Arthroscopic Knee Ligament Reconstruction Clinical Trial
This study aims to describe and to evaluate the effectiveness (success rate) of a supine ultrasound (US) guided single-puncture sciatic, obturator and femoral neve block technique (SOFT block) in knee surgery.
Under aseptic technique, all the patients will receive US-guided femoral, obturator and
sciatic nerve blocks using a single puncture point. All blocks will be performed by an
expert anesthetist. The femoral nerve will be blocked lateral to the femoral artery. The
obturator nerve will be blocked after it exits the obturator canal (deep to pectineus
muscle). While the sciatic nerve will be blocked deep (posterior) to the inferior border of
quadratus femoris muscle. The motor block of the femoral, obturator and sciatic nerves and
sensory block of the lateral femoral cutaneous nerve (LFCN) will be assessed before shifting
the patient to the operating room.
The performance time, patient discomfort, technique success rate, the associated successful
LFCN block and any complication will be recorded by the assistant. All patients were
assessed neurologically before discharge and during the physiotherapy visits for 3 weak
after surgery.
