Greg G. Klingenstein, M.D.

Dr. Klingenstein grew up in northern New Jersey and attended Wesleyan University, where he graduated with honors. He then received his medical degree at the Mount Sinai School of Medicine with distinction in research. Dr. Klingenstein did his residency at the Tufts Affiliated Hospitals Orthopedic Surgery Program, which included a chief resident position at the New England Baptist Hospital. After residency, he completed two fellowships at the Hospital for Special Surgery in New York: Adult Reconstruction and Joint Replacement, followed by a second year of Hip Preservation training. The hip preservation program was lead by Dr. Bryan Kelly, and included a clinical rotation at the Schulthess Clinic in Zurich with Dr. Michael Leunig. Dr. Klingenstein has lectured nationally and internationally on femoro-acetabular impingement (FAI), and total hip replacement bearing options for young, active patients. He has published peer reviewed articles on FAI in athletes and biomechanics of total hip replacements.

Dr. Klingenstein’s practice includes tissue preserving hip and knee replacements, as well as joint preserving techniques for early hip disease. He specializes in non-operative and operative treatment of FAI, dysplasia, and residual effects of childhood hip disorders. Surgical options for younger patients with hip pain include hip arthroscopy as well as open surgical techniques.
