Total knee arthroplasty (TKA) considered to be one of the most common orthopedic surgical procedures performed worldwide.
Anesthesia techniques had been developed as part of the development of the TKA surgical techniques over the past decades.
Regional anesthesia started to take the upper hand as the dominant form of anesthesia from the general anesthesia which was
considered as the standard practice in the past. It had been shown in many studies the probability of reducing intra-operative blood
loss, length of hospital stays, patient outcomes and mortality rates when regional anesthesia was used instead of general anesthesia.
