The purpose of this study was to compare complication rates and PROs among patients with RA, primary OA, or posttraumatic arthritis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>This was a retrospective study of 1,071 primary TAAs performed at a single institution between March 2000 and October 2020. Minimum follow-up was 2 years. Patients were stratified by indication for TAA (OA, n = 372; posttraumatic arthritis, n = 642; RA, n = 57). Patient demographics, intraoperative variables, postoperative complications, and PRO measures were compared among the groups using univariable statistics. Cox regression was performed to assess the risk of implant failure. The overall cohort had a mean age of 63.4 years, 51.3% were male, and 94.8% were White. The mean duration of follow-up (and standard deviation) was 5.7 \u00b1 3.1 years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Compared with the OA and posttraumatic arthritis groups, the RA cohort had the lowest mean age (p &lt; 0.001), lowest percentage of males (p &lt; 0.001), and highest American Society of Anesthesiologists (ASA) score (p &lt; 0.001). Univariable analysis showed no significant difference in the infection rate among the groups (p = 1.0). The RA cohort had the highest rate of heterotopic ossification postoperatively (2 of 57, 3.5%; p &lt; 0.040). Cox regression analysis showed no increased risk of implant failure for the RA cohort (p = 0.08 versus the OA cohort, 0.14 versus the posttraumatic arthritis cohort). For the Short Musculoskeletal Function Assessment (SMFA), Short Form (SF)-36, Foot and Ankle Outcome Score (FAOS)-symptoms subscale, and FAOS-activities of daily living subscale, the RA group reported significantly worse scores in the postoperative period (p &lt; 0.001).
