“…5 The current authors found the average age of patients undergoing TAA to be 62.5 years, which is slightly older than prior studies showing an average range of 50 to 60 years. 6,7,9,[17][18][19][20] Although the current study does not have survival data, an older average population age is often associated with a higher survival rate. Spirt et al 21 found that a higher survival rate (89%) in patients older than 54 years compared with patients younger than 54 years (74%).…”

The number of total ankle arthroplasties (TAAs) performed annually in the United States has increased. The purpose of this study was to evaluate the in-patient demographics, complications, and readmission rates of patients after TAA at academic medical centers in the United States. The University HealthSystems Consortium administrative database was searched for patients who underwent TAA in 2007 to 2011. A descriptive analysis of demographics was performed, followed by a similar analysis of clinical benchmarks, including hospital length of stay, hospital direct cost, in-hospital mortality, and 30-day readmission rates. The study included 2340 adult patients with a mean age of 62 years (47% men and 53% women) who underwent TAA. The majority of patients were Caucasian (2073; 88.5%). Average hospital length of stay was 2.2±1.26 days. Average total direct cost for the hospital was $16,212±7000 per case, with 49.7% of patients having private insurance. In-hospital mortality was less than 1%, and overall complications were 1.4%. Complications after discharge included deep venous thrombosis (2.3%), reoperation (0.7%), and infection (3.2%). A readmission rate of 2.7% within the first 30 days from the time of discharge occurred. Total ankle arthroplasty in the United States is a relatively safe procedure with low overall complication rates. Patients who are male, have a history of community-acquired pneumonia, and have a larger number of preoperative comorbidities had a significant increased risk of developing 1 complication within 30 days of surgery.

“…MobilityÔ prostheses had been implanted and, with 33% of the total ankle replacements recorded in the registries, represents the most frequently implanted prosthesis worldwide. However, just as with all total ankle replacements studied, the short-term incidence of revision increases with longer term follow-up, and the most common failure mechanisms of aseptic osteolysis and component subsidence predominantly involving the talar component become more evident (41)(42)(43)45,46,48,49,51). Accordingly, the value of including total ankle replacement in national joint registries is obvious.…”

Two-Year Outcomes of MOBILITY Total Ankle Replacement

Abstract: Our findings suggest that early outcomes after total ankle replacement for patients with posttraumatic osteoarthritis are comparable with those for patients with osteoarthritis and rheumatoid arthritis.
