ABSTRACT

Objective:

To evaluate the relationship between preoperative widespread pain and chronic post-surgical pain (CPSP) following total knee arthroplasty (TKA) in the patients with knee osteoarthritis.

Methods:

Two hundred American Society of Anesthesiologists physical status Ⅰ-Ⅲ patients with knee osteoarthritis, aged 40-70 yr, undergoing elective the first unilateral primary TKA under general anesthesia, were enrolled.The widespread pain index, visual analogue scale score, Hospital Anxiety and Depression Scale and Central Sensitization Inventory scores were recorded at 1 day before surgery.The patients were divided into CPSP-positive group and CPSP-negative group according to visual analogue scale score at 6 months after surgery.Risk factors for CPSP were analyzed by logistic regression.

Results:

The results of logistic regression analysis showed that increased preoperative widespread pain index score, Central Sensitization Inventory score and Hospital Anxiety and Depression Scale score and female were risk factors for CPSP after TKA.

Conclusions:

Preoperative widespread pain is a risk factor for CPSP following TKA in the patients with knee osteoarthritis.
