Abstract
Background: Postoperative pain after total knee arthroplasty (TKA) is known to
range from moderate (30% of patients) to severe (60% of patients). Inadequate
management for postoperative pain may induce various immobility related
complications, muscle weakness, and chronic pain. Therefore, post-TKA analgesia is
crucial, not only for patients’ satisfaction, but for improving surgical outcomes and
reducing complications. The present study aims to compare the effect of ultrasound
guided adductor canal block ACB (saphenous nerve block) versus incremental dose of
intravenous morphine after total knee arthroplasty surgery.
Results: The results of this study revealed no difference between group A and
group B as regards postoperative quadriceps muscle strength; maximal knee flexion,
total distance ambulated and postoperative vital data (heart rate per minute and
respiratory rate per minute). However, group A showed better postoperative pain
control, lower doses of intravenous morphine consumption and lower incidence of
nausea and vomiting.
Conclusion: Continuous adductor canal block (saphenous nerve block) is superior
to intravenous morphine in decreasing postoperative pain, decreasing total morphine
consumption and adverse effects as nausea and vomiting but both are equivalent in
preserving quadriceps muscle power
