The results of the study were presented at the American Association of Hip and Knee Surgeons meeting in Dallas. In the study, 216 patients were evaluated for pain control the first two days after surgery for almost one year. Half of the patients received the traditional pain control method with continuous femoral nerve blockade, and the other half received liposomal bupivacaine at the site of the surgery in the tissue surrounding the knee.
Many patients were able to walk comfortably within hours after surgery, according to Jason Davis, MD, a joint replacement surgeon at Henry Ford West Bloomfield Hospital and the study’s senior author.
“The pain scores for this injection technique averaged about 3/10, which is similar to the pain scores seen with our traditional method,” said Dr. Davis. “Patients had pain relief for up to two days after surgery and better knee function compared with the traditional method.”
