does not always require surgical correction but as there are loose bodies in your joint space, the surgeon would consider an Arthroscopy
to remove the body present and also try to correct any ligament injury
if possible. In your case a Diagnostic Arthroscopy is better as it will help to know the problem areas and remove the loose body. You will need about 6 weeks of rest after the procedure. The lose bodies can cause arthritis
in the future. We suggest you go with the doctor's advice.
