How long does it take for your knee to straighten after total replacement?

Recovery time and the ability to straighten your knee after a total knee replacement surgery can vary depending on several factors, including the individual's overall health, the complexity of the surgery, and their adherence to physical therapy. Here's a general overview of the timeline:

Immediately after surgery:

- The knee may be immobilized in a brace or cast to prevent excessive movement.

- You'll likely start gentle movement exercises under the guidance of a physiotherapist to prevent stiffness.

0 to 2 weeks after surgery:

- Active range-of-motion exercises are started to improve knee flexibility.

- The goal during this phase is to achieve full knee extension (straightening).

- Physical therapy sessions focus on strengthening the quadriceps muscles on the front of the thigh, which are crucial for knee extension.

2 to 6 weeks after surgery:

- Continuous physical therapy sessions emphasize regaining full range of motion, including complete knee straightening.

- You may be able to walk without any assistive device by the end of this phase.

6 weeks to 3 months after surgery:

- As your knee continues to heal and strengthen, you can advance your exercises and activities.

- This phase may involve more rigorous strengthening exercises, walking, and possibly light exercises like cycling.

- Your knee should be nearing its full range of motion, including complete straightening.

3 to 6 months after surgery:

- Most people have achieved full knee extension by this stage.

- Physical therapy may now focus on building strength and stability, reducing any residual swelling, and improving overall mobility.

It's important to note that everyone heals at a different pace, and the timeline for achieving complete knee straightening can vary. Consistent physical therapy, proper care, and patience are crucial for successful recovery. Your surgeon and physiotherapist will provide specific instructions and guidance based on your progress and individual needs.
