Outcomes of Total Ankle Replacement.

Total ankle replacement (TAR) is an effective operative treatment of end-stage ankle osteoarthritis (OA) in the appropriate patient, conferring improved kinematic function, decreased stress across adjacent joints, and offering equivalent pain relief in comparison to ankle arthrodesis (AA). It is important to consider patient age, weight, coronal tibiotalar deformity, joint line height, and adjacent joint OA to maximize clinical and patient outcomes. Both mobile-bearing and fixed-bearing implants have demonstrated favorable clinical outcomes, marked improvement in patient-reported outcomes, and good survivorship; however, implant survivorship decreases with longer term follow-up, necessitating constant improvement of primary and revision TAR options.

Creating a community advisory board for pediatric bladder health.

Introduction: Pediatric lower urinary tract symptoms (LUTS) are highly prevalent in neurologically healthy school-aged children. However, no evidence-based programs exist to prevent or treat LUTS in the community setting. To address this, we established the first community advisory board (CAB) that aims to identify individual and societal structures impacting pediatric bladder health in Northern California's Bay Area and co-design culturally relevant bladder health interventions. Methods: Probability and non-probability sampling methods were used to recruit community stakeholders to the CAB. Our final CAB comprised of two parents, two community health workers, one educator, one pediatric urology registered nurse, and one pediatrician. The CAB met quarterly during the 1-year study period. Results: Bi-directional feedback identified community-level barriers to bladder health, particularly in the school environment, and the need for tailored resources to teach children and families about healthy bladder behaviors. Discussion: The CAB co-designed school-based bladder health interventions, including bladder health posters, and provided feedback on three school-based research study proposals. The CAB will continue to guide and inform future community-engaged research efforts.

Lessons From Revision Total Ankle Replacement: Tibias Fail Earlier, and Taluses Fail Later (and Fail Again).

BACKGROUND: The literature on survivorship and outcomes after revision total ankle replacement (TAR) in the modern era is limited. This study aimed to describe the timing to revision and survivorship after revision TAR. We hypothesized that tibial-sided failures would occur earlier after the primary TAR, and secondary revisions after failure of revision TAR would occur more due to talar-sided failures than tibial-sided failures. METHODS: This is a single-institution retrospective study of TAR patients with minimum 2-year follow-up. Revision TARs (defined as exchange of tibial and/or talar components) for aseptic causes with any implant were included. Etiology of failure necessitating revision and ultimate outcomes after revision (survival of TAR revision, additional revision, conversion to fusion, and below-knee amputation [BKA]) were recorded. RESULTS: There were 46 revision TARs, with mean age of 60.6 (range: 31-77) years and mean 3.5 years' follow-up postrevision. Revisions for tibial failure occurred significantly earlier (n = 22, 1.3 ± 0.5 years after index procedure) than those for talar failure (n = 19, 2.3 ± 1.7 years after index procedure) or combined tibial-talar failure (n = 5, 3.4 ± 3.4 years after index procedure) (P = .015). Revisions for tibial-only failure had better survival (95.5%) than revisions for talar or combined tibial-talar failures: 26% of talar failures and 20% of combined tibial-talar failures underwent ≥1 revisions. Of the 6 additional revisions after failure of the talar component, 1 ultimately underwent BKA, 2 were converted to total talus replacement, 2 were revised to modular augmented talar components, and 1 was treated with explant and cement spacer for PJI after the revision. CONCLUSION: TAR tibial failures occurred earlier than talar failures or combined tibial-talar failures. Revisions for talar failures and combined tibial-talar failures were more likely to require additional revision or ultimately fail revision treatment. This is important given the consequences of talar implant subsidence, bone necrosis, loss of bone stock, and limited salvage options.

Effects of Travel Distance on Complications and Outcomes in Total Ankle Arthroplasty.

Owing to the last decade's increase in the number of total ankle arthroplasty (TAA) procedures performed annually, there is a concern that the disproportionate distribution of orthopaedic surgeons who regularly perform TAA may impact complications and/or patient satisfaction. This study examines patient-reported outcomes and complications in TAA patients who had to travel for surgery compared to those treated locally. This is a single-center retrospective review of 160 patients undergoing primary TAA between January 2016 and December 2018, with mean age 65 (range: 59-71) years, mean body mass index (BMI) 28.7 kg/m2, 69 (43.1%) females, and mean 1.5 (SD = 0.51) years follow-up. Patients were grouped by distance traveled (<50 miles [n = 89] versus >50 miles traveled [n = 71]). There were no significant differences in rate or type of postoperative complications between the <50 mile group (16.9%) and the >50 mile group (22.5%) (P = .277). Similarly, there were no significant difference in postoperative PROMIS scores between the groups (P = .858). Given uneven distribution of high-volume surgeons performing TAA, this is important for patients who are deciding where to have their TAA surgery and for surgeons on how to counsel patients regarding risks when traveling longer distances for TAA care.Levels of Evidence: Level III: Retrospective Cohort Study.
