What is medial plication of knee?

What is medial plication of knee?

The medial patellofemoral ligament, which is part of the medial retinaculum, is the main injured structure especially regarding normal knee alignment. Therefore, medial retinacular plication, a proximal realignment correction technique, can directly address the main pathology of patellar instability.

What is medial patellar?

The medial patellar retinaculum is a tendon of the knee that crosses the knee joint on the medial side of the patella. Most of the fibers of the medial patellar retinaculum originate in the medial femoral region from the vastus medialis muscle, just superior to the patella.

Where is the medial patellar?

knee
The medial patellar ligament is located in the second layer of the knee.

What is a torn medial patellar retinaculum?

The MPFL keeps the patella (kneecap) centered, such that it glides properly during leg movement. The MPFL is located on the inner side of the knee and connects the patella to the femur (thighbone). An injury, such as a sprain or tear, to this ligament often occurs because of a forceful, traumatic patella dislocation.

How do I know if I tore my Mpfl?

Common signs and symptoms that may occur with an MPFL injury include:

1. Feeling the knee “give way” or “buckle” during activity.
2. Feeling like the kneecap is sliding out to the side during knee movement.
3. Swelling of the knee after activity.
4. Restricted joint movement (range of motion).
5. Pain when moving the knee.

What is Mpfl knee?

What is the medial patellofemoral ligament (MPFL)? The medial patellofemoral ligament is a part of the complex network of soft tissues that stabilize the knee. The MPFL attaches the inside part of the patella (kneecap) to the long bone of the thigh, also called the femur.

Does medial Retinaculum tear require surgery?

Most first time MPFL injuries can be treated non-surgically with NSAIDs and immobilization. It’s then followed by physical therapy to strengthen the muscles around the knee. Your physician may recommend surgery if the injury is more severe, or if there are small pieces of detached bone or cartilage in the knee.

What is medial patellar luxation in dogs?

Medial patella luxation (MPL) is a common cause of orthopedic lameness in both small and large breed dogs. In the simplest terms this condition is when the patella, or “knee cap”, slips in and out of its natural position.

What is the main function of the patella?

The patella rides in the tendon of the quadriceps femoris—the largest muscle of the thigh and the primary extensor of the knee. The patella functions to protect the knee joint, to lengthen the lever arm of the quadriceps femoris, and to increase the area of contact between the patellar ligament and the femur.

Where does the medial patellar Retinaculum attach?

It inserts onto the medial aspect of the patellar ligament, patella and quadriceps tendon. From this insertion, it extends posteromedially to blend with the medial margin of the knee capsule and inferior surface of the medial tibial condyle.

What is the function of the Retinaculum?

A retinaculum (plural retinacula) is a band of thickened deep fascia around tendons that holds them in place. It is not part of any muscle. Its function is mostly to stabilize a tendon. The term retinaculum is New Latin, derived from the Latin verb retinere (to retain).
