About Philip Kaiser, MD

Dr. Kaiser is a fellowship-trained orthopaedic surgeon specializing in injuries and conditions of the lower extremity. He completed his undergrad degree in economics and psychology at Harvard College. As an undergraduate he was a 4-year member of the national championship heavyweight men’s crew team and represented Canada internationally as a competitive rower. He received his MD from Columbia University. He then completed the Harvard Combined Orthopaedic Residency Program and was named Chief Resident at Beth Israel Deaconess Medical Center in his final year. After his residency, he attended the OrthoCarolina Foot and Ankle Fellowship in Charlotte, NC focusing on the newest surgical treatments for orthopedic trauma, sports-related injuries, cartilage restoration, ligament and tendon disorders, foot and ankle reconstruction including ankle replacement, forefoot and bunion correction, diabetes and Charcot, and minimally-invasive foot and ankle surgery.

He brings his background in limb salvage and amputation to Mass General and has partnered with a team of orthopaedic and plastic surgeons to provide clinical evaluation and consultation for patients considering major limb reconstruction, limb salvage and amputation. The Interdisciplinary Care for Amputees Network (ICAN) at Mass General is a unique program with the aim to maximize the outcomes of limb salvage and amputation patients through a multidisciplinary approach. Cases involve boney reconstruction or fusion, thin or multiaxial correction frame application, peripheral nerve management including targeted muscle reinnervation and regenerative peripheral nerve interface, and osseointegration amputation surgery for patients with failed use of conventional socket prostheses.

Dr. Kaiser also hopes to integrate his fellowship training in minimally invasive (MIS) foot and ankle surgery in his practice, both in the traditional forefoot setting but also in cases of limb salvage to minimize infection and wound complications. He is actively beginning research in these areas to advance the field and scope of MIS application.

Outside of the operating room and clinic Dr. Kaiser is actively involved in academic research and teaching, with more than 20 peer reviewed publications in the past five years. He is interested in the study and development of new Orthopaedic implants and devices, which advance the field of orthopaedics and improves the lives of patients.
