Why is this better? Most of my patients find the surgicenter setting to be much more efficient and personalized than the hospital. They are happier at home with their own environment and comforts (and no one waking them up all night!) We are able to send nursing and physical therapists straight to their home to help recovery.
Additionally, many insurers will allow a lower copay for outpatient surgery.
Not everyone is a candidate to have outpatient knee replacement, but this procedure will become more and more common in the future. We are always looking to make knee replacement easier and less intrusive for our patients and I think this procedure is a great addition.
