Assessment for acute pain management in post-total knee replacement (TKR): a prospective cohort study in two Saudi Arabian medical centers

Background: Acute pain in post joint replacement surgeries is common, which makes the management of acute pain following joint replacement surgeries to be very important. Thus, this study was conducted to evaluate acute pain management of post TKR surgeries. Results: Patients with negative pain management index (PMI) scores were classified as receiving inadequate analgesic treatment for their pain. Zero PMI was the most frequent score among the others with 195 (80.6%). The rest were - 1 (11 (4.5%)), 1 (27 (11.2%)), and 2 (9 (3.7%)), respectively. Only 4.5% (11/242) patients have negative PMI score, which could be considered as inadequate pain management in which these patients received inadequate analgesic treatment. Conclusion: Acute pain management in post-TKR surgeries in both medical centers achieved an acceptable level, and majority of patients received an adequate analgesia in post-TKR surgeries.
