“…Age, mean follow-up, and body mass index (BMI) were not TARs were performed using a standard operative technique for each respective implant. 1,6,10,23 At the time of arthroplasty, any additional procedures required to achieve a balanced prosthesis and plantigrade foot, including osteotomy, arthrodesis, tendon transfer, or heel cord lengthening, were performed as deemed necessary by the operating surgeon. All patients were evaluated preoperatively at 3 weeks, 6 weeks, and 3 months postoperatively; clinical outcome assessments were made at 6 months and 1 year postoperatively, and annually thereafter.…”

Background: Ipsilateral hindfoot arthrodesis in combination with total ankle replacement (TAR) may diminish functional outcome and prosthesis survivorship compared to isolated TAR. We compared the outcome of isolated TAR to outcomes of TAR with ipsilateral hindfoot arthrodesis. Methods: In a consecutive series of 404 primary TARs in 396 patients, 70 patients (17.3%) had a hindfoot fusion before, after, or at the time of TAR; the majority had either an isolated subtalar arthrodesis (n = 43, 62%) or triple arthrodesis (n = 15, 21%). The remaining 334 isolated TARs served as the control group. Mean patient follow-up was 3.2 years (range, 24-72 months). Results: The SF-36 total, AOFAS Hindfoot-Ankle pain subscale, Foot and Ankle Disability Index, and Short Musculoskeletal Function Assessment scores were significantly improved from preoperative measures, with no significant differences between the hindfoot arthrodesis and control groups. The AOFAS Hindfoot-Ankle total, function, and alignment scores were significantly improved for both groups, albeit the control group demonstrated significantly higher scores in all 3 scales. Furthermore, the control group demonstrated a significantly greater improvement in VAS pain score compared to the hindfoot arthrodesis group. Walking speed, sit-to-stand time, and 4-square step test time were significantly improved for both groups at each postoperative time point; however, the hindfoot arthrodesis group completed these tests significantly slower than the control group. There was no significant difference in terms of talar component subsidence between the fusion (2.6 mm) and control groups (2.0 mm). The failure rate in the hindfoot fusion group (10.0%) was significantly higher than that in the control group (2.4%; p < 0.05). Conclusion: To our knowledge, this study represents the first series evaluating the clinical outcome of TARs performed with and without hindfoot fusion using implants available in the United States. At follow-up of 3.2 years, TAR performed with ipsilateral hindfoot arthrodesis resulted in significant improvements in pain and functional outcome; in contrast to prior studies, however, overall outcome was inferior to that of isolated TAR. Level of Evidence: Level II, prospective comparative series.

“…The failures in early studies usually occurred with cemented implants. In general, uncemented prostheses have been associated with better results than cemented ones (Saltzman 1999, Easley et al 2002, and uncemented types are now predominant.…”

257 ankle arthroplasties performed in Norway between 1994 and 2005

Background and purpose There have been few reports on the long-term outcome of ankle replacements. The Norwegian Arthroplasty Register has been registering ankle replacements since 1994, but no analysis of these data has been published to date. Here we report data on the use of total ankle replacements and the revision rate in the Norwegian population over a 12-year period.Methods We used the Norwegian Arthroplasty Register to find ankle arthroplasties performed between 1994 and 2005. Patient demographics, diagnoses, brands of prosthesis, revisions, and time trends were investigated.Results There were 257 primary ankle replacements, 32 of which were cemented TPR prostheses and 212 of which were cementless STAR prostheses. The overall 5-year and 10-year survival was 89% and 76%, respectively. Prosthesis survival was the same for the cementless STAR prosthesis and the cemented TPR prosthesis. There was no significant influence of age, sex, type of prosthesis, diagnosis, or year of operation on the risk of revision. The incidence of ankle replacements due to osteoarthritis, but not due to inflammatory arthritis, increased over the years.Interpretation The revision rate was acceptable compared to other studies of ankle arthroplasties, but high compared to total knee and hip arthroplasties. The overall incidence of ankle replacements increased during the study period.

“…Der Langzeiterfolg von meniskalen Dreikomponenten-Prothesen hängt weiter von einer einwandfreien ligamentären Stabilität und Balance am OSG ab. Eine bei OSG-Instabilität implantierte Prothese kann zu erhöhten Scherkräften an der Grenzzone zwischen Knochen und Implantat, erhöhtem Polyethylen-Abrieb, Komponentenlockerung und chronischen Beschwerden führen [6,8].…”
