This single-institution series of 40 elbows (mean age 59 years, mean follow-up 9 years) evaluated total elbow arthroplasty (TEA) for post-traumatic sequelae after proximal ulna or radius fractures or fracture-dislocations. When successful, TEA provided pain relief and functional restoration, but overall revision rate was 28% with common complications including neurologic events, aseptic loosening, and deep infection; 10-year implant survival free of revision or resection was 73%.

In propensity‑score matched cohorts of 609 total hip arthroplasty (THA) and 609 total knee arthroplasty (TKA) patients, changes in joint‑specific PROMs (HOOS JR/KOOS JR) from preoperative to one year postoperatively were moderately to strongly correlated with PROMIS‑10 physical health (THA r=0.63; TKA r=0.56) and weakly correlated with mental health and quality of life. The strength of these correlations did not differ significantly between THA and TKA, supporting joint‑specific PROMs as reflective of overall physical health improvements.

In a retrospective cohort of 12,950 first-time aseptic revision total knee arthroplasties (median follow-up 7.4 years) from the National Joint Registry, constraint level (unconstrained, posterior-stabilized [PS], condylar-constrained [CCK], hinge) was compared for implant survivorship. CCK constructs had the lowest unadjusted 10-year cumulative incidence of re-revision and, in adjusted analyses, unconstrained and PS implants showed higher re-revision risk than CCK until further implant-level adjustment (after which unconstrained and PS risks were similar to CCK), while hinged prostheses retained a higher re-revision risk; the authors conclude CCK use was associated with favourable implant survivorship across scenarios.
