Knee Surgery

Chronic knee pain caused by arthritis or injury can make it hard to perform daily activities, such as walking or climbing. If painful damage to the knee joint has limited your mobility and affected overall quality of life, your doctor may recommend knee replacement surgery.

Whether you suffer from osteoarthritis, rheumatoid arthritis or a fracture to the hip joint, the Center’s care team has the skills and experience required to offer total and partial hip replacement surgery to relieve hip pain and restore quality of life. Our team is also expertly skilled in the treatments for athletic, sports and running injuries to the hips and knees.Our surgeons are versatile at the most advanced surgical techniques, including Anterior Hip, a tissue-sparing alternative to traditional hip replacement, providing the potential for less pain, faster recovery and improved mobility because the muscle tissues are spared during the surgery.
