What is Knee Revision?
Knee revision, also known as revision knee replacement or revision total knee arthroplasty, is a surgical procedure to replace a previously implanted knee prosthesis with a new one.
Knee replacement surgery is typically done to relieve pain and restore function in people with severe knee joint damage or osteoarthritis. However, in some cases, the original knee replacement may fail or become damaged, and a revision surgery may be necessary.
Knee revision surgery involves removing the existing knee replacement and replacing it with a new prosthesis. The procedure can be more complex than the initial knee replacement surgery, as the surgeon may need to address issues such as bone loss, implant loosening, or infection.
Reasons for a Knee Revision
Some common reasons for knee revision include:
Prosthetic loosening or wear: Over time, the components of a knee replacement may loosen or wear, which can cause pain, instability, and decreased range of motion.
Infection: In some cases, an infection can develop in the knee joint, which can cause pain, swelling, and fever. If the infection cannot be treated with antibiotics, revision surgery may be necessary.
Implant breakage: Although rare, the components of a knee replacement may break or fracture, causing pain and instability in the joint.
Implant misalignment: In some cases, the alignment of the knee replacement may be incorrect, causing pain, instability, and decreased range of motion.
Patellar (kneecap) problems: Patients may experience pain or instability in the kneecap area after knee replacement surgery, which may require revision surgery to correct.
Trauma: Patients may experience trauma to the knee joint after a knee replacement, which may require revision surgery to repair or replace damaged components.
Allergic reaction: In rare cases, patients may have an allergic reaction to the materials used in the knee replacement, which can cause pain, swelling, and other symptoms.
When is Knee Revision recommended
Here are some common reasons why revision total knee replacement may be recommended:
Implant wear or loosening: Over time, the components of a knee replacement may wear out or loosen, causing pain and instability in the joint.
Infection: In some cases, an infection can develop in the knee joint, which can cause pain, swelling, and fever. If the infection cannot be treated with antibiotics, revision surgery may be necessary.
Fracture: In some cases, the bone around the knee replacement may fracture, which can cause pain and instability in the joint.
Instability: Sometimes, the knee replacement may become unstable, causing the knee to give way or feel like it is going to give way.
Implant breakage: Rarely, the components of a knee replacement may break or fracture, causing pain and instability in the joint.
Persistent pain: Some patients may experience persistent pain after knee replacement surgery that does not improve with conservative treatment measures, such as physical therapy or pain medications.
If you are experiencing any of these symptoms or have concerns about the function of your knee replacement, it is important to consult with your orthopedic surgeon. They can evaluate your condition and determine if revision knee replacement surgery is the right course of action for you.
Precausions to be taken after Knee Revision Surgery
After knee revision surgery, it is important to take the necessary precautions to ensure proper healing and avoid complications. Here are some general precautions that patients may need to follow:
Follow your surgeon’s instructions: Follow your surgeon’s post-operative instructions carefully, including medication, physical therapy, and any activity restrictions.
Rest and elevate your leg: Resting and elevating your leg can help reduce swelling and pain. Try to keep your leg elevated above the level of your heart as much as possible.
Use ice packs: Applying ice packs to the surgical area can also help reduce swelling and pain. You can use ice packs for 20 minutes at a time, several times a day.
Use assistive devices: You may need to use assistive devices such as crutches, walkers, or a knee brace to help support and protect your knee.
Avoid strenuous activities: Avoid activities that put stress on your knee, such as running or jumping, for several weeks after surgery.
Watch for signs of infection: Keep an eye out for signs of infection, such as redness, swelling, or drainage from the surgical incision. Contact your surgeon immediately if you notice any of these symptoms.
Attend follow-up appointments: Attend all follow-up appointments with your surgeon to monitor your progress and ensure proper healing.
It’s important to note that every patient’s situation is unique, and your surgeon may have specific precautions that are tailored to your individual needs. Always follow your surgeon’s instructions and reach out to them if you have any questions or concerns.
