“…Results from the acute pain trajectory model are strikingly similar to those obtained among patients undergoing total hip arthroplasty (Page et al., ), namely highlighting subgroups of patients with unchanging elevated or mild pain intensities as well as those with rapidly improving pain intensity. The literature is controversial regarding the association between acute post‐operative pain trajectories and CPSP outcomes (Althaus, Arranz Becker, & Neugebauer, ; Bonnet, Lavand'homme, France, Reding, & De Kock, ; Page et al., ). While acute post‐surgical pain, typically measured as a static variable, is a common risk factor for CPSP (Katz, ; Katz & Seltzer, ; Katz et al., ; Perkins & Kehlet, ; Schug & Bruce, ), the lack of such significant association in pain trajectory studies highlights the importance of examining the heterogeneity of pain responses acutely in the understanding and the prevention of CPSP.…”
