Abstract:

Category: Ankle Arthritis Introduction/Purpose: It has been shown that total ankle replacement (TAR) is effective in reducing pain and maintaining function in posttraumatic ankle osteoarthritis (OA). Compared to ankle fusion, TAR restores hindfoot kinematics more physiological. However, the assumption that the maintenance of ankle motion has a protective effect on the subtalar joint is still a matter of debate. Only a scarce number of long-term studies exist to support this statement.The purpose of this study was (1) to evaluate to which extent the integrity of the subtalar joint can be preser

Abstract:

Background:An advantage of total ankle replacement (TAR) compared to ankle fusion is that by maintaining motion, the occurrence of hypermobility of adjacent joints may be prevented. This could affect the development of symptomatic subtalar joint osteoarthritis (OA). The aim of the study was to determine the incidence of subtalar joint fusion and the progression of subtalar joint OA following TAR.Methods:Secondary subtalar joint fusion rate was determined from a cohort of 941 patients receiving primary TAR between 2000 and 2016.

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

The influence of some simple design variations on the compressive load bearing capacity of tibial and talar prosthetic components in total ankle joint replacement were investigated in an attempt to suggest improvements to current prosthetic designs. Eighteen paired ankle joint preparations were fitted with three types of tibial components and two types of talar components. The tibial component with an intramedullary peg tolerated significantly higher loads before mechanical failure than the two other designs that were equal in load bearing capacity.

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

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.

However, both cost and time can be one of the constraints factors, particularly in the early stage of design or analysis.

The computational wear simulation has been widely used on the hip and knee but very less found in study related to wear analysis of the ankle.

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:

Background: Total ankle replacement (TAR) and ankle arthrodesis (AA) are usually performed for severe ankle arthritis. We compared postoperative foot segmental motion during gait in patients treated with TAR and AA. Methods: Gait analysis was performed in 17 and 7 patients undergoing TAR and AA, respectively. Subjects were evaluated using a 3-dimensional multisegmental foot model with 15 markers. Temporal gait parameters were calculated. The maximum and minimum values and the differences in hallux, forefoot, hindfoot, and arch in 3 planes (sagittal, coronal, transverse) were compared between t

Abstract:

Background: Persistent pain despite a total ankle replacement is not uncommon. A main source of pain may be an insufficiently balanced ankle. An alternative to the revision of the existing arthroplasty is the use of a corrective osteotomy of the distal tibia, above the stable implant. This strictly extraarticular procedure preserves the integrity of the replaced joint. The aim of this study was to review a series of patients in whom a corrective supramalleolar osteotomy was performed to realign a varus misaligned tibial component in total ankle replacement. We hypothesized that the supramalleo

Abstract:

Category: Ankle Arthritis Introduction/Purpose: Total ankle replacement (TAR) is common tool used by the foot and ankle specialist to treat end stage ankle arthritis. Current data about ankle motion following TAR is derived from gait analysis utilizing external markers. Utilizing Xray Reconstruction of Moving Morphology (XROMM), which combines 3-D mapping technology with biplanar fluoroscopy in vivo to visualize true skeletal motion, we can evaluate true motion of TAR implants. Current TAR replacement systems are either mobile bearing or fixed bearing. We hypothesized that subjects implanted w

Abstract:

Category: Ankle Arthritis Introduction/Purpose: Initial implant fixation is critical for long-term success of total ankle replacement (TAR). One important factor which contributes to implant stability is the quality of the surrounding bone. Previous studies characterized a decrease in bone density with increasing distance from the level of the joint in the tibia and talus in non-arthritic ankles. However, ankle arthritis affects bone density remains unclear. The objective of this study is to compare the bone density in patients with and without ankle arthritis as a function of resection level

Abstract:

Category: Ankle Arthritis Introduction/Purpose: A gait analysis of patients who underwent simultaneous total ankle replacement (TAR) and subtalar fusion allows to assess the ankle range of motion (ROM) with precision. In healthy subjects or in patients who underwent isolated TAR this is not possible because it is influenced by the subtalar ROM and it is not possible to analyse the two joints separately. Excluding the role of the subtalar joint, it is possible to analyse the consequences of different prosthetic designs and different surgical approaches on joint kinematics. The aim was to evalua

Abstract:

A congruent contact, unconstrained, multiaxial ankle replacement has been developed for use without cement. A talar onlay component with a trochlear surface and central fixation fin uses a cylindrical articulating axis that reproduces the lateral talar curvature. A tibial inlay component with a 7° anteriorly inclined short fixation stem uses a flat loading plate, recessed anatomically into the distal tibia to distribute tibial loads to the ankle joint. For both components, made of cast cobalt-chromium-molybdenum, a 275-μm pore-size, sintered-bead, porous coating is used to allow tissue ingrowt

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. To date, however, no data exist whether a SMOT in addition to TAR results in better outcome over time, and which are the additional risks with such extensive

Background: Total ankle replacement (TAR) is becoming a more common alternative to ankle arthrodesis for the improvement of pain and function in end-stage arthritis of the ankle. The effects of end-stage arthritis of the ankle are similar to those of end-stage hip arthritis. There is a paucity of literature on patient-reported outcome measures (PROMs) following TARs in comparison with total hip replacement (THR) or total knee replacement (TKR).
