What is the knee arthrodesis?

knee arthrodesis is a relatively unusual type of surgery in which the knee joint is melted into a single immobile unit. This type of joint fusion can be performed when the knee infections or tumors destroyed the joint tissue, but most often used when the replacement of the artificial knee joint has failed. Successful arthrodesis gives the stability of the knee and relieves pain, but has the disadvantage that the joint is no longer flexible. For this reason, the knee arthrodesis is usually performed on only one knee to maintain the patient mobile. Other people who can benefit from knee arthrodes include those who are young and involved in some great physical work. This is because arthrodesis is more likely to last and lasts than spare joints that may fail in the future, requires further knee surgery.

The knee arthrodesis surgery involves the preparation and trimming of the end of the bones that form the knee joint to join together at the right angle. Normally the knee is placed so that it is very slightly omoved and turned out of the middle line. Pieces of bone tissue, called bone grafts, are placed in and around the joint to stimulate healing and fusion. Sometimes the metal pins are set in the bones and attached to the metal frame that is worn outside the body. This is known as external fixation and serves to hold bones on site until the fusion is removed when the frame and pins are removed.

In another type of joint surgery, the knee arthrodesis is performed internally by fixing the bones together using nails. This is known as intramedular nailing and the nails remain inside the body. The third technique, called fixation of the boards, uses metal plates to hold bones together.

The most common complications associated with Knartrodes are EE when the bones fail. Sometimes infection or bones or metal fixations may break. The leg may also be shorter after surgery.

occasionally after arthrodes, one can experience pain in the lower back and hip and ankle on the same side as the fused joint. Pain can also occur in the oppositeknee, ankle and hips. The view of the knee arthrodesis depends on the method used and the reason for surgery, but in approximately 80 percent of cases the merger is successful and takes place within six months.
