Your doctor will talk with you about which option is best for you. This is then followed by intravenous antibiotics. In a 1-stage surgery-which is less commonly performed-the implant is removed, the joint is washed out, and the new implant is placed during the same surgery.When the infection has been cleared, your doctor will perform a second surgery to remove the antibiotic spacer and insert a new prosthesis. During this time, you will also receive intravenous antibiotics. This spacer is treated with antibiotics to fight the infection and will remain in your knee for several weeks. In a 2-stage surgery, the implant is removed, the joint is washed out, and a temporary cement spacer is placed in your knee.In other cases, the implant must be completely removed. In some cases, the bacteria can be washed out, the plastic spacer can be exchanged, and the metal implants can be left in place. Revision for infection can be done in one of two ways, depending on the type of bacteria, how long the infection has been present, the degree of infection, and patient preferences. Even if the implant remains properly fixed to the bone, pain, swelling, and drainage from the infection usually make revision surgery necessary. The implant may begin to lose its attachment to the bone. If an artificial joint becomes infected, it may become stiff and painful. Infection may occur while you are in the hospital or after you go home. Infection is a potential complication in any surgical procedure, including total knee replacement. Osteolysis (red arrow) has occurred around the tibial component, causing it to become loosened from the bone (blue arrow). Advances in material science and plastic quality have made osteolysis less common today than in past decades. In osteolysis, the bone around the implant deteriorates, making the implant loose or unstable. This immune response also attacks the healthy bone around the implant, leading to a condition called osteolysis. ![]() In some cases, tiny particles that wear off the plastic spacer accumulate around the joint and are attacked by the body's immune system. For these patients, there is a higher long-term risk that revision surgery will be needed due to loosening or wear. Also, patients who are younger when they undergo the initial knee replacement may "outlive" the life expectancy of their artificial knee. The cause of loosening is not always clear, but high-impact activities, excessive body weight, and wear of the plastic spacer between the two metal components of the implant are all factors that may contribute. Over time, however, an implant may loosen from the underlying bone, causing the knee to become painful. In either case, the implant was firmly fixed. During the initial surgery, the implant was either cemented into the bone or press-fit to allow bone to grow onto the surface of the implant. In order for a total knee replacement to function properly, an implant must remain firmly attached to the bone. It is a longer, more complex procedure that requires extensive planning, and specialized implants and tools to achieve a good result. In this procedure, your doctor removes some or all of the parts of the original prosthesis and replaces them with new ones.Īlthough both procedures have the same goal-to relieve pain and improve function-revision surgery is different than primary total knee replacement. If your knee replacement fails, your doctor may recommend that you have a second surgery-revision total knee replacement. It may also feel stiff or unstable, making it difficult to perform your everyday activities. When this occurs, your knee can become painful and swollen. Over time, however, a knee replacement may fail for a variety of reasons. ![]() #Revisions 1 free#In the vast majority of cases, it enables people to live richer, more active lives free of chronic knee pain. Total knee replacement is one of the most successful procedures in all of medicine. ![]() For patients whose procedures have not yet been rescheduled: What to Do If Your Orthopaedic Surgery Is Postponed.
