Description
[edit | edit source]
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 osteoarthritis ankle pathology. The majority of ankle osteoarthritis is secondary to trauma.[1]
Until relatively recently, ankle joint arthrodesis (fusion) was the gold standard of treatment, but this was not without its complications, e.g. non-union, osteoarthritis in the other mid/hind foot joints and stiffness and loss of proprioception[2]
Total ankle replacement was developed in the 1970's but initially was plagued with high long term failure rates. The older prosthesis loosened or malfunctioned and frequently needed to be removed[3]. In the late 70's Dr. Frank G. Alvine an orthopedic surgeon from Sioux Falls, SD developed the Agility Ankle which was the first FDA approved total ankle implant in use in the United States[4]. Since its introduction the Agility Ankle System has gone through several modifications. Currently the Agility Ankle System is the most widely used ankle prosthesis. With more than 20 years of experience it has the longest followup of any fixed bearing device[5].
On May 29, 2009 the medical news today announced the FDA approved the first mobile bearing device called the Scandinavian Total Ankle Replacement System (STAR). As a condition of FDA approval the company (Small Bone Innovations Inc.) must evaluate the safety and effectiveness of the device during the next eight years[6].
In a systematic review of the literature published in the Journal of Bone and Joint Surgery in 2007, the intermediate outcome of total ankle arthroplasty appears to be similiar to that of ankle arthrodesis however data was sparse[7]. In a study comparing reoperation rates following ankle arthrodesis and total ankle arthroplasty SooHoo, Zingmond and Ko confirmed that ankle replacement is associated with a higher risk of complications as compared with ankle fusion, but also has potential advantages in terms of a decreased risk of the patient requiring subtalar joint fusion[8]. In a seven to sixteen year follow up on the Agility Total Ankle Arthroplasty, Knecht, Estin, Callagham et al concluded that the relatively low rates of radiographic hindfoot arthritis and revision procedures at an average of nine years after the arthroplasty are encouraging[9].
Although interest in total ankle replacements is increasing, midterm clinical results to date are few and often have not been validated by independent pratitioners. In addition no level I or II studies have been published[10].
