Analysis of Total Ankle Arthroplasty Survival in the United States Using Multiple State Databases

Abstract

Therapeutic, Level IV: Observational study.

Patient Risk Factors Do Not Impact 90-Day Readmission and Emergency Department Visitation After Total Ankle Arthroplasty

“…Of these readmissions, TAA-related readmissions totaled 3.5% of patients while 4.4% had a readmission that would count toward the bundle. Although LaMothe et al and Zhou et al determined that higher Charlson-Deyo comorbidity index and increased length of hospital stay were associated with 90-day readmission, neither of these factors were significantly associated with any of our study outcomes 6,7 . The current study further analyzed specific comorbidities and determined that none of the Elixhauser and Charlson-Deyo comorbidities were significantly associated with the outcomes of all-cause 90-day post-discharge readmission, TAA-related 90-day post-discharge readmission and ED visitation, or CJR-included readmissions in univariate or multivariable analysis.…”

“…Zhou et al reported a 30-day readmission rate of 2.7% that was associated with male sex, history of community-acquired pneumonia, and increased comorbidity burden 6 . Additionally, LaMothe et al reported a TAA 90-day readmission rate of 6.9% that was associated with increased length of stay following the index procedure and elevated Charlson-Deyo comorbidity index 7 . However, the specific risk factors contributing to readmission were not reported in these studies.…”

Midterm Outcomes of a Fixed-Bearing Total Ankle Arthroplasty With Deformity Analysis

“…21 Over the last decade, total ankle arthroplasty (TAA) has become increasingly popular as a means of alleviating the pain and functional deficits associated with arthritis of the ankle. 16…”

Total Ankle Arthroplasty: Long-term Survival and Factors that Influence it

“…Different TAA designs: 5, 10 and 15 year survivals Table 1 summarizes the 5, 10 and 15 year survivals of different existing TAA designs . The reported 5-year survival rate in United Sytes was 90.1% [40] . Kamrad et al found that revision TAA has a 10year survival of 55%, which is lower than the 10-year survival of 74% for primary TAA published from the same registry [41] .…”

“…It has ben observed that patients with rheumatoid arthritis or who were readmitted within 90 days of TAA had significantly augmented risk of failure. Risk factors for readmission were Charlson-Deyo Score ≥ 2 and increased length of stay during TAA [40] .…”
