A  new study published in The New England  Journal of Medicine, states that arthroscopic knee surgery does not  alleviate the symptoms you may experience with osteoarthritis of the knee.  Arthroscopic knee surgery is the most common  orthopedic knee surgery, in which a small camera is fed through an incision in  the knee to remove damaged or torn cartilage.   This procedure is meant to extract the fragments of cartilage that are  causing the pain and stiffness in the knee, and to smooth those surfaces to  provide comfort and relief.  The study  suggests that arthroscopic surgery should be the last course of action, after a  regimen of physical therapy and painkillers (or supplements) have been  evaluated.
The  study was performed by researchers at the University of Ontario  in Canada,  where they evaluated 178 patients with osteoarthritis of the knee.  All of the patients were an average of 60  years of age.  The team performed  arthroscopic knee surgery on half of the subjects, and all of the individuals  received physical therapy and anti-inflammatory medication (ibuprofen or  acetaminophen).  The individuals were  evaluated after two years on this plan.   The researchers found that there was no apparent difference between the  two groups- those that had the surgery and those that did not.  The arthroscopic surgery did not improve the  mobility and function of the joint, anymore than the individuals on physical  therapy and medication alone.
You  should always talk with your doctor about all of your options before you have a  surgical procedure.  It has been  mentioned that MRI testing has  allowed doctors to over-perform surgical procedures like arthroscopy.  Your doctor may want you try a supplement  with Glucosamine and Chondroitin first, like Synflex®, and to start a moderate  exercise program.  Physical therapy may  also be very beneficial, as your progress will be monitored and the therapy can  be adjusted if you do not begin to see signs of improvement.  Arthroscopy is beneficial in some conditions  of the knee, but you should be aware of its relationship to osteoarthritis, and  the risks.
