Ask Your Provider

With proper preparations through UPMC, it is possible to have your joint replacement surgery in the morning and be discharged to your own home that night.

Ask your provider if same-day discharge after joint replacement is an option for you.

National Walking Day


The first Wednesday in April is National Walking Day, and it encourages Americans of all ages to get out and stretch their legs!


Not only is walking is a great way to recover from hip surgery, knee surgery and other procedures ... it's a great way to prevent these procedures in the first place! Being active, even just by walking consistently, helps your overall well-being.


The specialists at Tri Rivers encourage you to maintain a walking routine that will help ensure your good health for years to come.
