Palanisami DR, Reddy DA, Huggi V, et al. - Researchers investigated how preoperative pain sensitivity is associated with postoperative pain and analgesic requirements for patients undergoing primary total knee arthroplasty. Using a digital algometer, preoperative pain sensitivity was assessed in 178 consecutive patients undergoing primary total knee arthroplasty between December 2018 and April 2019. Relative to males, females had lower mean algometry values. Further, there was correlation of higher Depression Anxiety Stress Scale with lower algometry values. Observations revealed correlation of low algometer score with higher postoperative VAS score, increased analgesic requirement, and opioid utilization, delay in achieving an optimum range of movements and independent ambulation. Findings thereby suggest predictive value of preoperative assessment of pain sensitivity for postoperative analgesic requirements and recovery. They emphasize providing preoperative counseling and also a better titration of analgesics perioperatively and prolonged physiotherapy to patients with a lower pain threshold.
