Knee need

Today I had a conversation with a doctor who has no connection to orthopedics (or orthopaedics if you're Greek).  He has heard favorable  things about Dr. Conguista, that he is known to have a good reputation as a surgeon and is very conservative.    Moreover, he said that he is not knife-happy, that of 8 of his patients who consulted Dr. C. he only accepted 2 for the TKR surgery.  Only a favored few have survived the cut, so to speak.  Oh, joy.
