Summary
Total ankle arthroplasty (TAA) shows similar outcomes regardless of patient age. Younger and older TAA patients experienced comparable reoperation, complication, and implant survivorship rates, suggesting age is not a primary limiting factor.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Total ankle arthroplasty (TAA) is increasingly popular due to technological advancements improving survivorship and reducing complications.
- Historically, TAA candidates were limited to older patients with low physical demands and minimal deformity.
- Current surgical trends involve expanding patient inclusion criteria for TAA.
Purpose of the Study:
- To systematically review and compare patient outcomes after TAA in individuals over and under 50 years of age.
- To analyze the impact of patient age on TAA success metrics.
Main Methods:
- A systematic literature review was conducted.
- 159 articles were screened, with 7 studies meeting inclusion criteria for synthesis.
- Outcomes were compared between younger (<50) and older (≥50) TAA patient groups.
Main Results:
- No statistically significant differences were found between age groups for reoperation rates (p = .412).
- No statistically significant differences were observed for complication rates (p = .955).
- Implant survivorship showed no significant difference between the younger and older cohorts (p = .155).
Conclusions:
- Current literature suggests TAA outcomes are comparable between younger and older adult patients.
- The study's statistical model was underpowered due to a limited number of included studies.
- Further research is warranted to definitively establish TAA outcomes across different age demographics.
