Differences in outcomes after total hip arthroplasty for osteoarthritis between patients with and without central sensitivity syndromes other than fibromyalgia

Abstract

We investigated the differences in outcomes after total hip arthroplasty (THA) for hip osteoarthritis (HOA) between patients with and without central sensitivity syndromes (CSSs) other than fibromyalgia (FM). After excluding two patients with FM, we compared the clinical data of 41 patients with CSSs and 132 patients without CSSs.

Clinical data included scores on the central sensitization inventory, visual analog scale for pain (VAS pain), and Japanese Orthopedic Association Hip Disease Evaluation Questionnaire (JHEQ). VAS pain was significantly higher at 3 and 6 months after THA in patients with CSSs than in those without CSSs (3 and 6 months, P < 0.001). Satisfaction, pain, and mental JHEQ scores were lower in patients with CSSs than in those without CSSs (satisfaction, P < 0.001; pain, P = 0.011; mental, P = 0.032).

Multiple regression analyses indicated that one and ≥ 2 CSS diagnoses significantly impacted the satisfaction score (one CSS, β = − 0.181, P = 0.019; ≥ 2 CSSs, β = − 0.175, P = 0.023). Two or more CSSs were the only factor influencing the pain score (β = − 0.175, P = 0.027). Pain in patients with CSSs reflects central sensitization, which may adversely affect post-operative outcomes. Surgeons should pay attention to patients with a history of CSSs diagnoses who undergo THA for HOA.

From what I can see, only one person with CFS was included in this study, so feel free to move this to a different subforum if that's better suited.

 

central sensitisation is still just an unproven theory it infuriates me that so called academics and researchers continually write as if this is a proven fact .

 

If one just regards ‘central sensitivity’ inventories as crude indicators of self reported general health, rather than privileged accesses to a presumed but unevidenced neurological state, is this yet another study showing the worse someone’s health is the worse their health is?
