We just bought adjustable beds from Costco on-line, and are really pleased with them. Long after your hips heal, you'll still enjoy them for reading in bed, different sleep positions, - even built in leg massages. They're delivered by Costco's 'white glove' service in major centres- includes set-up in your home.

We bought the 'kingbed-size' (which is actually 2 twins side-be-side) - to assist in my wife's recovery from surgery, hip problems and long-term sleep apnea, but I was pleasantly surprised to find that I enjoy the different features too.
I know you're looking to rent - but this might be a long-term solution.
Best of luck in a speedy recovery.
