PROMIS pain scores significantly improved in patients with IAT grades 1-3, with 5, 5, and 7 patients, respectively, in each subgroup. In this small series we only identified statistically significant improvements in PROMIS function (<i>P</i> = .031), and mobility (<i>P</i> = .009) scores were only observed in patients with grade 2 pathology. Sixteen of 17 patients (94.2%) were very satisfied with their procedure and would undergo it again.</p><p><strong>Conclusion: </strong>In this pilot study, we did not find preoperative MRI findings to correlate well with patient-reported outcome scores following MIS ZO.</p><p><strong>Level of evidence: </strong>Level IV, case series.</p>","PeriodicalId":12429,"journal":{"name":"Foot & Ankle Orthopaedics","volume":"10 1","pages":"24730114251322775"},"PeriodicalIF":0.0,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11898226/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143614323","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}
