How common is bilateral hip replacement surgery?

It is quite common for patients with widespread arthritis to need both hips replaced eventually. However, having them done simultaneously (bilateral hip replacement) is less common. The more standard approach is a staged bilateral replacement, where one hip is replaced, and the second hip is replaced a few months later after the first has healed.

A simultaneous replacement is typically reserved for younger, very healthy, and fit patients, as it puts more stress on the body and can make early rehabilitation more challenging.
