Key Finding
For calcific tendinitis patients without rotator cuff tears, surgical treatment provided superior pain relief and functional improvement compared to conservative care including acupuncture, though recovery time was significantly longer with surgery.
Researchers compared surgery versus non-surgical treatments for calcific tendinitis, a painful shoulder condition caused by calcium deposits in the rotator cuff tendons. This study followed 180 patients between 2017 and 2021, with 103 receiving non-surgical care and 77 undergoing arthroscopic surgery after six months of failed conservative treatment.
The non-surgical treatment group received various therapies including anti-inflammatory medications, acupuncture, steroid injections, shock wave therapy, and ultrasound-guided needle aspiration. The surgical group had arthroscopic procedures to remove calcium deposits.
Overall, both treatment approaches showed similar improvements in pain and shoulder function scores. However, an important distinction emerged: for patients without rotator cuff tears, surgery provided better pain relief and functional improvement compared to non-surgical treatments, though surgical patients took significantly longer to recover (87 days versus 30 days on average).
Interestingly, the size of calcium deposits, number of affected tendons, and how deeply calcium penetrated the tendon tissue did not affect recovery time. The presence of rotator cuff tears was the only factor that significantly impacted complete functional recovery, regardless of treatment method.
What this means for patients: If you have calcific tendinitis without a rotator cuff tear, both surgical and non-surgical approaches can help, though surgery may provide better results at the cost of longer recovery time. Acupuncture was included as part of the comprehensive non-surgical treatment protocol in this study, supporting its role as one component of conservative care for this condition. To explore acupuncture for shoulder pain, seek a licensed acupuncturist with experience treating musculoskeletal conditions.
This retrospective cohort study (n=180) compared arthroscopic surgery versus multimodal conservative treatment for symptomatic shoulder calcific tendinitis. The conservative arm (n=103) included NSAIDs, acupuncture, corticosteroid injections, extracorporeal shock wave therapy, and ultrasound-guided needle aspiration. The surgical cohort (n=77) underwent arthroscopy after six months of failed conservative care.
After propensity score matching, no significant differences emerged in Constant-Murley score changes (48.1±25.4 vs 49.0±22.8, p=0.950) or VAS improvements (4.9±2.3 vs 4.5±1.9, p=0.860) between groups overall. However, subgroup analysis of patients without rotator cuff tears showed significantly better outcomes with surgery (Constant-Murley: 52.93±25.18 vs 42.13±22.35, p=0.012; VAS: 5.21±2.06 vs 3.81±1.98, p<0.001), though recovery time was prolonged (86.92±138.56 vs 30.42±54.97 days, p=0.016).
Calcium deposit size, tendon infiltration depth, and multiple tendon involvement did not correlate with recovery outcomes. Rotator cuff tears were the sole predictor of incomplete functional recovery. Clinical takeaway: Conservative multimodal treatment including acupuncture remains first-line, with surgery reserved for refractory cases without concurrent rotator cuff pathology.
