Clinical Trial Summary

It has been well known that central sensitization (CS) is a risk factor for inferior outcomes following total knee arthroplasty (TKA). However, there are still insufficient studies on the relationship between CS and neuropathic pain (NP), and the effects of CS and NP on the patient-reported outcome measures (PROMs) of patients who underwent TKA. The purpose of this study was to investigate the relationship between CS and NP and whether CS and NP were associated with PROM in patients undergoing TKA.


Description:

A total of 312 patients who underwent primary TKA for end stage knee OA were enrolled. CS was defined as a patient with a score of 40 or higher using central sensitization inventory (CSI). NP was defined as a patient with a score of 12 or more using pain detect questionnaire (PDQ). PROMs were also evaluated based on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score preoperatively and at postoperative 1 year. The patients were divided into 4 groups, group 1 with CS and NP positive, group 2 with only CS positive, group 3 with only NP positive, and group 4 with CS and NP negative, and PROM was compared between the groups.

Outcome

Type Measure Description Time frame Safety issue
Primary Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score Western Ontario and McMaster University Arthritis Index (WOMAC) scale is a validated questionnarie for evaluation of patients who underwent knee operation. The questionnaire consists of 24 tiems, with five pain-related categories (score range 0-20), two stiffness categories (score range 0-8), and 17 physical functional categories (score range 0-68). All items were scored on a 5-point Likert scale (0 = none, 1 = slightly, 2 = moderate, 3 = serious, 4 = extreme). Total score range is 0-96. The lower the score, the better the result. 2 years after TKA
