (p  <  0.02 OS group vs. @entity5427 group, p  <  0.05 OS group vs. PT group). CONCLUSION: In this randomised study, the Constant score, other clinical assessments and subjective health-related QoL revealed no significant differences between the 3 groups two to three years after intervention in @entity1 with @entity5818 . The OS group showed a greater improvement over time. LEVEL OF EVIDENCE: CT with low follow-up rate, Level II.
