Anesthesia and Operation Procedures

femoral artery, patellar dislocation
Anesthesia was induced before surgery. After anesthesia was performed, the experimental group received an ACB nerve block using 0.3% ropivacaine 30 mL (AstraZeneca AB, Sweden) under ultrasound guidance (GE, USA) by a senior anesthesia team. The level of the nerve block was the midpoint of the line between the anterior superior iliac spine and the knee joint (Figure “3‐in‐1” procedure surgery with recurrent patellar dislocation and adductor canal block under ultrasound‐guidance. ① Lateral patellofemoral ligament release. ② Lower‐inner transfer of the tibial tuberosity. ③ Reconstruction of the medial patellofemoral ligament. ④ The operational procedure of adductor canal block.
