Knee Arthritis and Knee Replacement
Introduction to Knee Replacements
Did you know that Knee Replacements are more common than any other type of joint replacement? Usually, they’re a result of a painful condition affecting millions of Americans – arthritis of the knee. Your knee joint consists of three bones that are covered with cartilage and slide over one another: the end of the femur, the top of the tibia and the underside of the patella. Normally the cartilage is a smooth, glistening, white surface, which allows bones to move in an almost frictionless fashion. When you’re suffering with arthritis of the knee, your cartilage becomes worn and degenerates. It attains a roughened, uneven appearance and patches of cartilage flake off revealing the bony surface underneath.
Often, the pain and lack of function requires serious treatment minimally invasive knee replacement surgery; including, partial knee replacement surgery or total knee replacement surgery. The knee replacement surgeons at AOSMI have decades of experience diagnosing and treating arthritis of the knee in the most effective and painless way possible.
Common Symptoms of Knee Arthritis
Early symptoms of knee arthritis , possibly occurring after walking or playing sports, includes:
Eventually the disease becomes more severe and any movement brings on pain. The cartilage wears off the ends of the bone allowing the bones to grind together with every step. You may be unable to get up from a chair or walk around the house without pain. When medical management and injection therapy fail, our knee replacement surgeons will likely recommend total knee replacement surgery.
Common Surgical Procedures for Knee Injuries
Knee injury surgeries traditionally required surgeons to make large incisions, inflicting significant peri-operative pain, extended hospitalization and knee replacement surgery recovery time. Patients did well with surgery; however, they experienced significant pain and limitation of activity for the first three months after surgery. With the advent of mini-incision or minimally invasive knee replacement surgery combined with new techniques in pain management and anesthesia, both partial knee replacement surgery (for those whom suffer arthritis in only part of the knee) and total knee replacement surgery have become a more pleasant experience.
The Advantages of minimally invasive knee replacement surgery at AOSMI include:
Our surgeons are experienced with the most advanced knee replacement implants available today. The Deputy PFC Sigma Rotating Platform, High Flexion knee system combines proven performance in a mobile bearing design allowing unprecedented knee motion. The Smith and Nephew Genesis II Oxinium and Journey knee systems have a special ceramic coating for maximum longevity. The Zimmer Gender Solutions Knee System uses a high flexion design with modification of the femoral component to more precisely match female anatomy. The gender specific sizing often provides for a better fit with less overhang of the implant. Our knee replacement surgeons consider your age, sex, bone quality and activity level in selecting the optimal implants to suit your needs.
Navigation (computer assistance) for minimally invasive knee replacement surgery has been proven to increase surgical accuracy and precision in making bone cuts and placing components. It is expected to yield longer lasting knee replacements with less need for revision or repeat surgery.
