Medial Patellar Retinaculum
- The medial patellar retinaculum is a ligamentous structure that plays a crucial role in maintaining patellar stability 1, 2.
- It is often injured in cases of patellar dislocation, which can lead to chronic instability and pain 3, 4.
Injury Treatment
- Various surgical techniques have been described to repair or reconstruct the medial patellar retinaculum, including primary repair, reefing, and imbrication 1, 3, 2.
- Medial retinacular plication with a needle-hole technique is a minimally invasive arthroscopic procedure that can correct patellar instability without requiring tissue grafts 5.
- Medial patella retinaculum plasty is a surgical technique that can restore both static and dynamic stability in adolescents with habitual patellar dislocation 4.
- The choice of treatment depends on the severity and pattern of the injury, as well as the presence of any associated pathology 3, 2.
Surgical Techniques
- A new minimally invasive surgical technique for medial retinaculum repair following traumatic patellar dislocation has been introduced, which achieves reinforced reattachment of the torn region of the medial retinaculum 1.
- Medial patellofemoral ligament repair is best indicated in the acute setting, particularly if there is a patella- or femoral-based avulsion 3.
- Arthroscopic medial retinacular plication with a needle-hole technique is a less invasive procedure that can be performed without tissue grafts, offering a greater cosmetic advantage than open procedures 5.
