“…27,31 Comparing functional outcomes between various TAR designs is hampered because the minimally important change has been shown to vary substantially for PROM subdomains. 13,15,18,29,33,41,42 The limitations of this study were those to be expected from a consecutive case series, with the limited percentage of available, fully completed PROMs at final follow-up being the most obvious one. Therefore, our functional outcome must be interpreted with care.…”

“…During the last decades, total ankle replacement (TAR) has shown to be a rapidly developing field that recently has introduced its fourth-generation models. The implant design, 15 surgical technique, 1,3,6,8,23,42 and patient selection 38 have undergone a remarkable evolution, contributing to its popularity 29 because of the improvement in patient quality of life. 13 However, with prostheses entering and leaving the market quickly, sometimes owing to higher than expected revision rates, or due to industry-driven factors, obtaining long-term follow-up is often hindered or absent.…”

Background: The ceramic coated implant (CCI) Evolution was a third-generation implant design used in approximately 2000 total ankle replacements (TARs) between 2003 and 2016. Because this implant was abandoned, long-term follow-up studies are lacking. Methods: All patients undergoing TAR using a CCI prosthesis between 2004 and 2012 were included for analysis. Preoperatively the tibiotalar alignment was measured, and postoperatively the patients were followed up clinically, with radiographs and by questionnaire. The primary outcome was implant survival at 10 years of follow-up. Implant survival was also compared for (1) inflammatory joint disease vs noninflammatory joint disease and (2) preoperative tibiotalar neutral vs varus or valgus alignment. The secondary outcomes were complications, reoperations, and function (assessed by patient-reported outcome measures). Results: Two hundred fifty-four TARs were performed in 237 patients. Two hundred twelve additional procedures were performed to achieve stable ankles. At 10-year follow-up, the survival was 67.5%, with an average time to revision of 4.5 years. The 10-year survival of the inflammatory joint disease group was 76.8% and of the noninflammatory joint group 63.1% ( P = .44). In 248 TARs, the preoperative tibiotalar alignment was measured; (62% neutral, 25% varus, and 13% valgus), these showed 10-year survival rates of 74.7%, 48.2%, and 68.9% respectively ( P = .07). The complication rate was 54%; 37% of patients underwent reoperation. At a mean of 8.5 years, postoperative satisfaction scored an average of 7.0 (SD 2.26) on a 0- to 10-point numeric rating scale. The mean Foot and Ankle Ability Measure sports subscore was 24.7, the mean Foot and Ankle Outcome Score (FAOS) sports subscore was 42.8, and the mean 36-Item Short Form Health Survey score was 40.0. Regarding daily activities, the mean FAOS was 81.0. Conclusion: This is currently the sole study reporting the long-term results of the CCI prosthesis. The survival and functional outcomes were inferior to other third-generation mobile-bearing ankle implants.

“…Among other promising innovations adapted from other orthopedic subspecialties are 3D printing, biologics. The recent use of 3D printing in orthopedics has been the generation of knee patient-specific implants (PSI), that are now available for ankle arthroplasty [36]. In foot and ankle surgery, 3D printing can be used for printing customized talus implants when the total collapse does not allow to perform cuts for a standard total ankle arthroplasty.…”
