Considering a Knee Revision? Here’s What You Need to Know
If you had a total knee replacement more than 15 years ago and are starting to notice pain, swelling, or reduced mobility, you may be a candidate for knee revision surgery.
Over time, knee implants can wear out or loosen. This may happen because of changes in the bone, wear of older materials like polyethylene plastic, or loosening of the bone cement used during your original surgery. As these parts break down, your body tries to respond—but in the process, it can create inflammation that damages nearby bone and causes discomfort.
What Is Knee Revision Surgery?
Knee revision surgery involves removing the worn-out components of your original implant and replacing them with new parts that better fit your current anatomy. These implants are specially designed to support knees that may have bone loss, weakened ligaments, or changes from the original surgery.
What’s Different About a Knee Revision?
Knee revision surgery is more complex than a first-time knee replacement. Here’s what to expect:
- Slightly longer hospital stay: Usually around 3 days.
- Extended recovery time: Physical therapy is more intensive and lasts longer than with a primary knee replacement.
- Longer surgery duration: Depending on the condition of the knee, surgery can take between 1.5 to 3 hours.
- Higher risk factors: Because the knee has been operated on before, the chances of infection or blood clots are slightly increased.
Most patients undergoing a revision are a bit older, which can also affect recovery. However, when performed for the right reasons—and by a surgeon with experience in knee revisions—outcomes are often very good.
When Is Knee Revision the Right Choice?
Pain alone doesn’t always mean you need a revision. The most successful results come when the cause is clear. These may include:
- Loosening or wear of implant components
- Instability in the joint
- Damage to surrounding ligaments
- Infection
- Improper positioning of original implants
