简要总结
In this study, we will compare Adductor canal block with femoral nerve block for postoperative analgesia, motor weakness of the quadriceps muscle and degree of knee flexion in patients undergoing primary bilateral total knee arthroplasty[TKA]. Only a few number of studies have compared the ACB approach with FNB approach in a clinical setting involving TKA patients. Since pain perception and pain threshold varies from individual to individual, a significant interpatient variability exists, which can lead to bias. In order to overcome this bias we will be using a method that would allow us to compare both these nerve blocks in the same individual, by enrolling patients undergoing the same surgical procedure in both the lower limbs, such as bilateral TKA.
We hypothesised that Adductor canal block [ACB] would provide analgesia non-inferior to femoral nerve block[FNB] as assessed by Visual analogue scale and ACB would be associated with less quadriceps motor weakness than FNB.
