Short to Midterm Clinical and Radiographic Outcomes of the Salto Total Ankle Prosthesis

Abstract

Level IV, case series.

Early Clinical and Radiographic Outcomes of Intramedullary-Fixation Total Ankle Arthroplasty

“…Estimated survival rates of 96.6% at two years and 93.2% at three years for the entire cohort are comparable with early results of other modern total ankle arthroplasty systems 8,9,14 . However, the reoperation rates for arthrofibrosis (15%) and talar component subsidence (8%) indicate that these important postoperative complications require further investigation.…”

Incidence of Revision After Primary Implantation of the Salto® Mobile Version and Salto Talaris™ Total Ankle Prostheses: A Systematic Review

“…In contrast, data that excluded these individuals had an incidence of revision of 2.8% (19 of 692) for the Salto Ò mobile version and 2.0% (2 of 98) for the Salto TalarisÔ total ankle prosthesis (20,24,(31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46). This was an unexpected finding because a major criticism of the studies that have involved inventors, design team members, or disclosed consultants is that they, by definition, represent a special interest group with much greater experience in using the particular implant design than the average surgeon.…”

“…Five studies involving 212 Salto TalarisÔ total ankle prostheses, with a weighted mean follow-up period of 34.9 months, were included (Table) (24,(42)(43)(44)(45)(46). Overlapping patients were evident for 1 data set involving disclosed consultants (43,44), and the data were abstracted as noted.…”

“…The potential for a learning curve effect could also exist because the implantation of total ankle replacement systems in the United States has evolved from limited use in the late 1990s to commonplace at present (86,87). For instance, the Salto Ò mobile version prosthesis data included this learning curve (20,24,(31)(32)(33)(34)36); however, the Salto TalarisÔ Total Ankle Prostheses data included data from surgeons experienced with the implantation of total ankle replacement systems in general (24,(42)(43)(44)(45)(46). However, the true effect, if any, a potential learning curve has on the incidence of revision for the Salto Ò mobile version and Salto TalarisÔ total ankle prostheses remains a matter for conjecture.…”

“…A total of 8 studies involving 1,209 Salto Ò mobile version prostheses, with a weighted mean follow-up period of 55.2 months (20,24,(31)(32)(33)35,36,(38)(39)(40)(41), and 5 studies involving 212 Salto TalarisÔ total ankle prostheses, with a weighted mean follow-up period of 34.9-months (24,(42)(43)(44)(45)(46), could be identified that met the inclusion criteria.…”
