Best answer: Is the meniscus removed during knee replacement?

What is removed in knee replacement surgery?

During a total knee replacement, the end of the femur bone is removed and replaced with a metal shell. The end of the lower leg bone (tibia) is also removed and replaced with a channeled plastic piece with a metal stem.

Does an artificial knee have a meniscus?

The artificial meniscus is inserted into a patient’s knee through a small incision (two to three inches). Because of its special design, featuring a thick rim and a thinner center, the device stays in place – even when squatting – without being attached to bones or any other surrounding tissue.

What happens if the meniscus is removed?

If more tissue is removed, the knee is less able to sustain the load of walking, running, or other activities. With uneven load distribution, degeneration of the knee joint may happen at a faster pace than it would with an intact meniscus. In any surgery, there is risk of infection or bleeding.

Can the meniscus grow back?

The part of the meniscus removed does not grow back, but is replaced by fibrous tissue. There is an increased likelihood of developing osteoarthritis in patients who have undergone complete (total) menisectomy.

Is it better to repair or remove meniscus?

In general, it’s better to fix the meniscus than to remove it. Some types of tears can’t be fixed. For example, radial tears sometimes can be fixed, but it depends on where they are. But most horizontal, long-standing, and degenerative tears—those caused by years of wear and tear—can’t be fixed.

What happens if you wait too long for knee replacement?

If you wait too long to have surgery, you put yourself at risk of experiencing an increasing deformity of the knee joint. As your condition worsens, your body may have to compensate by placing additional strain on other parts of the body (like your other knee).

What is the best age to have a knee replacement?

In summary, TKA performed between the ages of 70 and 80 years has the best outcome. With respect to mortality, it would be better to perform TKA when the patients are younger. Therefore, the authors of these studies believe that from 70 to 80 years of age is the optimal range for undergoing TKA.

How long does an artificial meniscus last?

On average, a knee replacement implant may be anticipated to last about 15-20 years, so if you have the procedure in your 40s, you will most likely need to have a second, and possibly third surgery, called a ‘revision knee replacement,’ later in life.
