Adductor Canal Block and Multimodal Local Infiltration Analgesia in Patients Receiving Total Knee Arthroplasty

Comparison of Analgesic Efficacy and Functional Improvement of Adductor Canal Block and Multimodal Local Infiltration Analgesia for Patients After Bilateral Total Knee Arthroplasty

Total knee arthroplasty (TKA) is associated with moderate to severe pain after operation. There are twenty thousand patients undertaking TKA annually in Taiwan, and the average length of hospital stay is about seven to ten days. In contrast, the length of hospital stay is only three to six days in some literatures. Adequate pain relief after surgery allows patients to mobilize earlier and easier and rehabilitate to reduce the length of hospital stay. By reducing hospital stay, we can reduce medical expenditure of national health insurance. In addition, effective analgesia can reduce the occurrence of chronic post-surgical pain which would compromise life quality and produce socioeconomic problems. This study tries to find a better solution for postoperative analgesia of TKA for patients in Taiwan. The present clinical study compares the effect of adductor canal block and local infiltration on postoperative analgesia and functional activity after TKA. To assess the outcome of both methods in the same patient, we can have more comparative result of pain score and functional parameters like range of motion of knee joint, time and ability to ambulate. Based on that, we try to find a better option for postoperative analgesia for patients receiving TKA in Taiwan.

Detailed Description

Total knee arthroplasty (TKA) is associated with moderate to severe pain after operation. There are twenty thousand patients undertaking TKA annually in Taiwan, and the average length of hospital stay is about seven to ten days. In contrast, the length of hospital stay is only three to six days in some literature. Some patients choose to receive bilateral TKA simultaneously to avoid repetitive surgery and anesthesia, and are supposed to suffer more than those receiving unilateral TKA. Adequate pain relief after surgery allows patients to mobilize earlier and easier and rehabilitate to reduce the length of hospital stay and postoperative complications. By reducing the length of in-hospital stay and post-operative complication, we can reduce medical expenditure of national health insurance. In addition, effective analgesia can reduce the occurrence of chronic post-surgical pain which would compromise life quality and produce socioeconomic problems. This study tries to find a better solution for postoperative analgesia of TKA for patients in Taiwan. The present clinical study compares the effect of adductor canal block and local infiltration on postoperative analgesia and functional activity after bilateral simultaneous TKA. To assess the outcome of both methods in the same patient, we can have more comparative result of pain score and functional parameters like range of motion of knee joint, muscle power in knee adduction/abduction movement, and time and ability to ambulate. Based on that, we try to find a better option for postoperative analgesia for patients receiving TKA in Taiwan.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Adductor canal block; Allocation of which limb is to receive adductor canal block 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.	Other: Pain scores (numerical rating scale at rest and motion); As the primary outcome of the present clinical study, pain scores will be assessed with numerical rating scale at both rest and motion on both knees.; Other: Secondary outcomes; Brief Pain Inventory (Short Form), WOMAC Osteoarthritis index, and Lower extremity functional scale will be used as the questionnaires for functional assessment. Rehabilitation physiotherapy will be assessed with knee range of motion (both active and maximal passive), muscle power at abduction and adduction, single leg stance test, six-minute walk test for assessment of the functional recovery of knee joints.
Experimental: Local infiltration; Allocation of the other limb to receive local infiltration is determined after randomization of the knee allocated for adductor canal block in the same patient. The chosen knee is infiltrated by the orthopedic surgeon intraoperatively with a 150-ml mixture of 150 mg bupivacaine, 10 mg morphine, 30 mg ketorolac, and 0.5 mg epinephrine. The posterior capsule is infiltrated before placement of the prosthesis, and the periarticular and superficial soft tissues are infiltrated after the prosthesis is in place and before wound closure.	Other: Pain scores (numerical rating scale at rest and motion); As the primary outcome of the present clinical study, pain scores will be assessed with numerical rating scale at both rest and motion on both knees.; Other: Secondary outcomes; Brief Pain Inventory (Short Form), WOMAC Osteoarthritis index, and Lower extremity functional scale will be used as the questionnaires for functional assessment. Rehabilitation physiotherapy will be assessed with knee range of motion (both active and maximal passive), muscle power at abduction and adduction, single leg stance test, six-minute walk test for assessment of the functional recovery of knee joints.
