How accurate can a doctor get at diagnosing an injured knee without x-rays or MRI?
Answer: Doctors as well as some other health professionals have been using their fingers to make excellent diagnosis's long before the advent of MRI's. X-rays are not going to show soft tissue problems. So a doctor that is good at his or her craft will have skilled fingers and should be able to make a good call as to what is wrong..
Depends on the Doctor? My PCP is also a Sports Doctor, so as I have Arthritis, he is excellent at other problems like groin strain, tennis elbow and so on. Best of Luck
