Ask your surgeon: Best one to really answer the questions is the one who fixed the knee. You could have an infection, or be bearing too much weight on it or be too active too soon which could explain the problems. This does need evaluating.

May need to see MD: Usually pops have to do with abnormal movement or tears of cartilage. In the knee this could involve ligaments, tendons or the meniscus. It is good that there is no pain or swelling but if your knee feels unstable then use an elastic bandage like a Ace wrap to improve stability and see your doctor if this does not improve in a few days. ...Read more

Monitor: It is usually best not to jump to conclusions when only one months menstrual cycle is slightly different than the rest. Monitor your cycles over the next few months. If you are not satisfied with your level of cycle control see an Obgyn. Your leg weakness should be evaluated by your Primary care doctor or a neurologist. ...Read more

Can I get a knee scope while 2 months pregnant?

Not ideal: It is not recommended. There are occasions when general anesthesia is used during pregnancy, but we know it puts baby to sleep the same way it puts mom to sleep. So, we try to avoid any elective surgery cases during pregnancy. I would suggest waiting to have your knee scope done after you deliver. ...Read more

On the back of your insurance card there is likely a 1-800 number where you can call to have the covered benefits explained and addressed with you. ...Read more
