Expertise in Knee Surgery
As a member of the European Knee Society, The Knee Society (USA), and the International Knee Society, Dr. Boettner is recognized internationally for his expertise in knee surgery.
He specializes in minimally invasive, muscle sparing and robotic-assisted total knee replacement, as well as partial and uni-compartmental knee replacement.
Dr. Boettner maintains that minimally invasive surgery can reduce surgical trauma, aiding in early recovery and rehabilitation. Patients also appreciate a more cosmetically appealing incision.
As part of a patient centered holistic approach he offers nutritional advice, exercise protocols, and non-operative injection treatments. His goal is to preserve the natural knee whenever and for as long as possible, providing personalized surgical solutions when joint replacement becomes necessary. Dr. Boettner is among the world’s most experienced surgeons for patients suffering from complex knee deformities, stiffness and instability secondary to osteoarthritis.
Pioneering Expertise in Hip Surgery
As one of a few experts in New York, he performs anterior, anterior-Bikini, posterior and STAR approach total hip replacements as well as hip resurfacing. This comprehensive range allows him to discuss with his patients the pros and cons of each approach and pick the best treatment option for the patients’ individual situation.
Dr. Boettner emphasizes that there is no universally right or wrong treatment decision. Instead, each approach is carefully tailored to the patient's individual needs and goals. For example, hip resurfacing may be an appropriate option for a 45-year-old police officer, while an anterior hip replacement may be better suited for a 55-year-old woman hoping to return to yoga.

Whether patients are local, national, or international, Dr. Boettner’s team provides a seamless and caring surgical experience.
