Problems With Knee Replacements

Having knee replacement surgery is not a decision to be made lightly. The surgery comes with some risks and does not always work as well as the patient would hope. People generally decide on knee replacements because of debilitating pain or inability to continue with everyday activities due to immobility. The most prevalent reason for knee replacement surgery is knee osteoarthritis, a degenerative joint disease.

Blood Clots

• One serious possible complication is blood clots, which can form in the leg veins and pelvis after surgery. Doctors perform preventive measures such as prescribing blood thinners after surgery.

Infection

• Another problem with knee replacements is the chance of infection, which can occur soon after surgery or even years later. Infections may require removal of the replacements.

Stiffness

• Stiffness can remain, and sometimes people see little improvement with mobility or bending.

Time Frame

• Knee replacements generally last 15 to 20 years, so people younger than 60 years old should avoid this surgery if possible. If a replacement wears out, a revision knee replacement is usually not as successful as the first surgery.

Metal Detectors

• A common problem with knee replacements is that they set off metal detectors, particularly sensitive ones at airports.
