General Orthopedics

Specialty: Lower Extremity Total Joint Replacement, Reconstruction and Revision.

Dr. Chertack attended Carleton College from 1973 to 1977; University of Illinois Medical School, Microbiology Graduate School from 1977 to 1982 and Rush Presbyterian-St. Lukes Orthopaedic Surgical residency from 1982-1987. Dr. Chertack started in private practice in 1987 and completed a Hip and Knee Reconstruction fellowship in 1990-1991.

During his international fellowship, Dr. Chertack studied gait laboratory analysis of total knee and total hip designs and surgery techniques in Chicago, techniques for revision of total hip and knees at Massachusetts General Hospital in Boston, and total knee and hip replacement design and techniques in Toronto and Europe (England, France, Germany, Switzerland and Italy).  Dr. Chertack has also had the rare privilege of doing joint replacement surgery on patients at the Central Clinical Hospital in Moscow.

Dr. Chertack has continued to advance and update his knowledge of modern joint replacement, while building on the past experience of over 25 years of orthopedic training. He currently includes the Zimmer Gender knee in his practice while acknowledging the potential benefits of the Johnson and Johnson Rotating Platform knee and the potential benefits of advances in plastic technology such as the Stryker X3, Crossfire, and Zimmer Prolong. In 2014 he was selected for inclusion in Buffalo Spree magazine’s Top Doctors list for orthopaedic surgery.

Currently many of his total knee replacements are done with the Stryker Navigation System (computer based) which allows for more consistent accurate results smaller incisions and potentially improved long term function for total knee replacements.

Advances in total hip replacements  material manufacturing and machining have allowed Dr. Chertack the use of larger head components to potentially allow implantation of joints in younger and more active patients, with potentially improved range of motion and longer wear over the life of the patient.  Equipment advances allow the use of smaller incisions, and advances in pain control usually allow for earlier and less painful mobilization/ambulation and discharge. In addition continued advances in plastic technology as noted above allow potentially longer function of conventional metal on plastic implants. He would be happy to provide you with an evaluation of your hip or knee arthritis to determine if these components are right for you.
