The knee implant is made to bond tightly with the bone, but it can come loose over time. It is one of the more common causes of revisional surgery. Lose knee implants treated on time can save surrounding bones and improve results.
What is the cause of loosening?
- Normal wear and long-term mechanical stress
- Wear particles related to bone loss around the implant
- Low grade infection.
- Weak bone quality (osteoporosis)
- Misaligned implants
- High body weight or intense exercise
- Injury or fracture in the vicinity of the implant
Signs
- Pain when rising and walking
- Pain at nite or pain at rest
- A sense of instability or giving way
- Swelling
- Poor ability to walk
- Clicking or sensation of movement in the joint
Diagnose
The knee replacement surgeon in Indore will look at your knee and compare the current X-rays to previous ones to see if there are any gaps or shifts around the implant. Blood tests, CT scan or nuclear scan may be advised, and infection must be excluded.
Therapy options
If the loosening is minor and symptoms are acceptable, the doctor may choose to follow the patient with routine imaging studies and manage pain and activity levels. Significant pain or visible implant displacement usually suggests revision surgery. Lose parts are removed and replaced, often with special implants or stems to support weakened bone.
Why wait
If it is loosened further, it can erode bones and make surgery more difficult later.
Physical therapy
After surgery, physiotherapy helps you regain strength and walking. Your team will set the pace for recovery.
If your new knee hurts when you walk or feel wobbly, make an appointment to get a proper evaluation and the right plan.
