Abstract
Objectives: This study aimed to apply the International Association for the Study of Pain (IASP) grading system for identifying nociplastic pain in knee osteoarthritis (KOA) awaiting total knee arthroplasty (TKA) and propose criteria to fine-tune decision-making. In addition, the study aimed to characterize a "probable" versus "no or possible" nociplastic pain mechanism using biopsychosocial variables and compare both groups in their 1-year post-TKA response.
Methods: A secondary analysis of baseline data of a longitudinal prospective study involving 197 patients with KOA awaiting total TKA in Belgium and the Netherlands was performed. Two approaches, one considering 4 and the other 3 pain locations (step 2 of the grading system), were presented. Linear mixed model analyses were performed to compare the probable and no or possible nociplastic pain mechanism groups for several preoperative biopsychosocial-related variables and 1-year postoperative pain. Also, a sensitivity analysis, comparing 3 pain mechanism groups, was performed.
Results: Thirty (15.22%-approach 4 pain locations) and 46 (23.35%-approach 3 pain locations) participants were categorized under probable nociplastic pain. Irrespective of the pain location approach or sensitivity analysis, the probable nociplastic pain group included more woman, was younger, exhibited worse results on various preoperative pain-related and psychological variables, and had more pain 1-year post-TKA compared with the other group.
Discussion: This study proposed additional criteria to fine-tune the grading system for nociplastic pain (except for discrete/regional/multifocal/widespread pain) and characterized a subgroup of patients with KOA with probable nociplastic pain. Future research is warranted for further validation.
期刊介绍:
The Clinical Journal of Pain explores all aspects of pain and its effective treatment, bringing readers the insights of leading anesthesiologists, surgeons, internists, neurologists, orthopedists, psychiatrists and psychologists, clinical pharmacologists, and rehabilitation medicine specialists. This peer-reviewed journal presents timely and thought-provoking articles on clinical dilemmas in pain management; valuable diagnostic procedures; promising new pharmacological, surgical, and other therapeutic modalities; psychosocial dimensions of pain; and ethical issues of concern to all medical professionals. The journal also publishes Special Topic issues on subjects of particular relevance to the practice of pain medicine.
