Systematic review on complications of total Ankle replacement using Mobility ankle

Abstract

Arthrodesis ankle has been the gold standard treatment for severe ankle arthritis. However, whereas isolated ankle arthrodesis might address immense pain at the ankle, it might not sufficiently address the associated problems and ongoing changes in the neighboring joints, and this procedure is also associated with a high complication rate. Total ankle replacement (TAR) was developed to provide an alternative to ankle arthrodesis for treating severe ankle arthrosis, with the inherent advantage of preserving joint motion, reducing limping and protecting other joints. The ideal candidate for ankle arthroplasty has been described as an older, thin, low-demand individual with minimal deformity and retained ankle range of motion. Indications for total ankle arthroplasty are primary osteoarthritis, secondary systemic osteoarthritis, post traumatic osteoarthrosis. While contraindications are infection, neuropathy, a vascular necrosis of the talus and lower limb neurological dysfunction. Ankle replacement was first attempted in the 1970s, but poor results led to it not being investigated again until the late 1980s and early 1990s, when designs which more closely Summary 66 replicated the natural anatomy of the ankle showed improved clinical outcomes. Ankle replacement is still seen as an inferior procedure to ankle fusion by many in the orthopedic community but more encouraging results and better patient selection have led to a renewed interest in its potential. There are many generations of total ankle arthroplasty. The first generation of TARs was two part systems the polyethylene part was placed in the tibia and the metal part in the talus all were secured using cemented fixation and could be divided into constrained and unconstrained. The second generation includes many types of prosthesis for example the Agility ankle prosthesis, Buechel Pappas, the STAR and the Mobility ankle.
