Knee Replacement Revision Surgery

Knee Replacement Revision Surgery- Restore Your Knee Strength:

Knee replacement surgery restores a damaged, worn, or diseased knee joint. It is one of the most successful procedures, enabling people to live more active lives free of chronic knee pain. However, a knee replacement may fail for a variety of reasons. When this occurs, your knee can become unstable, painful and swollen. If your knee replacement fails, your doctor may recommend that you have a revision surgery.

A failed knee implant:

Although most total knee replacements are successful, over time problems such as implant wear and loosening may require a revision procedure. The revision surgery is the replacement of the previous failed total knee prosthesis with a new prosthesis. It is a complex procedure that requires extensive preoperative planning, specialized implants and tools, prolonged operating time, and mastery of difficult surgical techniques to achieve a good result.

Symptoms of knee replacement failure

-Knee pain

-Swelling

-Stiffness

-Mobility issues

Reasons for a revision

1. Misalignment: Knee replacement components have to be precisely aligned to work. If they do 2. not line up (deviation of more than three degrees from the mechanical axis), they can wear out too soon.

3. Loosening: Faulty components, wear and tear

4. Patellar misalignment or instability

5. Misalignment of knee (valgus/varus) leads to greater risk of failure

6. Patellar dislocation: causing severe knee pain when the patient walks

Infection: Infection is a potential complication in any surgical procedure, including total knee replacement surgery. Infections may occur after the surgery or years later.

Early infection: might be caused by intraoperative infection. This leads to swelling, inflammation, and pus formation.

Late infection that occurs years after surgery: Bacteria might enter a person's body through the wound or from an infection in other organs. If bacteria reach a person's new artificial knee joint, they may multiply and cause an infection. An infection that goes beyond the superficial tissues and gain deep access to the artificial joint almost always requires surgical treatment. Signs and symptoms of an infected joint replacement includes: pain, swelling, warmth, and redness.

Revision surgery for infection

Revision for infection can be done in many ways, depending on the degree of infection and how long the infection has been present. Debridement can be done in some cases where the bacteria can be washed out, the plastic spacer can be exchanged, and the metal implants can be left in place. In other cases, the implant must be completely removed and temporary cement spacer is placed that is treated with antibiotics to fight the infection. When the infection has been cleared, your doctor will perform a second surgery to insert a new prosthesis.

In some cases, there may be significant bone loss around the knee due to the infection. The surgeon might install metal pieces to reinforce the bone for the implant or fasten the implant to the bone. A revision requires the surgeon to use a specialized prosthetic device.

Prevention of infection after knee replacement surgery

An infection after knee replacement surgery can be a serious complication. Although infections occur in only a small percentage of patients, it can prolong or limit full recovery. Below is what you need to know to help protect your new knee so you can enjoy its mobility for years to come.

1. Avoid getting wounds

2. Avoid getting animal bites

3. Keep your house clean

4. Avoid water-contact to the surgical wound

5. Stop smoking

6. Consult your dentist before any dental procedures as antibiotics should be taken prior to the procedures. This is to protect the implants from bacteria that might enter the bloodstream during the dental procedure.

7. In patients with diabetes, maintain healthy blood sugar level.
