Methods: This retrospective single-centre cohort included 93 patients. All underwent ultrasound-guided needling of the calcific deposit without lavage. Treatment allocation reflected routine clinical practice and was non-randomised. Patients with Gartner type 1\u20132 calcifications received either PRP or corticosteroid injections, whereas type 3 patients were treated with needling + PRP or conservative management. Outcomes were VAS pain, Constant\u2013Murley Score (CMS), QuickDASH, and radiographic resorption, assessed at baseline, 2 weeks, 6 months, and 12 months. Results: In Gartner type 1\u20132 disease, needling followed by PRP resulted in greater 12-month pain reduction than needling followed by corticosteroid (both p &lt; 0.05), while improvements in CMS, QuickDASH, and 1-year complete resorption rates were similar between groups. Gartner type 3 calcifications showed substantial clinical improvement irrespective of treatment modality, but the combined needling + PRP intervention was associated with a higher rate of complete radiographic resorption at 2 weeks than conservative care (72.2% vs. 13.3%; p = 0.001). Four patients (4\/93, 4.3%) required arthroscopic surgery (three corticosteroid, one PRP). Conclusions: In Gartner type 1\u20132 calcific tendinitis, ultrasound-guided needling followed by PRP was associated with greater 12-month pain reduction than needling followed by corticosteroid, whereas functional and 1-year radiographic outcomes were comparable. In symptomatic Gartner type 3 disease, the combined needling + PRP intervention was associated with faster early radiographic resorption but did not demonstrate superior long-term clinical outcomes; conservative treatment remains appropriate for patients with tolerable symptoms.<\/jats:p>","DOI":"10.3390\/jcm15155848","type":"journal-article","created":{"date-parts":[[2026,7,27]],"date-time":"2026-07-27T09:47:41Z","timestamp":1785145661000},"page":"5848","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Ultrasound-Guided Needling Without Lavage Followed by Platelet-Rich Plasma or Corticosteroid in Rotator Cuff Calcific Tendinitis: A Comparative Cohort Study"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7418-4207","authenticated-orcid":false,"given":"Idris","family":"Demirtas","sequence":"first","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Mersin City Training and Research Hospital, 33240 Mersin, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00d6ner","family":"Kilinc","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Mersin City Training and Research Hospital, 33240 Mersin, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ali Nadir","family":"Tanrikulu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Mersin City Training and Research Hospital, 33240 Mersin, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Serhat","family":"Elci","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Sultan Private Hospital, 21080 Diyarbak\u0131r, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-9799-4994","authenticated-orcid":false,"given":"Yavuzhan","family":"Altin","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Dr. Ersin Arslan Training and Research Hospital, 27090 Gaziantep, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1770-0276","authenticated-orcid":false,"given":"Fatih","family":"Gunaydin","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Mersin City Training and Research Hospital, 33240 Mersin, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"733","DOI":"10.1007\/s00132-011-1817-3","article-title":"Calcific tendinitis of the shoulder","volume":"40","author":"Diehl","year":"2011","journal-title":"Orthopade"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2978","DOI":"10.1002\/art.24845","article-title":"Prognostic factors in nonoperative therapy for chronic symptomatic calcific tendinitis of the shoulder","volume":"60","author":"Ogon","year":"2009","journal-title":"Arthritis Rheum."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"381","DOI":"10.1007\/s00590-016-1839-y","article-title":"Extracorporeal shock wave therapy, ultrasound-guided percutaneous lavage, corticosteroid injection and combined treatment for the treatment of rotator cuff calcific tendinopathy: A network meta-analysis of RCTs","volume":"27","author":"Arirachakaran","year":"2017","journal-title":"Eur.
