Management of Postoperative Pain After Total Knee Replacement.
Summary
The purpose of this study is to compare two methods of postoperative pain management in patients undergoing total knee replacement.
Description
Patients undergoing total knee replacement will be assigned at random to receive one of two methods of postoperative pain management. Patients assigned to nerve block will receive regional anesthetic nerve block using an indwelling femoral nerve catheter and a single shot sciatic nerve block. Patients assigned to periarticular injection will receive periarticular local injection into the periarticular soft tissues at the time of knee replacement using a combination of ropivacaine, epinephrine, ketorolac, and morphine sulphate. Additionally, all patients will be given a standardized combination of oral analgesic medications preoperatively and postoperatively. All patients will receive a posterior stabilized total knee replacement through an medial parapatellar approach.

Medical and Biotech [MESH] Definitions
Autonomic Nerve Block
Interruption of sympathetic pathways, by local injection of an anesthetic agent, at any of four levels: peripheral nerve block, sympathetic ganglion block, extradural block, and subarachnoid block.
Nerve Block
Interruption of the conduction of impulses in peripheral nerves or nerve trunks by the injection of a local anesthetic solution. (Stedman, 26th ed)
Etodolac
A nonsteroidal anti-inflammatory agent with potent analgesic and antiarthritic properties. It has been shown to be effective in the treatment of OSTEOARTHRITIS; RHEUMATOID ARTHRITIS; ankylosing SPONDYLITIS; and in the alleviation of postoperative pain (PAIN, POSTOPERATIVE).
Pain, Postoperative
Pain during the period after surgery.
Meperidine
A narcotic analgesic that can be used for the relief of most types of moderate to severe pain, including postoperative pain and the pain of labor. Prolonged use may lead to dependence of the morphine type; withdrawal symptoms appear more rapidly than with morphine and are of shorter duration.
