A Professional Footballer With a Kneecap That Kept Dislocating: MPFL Reconstruction
A professional footballer came to Dr. Amr Elyamany with a kneecap (patella) that dislocated with almost any movement or sport. Here is what that means and how the problem was solved.
Why it could not be left
If a repeatedly dislocating kneecap is left alone, it can lead to arthritis behind the kneecap (patellofemoral osteoarthritis) later on, which makes the problem bigger and may eventually force a joint replacement.
The operation
The only solution was to repair the tendon and ligament that keep the kneecap in place. A graft taken from the patient's own body (a tendon) was secured with anchors and sutures. It was fixed inside the kneecap and then fixed again to the thigh bone. This rebuilds the inner ligament between the kneecap and the thigh bone, known as the MPFL (medial patellofemoral ligament).
Why it needs such precision
This is a very delicate operation. The length must be calculated to the millimetre between the two fixation points, otherwise the knee can become stiff. The operation went well and the player is expected to return to the pitch.
Key takeaway: A kneecap that dislocates repeatedly should be treated early: rebuilding the MPFL can restore stability and protect the joint.
When to see a doctor
- A kneecap that slips out, or a knee that feels as if it will
- Repeated dislocations with sport or twisting
- Pain at the front of the knee after a dislocation
