Selected Presentations

Liguori, GA. “Enhanced Recovery for Total Knee Arthroplasty: A 360 Roundtable Discussion.” Presented at: 2018 World Congress on Regional Anesthesia and Pain Medicine. New York, NY.


Dr. Gregory Liguori's research efforts are focused on two primary areas. The first is hemodynamic effects of regional anesthetics. Peripheral nerve blockade and neuraxial anesthetics can have significant hemodynamic effects on both healthy and cardio-vascularly compromised patients. Prevention of these events and treatment when necessary are essential to the conduct of safe and efficient anesthetics.

The second area of interest is on spinal anesthesia for ambulatory surgery. The local anesthetic mepivacaine is a novel alternative to other more common local anesthetics for ambulatory spinal anesthesia. We are investigating the efficacy of mepivacaine as a routine alternative in this setting.

Industry Relationships

One of the goals of HSS is to advance the science of orthopedic surgery, rheumatology, and related disciplines for the benefit of patients. Physicians at HSS may collaborate with outside companies for education, research and medical advances. HSS supports this collaboration in order to foster medical breakthroughs; however HSS also believes that these collaborations must be disclosed.

As part of the disclosure process, this website lists physician collaborations with outside companies. The disclosures are provided by information provided by the physician and other sources and are updated regularly. Further information may be available on individual company websites.

As of February 21, 2023, Dr. Liguori reported no relationships with healthcare industry.

By disclosing the collaborations of HSS physicians with industry on this website, HSS and its physicians make this information available to their patients and the public, thus creating a transparent environment for those who are interested in this information.
