Multimodal analgesia (MMA) has been endorsed to improve postoperative analgesia and functional activity after surgery, and integrating regional analgesia to reduce the consumption of opioid has also been used in postoperative pain management. The investigator try to find a better combination of MMA for postoperative analgesia and functional recovery for patients receiving TKA in Taiwan, therefore the effect of single-injection and continuous infusion of peripheral nerve block is compared in patient undergoing unilateral TKA. The investigators hypothesize that continuous adductor canal infusion is as effective as single-injection adductor canal block for postoperative pain relief under intravenous PCA after TKA surgery. Based on that, the investigators conduct this prospective, randomized controlled trial to examine our hypothesis.
The study compares the effect of two multimodal analgesia protocols, the one integrating IVPCA morphine with single-injection adductor canal block and the other integrating continuous adductor canal infusion with timely administered intravenous tenoxicam, on postoperative analgesia and functional activity after TKA. To assess the outcome of both modalities, The investigators can have more comparative result of pain score and other functional parameters like range of motion of knee joint and muscle strength. Based on that, the investigators try to find a better multimodal analgesic approach for postoperative analgesia and functional recovery for patients receiving TKA in Taiwan. The investigators hypothesize that multimodal analgesia using continuous adductor canal infusion and intravenous tenoxicam are as effective as another modality using IVPCA and single-injection adductor canal block for postoperative pain relief after TKA surgery. However, continuous adductor canal infusion integrated with intravenous tenoxicam might reduce the occurrence of opioid-related side effect and enhance the functional recovery. Based on that, the investigators conduct this prospective, randomized controlled trial to examine our hypothesis.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Single-injection ACB combined with IV-PCA morphine | Active Comparator | Allocation of which participant is to receive single-injection adductor canal block combined with intravenous morphine patient-controlled analgesia (IV-morphine PCA) is determined by randomization, using a computer-generated random sequence and opaque sealed envelopes. After completion of the TKA surgery and surgical suturing, adductor canal block will be performed by an anesthesiologist. Under ultrasound guidance, the femoral artery and the saphenous nerve are identified in the middle one-third of the thigh, deep to the sartorious muscle in the adductor canal. The sartorious and adductor muscles form the roof and the floor of the canal, respectively. Following skin infiltration, 20 mL of 0.25% bupivacaine with 1:400000 epinephrine is injected through a 3-inch, 23-gauge, short bevel block needle. Finally, the IV-morphine PCA will be connected to the intravenous catheter of the patient for postoperative pain management. |

| Continuous adductor canal infusion combined with intravenous NSAID | Active Comparator | Allocation of which participant is to receive continuous adductor canal infusion in combination with intermittent intravenous non-steroidal anti-inflammatory drug (NSAID) is determined by randomization, using a computer-generated random sequence and opaque sealed envelopes. After completion of the TKA surgery and surgical suturing, a peripheral nerve catheter will be implanted into adductor canal by an anesthesiologist. Under ultrasound guidance, the femoral artery and the saphenous nerve are identified in the middle one-third of the thigh, deep to the sartorious muscle in the adductor canal. The sartorious and adductor muscles form the roof and the floor of the canal, respectively. Following the peripheral nerve catheter is implanted, 20 mL of 0.25% bupivacaine with 1:400000 epinephrine is injected through the catheter. Intravenous tenoxicam 20 mg for a total amount of 3 doses at 24-hour interval after surgery will be added in the postoperative pain management. |

A two-arm parallel assignment involves two groups of participants receiving multimodal analgesia after unilateral total knee arthroplasty. One group receives a single-injection adductor canal block combined with intravenous morphine patient-controlled analgesia, and the other group receives continuous adductor canal infusion in combination with intermittent intravenous non-steroidal anti-inflammatory drug.
