Clinical Trial Summary

Local anesthesia was performed on patients with total knee arthroplasty (TKA) through two different injection sites of local anesthetics and two local anesthetic drug . The pain score of patients after TKA was collected, then the analgesic effect of patients after TKA through two different injection sites and two different local anesthetic drug were analyzed and evaluated.

Intervention

Procedure:
• New local anesthesia injection site and new local anesthetic drug formulation.
The traditional injection site is the posterior joint capsule and the popliteal artery space (iPACK) plus multiple layers of tissues around the knee joint (posterior joint capsule, ligaments and subcutaneous tissue). The traditional local anesthetic formulation is 1% ropivacaine 10ml+ normal saline 40ml+10mg Morphine + 5mg dexamethasone. The new local anesthesia injection site is iPACK+Knee Cutaneous Nerve Block. The new local anesthetic formula is 1% ropivacaine 10ml+ normal saline 40ml+10mg morphine+1ml triamcinolone acetonide.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change of the pain score before and after surgery	A Visual Analogue Scale (VAS) is used to measure the amount of pain that a patient feels ranges across a continuum from none to an extreme amount of pain. Using a ruler, the score is determined by measuring the distance (mm) on the 10cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity.	pre-operation, 6hours after surgery, 24hours after surgery, 48 hours after surgery.
