Correlation and multiple regression analyses were performed.</p><p><strong>Results: </strong>Mean age was 40.3 ± 8.6 years, and 61.7% of patients were male. Anatomical reduction was achieved in 78.3% of patients. Those with anatomical reduction had significantly higher AOFAS, FADI, and SF-36 scores (p < 0.05). Plantigrade angle correlated positively with AOFAS and FADI and negatively with VAS. Greater MDA was associated with poorer functional outcomes.</p><p><strong>Conclusion: </strong>Postoperative radiological axis parameters, particularly the plantigrade angle and metatarsal declination angle, showed significant correlation with early functional outcomes after tibial pilon fracture surgery. Precise radiological measurements are essential for predicting recovery and guiding treatment strategies.</p><p><strong>Level of evidence: </strong>Level III, retrospective cohort study.</p>","PeriodicalId":50191,"journal":{"name":"Journal of Foot & Ankle Surgery","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145228656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
