There is clear evidence to support removal of the calcific deposit in patients with calcific tendonitis, however, there is conflicting evidence as to whether concomitant subacromial decompression (SAD) is of benefit to the patient. The aim of this study was to conduct a prospective double blind randomised control trial to assess the independent effect of SAD upon the functional outcome of arthroscopic management of calcific tendonitis.

During a four year period 80 patients (power calculation was performed) were recruited to the study who presented with acute calcific tendonitis of the shoulder. Forty patients were randomised to have SAD and 40 were randomised not to have a SAD in combination with arthroscopic decompression of the calcific deposit. All surgery was performed by the senior author who was blinded to the functional assessment of the patients.

There were 21 male and 59 female patients with a mean age of 48.9 (32 to 75) years. The pre-operative short form 12 physical component summary (PCS) was 39.8 and the mental component summary was 52.6, disability arm should and hand (DASH) score was 34.5, and the Constant score (CS) was 45.7. Both groups had a significant improvement in the PCS, DASH, CS at 6 weeks and at one year compared to their pre-operative scores (p<0.001). There were no significant differences demonstrated between the groups for any of the outcome measures assessed at 6 weeks or at one year.

SAD should not be routinely performed as part of the arthroscopic management of acute calcific tendonitis.
