| Popis: | Category: Ankle Arthritis; Ankle Introduction/Purpose: Total ankle arthroplasty (TAA) is a common procedure to treat end stage ankle osteoarthritis. Despite recent increase in popularity, there is limited literature assessing clinical and patient-reported outcomes (PROs) in TAA procedures using 5 current generation implants. These measures are an important tool for physicians to better assess patient performance in daily activities. The purpose of this study is to characterize both PROs and clinical outcomes in primary and revision TAA surgeries using current generation prostheses performed by non-design surgeons at a single institution. Methods: Our institution maintains a prospective outcomes registry for patients undergoing TAA at our institution. Patient demographics, relevant case information, PROs and complications are collected. Collected PROs include PROMIS Physical Function (PF), Pain Interference (PI), Depression, Global Physical Health (GPH), Global Mental Health (GMH), and Foot and Ankle SANE. Records are categorized as a primary TAA, or revision involving either a polyethylene only exchange or complete hardware removal and replacement. Differences between groups were determined non-parametrically using Mann-Whitney U tests. In all statistical tests, a p value of less than 0.05 was considered significant. Results: A total of 259 patients were included for analysis; 223 primary and 36 partial or full revision. Average length of stay was 1.6 ± 1 days. There were 18 reoperations (6.95%), with no implant failures within 1 year. Five patients underwent implant revision at an average of 2.5 years. Of these, one was related to delayed infection at year 3, two due to hardware failure in year 2, and 2 polyethylene exchanges in years 2 and 5. All physical health PRO measures showed significant improvements post-operatively (p < 0.0001). Patients reported significant reductions in pain following TAA at 3-months (Figure 1a), and significant improvement of physical function after 6-months (Figure 1b). There were no significant changes in Depression or GMH (Figure 1d). Conclusion: Total ankle arthroplasty is a safe and effective procedure for end-stage ankle arthritis. Patients experience improvement in all physical health PRO metrics at all post-operative time points after 3 months. Complication and early failure rates are lower than that reported in the literature. Long term outcomes and implant longevity will be tracked using the CU Total Ankle Registry. Total ankle arthroplasty improves quality of life in patients suffering from ankle osteoarthritis. Further follow-up and patient enrollment in the CU Total Ankle Registry will help us to identify risk factors for complications and define implant lifespan. |
