Arthroplasty and Ankle Replacement

 

Reasons for ankle replacement

Surgeons usually recommend ankle arthroplasty surgery to treat severe arthritis that has not been successfully treated using conservative treatments. Arthritis is a broad term used to refer to a wide range of joint surface erosive disorders. A soft layer of cartilage that allows the joint to move without pain covers joint surface. The surface of this layer may wear away and wear out due to various reasons. The cause of this condition is often unclear. As the articular cartilage wears out, the bones’ end rob against each other, causing pain. Many complications can cause arthritis.

 

Causes of Arthritis

There are some causes of arthritis including inflammatory diseases such as rheumatoid arthritis, joint wearing away and wearing out- the incidence of ankle disorders can cause premature osteoarthritis- traumatic fracture, increased pressure due to overuse, avascular necrosis (decreased blood supply), and infection and connective tissue abnormalities.

Other causes that need ankle replacement surgery include severe ankle fracture in elderly patients with osteoporosis (a disease that decreases bone volume resulting in increased bone fractures), tumor formation or extra ankle joint growth. Having an ankle surgery before, it would not be an appropriate choice for you to undergo ankle replacement surgery because of suffering from any case of ankle arthritis. In some cases, ankle fusion is a better option. The surgeon chooses the best option based on the patient's condition.

 

Ankle replacement surgery

 

An ankle replacement surgery is often performed using anesthesia. It means you are somehow asleep and feel no pain. Anesthesia may be spinal whereby you become numb from the waist down. If you are anesthetized this way, you will be given some medication to make you feel comfortable during surgery. The surgeon makes a cut at the forepart of the ankle joint so that the ankle joint is apparent. After that, the surgeon gently moves through the nerves and blood vessels. Then, he/she removes the damaged bone or cartilage and replaces the damaged parts. Metal parts of the new artificial joint, is joined to bones’ cut surfaces to hold firm the prosthesis in its correct position. Finally, he/she inserts a piece of plastic between the two metal parts.
