ClinConnect Summary

This clinical trial is looking at how breathing exercises before orthopedic surgery, like knee or hip replacements, can help improve breathing function after the surgery. Researchers know that many people have trouble breathing for a few days following surgery, and they want to see if strengthening the breathing muscles ahead of time can make recovery easier and faster.

To participate in this study, you need to be at least 18 years old and have a history of smoking or certain lung problems that may increase the risk of complications after surgery. If you are eligible and decide to join, you will be asked to do some specific breathing exercises before your surgery. The goal is to see if these exercises can help you breathe better and recover more quickly afterward. If you have any serious health issues related to your lungs or other conditions that may complicate your participation, you may not be able to join the trial.
