Sometimes even with a medical background, when I am receiving very much information at one time from my doctor, i may not remember some of the salient features. This is especially true if unfamiliar medical terms are being used. You are smart to inquire if there are issues you are uncertain about. An approach I use with some of my patients is to suggest that they write down their questions when they think of them. We can either review those questions at a patient care visit or sometimes over the phone. I hope that the information provided by the orthopedic surgeon was helpful.
