Temporal Trends in Primary Total Hip and Knee Arthroplasty Preoperative PROMs from 2013-2021

Background: Patient reported outcome measures (PROMs) are utilized in total joint arthroplasty (TJA) to objectively evaluate patient function and track progress over time. Limited data exists on temporal trends of preoperative PROMs any specific effect COVID-19 functional status. The objective this study was identify changes time, determine the influence prior TJA.
 Methods: All patients undergoing unilateral primary hip (THA) or knee (TKA) by a single surgeon from 2013-2021 were retrospectively reviewed. Joint-specific relevant covariates compiled evaluated. Time series, univariate, multivariate analyses performed predictors PROMs.
 Results: After exclusions, 1,105 THAs 1,909 TKAs available for analysis. Preoperative activity level steadily increased 2015 2021 THA patients. For TKA patients, similarly 2019, however, decrease occurred 2020. No time series differences observed HOOS JR Knee Society “knee normal” scores.

 Conclusion: This demonstrated detrimental effects status, particularly Providers should consider surgical delays how changing These include rising levels TJA overall worsening during COVID era.
