Does Age Influence Patient Reported Outcomes in Unilateral Primary Total Hip and Knee Arthroplasty

Abstract Background Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are used to treat patients with end-stage arthritis. Previous studies have not demonstrated a consistent relationship between age and patient reported outcomes. The purpose of this study is to assess the impact of age on patient reported outcomes after unilateral primary THA or TKA. Methods A retrospective review of available data in affiliated institute’s Data Repository was performed. We identified 53,498 unilateral primary THA and TKA between April 2011-2017. Patients were divided by age into 3 categories: 70. WOMAC and EQ-5D Canada scores were obtained at pre-surgery, 3 and 12 months post-operatively. Results For TKA, younger patients had larger improvements in WOMAC scores at 3 and 12 months (p = 70 (all p For THA, younger patients had larger improvements in WOMAC at 3 months (p=0.03). When adjusted, patients 70, and higher EQ-5D scores compared to those 55-70 (all p Conclusion While a multitude of factors go in to quantifying successful THA or TKA, this study suggests that patient age should not be a deterrent when considering the impact of age on patient reported outcomes.
