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..

https://youtu.be/wmpIaimU2gE The anatomic variation of the anterolateral fixation of the lateral meniscus to the ITB, which we have termed the “accessory iliotibial band–meniscal ligament” or “AIML.” An AIML was present in 13.3% of all patients (136/1019). AJR Am J Roentgenol. 2019 Oct;213(4):912-917. Although the attachments of the anterior and posterior horn are relatively consistent, the ante..

https://youtube.com/shorts/EXt4aC9NvpUzA Acute gout is intensely inflammatory, presenting as a relatively sudden onset severe pain in a joint associated with swelling, warmth, and redness that may extend beyond the joint, mimicking cellulitis. The earliest episode of acute gout are usually mono-articular and usually affect, in decreasing order of frequency, the first metatarsophalangeal joint (‘..
