My mother has a calcification of knee joint in one of her knees but externally(doctors said that generally, the calcification is internal). She is 50 years old. She went to 2 doctors, one of them told her that it's not worth it to do a surgery until 65, the other one advised her to do it now. She feels a lot of pain before her regular period in the knee and she can't kneel comfortably. ( N.B: my mother is a little overweight)
Unfortunately, I can't upload the photo of the radiology she did but I need your advice.
