Artificial joint replacement surgery has a very high success rate and the vast majority of complications are treated accordingly. You should inform your surgeon of all relevant circumstances that may affect the surgery so that your surgeon is well prepared for possible complications. Possible complications are: 1. Infection: Infection can occur locally in the wound or deep around the prosthesis. Infection can occur during your hospital stay or after you have been discharged home, and can even occur several years later. Localized infections can usually be treated with antibiotics, while severe infections or deep infections more often require surgery or removal of the implant. Infections anywhere in your body can spread around your artificial joint prosthesis! 2, thrombosis: There are many factors that influence thrombosis, including a slowing of venous blood flow in the lower extremities due to reduced motion. If there is progressive pain and swelling in the calf and thigh, the possibility of thrombosis should be considered. There are several ways to reduce the incidence of thrombosis: use of anticoagulants; wearing elastic stockings; exercising the lower extremity muscles to speed blood flow; and wearing inflatable elastic boots. Despite all these precautions, thrombosis can still occur. If you still have ongoing pain or redness in your lower extremity after discharge, you should contact your surgeon promptly. 3. Loosening: The prosthesis may loosen within the fixed bone after the artificial joint replacement. This condition has the potential to cause pain. If significant loosening of the prosthesis occurs, revision surgery is likely to be required. There are constantly new methods of fixing the prosthesis that are conducive to minimizing the occurrence of loosening. 4. Dislocation: Occasionally occurs after total hip arthroplasty. It is the dislocation of the head of the prosthesis from the acetabular prosthesis. In most patients, it can be repositioned by non-surgical methods. Dislocation can also be treated with a specific brace. Most dislocations occur after complex revision surgery. 5. Wear and tear: All artificial joints are subject to a certain amount of wear and tear. Excessive wear and tear may cause the prosthesis to loosen and require revision surgery. 6.Prosthesis fracture: metal and polyethylene prosthesis fracture is relatively rare, but it can still happen. Once it occurs, revision surgery is necessary. Nerve damage: Although rare, it is possible for the nerves surrounding an artificial joint replacement to be damaged. This is more often seen due to transitional deformity of the joint or shortening of the limb that requires repeated strains during surgery. Nerve strain injuries can often be partially or completely recovered.
