Arthroscopic medial retinacular plication with a needle-hole technique.

Patellar instability is a common problem resulting in anterior knee pain. The medial patellofemoral ligament, which is part of the medial retinaculum, is often injured, and this damaged structure can affect normal patellar movement. Medial retinacular plication can correct this main pathology of patellar instability. Many studies have shown good to excellent results with medial retinacular plication with or without lateral retinacular release. This medial retinacular plication technique can also be performed arthroscopically. Arthroscopic medial reticular plication with a needle-hole technique is a treatment that uses the less invasive technique of arthroscopy, does not require tissue grafts, and has a greater cosmetic advantage than open procedures.
