Ankle replacement arthroplasty (Subscribe)  

We performed 52 cemented ankle arthroplasties for painful osteoarthritis (OA) (25) or rheumatoid arthritis (RA) (27) using an ankle prosthesis with a near-anatomical design.
We assessed the patients radiologically and clinically for up to 14 years using an ankle scoring system. The preoperative median scores were 29 for the OA group...

Ankle replacement surgery has been available for over two decades; however, it is a far less common procedure than hip or knee arthroplasty owing to the less frequent incidence of osteoarthritic ankle pathology. The majority of ankle osteoarthritis is secondary to trauma. Unlike idiopathic osteoarthritis this tends to occur in...

Norwegian Arthroplasty Register has been registering ankle replacements since 1994, but no analysis of these data has been published to date. Here we report data on the use of total ankle replacements and the revision rate in the Norwegian population over a 12-year period.
The overall 5- year and 10-year survival...

The aim of this study was to document and evaluate the early results of a nationwide series of total ankle replacements (TARs) performed using second- and third-generation implants.
RESULTS: 202 total ankle replacements were performed in 183 patients. 14 prostheses (7%) failed. The overall cumulative 5-year failure-free rate was 86%....

A systematic review of intermediate and long-term outcomes for total ankle replacement found excellent or good results in 82% of cases who received a second-generation ankle device compared to 72% of cases treated with ankle fusion. In addition, total ankle replacement resulted in a lower revision rate than fusion, according to...

Of the 531 prostheses implanted, 101 had been revised by June 15, 2006. The overall survival rate at 5 years was 0.78 (95%CI: 0.74-0.82). For the three surgeons who had inserted the majority of the STAR ankles, the survival rates became significantly higher after the first 30 cases had been...

“Significant uncertainty exists about the proper role of ankle arthroplasty in the treatment of ankle arthritis,” said Nelson Fong SooHoo, MD, of the UCLA Center for Surgical Outcomes and Quality, who presented the results of a study comparing the reoperation rates of ankle arthrodesis and ankle replacement during the American...

An interview with Jonathan T. Deland, MD
This “end stage” arthritis results in pain, combined with loss of function and mobility - severely limiting normal activity. When this end stage is reached and non-operative options (such as medication, injections, and bracing) have been exhausted, patients are presented with three methods of...

In an investigation called "revolutionary" by American Orthopaedic Foot and Ankle Society (AOFAS) Immediate Past President Robert B. Anderson, MD, researchers found better function with total ankle replacement compared to ankle fusion in a 2-year prospective controlled trial using an uncemented, mobile-bearing total ankle device.
Prospective study of a TAR device...

Total Ankle Replacement Surgery
Conclusion Total ankle replacement surgery is a safe and effective treatment option for select patients with ankle arthritis. In many patients total ankle replacement surgery substantially improves function, reduces pain, and allows for an improved quality of life. Patient mobility and quality of life factors contribute to longer...

Total ankle arthroplasty provides an alternative to arthrodesis for management of ankle arthritis. What is the outcome of total ankle arthroplasty implants currently in use? We conducted a systematic literature search of studies reporting on the outcome of total ankle arthroplasty.
How successful are current ankle replacements?: a systematic review of...

Ankle arthroplasty is increasingly used to treat advanced ankle arthritis. Earlier prostheses have given way to second-generation implants, on which we are accumulating medium-term data. The Scandinavian Total Ankle Replacement (STAR) is a three-component uncemented implant in wide use in Europe and the only mobile-bearing prosthesis with conditional approval in...

The number of studies reporting on outcomes after total ankle arthroplasty is continuously increasing. As the use of valid outcome measures represents the cornerstone for successful clinical research, we aimed to identify the most frequently used outcome instruments in ankle arthroplasty studies and to analyze the evidence to support their...

Ankle joint replacement is at a more experimental stage than the well-established replacement operations for hip and knee joints. Whereas the hip is a ball in socket joint and the knee is fundamentally a hinge joint, the ability of the ankle and forefoot to flex, extend, invert and evert makes is...

Ankle arthritis differs from that of the hip and knee in that it is most commonly caused by traumatic injury (rather than degeneration or inflammation) and predominantly affects younger males.
• Ankle fusion is a well-established treatment that can improve pain but does so at a loss of motion of the ankle. It doesn’t...
