Palanisami DR, Reddy DA, Hugi V, et al. - This study was undertaken to compare preoperative pain sensitivity and postoperative pain and analgesic requirements for patients undergoing primary total knee arthroplasty (TKA). Researchers evaluated the pain sensitivity of 178 consecutive patients undergoing primary TKA preoperatively with a digital algometer between December 2018 and April 2019. They recorded postoperative visual analog scale (VAS) score, analgesic requirement, and physiotherapy milestones in all of these patients on day 0 to day 4. This study's findings demonstrate that preoperative evaluation of pain sensitivity prognosticates postoperative analgesic requirements and recovery. The data exhibited that individuals with a lower pain threshold should be counseled preoperatively and also receive a better titration of analgesics perioperatively and prolonged physiotherapy.
