Background and Aims Knee arthroplasty is one of the most effective surgeries in terms of efficiency in the treatment of gonarthrosis or rheumatoid arthritis and one of the most frequent orthopedic surgeries. The infiltration of local anesthetic around the femoral nerve has been, for years, the fundamental pillar of regional anesthesia in knee surgery. The two most frequent methods to treat this nerve are the infiltration of local anesthetic in a single puncture or in the form of continuous blockade with a catheter. Carry out a comparison to contrast the analgesic capacity of both forms of femoral block, assessing if there is an advantage of between them
Methods This project consists of a retrospective observational study based on data collected in the Acute Pain in routine clinical practice. The patients were divided according to whether they received a single puncture femoral block (34 cases) or a continuous femoral catheter (69 cases) and the QoR15 score on the first day after the surgery.
Results The comparison of the results of the QoR15 in patients with femoral block in a single puncture versus femoral block shows statistically significant differences between the groups to be studied, with a p=0012. Therefore, with the data from our sample, the patients presented a better ranking on the QoR15 scale.
Conclusions Femoral nerve block continues to be a fundamental pillar in the treatment of pain in knee arthroplasty surgery. Single puncture femoral block could be superior in analgesic control when compared to continuous infusion.
