Acute Postoperative Pain and Catastrophizing in Patients Undergoing Unicompartmental Knee Arthroplasty - A Prospective, Observational, Single-center, Cohort Study
In Brief
An observational study for Post Operative Pain. Completed, enrolled 146 participants across 1 site.
Detailed Summary
Advantages of unicompartmental knee arthroplasty (UKA) compared to total knee arthroplasty (TKA) include shorter hospital stays, faster recovery, fewer infections and readmission, and lower costs. It is well documented in TKA-surgery that high pain responders (HPR), evaluated using the Pain Catastrophizing Scale (PCS), have higher postoperative pain responses compared to low pain responders (LPR). These HPR-patients constitute a vulnerable high risk patient group and potentially benefit from targeted treatment. Currently, the distribution of HPR- and LPR-patients and their association with acute pain following UKA is not well investigated. The knowledge that this research project generates is essential to determine how studies with analgesia interventions should be designed. In the future this will contribute in targeting treatment for high risk patient groups to reduce pain and improve postoperative mobilization, and ultimately decrease length of hospital stay in patients undergoing UKA. By targeting treatment, a potential overtreatment is also avoided. The aim of this study is to investigate the prevalence of high- and low-pain responders, defined by a PCS score \> 20 and ≤ 20 respectively, as well as the acute postoperative course of pain for these groups after unicompartmental knee arthroplasty.
