What is the Popliteofibular ligament?
The popliteofibular ligament (PFL) belongs to the lateral supporting structures of the knee and is one of the three primary stabilizers of the posterolateral corner 1-6.
What structures make up the arcuate complex?
Arcuate ligamentous complex of the knee….Radiographic features
- biceps femoris tendon.
- fibular collateral ligament.
- popliteus tendon.
- popliteus musculotendinous complex including: popliteofibular ligament. fabellofibular ligament. arcuate ligament.
What is PLC ligament?
The Posterolateral Corner (PLC) of the knee refers to the ligaments and tendons at the back (posterior) and outside (lateral) part of the knee.
What makes up the LCL complex?
The LCL is a cord-like structure of the arcuate ligament complex, together with the biceps femoris tendon, popliteus muscle and tendon, popliteal meniscal and popliteal fibular ligaments, oblique popliteal, arcuate and fabellofibular ligaments and lateral gastrocnemius muscle.
What is the function of the arcuate and popliteal ligaments of the knee?
The arcuate popliteal ligament reinforces the posterolateral part of the joint capsule, and together with the oblique popliteal ligament, prevents overextension of the knee joint.
Where does the arcuate ligament attach?
The arcuate ligament arises from the fibular styloid with lateral limb attachment to the femur and popliteus tendon, and medial limb attachment to the posterior horn of the lateral meniscus of the knee.
What is the function of the arcuate ligament?
The posterior cruciate ligament and the arcuate ligament have predominant role for the posterolateral stability of the knee. The functional restoration of these ligaments is an important part of the surgical treatment of posterolateral ligamentous injuries.
What structures make up the PLC?
The three major static stabilizers of the PLC are the fibular (lateral) collateral ligament (FCL), the popliteus tendon (PLT) and the popliteofibular ligament (PFL)(9).
What does the LCL attach to?
The lateral collateral ligament is a thin band of tissue running along the outside of the knee. It connects the thighbone (femur) to the fibula, which is the small bone of the lower leg that runs down the side of the knee and connects to the ankle.
Where does the LCL insert?
Origin and Insertion: Originating 1.4 mm proximal and 3.1 mm posterior to the lateral epicondyle of the femur, the LCL runs approximately 0.69 mm along the lateral portion of the knee. It inserts 28.4 mm distal to the fibular styloid tip, where it there inhabits nearly 38% of the fibular head.
Where is the LCL ligament located?
The lateral collateral ligament (LCL) is on the outer side of your knee and runs from the top part of the fibula (the bone on the outside of the lower leg) to the outside part of the lower thigh bone. The ligament helps keep the outer side of your knee joint stable.
What passes under the medial arcuate ligament?
The medial arcuate ligament (also medial lumbocostal arch and internal arcuate ligament) is a tendinous fascia that arches over the psoas major muscle as it passes posterior the diaphragm. The diaphragm.
Where is your LCL located?
What does LCL connect?
About the lateral collateral ligament The lateral collateral ligament is a thin band of tissue running along the outside of the knee. It connects the thighbone (femur) to the fibula, which is the small bone of the lower leg that runs down the side of the knee and connects to the ankle.
