Biological therapy versus intra-articular analgesic pump for postoperative pain management in anterior cruciate ligament reconstruction

Abstract

Many studies have demonstrated the usefulness of PRP in reducing pain in the donor area of the patellar tendon used as a graft, having an anti-inflammatory effect and reducing postoperative pain. Currently, in the study on 'intra-articular local anesthesia of the knee', several techniques used for anesthesia and analgesia in arthroscopic surgery are determined. Objective: Determine the effectiveness of biological therapy versus intra-articular analgesic pump in the management of postoperative pain in ACLR. Method: Longitudinal and prospective field with experimental study design. Presented a sample of twenty-eight patients, with a diagnosis of ACL rupture, who attended the knee unit consultation and were subdivided into two groups of fourteen patients with application of random treatment, then the Lysholm functional scale and VAS were applied to verify the degree of postoperative pain after 24 hours and a week. Results: Regarding VAS, a decrease is evident in both groups that was corroborated through hypothesis tests of difference in means, where the p-values obtained were significant (p-value: 0.0177 and 0.0062). On the contrary, on the Lysholm scale there was an increase in the average value after the application of biological therapy and analgesic pump (p-value: 2.2E-08 and 1.3689E-08). Conclusion: The effectiveness of both methods was similar in the clinical evolution, however, the statistical differences were greater one week after the treatment was applied than in the first 24 hours.
