You had bilateral knee replacement surgery 2 years ago and now your is constantly giving out when you walk What going on?

Potential Issues:

1. Scar tissue or implant issues: Scar tissue can form around the implant causing tightness and restricting knee movement. The implant itself may have shifted or become loose, causing instability.

2. Muscle weakness: The muscles surrounding the knee help stabilize the joint. If the muscles are weak, they may not provide adequate support, leading to instability.

3. Joint alignment: During the surgery, the surgeon aligns the knee joint to ensure proper function. If the joint is not properly aligned, it can cause instability.

4. Nerve damage: Nerve damage can occur during surgery or due to the pressure from scar tissue. This can affect the communication between the knee and the brain, leading to instability.

5. Meniscus tear: The meniscus is a piece of cartilage in the knee that provides stability and cushioning. If the meniscus tears, it can cause instability.

6. Ligament injury: The ligaments in the knee help provide stability. If a ligament is injured or torn, it can lead to instability.

Recommended Actions:

1. Consult with your surgeon: It's important to see your surgeon to evaluate the source of the instability. They can assess your condition, identify any issues, and recommend the appropriate course of action.

2. Physical Therapy: Physical therapy exercises can help strengthen the muscles around your knee and improve stability. A physical therapist can design an exercise program specific to your needs.

3. Lifestyle modifications: Certain activities may put more strain on your knee and increase the risk of instability. Talk to your doctor about any modifications you may need to make to reduce symptoms.

4. Assistive devices: If you have ongoing instability, you may benefit from using assistive devices such as a cane or walker. These devices can provide additional support and reduce the risk of falls.

5. Avoid falls: It's important to take precautions to avoid falls that can further injure your knee. Ensure your home is well-lit, remove any obstacles or slippery surfaces, and use handrails when walking up or down stairs.

Remember, it's essential to follow the advice and guidance of your medical team. They can accurately assess your condition and recommend the best course of treatment to address your knee instability.
