Their research will be recognized with the Knee Society Award for the best work on a surgical technique at the American Academy of Orthopedic Surgeons annual meeting, February 7-11 in San Francisco. Their initial study findings will be presented on Friday, February 10th at 5:42 PM Pacific Time.
The randomized, double-blind trial administered either bupivacaine, a common analgesic, or normal saline intraoperatively through a catheter in the joint to 150 primary, unilateral knee replacement patients.
The catheters released fluid continually over two postoperative days. Patients were asked to complete questionnaires at 5 PM on the day of surgery and 8 AM and 5 PM each day until discharge, as well as at a four-week follow-up visit.
Patients who received bupivacaine reported receiving the least pain and the lowest narcotic consumption. There was also no significant different in postoperative complications.
The study concludes that knee replacement patients may positively benefit from intraarticular delivery of a local analgesic to decrease overall pain levels and reduce the need for opioids following surgery. With no noted increase in infection risk, intraarticular delivery may also provide an effective alternative for pain relief in the immediate postoperative time period without the disadvantages encountered with epidural anesthesia, regional nerve blockade and patient controlled analgesia pumps.
"This study opens up a potential new option for better pain management post-surgery for our knee replacement patients. Though further study is needed, these initial results are promising," says Nitin Goyal, MD, of the Rothman Institute at Jefferson, an author on the study.
Additional authors on the study include: Nitin Goyal, MD; Javad Parvizi, MD; William Hozack, MD; Matthew Austin, MD; and James McKenzie, all with the Rothman Institute at Thomas Jefferson University Hospital.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
