METHODS: All primary THAs and TKAs performed in 19 Dutch hospitals between January 2017 and December 2019 were included. The Hip disability and Osteoarthritis Outcome Score-Physical function Short form (HOOS-PS) and Knee injury and Osteoarthritis Outcome Score-Physical function Short form (KOOS-PS) were used to assess the physical function after THA and TKA, respectively. Adverse events included 1-year revision, 30-day readmission, 30-day complications, and long (i.e., > 75th percentile) length-of-stay (LOS). A clinically relevant improvement was defined as at least a 10-point decrease in HOOS-PS and 9 points in KOOS-PS scores. Associations between adverse events and clinically relevant HOOS-PS and KOOS-PS improvement were assessed using binary logistic regression models adjusted for patient characteristics and clustering of patients within hospitals.
RESULTS: There were 20,338 THA and 18,082 TKA procedures included. Adverse events mostly occurred more frequently in HOOS-PS and KOOS-PS non-respondents than in respondents. The THA patients experiencing revision, complications, or long LOS were less likely to experience clinically relevant HOOS-PS improvements (odds ratios of 0.11 [0.06 to 0.20], 0.44 [0.30 to 0.63], and 0.66 [0.50 to 0.88], respectively). The TKA patients experiencing revision or long LOS were less likely to experience clinically relevant KOOS-PS improvements (odds ratios of 0.26 [0.12 to 0.55] and 0.63 [0.50 to 0.80], respectively).
CONCLUSIONS: Clinically-relevant HOOS-PS and KOOS-PS improvements are likely overestimated, as non-respondents had higher adverse event rates which were associated with lower likelihood to achieve clinically-relevant HOOS-PS and KOOS-PS improvements.
