I keep getting patella dislocation, 16 years old, help!?

Surgery indicated: Recurrent patellar instability in an active teenager or adult may benefit from surgical stabilization via an MPFL (medial patellofemoral ligament) reconstruction, and/or a distal realignment procedure that moves the tibial tubercle medially to redirect the forces that tend to pull the patella out of its normal trcohlear groove. See your Orthopaedic surgeon for a thorough discussion of your options
