Brief Summary
This study aims to compare continuous femoral nerve block with adductor canal block after anterior cruciate ligament reconstruction arthroscopically，especially in the effect on quadriceps strength; and to evaluate which regional anesthesia is more ideal for the patients postoperatively.

Study Arms (2)
adductor canal block (ACB)
EXPERIMENTALWe performed an ultrasound survey at the medial part of the thigh，the needle is introduced in-plane and 2 to 3 mL of saline is used to ensure correct placement of the needle in the vicinity of the saphenous nerve in the adductor canal,the catheter is introduced and advanced 1 to 2 cm beyond the tip of the needle.The study medication is administered as an infusion of 0.2% ropivacaine at a rate of 5mL/h during the next 48 hours.
Femoral nerve block (FNB)
ACTIVE COMPARATORthe catheter is inserted in-plane with the probe parallel to the inguinal crease, to obtain a short-axis view of the nerve. The correct needle placement is confirmed by injecting 2 to 3 mL of saline to cause tissue expansion below the iliac fascia, lateral to the femoral artery, and in the vicinity of the femoral nerve. The catheter is introduced 1 to 2 cm beyond the tip of the needle，an infusion of 0.2% ropivacaine at a rate of 5mL/h is administered during the next 48 hours.
