Patients without previous surgery treated with RSA for fractures had better functional results than patients who had undergone previous surgery.

Purpose The aim of this study is to evaluate clinical outcome for arthroscopic removal of calcium deposit without acromioplasty and rotator cuff repair for patients with ultrasound-diagnosed arch-shaped calcifying tendinitis of the rotator cuff (type I), homogenic (x-ray) with chronic pain. Methods We retrospectively reviewed 50 patients with homogenous, arch-shaped calcifying tendinitis, suffering from chronic pain and who underwent arthroscopic treatment and 50 patients with the same type of tendinitis treated conservatively. All patients had calcium deposit located in supraspinatus tendon, pre-operatively and post-operatively evaluated by ultrasound. Clinical outcome was assessed by using Quick DASH, UCLA, and VAS score. Results There were 29 male and 71 female patients; none had bilateral involvement. We divided patients into group A-operatively treated-and group B-conservatively treated-by shock wave therapy. Patients from group A had higher improvement of all used tests, QDash (from 19.3 to 2.7), UCLA (from 10 to 34), and VAS score (from 3 to 0) when compared with group B. Conclusion Patients with arch-shaped calcium deposits and acoustic shadow have better results after arthroscopic treatment than the conservative one. There was no need for acromioplasty or tendon repair. The lack of performing the same did not have any impact on the post-operative rehabilitation and recovery.
