Board-certified and fellowship-trained Dr. Gregory Klingenstein grew up in northern New Jersey and attended Wesleyan University, where he graduated with honors. He then received his medical degree at the Icahn School of Medicine at Mount Sinai with distinction in research. Dr. Klingenstein did his residency at the Tufts Medical Center Orthopedic Surgery Program, which included a chief resident position at the New England Baptist Hospital. After his residency, he completed two fellowships at the Hospital for Special Surgery in New York, one in 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 femoroacetabular 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 the nonoperative 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. The focus of Dr. Klingenstein's practice is in hip arthroscopy, labral tears, hip preservation, hip impingement, and femoroacetabular impingement (FAI).
