Based on your past medical history, physical exam, and current symptoms your doctor is recommending a procedure called knee arthroscopy.
It is safe to assume that you have probably been experiencing knee pain, or the sensation of your knee locking, popping, catching or giving out. These symptoms can be caused by knee injuries, loose fragments moving around inside your knee, or other medical conditions.
Many of these problems can be treated without surgery, through medication, activity changes, steroid injections or physical therapy. However, if these methods are unsuccessful, your doctor may recommend a knee arthroscopy. This procedure will allow your doctor to examine the inside of your knee joint and remove any loose fragments which might be causing problems.
At this time, your doctor feels that knee arthroscopy is appropriate for your particular situation.
