What is a loose knee prosthesis?
Knee replacement failure refers to loosening or damage to an artificial knee after undergoing total knee replacement surgery. Loosening of the knee prosthesis can cause a great deal of pain and lower the range of motion in the knee. Often, loosened knee implants require a secondary revision surgery to repair or replace portions of the knee to restore your range of motion and improve knee stability.
What are the causes?
There are a number of reasons a knee replacement can fail or loosen, including:
- Improper fit during original procedure
- Wearing out over time
- Damage to the bone that surrounds the implant
What are the symptoms ?
It is important to visit an orthopedic specialist if you are suffering from any of these common symptoms of a loosened prosthetic knee:
- Knee pain
- “Loose” or unstable feeling in the knee
- Loss of range of motion
- Inability to balance
- Inability to put full weight on the knee
