ACL reconstruction: Symptomatic instability resulting from a torn ACL is usually treated with ACL reconstruction. A piece of a torn meniscus can become stuck or lodged anywhere to include under the patella, especially if it becomes a free fragment or loose body (rare). More common in the area of the patellofemoral joint is synovium/scar tissue, or a cartilage flap from the patella or trochlea.

Usually surgery.: Surgery is usually recommended for an ACL tear. It generally does not heal on its own, and leaves the knee vulnerable to episodes of instability. Sometimes a stump of the old ACL can get stuck under the patella.

Possible meniscus: You need to be seen by an orthopaedic surgeon to evaluate your knee for a possible meniscus tear. You need an exam and an mri. If torn, arthroscopic surgery can trim the tear and improve your symptoms quickly. This is a picture of your meniscus seen here. It is the shock absorber between the femur and the tibia cartilage surfaces. This one is normal.

A member asked:

My 11 year old son cut his shin open on a piece of metal, does not need stitches, we can't remember when his last tetnus shot was, what are symptoms to look for ? Thank you.

Things to consider. : Your son is 11 years of age and he is due to have a tetanus booster at this age. As for the shin cut, hopefully it was cleaned with hydrogen peroxide and treated with an antibiotic ointment. The best thing to do is to schedule an appointment with his pediatrician or family physician to get his shot and check on his cut.
