Age-specific total ankle arthroplasty utilization rates per 100,000 for Whites and Blacks. (A) Age-specific rates for Whites. Cochran Armitage test comparing total ankle arthroplasty (TAA) utilization in all years: age <50, P = 0.11; age 50 to 64, P <0.0001; age 65 to 79, P <0.0001; age ≥80, P <0.0001. (B) Age-specific rates for Blacks. Cochran Armitage test comparing TAA utilization in all years: age <50, P = 0.07; age 50 to 64, P = 0.053; age 65 to 79, P = 0.009; age ≥80, P = 0.0002.
