What happens during surgery?
The following video was produced by the National Health Service in the United Kingdom. It does an excellent job explaining how the joint works, how osteoarthritis affects the joints, and what happens during hip replacement surgery.
Note: The hip replacement video references the use of acrylic cement to keep the prosthesis in place. At Penn State, and in the U.S., most hip replacements are performed using the bone ingrowth method, though both approaches can work very well.
