Early perioperative quality of recovery after hip and knee arthroplasty: a retrospective comparative cohort study.

Abstract

Increasing our knowledge about postoperative global Quality-Of-Recovery (QoR) after THA and TKA is important to improve perioperative medicine, in particular for preoperative patient information and benchmarking of postoperative patient status. This study is a single centre, retrospective cohort study of prospectively collected data, conducted in Strasbourg University Hospital, Strasbourg, France. The main outcome was the modified French version of the QoR-15 (mQoR-15F) score monitored preoperatively, at postoperative day one, three, 14 and 28. We questioned the hypothesis: would THA and TKA recovery patterns differ and would postoperative health status eventually overreach the preoperative reference? The mQoR-15F was statistically higher in the THA group compared to the TKA group in POD 1 and 28 (112 ± 17 vs. 107 ± 17; p < 0.01 and 131 ± 12 vs. 127 ± 15; p = 0.02, respectively). The mean postoperative time delay to reach preoperative mQoR-15F was seven and 16days for THA and TKA patients, respectively. Early postoperative health status after THA and TKA differs significantly; TKA being associated with a larger early decrease of global health status compared to THA. Both THA and TKA groups global health status overreached preoperative levels after one and twoweeks postoperatively. These surgery-specific recovery profiles may favor improved patient information to steer advised operative decision and set specific recovery goals as part of enhanced recovery pathways.
