https://youtu.be/j2fDfCxn27c https://youtu.be/kEuMzUrHD0M The posterior meniscofemoral ligament in the knee connects the medial femoral condyle to the posterior horn of the lateral meniscus. It runs posterior to the posterior cruciate ligament (PCL) and attaches above the PCL. This ligament is positioned more posteriorly compared to the anterior meniscofemoral ligament, which attaches below the ..

https://youtu.be/CjYENTgOT3Y https://youtu.be/kEuMzUrHD0M "🧐 Deep Dive into the Meniscofemoral Ligament (MFL) Anatomy! ✨ The MFL, a critical component of the knee, originates from the posterior horn of the lateral meniscus and inserts onto the lateral aspect of the posterior medial femoral condyle. It plays a key role in the stability and function of the knee joint. 🔍 Let's break it down: 1️⃣ Th..

https://youtu.be/-lNJo4zWnqs https://youtu.be/kEuMzUrHD0M PRLM has two attachment sites of the posterior slope of the lateral tubercle (1st coronal image) and intertubercular region (other coronal images). - major component: intertubercular area, anterior extension into medial tubercle along the intertubercular crest, just posteromedial to tibial attachment of anterior cruciate ligament (; ACL) ..

https://youtu.be/GvR9ULGrDOw https://youtu.be/kEuMzUrHD0M Category Description Insertion Points - Inserts along the downward slope of the intercondylar fossa, anterior to the posterior cruciate ligament. - Extends from the tibial attachment point to just lateral from the articular cartilage inflection point of the medial tibial plateau. - Commences just lateral to the apex of the medial tibial p..

https://youtu.be/w2QemJqJBfsTitle: Unraveling the Complexities of the Lateral Meniscus and ACL on MRI https://youtu.be/kEuMzUrHD0M 🔍 Deep Dive into Anatomy and Injury: the intricate relationship between the anterior root of the lateral meniscus (LM) and the anterior cruciate ligament (ACL) in the knee, as revealed by MRI. Unique Structure: The anterior root of the LM is distinct with its fan-sha..

https://youtu.be/dECIy2gvacM https://youtu.be/kEuMzUrHD0M The medial meniscus has an anterior root that attaches to the area in front of the tibial attachment of the ACL, specifically in the intercondylar fossa of the tibia. Additionally, the posterior fibers of the anterior horn of the medial meniscus connect to the transverse ligament. This anterior root can vary in attachment, with most peopl..

Medial Patellar Retinacular Structures✓ Medial patellofemoral ligament (MPFL): (most important component) ✓ Medial patellotibial ligament (MPTL) ✓ Medial patellomeniscal ligament (MPML) ✓ Medial quadriceps tendon femoral ligament (MQTFL) Composition of the MPFL A stronger transverse band and a more variable, weaker oblique decussation. Two components: Transverse Component (tMPFL) Originates more..

Dislocation of a polyethylene insert Mechanism of Dislocation (DPI in TKA) Proposed Cause Atraumatic nature No clear cause identified Traumatic mechanism (insert dislocation) Repeated posteriorly directed compressive force on the polyethylene insert from the femur Biomechanical basis for dislocation During knee flexion, femoral tibial contact moves posteriorly, leading to anterior lift-off of th..

Polyethylene Wear Polyethylene components used in total knee arthroplasty (TKA) can experience wear on the articular surfaces due to abrasion and fatigue This wear generates polyethylene debris, which triggers an inflammatory response. Over time, this response can lead to osteolysis and loosening. Radiographic Findings of Polyethylene Wear Progressive joint space narrowing Sequential radiographs..
