A Total Knee Replacement is a very successful procedure that has helped thousands of patients relieve pain from osteoarthritis of the knee and regain mobility and – most importantly – their quality of life.

Dr. Nicholas Alexander is the founder of Mahwah Valley Orthopedic Associates in Mahwah and Clifton, NJ and a Board Certified Orthopedic Surgeon specializing in both the surgical and non-surgical treatment of hip and knee conditions.

Dr. Alexander completed his residency in Total Joint Replacement and Adult Reconstruction of the Hip and Knee t the prestigious John Hopkins School of Medicine and has performed thousands of Knee Replacements in his over 20 years practice. He also serves as the Chairman of the Valley Hospital Total Joint Center.

At Mahwah Valley Orthopedic Asssociates, Dr. Alexander believes in creating a unique approach for each patient based on his/her lifestyle and goals. He also believes that a Knee Replacement should only be considered when other more conservative options have not provided relief from chronic knee pain.

During a Partial or Total Knee Replacement procedure, Dr. Alexander uses the following steps:

Minimal amounts (several millimeters) of osteoarthritic bone are removed from the ends of the thigh and shin bones (femur and tibia) above and below the knee.

Special metal alloy knee replacement components sized for the particular patients anatomy, are cemented onto the ends of the bones, allowing the restoration of the alignment and range of motion to the knee to mimic the normal function of the knee
A ultra high molecular weight polyethylene plastic bearing is placed between the metal pieces.

Once the components are in place and the Dr. Alexander performs a series of tests to ensure the knee is moving properly, the small incision is closed using sutures and skin staples.
