The purpose of this study was to investigate the effect of bupivacaine liposomes on postoperative pain in TKA ( total knee replacement ) patients.The main questions answered are: 1. Is bupivacaine liposomes superior to bupivacaine in femoral triangle block or adductor block in terms of 72 hours opioid consumption after knee replacement 2. Which block method(Femoral triangle block or adductor block) combined with bupivacaine liposome was more effective in alleviating pain score and 72 hours opioid consumption after total knee surgery. investigators will investigate the effect of bupivacaine liposomes combined with bupivacaine and pure bupivacaine on pain after total knee arthroplasty using femoral triangle block or adductor block. Participants will: 1. Receive liposomal bupivacaine or bupivacaine as a regional anesthetic for femoral triangle block or adductor block under ultrasound guidance. 2. Undergo total knee replacement surgery under spinal anesthesia. 3. Follow-up within 72 hours after surgery , opioid consumption, NRS score, PCA（Patient controlled analgesia，PCA） data, first postoperative remedial analgesia time, quadriceps muscle strength and complications were recorded
