About Me
I care deeply about giving each patient a near perfect surgical result as well as lasting durability of their artificial knee or hip. To this end, I use only implants that have the most favorable track records. I also carefully template each and every case weeks ahead of time to ensure that everything one might require is available for the case and that the patient's anatomy and function are optimally restored.
I do not accept payment or "consulting fees" from industry, thus I am able to maintain a high standard of integrity and freedom from corporate bias that is unusual in the Philadelphia marketplace.
Patient Comments
Dr Lorei and his assistant [...] have been awesome throughout my entire procedure
I already tell people about Dr. Lorei
Dr Lorie always takes the extra time to make sure that your care comes first.
Dr. Lorei took the time to listen and diagnose me. He didn't assume anything. From the tests, he ruled out what is not wrong so he could narrow in on what is wrong. I really appreciate his commitment to listening. Not something you get from some surgeons these days.
Dr. M. Lorei is a great surgeon and a trusted friend. I returned for repeat surgery after 17 years.
