Aims. This scoping review aims to identify patient-related factors associated with a poorer outcome following total ankle arthroplasty (TAA). Methods. A scoping review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A computer-based literature search was performed in PubMed, Embase, Cochrane trials, and Web of Science. Two reviewers independently performed title/abstract and full-text screening according to predetermined selection criteria. English-language original research studies reporting patient-related factors associated with a poorer outcome following TAA were included. Outcomes were defined as patient-reported outcome measures (PROMs), perioperative complications, and failure. Results. A total of 94 studies reporting 101,552 cases of TAA in 101,177 patients were included. The most common patient-related risk factor associated with poorer outcomes were younger age (21 studies), rheumatoid arthritis (17 studies), and diabetes (16 studies). Of the studies using multivariable regression specifically, the most frequently described risk factors were younger age (12 studies), rheumatoid arthritis (eight studies), diabetes (eight studies), and high BMI (eight studies). Conclusion. When controlling for confounding factors, the most commonly reported risk factors for poor outcome are younger age, rheumatoid arthritis, and comorbidities such as diabetes and increased BMI. These patient-related risk factors reported may be used to facilitate the refinement of patient selection criteria for TAA and inform patient expectations.

Introduction:. In a consecutive series of 71 arthroscopic subtalar arthrodeses performed between 2004 and 2011, 14 also involved arthroscopic decortication of the talonavicular joint (double arthrodesis) and 4 the subtalar, talonavicular and calcaneocuboid joints (triple arthrodeses). Methods:. We examined complications, union rates in all 18 patients and clinical outcomes in 16 for whom this was the sole procedure. Results:. Mean age was 62 (45–78). Two talonavicular joints failed to unite and a third patient suffered a diabetic Charcot midfoot neuro-arthropathy. These patients' outcomes were classified as poor. Two patients underwent planned major ankle or midfoot surgery in addition to arthroscopic double arthrodeses. These joints united but these patients were not included in the clinical review to avoid confounding outcomes. Mean follow-up for the remaining 13 patients was 4.4 (1.75–7.5) years. There were no immediate perioperative complications. All 4 patients with triple fusions united with good or excellent outcomes. The nine patients receiving double arthrodesis united with 8 good or excellent outcomes. The remaining patient reported good deformity correction and stability but disappointing pain relief, (classification poor). Conclusions:. Double and triple arthrodeses remain valid salvage options for painful arthrosis and severe deformity. Preservation of the calcaneocuboid joint permits a relative lateral column lengthening when correcting planovalgus deformity. Arthroscopic surgery offers preservation and protection of soft tissues and reduces wound tension. The sinus tarsi approach permits good visualisation and decortication of the triple joints and rotatory correction of deformity. This technique is not appropriate when there is extensive bone loss requiring block bone grafting. Early complications are reduced and late complications such as non-union and arthrosis of adjacent joints seem similar to those reported in studies on open arthrodeses

Aims

Arthroplasty has become increasingly popular to treat end-stage ankle arthritis. Iatrogenic posterior neurovascular and tendinous injury have been described from saw cuts. However, it is hypothesized that posterior ankle structures could be damaged by inserting tibial guide pins too deeply and be a potential cause of residual hindfoot pain.

Aims

Total ankle arthroplasty (TAA) has become the most reliable surgical solution for patients with end-stage arthritis of the ankle. Aseptic loosening of the talar component is the most common complication. A custom-made artificial talus can be used as the talar component in a combined TAA for patients with poor bone stock of the talus. The purpose of this study was to investigate the functional and clinical outcomes of combined TAA.
