Secondary outcomes included functional scores, pain intensity, magnetic resonance imaging findings, and analgesic consumption.</p><p><strong>Results: </strong>Twenty-four patients were enrolled, and 22 completed 12-month follow-up. At 3 months, 8 out of 23 patients (35%) achieved the predefined 13-point CMS as minimal clinically important difference. Mean CMS improved from 62.4 at baseline to 72.2 at 3 months and 78.7 at 12 months (<i>P</i> < .001). The American Shoulder and Elbow Surgeons score improved from 47.3 at baseline to 68.5 at 3 months and 82.2 at 12 months. The Simple Shoulder Test improved from 8.8 to 9.7 at 3 months and 11.3 at 12 months. Pain scores decreased from 5.8 at baseline to 3.5 at 3 months and 2.1 at 12 months. Magnetic resonance imaging at 12 months showed improved tendon quality in 7 out of 20 evaluated patients (35%).</p><p><strong>Conclusions: </strong>Intratendinous porcine-derived type I collagen injections were associated with progressive improvements in shoulder function and pain over 12 months in this single-arm pilot study. Although the predefined minimal clinically important difference at 3 months was reached by a proportion of patients, functional scores showed continued improvement throughout follow-up. Magnetic resonance imaging findings showed improved tendon quality in part of the cohort, and no serious adverse events were recorded.</p><p><strong>Level of evidence: </strong>Level IV, prospective therapeutic case series.</p>","PeriodicalId":34631,"journal":{"name":"Arthroscopy Sports Medicine and Rehabilitation","volume":" ","pages":"e70114"},"PeriodicalIF":0.0,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13637793/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149115826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
