Abstract:

Category: Ankle Arthritis Introduction/Purpose: Total ankle replacement (TAR) evolved over the last decades and has been shown to be an effective concept in the treatment of ankle osteoarthritis (OA). In three-component designs, the second interface between polyethylene insert (PI) and tibial component allows the PI to find its position according the individual physiological properties. This was believed to decrease shear forces within the ankle joint. However, it is not clarified to which extent such an additional degree of freedom may overload the ligamentous structures of the ankle joint ov

Abstract:

Category: Ankle Arthritis Introduction/Purpose: Total ankle replacement (TAR) was initially performed with first-generation cemented components. These constructs showed unacceptable revision and complication rates, in part due to the difficulty of obtaining a uniform cement mantle and the unique difficulties with TAR regarding the inability to dislocate the joint for exposure. Early concerns with polymethylmethacrylate (PMMA) in knees led to multiple studies evaluating fixation of total knee components by bone ingrowth using prospective randomized studies, registry data, and radiostereographic

Abstract:

Category: Ankle Arthritis Introduction/Purpose: A key for success in total ankle replacement (TAR) is a balanced ankle joint with a physiological loading of the implant, minimizing the wear of the polyethylene insert. Theoretically, in ankles with distal tibial deformities, this can be achieved with a correcting tibial resection cut. As an alternative, supramalleolar osteotomy (SMOT) can be used for balancing the ankle during TAR surgery.

Abstract:

Total ankle replacement (TAR) is the replacement of a damaged arthritic ankle joint with a prosthetic implant to eliminate the source of resultant pain and swelling. Historically, however, the ankle joint has been one of the most difficult joints to analyze and replicate for successful replacement due to its complex anatomy and multiplanar motion. Ankle fusion, the standard of care for end stage ankle arthritis, has excellent functional outcomes but results in loss of motion at the joint. TAR was first attempted in the 1970s and by the early 1990s, prosthesis designs more closely mirrored the

Abstract:

Abstract Total ankle replacement (TAR), also known as total ankle arthroplasty, has been used since the early 1970s, but, because of improvements in both techniques and materials, the procedure is used more frequently, and examiners are asked to rate permanent impairment resulting from TAR. The AMA Guides to the Evaluation of Permanent Impairment, (AMA Guides) is silent about rating ankle impairment following arthroplasty but does provide a two-step method to rate the results of total hip and knee replacements. Using tables in the AMA Guides, examiners can rate disability associated with TAR.

Abstract:

Avascular necrosis (AVN) of talus is a well-known complication following talar neck fracture that leads to osteoarthritis of the ankle joint. Tibiotalar fusion is the gold standard of treatment in end-stage ankle osteoarthritis with predictable good outcome. With the introduction of newer generation of total ankle replacement (TAR), it is gaining popularity as an alternative treatment in selected cases of ankle joint osteoarthritis secondary to AVN talus. We present here a case of ankle joint osteoarthritis secondary to AVN talus in a 30-year-old female in which a TAR was performed. We wish to

Category: Ankle, Ankle Arthritis Introduction/Purpose: Total ankle replacement (TAR) is becoming increasingly popular amongst patients with end-stage ankle arthritis. This is in part related to the advances in design, technology, and technique that have improved TAR longevity. The ideal candidate for a TAR is not fully clear. For a long time patients over age 50 years, body mass index (BMI) under 30 kg/m2, and with low functional demands represented selection criteria for many patients. However, these criteria were based off a very limited number of scientific studies on older TAR designs. The

Currently, no studies exist evaluating the epidemiological, pre-operative, and temporal trends between TTA and TAR.
