Lateral retinacular lengthening is a procedure that lengthens the lateral retinaculum by cutting and sliding the superficial layer over the deep layer to allow a more controlled release of tension.

At a lower level, the deep layer is also released, allowing the patella to un-tilt.

When the patella is in a good position the two layers are sutured together in the new position.

 

Controlled retinacular tensioning

The lateral retinacular lengthening procedure allows the surgeon to control the tension in the retinaculum, so that the patella is in a better position but the lateral retinaculum is still functioning as a guy rope.
