Knee replacement surgery is meant to help you move more easily and feel less pain. If your knee feels unsteady afterward, it can be really concerning.
It’s normal to worry about your implant or fear you might need another surgery. However, an unstable knee does not always mean you will need another procedure.
Keep reading to learn more about knee instability after replacement and when revision knee surgery becomes part of the discussion.
What Are the Symptoms of Knee Instability?
Knee instability does not look the same for everyone. For some, it feels like the knee gives out during walking or weight-bearing activities. Others might notice it slips or feels unreliable when stepping off a curb. Sometimes, everything seems fine until you start moving, and then the problem appears.
These issues are hard to ignore. They can make walking or even just standing feel risky. There may be pain, and even if there is not, that unsteady feeling can affect your confidence.
Why Does Instability Happen After Knee Replacement?
A knee replacement works well only when every part fits together and stays steady. If any component is loose or incorrectly positioned, the joint may feel unstable and fail to provide adequate support.
There are several reasons a knee might become unstable. Sometimes it happens gradually, such as when supporting ligaments may become lax over time or parts wear down. Other times, it can start soon after surgery, especially if something shifted or you had a misstep.
An infection can also cause problems. If bacteria enter the area, infection can damage the supporting bone and soft tissues. Your knee may swell or feel warm and stiff.
Does Instability Always Mean Revision Surgery?
Not always. Physical therapy may improve symptoms in select cases, particularly if muscle strength or coordination needs improvement. A brace or temporary changes in movement may also help.
However, if your knee keeps giving out, there could be a more serious problem. Sometimes the parts are not lined up correctly, or the implant may be loose. In these cases, exercises and braces will not solve the issue. Revision knee replacement surgery may help restore stability and improve function.
Revision knee surgery helps correct problems from the first procedure. Sometimes, a damaged part needs to be replaced. In other cases, the joint needs to be realigned. These surgeries are complex and require careful planning and skilled hands in the operating room.
