Hi Everyone, thanks for your nice feedback!
Ironwolf, if your surgeon says you can run then it should be ok. Ultimately though it comes down to your choice. You have to way up the risks and benefits. The risk is that running may reduce the life of the prosthetic and lead you to have revision surgery sooner than you'd like. Your surgeon could tell you how likely this is. I'm sure you know the benefits! As you say above, helps mood, manages weight and blood pressure and is an important part of your lifestyle.
If you do return to running I would do lots of work on your glutes as they help to support the hip area. There is also a blog about this that looks good;

Hope that helps
