If you are experiencing pain or stiffness in one or both of your knees that is affecting your activity level and/or quality of life, you may have osteoarthritis, the most common form of arthritis. Osteoarthritis occurs when the cartilage, the connective tissue that serves as a cushion between the bone and joint, wears away, causing the bones to rub together and create pain and swelling. Osteoarthritis can have many causes, including age, gender, heredity, being overweight, having a previous knee injury or stress placed on the knee joint as a result of exercise or sports activities. If your osteoarthritis does not respond to non-surgical treatments such as medications or injections, you may be a candidate for a partial or total knee replacement.
Knee replacement is a surgical procedure that decreases pain, restores motion to the joint and improves the quality of life for patients with severe arthritis of the knees. We perform two types of knee replacement procedures at Yuma Regional Medical Center:
Partial Knee Replacement
In this minimally invasive procedure, the surgeon will make a small, 2-3 inch incision and remove only the diseased portion of the knee and replace it with an artificial component called an implant or prosthesis. Partial knee replacements are performed when only one or two sections of the knee needs to be replaced, either the inside (medial) part of the knee, the outside (lateral) part, or the kneecap. Compared to total knee replacement procedures, the benefits of partial knee replacement are a smaller incision and scar, less blood loss, a reduced hospital stay, decreased pain and a quicker rehabilitation/recovery time. Our surgeons use advanced technology called the MAKOplasty® Robotic Arm to perform this procedure.
Total Knee Replacement
This procedure involves replacing the damaged bone and cartilage in the knee joint with components made of ceramic alloys and plastic. The benefits of a total knee replacement are reduced joint pain, increased leg strength, improved quality of life and years of easier movement.
