MPFL Reconstruction: Restoring What Keeps the Kneecap in Place
The medial patellofemoral ligament is the primary restraint that stops the kneecap from sliding outward. When it tears, usually from a dislocation, kneecap instability becomes a recurring problem rather than a one-time injury. MPFL reconstruction replaces the damaged ligament using a graft, giving the patella a stable track to follow again.
Most patients are surprised by how targeted this procedure is. It's not a major reconstruction of the entire knee. Recovery is gradual but predictable, and the majority of patients return to their normal activities within four to six months.
Patella Realignment Surgery: Fixing the Root Cause
Some patients have kneecap instability because the bony anatomy itself puts the patella on a bad track. In those cases, MPFL reconstruction alone isn't enough. Patella realignment surgery repositions the attachment point of the patellar tendon so the kneecap sits where it's supposed to sit during movement.
This is common in younger patients who have had multiple dislocations and whose anatomy is working against them. Correcting the alignment at the source reduces the chance of the problem coming back.
Is Kneecap Instability Surgery Right for You?
Not every unstable kneecap needs an operation. Dr. Ayzenberg evaluates each patient individually, looking at the number of dislocations, anatomy, activity level, and how far conservative treatment has gotten. Kneecap instability surgery becomes the right answer when the joint keeps failing despite doing everything else correctly.
