Prospective Controlled Trial of STAR Total Ankle Replacement versus Ankle Fusion: Initial Results
Background : Mobile-bearing ankle replacements have become popular outside of the United States over the past two decades . The goal of the present study was to perform a prospect i ve evaluation of the safety and efficacy of a mobile-bearing prosthesis to treat end stage ankle arthritis . We report the results of three separate cohorts of patients : a group of Sc and anavian Total Ankle Replacement ( STAR ) patients and a control group of ankle fusion patients ( the Pivotal Study Groups ) and another group of STAR total ankle patients ( Continued Access Group ) whose surgery was performed following the completion of enrollment in the Pivotal Study . Material s and Methods : The Pivotal Study design was a non-inferiority study using ankle fusion as the control . A non-r and omized multi-centered design with concurrent fusion controls was used . We report the initial perioperative findings up to 24 months following surgery . For an individual patient to be considered an overall success , all of the following criteria needed to be met : a ) a 40-point improvement in total Buechel-Pappas ankle score , b ) no device failures , revisions , or removals , c ) radiographic success , and d ) no major complications . In the Pivotal Study ( 9/00 to 12/01 ) , 158 ankle replacement and 66 arthrodesis procedures were performed ; in the Continued Access Study ( 4/02 to 10/06 ) , 448 ankle replacements were performed , of which 416 were at minimum 24 months post-surgery at time of the data base closure . Results : Major complications and need for secondary surgical intervention were more common in the Pivotal Study arthroplasty group than the Pivotal Study ankle fusion group . In the Continued Access Group , secondary procedures performed on these arthroplasty patients decreased by half when compared with the Pivotal Arthroplasty Group . When the Pivotal Groups were compared , treatment efficacy was higher for the ankle replacement group due to improvement in functional scores . Pain relief was equivalent between fusion and replacement patients . The hypothesis of non-inferiority of ankle replacement was met for overall patient success . Conclusion : By 24 months , ankles treated with STAR ankle replacement ( in both the Pivotal and Continued Access Groups ) had better function and equivalent pain relief as ankles treated with fusion . Level of Evidence : II , Prospect i ve Controlled Comparative Surgical
