How do I know if my knee replacement is failing?
What are the signs of knee replacement failure? The most common symptoms of a failed knee implant are pain, decrease in joint function, knee instability, and swelling or stiffness in the knee joint.
When does a knee replacement go bad?
Most implants should last 20 years or longer, but some may fail sooner or at higher-than-expected rates. This can lead to recalls or to patients suing the manufacturer. The American Association of Hip and Knee Surgeons says there is a 0.5 to 1 percent chance each year that a patient’s knee implant will fail.
Can you damage a knee replacement?
If you fall on your knee soon after surgery when your joint replacement is still healing, you may damage the prosthetic implant. In that case, you might end up needing revision surgery. Until your balance, flexibility and strength are improved, use your cane, crutches or walker and be extra careful when walking.

Why does my knee still hurt 6 months after knee replacement?
A: Recovery from surgery can take several months, so it’s not unusual to still have soreness in the knee that was replaced. As the intensity of rehabilitation exercises increases, more strain is put on the muscles and joints that have not been used in a period of time.
Why does my knee replacement feel heavy?
As time goes on, knee replacement stiffness may linger due to scar formation or adhesions (fibrous tissue that grows and attaches to the knee implant and other tissues, restricting movement). Scar formation helps heal the incision, but too much scar tissue can cause problems.
How can you tell if your knee replacement is too big?
When too little patella bone is resected, the total thickness of the reconstructed patella is increased and can result in abnormally high forces created between the patella and the femur when the knee is flexed. Patients often complain of anterior (front) knee pain, tightness and have limited flexion.
