Total joint replacement (also known as total joint arthroplasty) is regarded among the most valued developments in the history of orthopedics. The procedure provides the surgeon the ability to relieve pain and restore function to patients whose joints have been destroyed by trauma or disease.
An ongoing concern in joint replacement, however, focuses on the increased friction and wear of the joint when utilizing man-made implants. Compared to healthy, organic cartilage surfaces, which have a surface friction of nearly zero, the friction between these man-made bearing surfaces are hundreds of times higher. This friction subjects the implant to wear that can limit the longevity of the joint replacement and induce inflammatory responses in the surrounding area of the joint itself.
Fundamental to replacing damaged joint surfaces with implants fabricated from man-made materials, then, is the requirement of producing a low friction bearing to minimize surface wear, inflammation in surrounding tissues and possible eventual loosening of the implant, resulting in the need for additional surgery.

The SNEAKER© Project (Super Nutrition Education for All Kids to Eat Right) is a nutrition education program directed by HSS's Education Division and designed to provide culturally sensitive education information specific to English, Spanish, and Chinese speaking children and their families in New York City.
The free cookbook developed by the project - along with nutrition lessons and helpful links to other websites - is available in its entirety in both PDF and interactive versions on HSS.edu via the above link. The PDF is posted in English and Spanish.
Serving the Needy: FAMI Medical and Surgical Missions to the Philippines: Filipino American Medical Inc. (FAMI) is a non-profit corporation that was founded in 1999 by Hospital for Special Surgery's Niles Perlas, CRNA, and friends in New York City. FAMI brings American and Filipino-American physicians and other medical professionals to the Philippines to serve the poor.

Established in 2003, The Kathryn O. and Alan C. Greenberg Center for Skeletal Dysplasias at Hospital for Special Surgery is dedicated to the comprehensive medical care of people of all ages with skeletal dysplasias.
The first of its kind in New York City, the Center brings together a multidisciplinary team of health care professionals committed to improving the quality of life for people with skeletal dysplasias through clinical care, research, and education. To learn more about the education and research initiatives currently underway at the Center, along with the clinical care currently available, access the linked title above. Also available are three Center newsletters in PDF form as well as a 7-minute video about the work being done at the Center.
