The primary objective of the study is to compare motor strength in knee extension between two groups of patients. One group receiving a proximal thigh block of the femoral nerve, and one receiving a distal thigh block of the saphenous nerve. The secondary objective is to compare the pain relief and functional outcomes in these two groups.
