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.
Is the MPFL the same as the medial retinaculum?
It is located superior and anterior to the medial collateral ligament and is part of the medial patellar retinaculum and the intermediate medial capsular layer 1-4 and it forms the medial patellofemoral complex together with the medial quadriceps tendon femoral ligament 5.
Is retinaculum a ligament or tendon?
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).
Do you need surgery for a torn MPFL?
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 knee Retinaculum?
The medial patellar retinaculum is a tendon of the knee that crosses the knee joint on the medial side of the patella. The medial patellar retinaculum is the branch of the tendon of insertion of the quadriceps femoris that crosses the knee on the medial side of the patella.
Can you walk with a torn patella tendon?
Walking after a patellar tendon tear is possible, however, many patients will notice significant knee instability as well as severe pain.
What ligament keeps your kneecap in place?
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.
What ligaments hold the kneecap in place?
A ligament called the medial patellofemoral ligament, or MPFL, holds it in place. The MPFL is located on the inside of the knee and connects the kneecap to the femur or inner thighbone, helping to keep the kneecap centered in the bone groove.
What is medial Retinaculum?
The medial patellar retinaculum is a tendon of the knee that crosses the knee joint on the medial side of the patella. It plays important roles in the formation of the fibrous capsule of the knee and in the extension of the knee joint.
Where is the patellar retinaculum located in the knee?
From the femoral region, they extend obliquely across the medial side of the knee’s anterior, between the medial edge of the patella and the medial (tibial) collateral ligament (MCL). At its inferior end, the medial patellar retinaculum inserts into the medial epicondyle of the tibia.
What does it mean to have a medial retinaculum?
“Medial” means “extending toward the middle.” The knee has both dynamic and passive stabilizers; the medial retinaculum is a passive stabilizer of the knee joint. The two types of stabilizers work together to control patellar tracking — the movement of the bone of the kneecap.
Where is the medial collateral ligament in the knee?
It is one of the most common knee injuries and results mostly from a valgus force on the knee. The medial collateral ligament is a big ligament on the medial side of the knee. For more clinically relevant anatomy of the knee click here.
Which is the tendon that crosses the knee joint?
Medial Patellar Retinaculum. The medial patellar retinaculum is a tendon of the knee that crosses the knee joint on the medial side of the patella.
