Gutter impingement is a common yet largely underreported complication following total ankle arthroplasty (TAA). As the use of TAA exponentially increases, an understanding of how to both recognize and manage gutter impingement is vital to the optimization of post-operative care. Narrowing of the medial and lateral ankle gutters can arise from a variety of causes, including implant malalignment, scar tissue formation and hypertrophic bone formation, ultimately leading to residual pain following surgery. The incidence of this pathology and its respective management varies greatly within the available literature. The purpose of this study is to review the incidence, treatment approaches and outcomes of gutter impingement following TAA. Eight studies were analyzed which included 1456 patients, of which 130 were treated for gutter impingement at an average of 18 months following index TAA. The mean age of patients across all studies was 62.9 years, with an average follow up period of 40.6 ± 23.1 months. Open debridement was noted to be the most common surgical approach (50.8 %) followed by arthroscopic debridement (37.7 %). Conservative treatment was only used in 9.2 % of cases. This review demonstrates the underreporting of gutter impingement following total ankle arthroplasty and highlights the of lack of standardized treatment. Future prospective studies are warranted in efforts to optimize patient outcomes in the management of gutter impingement.</div></div><div><h3>Level of Evidence</h3><div>Level III Systematic Review</div></div>","PeriodicalId":73047,"journal":{"name":"Foot & ankle surgery (New York, N.Y.)","volume":"5 3","pages":"Article 100508"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144860728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the United States, there are over 2 million ankle injuries annually (1). Historically, the treatment of bimalleolar equivalent fractures includes the fibular fracture, and use of a syndesmotic fixation if syndesmotic laxity and medial widening are observed. This article argues that deltoid ligament repair should be done concomitantly with anterior medial capsule repair in order to fully address rotary laxity. The centerpiece of deltoid injury with capsule injury diagnosis is the widening of the medial clear space >4 mm and/or >1 mm difference than the contralateral limb on AP radiographs (1–7). We suggest that anterior medial capsule repair must be done with the deltoid ligament repair. We present a case of a Weber B fracture with uncertain deltoid involvement on pre-operative radiographs, for which a deltoid rupture with capsule involvement was determined intraoperatively with appropriate stress radiographs taken under general anesthesia. Repair of the deltoid using a low cost, non-intraarticular implant with concomitant repair of the anterior-medial capsule of the ankle joint was utilized. This medial ankle repair, in addition to ORIF of the fibula resulted in a satisfactory clinical and radiographic outcome.</div></div>","PeriodicalId":73047,"journal":{"name":"Foot & ankle surgery (New York, N.Y.)","volume":"5 3","pages":"Article 100509"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144253425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
