John M. Parenti, MD, Limb Preservation Annual Lectureship

This lectureship is dedicated to John M. Parenti, MD, orthopaedic surgeon at Geisinger for more than 30 years, for his contributions to clinical care and education in managing patients with challenging wound healing problems.

About John M. Parenti, MD 

John M. Parenti, MD, was born and raised in Scranton, Pa., by a family of Italian immigrants. He graduated from the University of Scranton in 1970 with a degree in biology/pre-med. He then pursued his medical education at Temple University where he earned his MD in 1974. He completed his residency in orthopaedics at Geisinger Medical Center in 1978 and a subsequent one-year fellowship in pediatric orthopaedics at the Alfred I. duPont Institute for Children in Wilmington, Del. 

Dr. Parenti returned to Geisinger in 1979 as an associate of orthopaedics, where he has maintained his practice for more than 45 years. He held the position of residency director (1990 – 2002) before transitioning to chairman of orthopaedics (2003 – 2011). He has also served as president of the alumni association for Geisinger orthopaedic residents. His clinical interests have included pediatric orthopaedics, adult reconstruction, diabetic foot care, limb salvage and amputation.

About the Parenti Lectureship

The Parenti Lectureship was established in 2011 by Arturo C. Porzecanski, PhD, and Nina Ramondelli Porzecanski, MA, to honor Dr. Parenti for his lifetime achievements as an exceptionally compassionate, competent and beloved orthopaedic surgeon.

This annual lectureship brings the nation’s top experts, best practices and latest innovations in limb salvage, preservation and wound care to Geisinger orthopaedic faculty and residents.

Arturo’s story

The endowment is also testament to the Porzecanskis’ gratitude for Dr. Parenti’s courage and expertise in saving Arturo’s legs, which were deemed non-salvageable following extensive internal muscle and nerve damage.

Read more about Dr. Parenti’s success with this high-risk case in the article “Functional ambulation without lower-leg muscles or nerves,” which was published in Acta Orthopaedica in 2019.

Limb salvage and wound care experts gathered at the 2023 John M. Parenti, MD, Limb Preservation Annual Lectureship to discuss the importance of multidisciplinary approaches, individualized patient care and challenges and strategies in managing complex cases.
