This study aimed to determine whether improvements in joint-specific outcomes following total hip arthroplasty (THA) or total knee arthroplasty (TKA) are associated with broader improvements in patient-perceived overall health, including physical health, mental health, and quality of life. Using propensity score-matched cohorts of 609 THA and 609 TKA patients, the authors found that improvements in HOOS-JR/KOOS-JR scores were moderately to strongly correlated with improvements in physical health and weakly but significantly correlated with mental health and quality of life at one year postoperatively. Importantly, these relationships were similar between THA and TKA patients, suggesting that recovery of joint function contributes meaningfully to patients’ overall health perceptions regardless of the joint replaced.
