Having a Knee Replacement

Safe sex positions

Many people have questions about sex after a knee replacement. It’s usually safe to have sex about 4 to 6 weeks after surgery. But you also have to feel ready and be comfortable.

For the first 3 months you have to protect your new joint. These pictures show you the positions that are safe and the ones that aren’t safe for your new knee joint.

  • Tell your partner what’s comfortable or if a position causes pain.
  • Make sure you’re comfortable before you start. Using pillows may help.
  • Move gently and don’t make sudden movements.
  • Make sure your partner doesn’t put their full weight on your new knee joint.

Safe positions

When you’re ready, you might try positions where your knee is supported, kept fairly straight, or bends only a little.





Unsafe positions

Avoid positions during sex where your knee is bending a lot or where there is a lot of pressure on your knee.
