When is MPFL reconstruction needed?

MPFL repairs are best utilized when there is a very localized area of a tear at the time of knee dislocation in younger patients. The ligament is repaired, or secured with strong sutures. A MPFL reconstruction uses a tissue graft to completely reconstruct the torn ligament.

How long does a MPFL reconstruction take?

The surgery takes approximately 60-90 minutes to perform.

Does a torn medial patellofemoral tendon require surgery?

MPFL injuries typically occur during a forceful traumatic kneecap dislocation. This injury is most common among young, active females. Depending on the severity of an MPFL injury, treatment may involve surgical reconstruction, followed by physical therapy.

When to use medial patellofemoral ligament ( MPFL ) reconstruction?

Medial patellofemoral ligament (MPFL) reconstruction is commonly used to treat patellofemoral instability by restoration of the checkrein to lateral patellar translation.

When do you need reconstruction of the patellar tendon?

In recurrent or chronic patellar dislocations, it may be necessary to perform reconstruction of the MPFL. Reconstruction differs from repair in that graft tissue (such as a hamstring tendon) is used to replace or reinforce the MPFL. In these cases the MPFL reconstruction may also be combined with other patellar stabilization procedures.

Are there any complications after patellofemoral ligament reconstruction?

True complication rates after MPFL reconstruction surgery are difficult to ascertain because many series do not focus on complications and many series include patients who underwent multiple procedures to treat patellofemoral instability.

How is a patellofemoral ligament incision re-incised?

The previous medial patellar incision was re-incised. It was lengthened a bit inferiorly and superiorly. Dissection carried down through the skin and subcutaneous tissues. The medial retinaculum along the medial patellar border was incised to expose the medial border of the patella. Previous sutures were seen.
