Details and patient eligibility

About

The objective of this trial is to compare the efficacy of three different nerve blocks as an analgesic option after total knee arthroplasty (TKA), based on muscle strength, mobilization and pain.

The Adductor Canal Block has been proposed as an equally effective technique to the Femoral Nerve Block in terms of pain control after a TKA, with the benefit of preserving muscle function. We hypothesize that a block performed at the apex of the femoral triangle would best balance analgesia with quadriceps function.
