“…Other authors agreed with performing realignment procedures at the same time as implant arthroplasty [14,24,25,27]. Cenni et al [36] reported ankles with larger preoperative anterior subluxation showed the talar component positioned more posteriorly over the talus postoperatively. However, Hobson et al [37] compared patients with a preoperative hindfoot deformity <10°to a group with greater deformity (11-30°) and found no difference in ROM, complication and survival rate.…”

Purpose The purpose of this study was to provide cumulative data about the intermediate to long-term outcome of Scandinavian total ankle replacement (STAR) in the literature and to provide a summary of survival rate, implant failure rate and reasons. Methods A comprehensive search for all relevant articles published in English and German from January 1995 to May 2011 was conducted. Two reviewers evaluated each study to determine whether it was eligible for inclusion and, if so, collected data of interest. The intermediate to longterm outcomes were determined. Evidence-based metaanalytic pooling of results across studies was performed to determine survival and failure rates. Results Sixteen primary studies with 2,088 implants were identified. The mean American Orthopaedic Foot and Ankle Society (AOFAS) score was 77.8 points, and the mean Kofoed ankle score was 76.4 points. The pooled mean five year survival rate was 85.9% [95% confidence interval (CI) 80.9-90.3], and the pooled mean ten year survival rate was 71.1% (95% CI 60.9-81.5). Pooled failure rate was 11.1% (95% CI 7.6 -14.9), with a mean follow-up time of 52 months; 41% failed within one year of initial operation. The first three reasons associated with implant failure were aseptic loosening (5.2%), malalignment (1.7%) and deep infection (1.0%). Conclusions We found that STAR prosthesis achieved encouraging results in terms of intermediate to long-term outcome. The five and ten year survival rates were acceptable. However, the failure rate was still high. The major reasons for implant failure were aseptic loosening and malalignment. Maybe the increase of surgeons' experience and patient selection could improve outcomes and decrease failure rate.

A variety of surgical procedures are utilized for management of ankle osteoarthritis. The most common etiology in patients with ankle osteoarthritis is post-traumatic often resulting in asymmetric ankle osteoarthritis with concomitant valgus or varus deformity. A substantial part of tibiotalar joint is often preserved, therefore, in appropriate patients, jointpreserving surgery holds the potential to be a superior treatment option than joint-sacrificing procedures including total ankle replacement or ankle arthrodesis. This review is designed to describe indications and contraindications for single-stage supramalleolar realignment surgery. Complications associated with this type of surgery and postoperative outcome are highlighted using recent literature.

“…Realignment surgery may also be performed before ankle joint-sacrificing surgeries like ankle arthrodesis and total ankle replacement. It has been shown, that biomechanical properties and clinical outcomes of total ankle replacement depend on alignment and position of prosthesis components [28][29][30].…”

Patients with varus or valgus hindfoot deformities usually present with asymmetric ankle osteoarthritis. In-vitro biomechanical studies have shown that varus or valgus hindfoot deformity may lead to altered load distribution in the tibiotalar joint which may result in medial (varus) or lateral (valgus) tibiotalar joint degeneration in the short or medium term. The treatment of asymmetric ankle osteoarthritis remains challenging, because more than half of the tibiotalar joint surface is usually preserved. Therefore, joint-sacrificing procedures like total ankle replacement or ankle arthrodesis may not be the most appropriate treatment options. The shortand midterm results following realignment surgery, are very promising with substantial pain relief and functional improvement observed post-operatively. In this review article we describe the indications, surgical techniques, and results from of realignment surgery of the ankle joint in the current literature.
