Dr. Penenberg performs hip and knee replacements using a minimally invasive surgical technique. This innovative technique involves less trauma to muscles and soft tissue and results in a significantly smaller surgical incision. The result for the patient is less postoperative pain, and earlier, easier mobilization.

Current research projects include analysis of major bone grafting of hip and knee reconstruction, management of infected prosthesis, coordination of computer-assisted hip and knee surgery, design analysis of hip and knee prostheses, and, development of patented hip and knee implants and instruments.

Dr. Penenberg is often called upon to share his expertise in his field at symposia around the world. He has presented at symposia for the International Society for Technology in Arthroplasty, and the Japanese Orthopedic Association. He is also a frequent presenter at the American Academy of Orthopaedic Surgeons annual meeting. Dr. Penenberg has co-authored a surgical textbook and contributed chapters to colleagues’ texts.

Dr. Penenberg is a graduate of the George Washington University School of Medicine, where he was the recipient of the Julius S. Neviaser Award in Orthopaedic Surgery. Dr. Penenberg performed his general surgical training at Albert Einstein Hospital in New York, and he completed his residency at Tufts – New England Medical Center and Massachusetts General Hospital in Boston. After his residency, Dr. Penenberg remained in Boston for two years to complete a specialty fellowship in reconstructive surgery of the hip and knee at Harvard University. During the fellowship, he performed as a research fellow and a clinical instructor of orthopaedic surgery at the Harvard University School of Medicine. He is an active member of the American Academy of Orthopaedic Surgeons, a member of the American Board of Orthopedic Surgery, and a Qualified Medical Examiner. Dr. Penenberg has demonstrated a commitment to new physicians choosing the orthopaedic specialty as an assistant professor at the University of Southern California School of Medicine and the Tufts University School of Medicine.
