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.
