Abstract

Purpose: To evaluate correlations between preoperative pain sensitivity and postoperative analgesic consumption together with pain perception shortly after arthroscopic partial meniscectomy in non-arthritic knees. Methods: Ninety-nine patients who underwent primary arthroscopic meniscectomy were prospectively divided into three postoperative treatment groups that were prescribed with betamethasone injection (at the end of surgery), oral celecoxib or rescue analgesia (control). Preoperative pain sensitivity was evaluated by pain sensitivity questionnaires (PSQ). Patients were followed for the first three postoperative weeks to evaluate knee injury and osteoarthritis outcome score (KOOS) pain scores and analgesics consumption. Statistical analysis included correlations among preoperative pain sensitivity, postoperative pain levels and analgesics consumption. A receiver operating characteristic curve was plotted to investigate the cutoff values of the PSQ score to predict insufficient postoperative pain reduction. Results: There were no differences at baseline among all study groups in age, sex, BMI, level of activity, comorbidities and surgical findings. At the final follow-up, KOOS pain scores improved in all groups (p < 0.001). Mean final KOOS pain scores were 76.1 ± 15.2 for the betamethasone group, 70.8 ± 12.6 for the celecoxib group and 78.7 ± 11.6 for the control group. No differences in scores were observed among groups (n.s.). In the control group, a negative correlation was observed between PSQ score and KOOS-pain scores at the end of the follow-up in addition to a positive correlation between PSQ score and rescue analgesia consumption at the first postoperative week. The optimal cutoff value for PSQ score to predict insufficient improvement in KOOS-pain subscale was 5.0 points. Conclusions: A cutoff value of pain sensitivity questionnaire score above 5.0 points was determined to identify patients with higher sensitivity to pain who underwent arthroscopic partial meniscectomy. These patients reported relatively increased pain and consumed more rescue analgesics postoperatively unless treated with a single intraoperative corticosteroids injection or oral non-steroidal anti-inflammatories. Therefore, surgeons can use pain sensitivity questionnaire score as a preoperative tool to identify patients with high sensitivity to pain and customize their postoperative analgesics protocol to better fit their pain levels. Level of evidence: II.
