Around 790,000 knee replacements are performed each year in the United States, providing relief and improved mobility to people suffering from chronic knee pain.

While these procedures are highly effective and life-changing for many, complications can sometimes arise. One such issue is a loose knee replacement, which can cause discomfort, instability, and reduced joint function.

Recognizing the symptoms of a loose knee replacement early is crucial for addressing the problem and ensuring long-term joint health.

Common Causes of a Loose Implant Replacement

A loose knee replacement can occur when the artificial joint components become detached from the surrounding bone or lose their secure fit. This issue may arise due to:

  • Natural wear and tear
  • Infection
  • Poor bone quality

Although modern materials and surgical techniques make knee replacements durable, they are not immune to complications over time. Patients should be aware of potential symptoms so they can seek medical advice if needed, as early intervention often improves outcomes and reduces the risk of further complications.

Key Symptoms of a Loose Knee Replacement

Identifying the signs of a loose knee replacement early can help prevent complications. Here are the most common symptoms to watch for.

Persistent Pain

While some discomfort is normal during recovery, persistent or worsening pain long after your initial recovery period could indicate a loose implant. Pain might be felt during everyday activities like walking or even while at rest.

Swelling and Stiffness

Unusual swelling or stiffness in the knee joint can signal inflammation caused by a loose implant. This may make it harder to bend or straighten your leg.

Instability or Weakness

A loose knee replacement may cause your knee to feel unstable, making it difficult to bear weight or maintain balance. Patients often describe this as a sensation of the knee “giving out.”

Clicking or Grinding Sensations

If you feel or hear unusual noises, like clicking or grinding, during movement, it might indicate that the components of your knee replacement are not properly aligned or securely fixed.

Decreased Range of Motion

A gradual reduction in your knee’s ability to move freely could be a sign that your replacement is not functioning as it should. This is especially concerning if the joint was previously working well after surgery.
