Background: A continuous femoral nerve block is frequently used as an adjunct therapy after total knee arthroplasty (TKA). However, there is still debate on its benefits. Methods: In this prospective, randomized study, patients received a basic analgesic regimen of paracetamol and dicloflenac for the first 48 h postoperatively. In addition, the study group received a continuous femoral nerve block. A morphine patient-controlled analgesia pump was also available as a rescue analgesic to all the patients. Patients' numeric rating scores for pain, the amount of morphine consumed and its side effects during the first 48 h were recorded. Knee flexion angles achieved during the first week were registered. Three months postoperatively, patients completed Western Ontario and McMaster Universities Osteoarthritis Index and Knee Society Score. Results: The study group ( n=27) had less pain ( P=0.0016) during the first 48 h, was more satisfied with the analgesia ( P<0.001) and used less morphine ( P=0.007) compared with the control group ( n=26). Fewer patients were nauseated, vomited or were drowsy in the study group ( P=0.001). Also, the study group achieved better knee flexion in the first 6 days after surgery ( P=0.001), with more patients reaching 90° flexion than the control group. However, after 3 months, there were no significant functional differences between the groups. Conclusion: A continuous femoral nerve block leads to better analgesia, less morphine consumption and less morphine-related side effects after TKA. Early functional recovery is improved, resulting in more patients reaching 90° knee flexion after 6 days. However, after 3 months, no significant functional benefits were found.
