“…They were promptly detected and treated accordingly, and they all recovered well. No serious complications occurred in our cohort group, and this result is close to previous studies [ 13 – 15 , 24 ] . Among them, three patients with medial malleolus fractures all had osteoporosis, two were post-menopausal women, and one was a man with traumatic arthritis and had disuse osteoporosis due to long-term crutches.…”

“…Research by Rushing et al [ 15 ] showed that 7 years after INBONE-II prosthesis replacement, the prosthesis survival rate reached 93.7%, and the complication rate was 33.3%. The case series of Berlet et al [ 24 ] showed that the 2.4-year implant survival rate after INBONE-II prosthesis replacement was 95.0%, and the complication rate was 24.8%. Therefore, we believe that the short-term complication rate of TAR with INBONE-II prosthesis is relatively low, and the survival rate of the prosthesis is relatively high.…”

Background: Total ankle replacement (TAR) is a viable option for the treatment of end-stage ankle arthritis. In China, the INBONE-II implant is the only total ankle prosthesis approved since 2016. The purpose of this study is to report a large sample of findings for the TAR with INBONE-II prosthesis. Methods: A total of 64 patients with end-stage ankle arthritis, who underwent primary TAR using INBONE-II by the same surgeon from 2016 to 2019, at a single institution were included in this retrospective, single-center study. Clinical data, radiographic findings, survival rate, and complications were recorded and assessed pre-operatively and at the most recent follow-up. Results: A total of 64 patients were available for follow-up at least 2 years after surgery; the mean follow-up duration for clinical outcomes was 37.9 months (24–59 months), and for radiographic findings was 22.8 months (12–59 months). There were significant improvements ( P < 0.01) in the American Orthopedic Foot and Ankle Society hindfoot scale, the visual analog scale for pain, and the Short Form-36. There were statistically significant differences between pre-operative and post-operative comparisons of the talar tilt angle (TT) and the tibial lateral surface angle (TLS) in the radiographic findings (TT from 4.7 ± 4.3° to 1.3 ± 1.3°, TLS from 80.4 ± 7.7° to 87.4 ± 2.3°, P < 0.01). There was no statistically significant difference in improvement of the tibial anterior surface angle ( P = 0.14). Ten complications (all low grade) were recorded according to the Glazebrook classification system. The survivorship of the prosthesis was 100% (64/64). Conclusion: Patients who underwent TAR with INBONE-II prosthesis demonstrated significant improvements in all measures of pain and function as well as in radiographic findings. High survival and a low incidence of complications were observed in this study.

Background: Compared to more prevalent arthritic conditions, ankle arthritis is complicated by an earlier age of onset. Recently published data demonstrates excellent survivorship and complication rates in short-/midterm follow-up of younger patients who received a primary total ankle arthroplasty (TAA). Additionally, older TAA patients display comparable reported outcomes relative to hip/knee arthroplasty. However, there remains a paucity of literature surrounding the reported outcomes of younger patients undergoing TAA. Thus, our aim was to assess the reported outcomes of individuals aged <50 years receiving a primary TAA. Methods: A retrospective cohort analysis of adult patients <50 years who received a primary total ankle replacement was conducted. Patient demographics, diagnosis, treatment, and outcome characteristics were recorded from a chart review of 41 patients with at least 1 year of postoperative clinical follow-up. Postoperative reported outcomes were obtained via telephone interviews. Primary outcomes that were measured included emotional and physical health, activity limitation, ambulation, and global health. Measures used included the 36-Item Short Form Health Survey (SF-36), Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health, and Sickness Impact Profile Ambulation. The functional outcomes in our study sample were compared with age- and gender-matched norms from a general US population, and 95% CIs were calculated for each functional outcome mean. Student t test was used for continuous variables, and χ2 analysis was used for categorical variables. Results: Thirty-one of 41 eligible patients were reached for interview. The average age at surgery was 39.7 years. Clinical and radiographic follow-up was a mean of 51.6 months and 31.2 months following TAA, respectively. General health as measured with the SF-36 was not significantly different from age-/gender-matched norms. Eighty-seven percent of patients would choose to have a TAA again. Although 58% reported being limited in vigorous activities, 61% were able to ambulate frequently for long periods of time. On average, the patients did not report ongoing pain, and only 16% reported fatigue that hindered activities. Eighty-one percent reported returning to full employment and performing their duties without difficulty, and 84% reported they resumed all normal social activities. Primary implant survivorship was 93%. Conclusion: Despite a younger age and potentially increased demands, patients aged <50 years undergoing primary TAA are generally satisfied with their index procedure at a mean follow-up of nearly 5 years. Our findings of positive outcomes on their health and well-being may improve surgeon insight for TAA as an alternative treatment for younger individuals with end-stage ankle arthritis. Level of Evidence: Level IV, case series.

Objective Total ankle replacement (TAR) and ankle arthrodesis (AA) are two common surgical treatment options for end‐stage ankle osteoarthritis. However, few reports compare the outcomes of simultaneous TAR and contralateral AA for bilateral ankle osteoarthritis. The aim of this study was to assess changes in pain, joint range of movement (ROM), functional outcomes, patient satisfaction, and cost‐effectiveness following simultaneous TAR and contralateral AA. Methods A retrospective study was conducted on 12 patients with bilateral end‐stage ankle osteoarthritis who underwent simultaneous TAR and contralateral AA in our institution between May 2016 and August 2018, and who had a minimum of two‐year follow‐up data. Clinical and radiological follow‐up data for all patients were collected after 4 months, 1 year and 2 years. The results were assessed clinically on a visual analogue scale (VAS) and included ROM, American Orthopedic Foot and Ankle Society (AOFAS) ankle hindfoot score, and satisfaction questionnaire. The total hospital costs of patients were also recorded. Independent sample t tests were conducted to compare continuous variables between groups. Paired sample t ‐tests were conducted to compare changes from the preoperative to postoperative evaluations within each group. Results Both surgical groups presented with pain reduction ( P < 0.001) at the one‐year postoperative session, which was generally consistent until the two‐year follow‐up. There was a significant increase ( P < 0.001) in the mean AOFAS score postoperatively in both ankles. The functional outcomes at the one‐ and two‐year follow‐up were significantly better in patients in the TAR group than in those in the AA group ( P < 0.001). Joint ROM differences were observed between the two groups after surgery (decreased ankle ROM in arthrodesis, P < 0.001; increased ankle ROM in arthroplasty, P < 0.001). The mean satisfaction score was 2 (range, 1–4) for the TAR group and 3 (range, 1–5) for the AA group. A significant difference in the satisfaction score was observed between the two groups ( P = 0.036). Simultaneous TAR and contralateral AA was 34.1% less expensive than simultaneous bilateral TAR. No intraoperative complications were noted in either group. Wound healing occurred without problems within 2 weeks after surgery. No symptomatic deep venous thrombosis was found during follow‐up. Conclusion TAR had better patient‐perceived post‐operative function and preserves more anatomic sagittal plane motion compared to ankles undergoing AA. In addition, simultaneous TAR and contralateral AA are more cost‐effective than simultaneous bilateral TAR, with lower costs for the average patient.
