Thromboembolism. Inflammation, swelling and lack of movement of the lower extremities increase the risk of blood clots in the venous system of the legs (thrombosis). Such a clot can break away from the wall of a vein (embolus), and together with the blood flow into the lungs. Pain and swelling, usually in the calf or thigh, arising after surgery to replace knee joint, may indicate the formation of thrombus water from the deep veins of the lower extremity. Teva Pharmaceuticals may also support this cause. Chest pain, shortness of breath, coughing up blood or loss of consciousness may be signs that a blood clot fell into the lungs and cause pulmonary embolism. Patients who have signs of thrombosis or embolism, should immediately contact a doctor. Infection.

Infection after knee arthroplasty a relatively rare but very serious complication. Fever, chills, sudden deterioration of the surgical wound, increasing redness or swelling may indicate an infection and require immediate medical attention. Postoperative infection is treated with antibiotics and, sometimes, draining excess fluid from the damaged area. If the infection continues to spread despite treatment, it is possible to remove artificial arthroplasty and reimplantation after its removal. Complications of patellofemoralnogo joint. As a result, the operation may cause damage to the junction of the patella and femur: offset, weakening or rupture of ligaments, fracture of the patella. In some cases may require surgical treatment. In the case of serious damage may require removal of the prosthesis.

Damage nerves. The most frequent neurological complication after knee joint replacement is a paralysis of the peroneal (fibular) nerve. Symptoms of this damage – numbness, tingling and muscle weakness legs. With their when necessary to remove the bandage from his knee and lock it in driving condition, to reduce pressure on the affected nerve. Conclusion. Complete replacement of the knee joint is a common surgical procedure which may help in cases where non-operational treatment (use knee pads or orthotic insoles and medication) is not helping. The operation involves replacing all three parts of the knee joint (see Fig. 1) prosthesis, in order to reduce pain and improve the functioning of the joint. Most candidates for surgery suffer from pain in the joints due to arthritis. In preparation for the knee replacement patient should undergo examination including a survey and physical examination, X-rays, laboratory tests, and discuss with your doctor the benefits and potential complications of surgery and get information about alternative therapies. The operation is done under anesthesia for the temporary immobilization and pain relief. The surgeon makes the incision to access the knee joint cavity, and then removes part of the cartilage and bone tissue from the lower surface of the femur and the upper surface of the tibia. Next is implantation of an artificial joint made of metal and plastic. After surgery, the patient receives a medication to prevent infection and pain. Also taken measures to prevent thrombosis – blood-thinning drugs and devices for compressing the legs or elastic stockings. Some patients are offered the use of devices for continuous passive motion – a mechanism that lifts and moves slowly operated leg. After the operation is necessary to work closely with a physical therapist to strengthen the muscle strength and resumption of the normal range of motion of the knee. The patient can return to normal activity within three – six weeks after surgery, after completion of rehabilitation programs that can deal with views Sports with a small load on the knee (walking, swimming, cycling). Postoperative complications are rare, and largely can be prevented by careful postoperative care.
