What is the popliteomeniscal fascicle?
The popliteomeniscal fascicles are. posterolateral meniscocapsular extensions. that blend inferiorly into the popliteus muscu- lotendinous region and allow the tendon to. pass from an intraarticular to an extraarticular.
What is a peripheral meniscus tear?
Central tears are located on the inner side of the meniscus. This is a part of the meniscus without vascular blood supply and therefore not amenable to repair. Peripheral tears are located further on the outside of the meniscus, and these are the types of tears that can sometimes be repaired.
What is Meniscocapsular separation?
Meniscocapsular separation refers to detachment of the meniscus from its capsular attachments. It is an uncommon injury.
What are Meniscofemoral ligaments?
The Posterior meniscofemoral ligament (also known as the ligament of Wrisberg) is a small fibrous band of the knee joint. It attaches to the posterior area of the lateral meniscus and crosses superiorly and medially behind the posterior cruciate ligament to attach to the medial condyle of the femur.
What type of meniscus tears require surgery?
The most common type of tear to the meniscus is a radial tear. This type of tear occurs in the area of the knee that isn’t supplied with blood, so it cannot heal on its own. Surgery may be required if the tear is severe. In the case of a radial tear, the surgeon will trim away the damaged part of the meniscus.
What does a popliteus tear feel like?
Popliteus injury symptoms The main symptom of a Popliteus strain is pain at the back of the knee joint. It can occur gradually through overuse or may result from a sudden twisting, fall or collision. The back of your knee will feel tender when pressing in.
How do you treat a popliteus injury?
The treatment for popliteus tendinopathy includes rest, ice application, elevation, an elastic wrap, physical therapy, and nonsteroidal anti-inflammatory medication for pain, such as aspirin or ibuprofen. Additional treatment for popliteus tendinopathy may include oral corticosteroids or corticosteroid injections.
What is the purpose of the Meniscofemoral ligament?
» The meniscofemoral ligaments (MFLs), consisting of the anterior MFL (ligament of Humphrey) and the posterior MFL (ligament of Wrisberg), as well as the osseous attachment of the meniscal root, stabilize the lateral meniscus, enabling appropriate load transmission and maintenance of contact forces within the lateral …
Why are popliteomeniscal fascicle tears difficult to diagnose?
Yet, isolated popliteomeniscal fascicle tears are often difficult to recognize and diagnose due to the vague symptoms and of- ten-normal magnetic resonance imaging (MRI) and physical examination findings.2,3These isolated injuries are often misdi – agnosed and mistreated, which often leads to delayed surgical treatment.
Where are the popliteomeniscal fascicles located in the knee?
There are 3 popliteomeniscal fascicles (anteroinferior, pos- terosuperior, and posteroinferior),12,13,15 which combined with the popliteus tendon form a peripheral hooplike attachment to the lateral meniscus at the popliteal hiatus of the knee.
How are fascicles attached to the lateral meniscus?
The popliteomeniscal fas- cicles are composed of 3 dis- tinct fasciculi, anteroinferior, posterosuperior, and posteroin- ferior, that attach to the lateral meniscus at the popliteal hiatus (Figure 1).5Sussmann et al6 suggested that, embryologically, the fascicles allow vascular sup- ply to the lateral meniscus.
How is iohexol used to treat popliteomeniscal fascicles?
Approximately 55–60 mL of a solution containing 1 mL of gadopentetate dimeglumine (Magnevist, Bayer Schering Pharma) diluted in 250 mL of equal parts saline solution and iohexol (Omnipaque 350, GE Healthcare) was injected into each knee joint via a lateral suprapatellar approach with an 18-gauge needle.
