O - Oblique popliteal Oblique popliteal ligament Is an oblique expansion of the semimembranosus tendon and passes upward obliquely across the posterior surface of the knee joint from the medial condyle of the tibia. Resists hyperextension of the leg and lateral rotation during the final phase of extension Medial collateral ligament Injury of the knee (MCL Tear) are the most common ligament injuries of the knee and are frequently associated with ACL tears. They are cause by either a direct blow (more severe tear) or a non-contact injury (less severe). Treatment is usually bracing unless there is gross varus instability in which case repair or reconstruction is performed

The posterior oblique ligament arises from several arms of the superficial MCL, both superiorly and inferiorly, as well as from the posterior aspect of the deep MCL (therefore both layers 2 and 3 contribute to it). The posterior oblique ligament then extends from its posteromedial position to contribute to the oblique popliteal ligament, which. Oblique Popliteal Ligament. The OPL arises from the capsular arm of the POL and lateral expansion of the semimembranosus. Laterally, the OPL attaches to the osseous or cartilaginous fabella, the meniscofemoral portion of the posterolateral joint capsule, and the plantaris muscle In this video we will study about the Arcuate Popliteal and Oblique Popliteal Ligament of Knee Joint in detail.

The oblique popliteal ligament is an expansion of the tendon of the semimembranosus. It arises from the medial tibial condyle and passes toward the lateral femoral condyle, where it blends in with the rest of the joint capsule and. Then, there's the oblique popliteal ligament, which is an expansion of the tendon of the semimembranosus that reinforces the joint capsule posteriorly. The ligament arises posterior to the medial tibial condyle and passes superolaterally toward the lateral femoral condyle, blending with the central part of the posterior aspect of the joint. ligament, the posterior capsule, and an inferolateral connection with the oblique popliteal ligament [14, 16]. A variant of the posterior meniscofemoral ligament of Wris-berg has been reported in which the origin is the medial aponeurosis of the popliteus mus-culotendinous region rather than the posteri-or horn of the lateral meniscus [14] a second part that fuses with the popliteal fascia and a third part that becomes the oblique popliteal ligament. Another important feature of semimembranosus is that its lateral border forms the superomedial wall of the popliteal fossa

Introduction . This study investigated the importance of the oblique popliteal ligament (OPL), and challenges its alleged ligament status. The currently named OPL is indigenous to the distal semimembranosus (SMT); therefore, by definition is not a ligament inserting from bone to bone. Clinically, a muscle-tendon unit is different then a ligament regarding proprioception and surgery. <i. patellar Ligament Att: lateral femur, over condyles to posterior head of fibula Mov: limits extension, strengthens the fibrous joint capsule posteriorly Com: An expansion of the tendon of semimembranosus muscle : Oblique Popliteal Lig: Att: Medial epincondyle of femur to medial condyle and shaft of tibi The oblique popliteal ligament arises from the semimembranosus muscle-tendon complex and capsular arm of the POL and extends in an oblique direction to the tendon of the lateral head of the gastrocnemius muscle and plantaris muscle. There is also anterior extension of the injury with tearing of the medial patellofemoral ligament and edema. Oblique Popliteal Ligament • Strengthens the posterior portion of the capsule and prevents extreme lateral rotation • It is an expansion from the semimembranosus tendon close to its insertion to the tibia • Branch from the posterior division of the obturator nerve, pierces the ligament, supplies cruciates and articular twig to knee.

Besides halting leg extension and preventing hyperextension, these collateral ligaments prevent the leg from moving laterally and medially at the knee. The oblique popliteal ligament (back of the knee) crosses the posterior aspect of the capsule. Actually it is a part of the tendon of the semimembranosus muscle that fuses with the joint. 43Knee Joint and Popliteal Fossa. The knee joint is a synovial hinge-type joint between the femur and tibia; its range of movement is limited primarily to flexion and extension, but some rotation is possible. The superior part of the knee joint is formed by the condyles of the femur. These enlarged bony prominences transfer weight to the. After piercing roof of popliteal fossa supply skin of popliteal fossa and upper part of back of leg. 9) Descending genicular branch of posterior division of obturator nerve It is a branch of posterior division of obturator nerve.

Since posterior structures, including the PMC and PLC, become taut with knee extension, these structures have a critical role in stabilizing the knee in an extension position. Furthermore, the posterior capsule and oblique popliteal ligament (OPL) are quite strong structures that contribute to the stability of knee extension . Therefore, these. The ligaments of the knee include the patellar ligament, fibular/lateral collateral ligament (LCL), tibial/medial collateral ligament (MCL), oblique popliteal ligament, arcuate popliteal ligament, anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), transverse ligament, posterior meniscofemoral ligament, and the coronary.

The popliteal ligament is one of two ligaments found in the leg behind the knee joint. Both extracapsular ligaments, meaning that they are located to the outside of the joint capsule, the oblique popliteal ligament and arcuate popliteal ligament link the bones of the knee on their posterior sides The oblique popliteal is broad and flat and is attached to the femur and the tibia. The arcuate popliteal is shaped like the letter y and is attached to the fibula with branches extending to the femur and tibia. Some ligament injuries may heal on their own with ice, rest and elevation to reduce pain and inflammation OBLIQUE POPLITEAL Upward extension of semimembranosus tendon. Limits extension & thus aids knee locking Medial MEDIAL COLLATERAL Broad, long, thick, strong Attached to capsule & medial meniscus Limits full extension & thus aids locking NOTE Lateral Iliotibial tract LATERAL COLLATERAL Thick, cordlike. Not attached to joint structures fibers to the oblique popliteal ligament; none have hypoth-esized that this structure is itself a tendon [1-31]. A macro-analysis using deep dissection of the posterior knee revealed that the OPL's distal (medial) attachment originated from the SMTU in 100% of the knees. This provided evidence i The arcuate popliteal ligament is a thickening of the capsule arching over the exiting popliteus. The oblique popliteal ligament is a capsular thickening that extends from the semimembranosus muscle and runs parallel to the popliteus.
