What is Revision Total Knee Replacement Surgery?

Revisional total knee replacement surgery removes your existing knee implants and replaces them with a new one. Many people who undergo knee replacement surgery may have to undergo revisional surgery. It is because, over time, your prosthesis gets damaged. As a result, it can cause severe pain and discomfort. However, before performing the surgery, a surgeon understands the reasons for your knee pain and then treats the underlying conditions. Undergoing revision knee replacement surgery without understanding the pain may not yield effective results.

A revisional knee replacement surgery is an extensive procedure and requires proper planning. Without a treatment plan, you will not get the desired results. Moreover, a surgeon lays an operative plan and uses specialised implants and tools for the procedure. The surgery has a prolonged operative time, and so it must be done by skilful hands. To get positive results from the surgery, you may contact Dr. Rewat Laxman.

Why do implants fail?

Various reasons lead to the failure of an artificial implant. Sometimes, infection and normal wear and tear can damage the implants. Therefore, to maintain your knee health and improve the functions of artificial implants, you need revisional surgery. The possible causes of implants failure include:

  • Wear & tear, and loosening
    A surgeon properly aligns and fixes your implants at an exact location. They properly balance the soft tissues surrounding the implants. Moreover, they use cement to fix the implants to the bones. Even though the implant is accurately set, it may become loose after a few years. If you experience loosening or wear in your implants, you must undergo revisional surgery. If the implants become loose, they may make a crunching noise while bending your knees. Moreover, you may encounter problems while standing.
  • Infection
    The implants are made of durable plastics and metals. Unfortunately, these components act as a breeding ground for bacteria. As a result, you may develop infections after undergoing knee replacement surgery. Even if the prosthetics remain intact, you may develop pain and swelling because of infections. Therefore, infections make revisional surgery inevitable. However, the procedure may take different forms depending on the degree of infection. If there is a severe infection, an orthopaedic surgeon may replace the implants. In other cases, they may perform a simple washout of your implants.
  • Fractures
    If you have developed a knee injury or broken the bones around the implants, you may need revisional surgery. Moreover, any damage or disruption to the implant may require revisional surgery. After repairing the fractured bones, your surgeon fixes the implant in its usual position.
  • Instability
    If the soft tissues surrounding the knees do not support the implants, you may require revisional surgery. For example, if you cannot stand or walk properly after a knee implant surgery, you may need additional surgery. Instability may occur due to the loosening of soft tissues, improper positioning of implants, or inadequate fixation of prosthetics. In addition, soft tissue complications can cause pain in your knee region.
  • Patient-related factors
    Your age, weight, lifestyle, and surgical history decide the effectiveness of total knee replacement surgery. It is essential to keep yourself fit and active after the procedure. Your activity levels determine the need for revisional surgery. For example, if you are young and dynamic, you are more likely to undergo this procedure. Moreover, if you are obese, you may damage your prosthetics due to excess weight. Putting pressure on your knees can cause wear and tear. Similarly, you have a higher chance of infection and implant failure if you have previously undergone knee surgery.

If you have a failed implant, you may consider undergoing revisional surgery under the guidance of Dr. Rewat Laxman.
