ABSTRACT

Introduction: Total knee arthroplasty is associated with an intense postoperative pain. A number of techniques are being used to ease it. Objective: To compare the effectiveness and safety of three analgesic techniques to control post-surgical knee total arhroplasty pain. Methods: A double-blinded randomized clinical trial was conducted with three groups of fifteen patients each. Group A received intravenous analgesia; group B, epidural analgesia and group C, regional blockade. The intensity of pain was measured when the patient was motionless and when doing active movements at 12 and 24 hours; also, the adverse effects were registered. The statistical analysis included mean comparisons and Student T test. Results: Mean of age was 49.8 years, 57.8% were women. Group A, AVS 12 hours 1.5, active movement 2.6, 24 hours 1.8 and 3. Group B, 1.4 motionless, 1.9 when moving; at 24 hours, 1.8 motionless and 2.4 when moving. Group 3 AVS, motionless 0.1 and when moving 1.9; at 24-hour, motionless 0.2 and 3.0 when moving. There were not statistically significant differences among groups (p›0.05). Adverse effects: group A reported 13.3%; group B 6.7% and group C did not report adverse effects (p‹ 0.001). Conclusion: These three techniques are effective and safe to control postoperative pain after total knee arthroplasty.
