People who were not considered for THR even 10 years ago can now have this operation. Obese, young, and elderly people can now successfully rehab and regain function with a new joint.

But there are some age-related risks that should be understood before having this kind of surgery. Older adults tend to have other health problems that can complicate recovery. Diabetes, cancer or the effects of cancer treatment, and hypertension are just a few of the more common conditions to consider.

Some older adults experience confusion or increased confusion after surgery. So far, we don't know how to predict this or prevent it from happening. Any change in mental function complicates recovery.

For example, the patient may not be able to follow directions. Putting too much weight on the joint or moving the hip too far in one direction can cause it to dislocate. A decline in cognitive function can also slow down the rehab process.

But studies do show that many people 85 and older have had a successful rehab outcome. Their overall function improved after THR. They were able to return to their daily activities. Some can even participate in recreational activities that were impossible before the operation.
