What is the patellar retinaculum?
The medial patellar retinaculum is a strand of connective tissue, reinforcement of the joint capsule, detached from the regional fascia between the tendon of the quadriceps muscle, the medial border of the patella, the medial femoral condyle and the trochlea of tibia (and tibial tuberosity in horses and cattle).
What is the ligamentum patellae?
The patellar ligament is the central portion of the common tendon of the Quadriceps femoris, which is continued from the patella to the tuberosity of the tibia. It is a strong, flat, ligamentous band, about 8 cm.
What is medial and lateral patellar Retinaculum?
The results of the cadaveric study indicate that medial patellar retinaculum prevents LPD and lateral patellar tilt. Lateral patellar retinaculum provides a retractive force to prevent medial patellar tilt.
Where does the lateral retinaculum attach?
patella
Insertion: The anterior fibres insert into the lateral retinaculum of the patella and the patellar ligament. The posterior fibres insert via the iliotibial tract at the lateral tubercle of the tibia.
What muscle inserts on the tibial tuberosity?
The quadriceps femoris is a four-headed muscle that inserts onto the tibial tuberosity. It extends the knee, and one head (rectus femoris) flexes the hip.
Is retinaculum a ligament?
Posteriorly the fibers weave together with the fibers of the medial collateral ligament. Like all other tendons, the medial patellar retinaculum is made of dense regular connective tissue.
How long does it take Retinaculum to heal?
Recovery from surgery requires a moderately long period, usually in the order of 2-6 weeks of immobilization, in order to allow the retinaculum and any bony procedures to heal. This is followed by four to six weeks of fairly graduated and intensive rehabilitation.
Can Retinaculum repair itself?
Superior peroneal retinaculum tears are often mistaken for lateral ankle instability. These tears often do not heal readily by themselves and must be identified so that proper treatment can begin.
What are the different causes of patellar ligament pain?
Patellar tendonitis comes from repetitive stress on the knee, most often from overuse in sports or exercise. The repetitive stress on the knee creates tiny tears in the tendon that, over time, inflame and weaken the tendon. Contributing factors can be:
What is medial femoral patellar ligament?
Medial patellofemoral ligament is a band of tissue that extends from the femoral medial epicondyle to the superior aspect of the patella.
What is a medial ligament tear?
An MCL tear or Medial collateral ligament tear is a physical injury sustained on the knee, dealing critical damage to one of the vital components of the joint in the knee that offers support and stability to the entire limb and body. The MCL is one of the four main ligaments of the knee, along with the anterior cruciate ligament,…
