The document discusses the anatomy of the knee, including its main components that allow for movement with stability and control. The knee acts as a hinge joint between the femur and tibia bones and contains ligaments that stabilize it both inside and outside the joint. It is able to absorb shock through meniscal structures and enable movement through opposing muscle groups like the quads and hamstrings working in counter-force with one another. Injury can disrupt this anatomy by abnormally tearing its stabilizing structures.

The knee joint
The knee joint is the largest and most complicated joint in the body, formed by the fusion of the femur, tibia, and patella bones. It contains several ligaments like the anterior and posterior cruciate ligaments that provide stability, as well as menisci that act as shock absorbers. Injuries to the ligaments and menisci are common and can be diagnosed using clinical tests, with treatments including physical therapy, surgery such as arthroscopy, or in severe cases, knee replacement surgery.
01. knee anatomy
The knee joint is actually two joints: the tibiofemoral joint and the patellofemoral joint. It allows for flexion and extension as the primary motions. The knee is supported by ligaments like the ACL, PCL, and collateral ligaments, as well as menisci that absorb shock and increase stability. Muscles like the quadriceps and hamstrings are responsible for knee flexion and extension. The anatomy of nerves and blood vessels around the knee also make certain injuries more common.
Anatomy of the knee joint
The knee joint is the largest and most complicated joint in the body. It consists of three joints: the medial and lateral tibiofemoral joints and the patellofemoral joint. The knee joint is stabilized by numerous ligaments including the anterior and posterior cruciate ligaments, the medial and lateral collateral ligaments, and the transverse ligament. It also contains two menisci that help distribute weight forces and provide shock absorption. The knee is supplied by branches from the femoral, tibial and common peroneal nerves and receives its blood supply from the femoral, popliteal and genicular arteries.
Knee joint
it concentrates mainly on the movements of the knee joint and locking and unlocking of knee joint. it is more easy and simple and complete
Ankle joint
The ankle joint is a uniaxial synovial hinge joint formed between the distal end of the tibia, lateral malleolus of the fibula, and talus bone. It is stabilized by strong ligaments including the deltoid ligament medially and three lateral ligaments. The joint allows for dorsiflexion and plantar flexion movement about its axis and is supplied by the posterior and anterior tibial arteries and nerves. Common injuries include ankle sprains from excessive inversion or eversion stretching the lateral or deltoid ligaments, respectively.
Anatomy and clinical importance of knee joint
The knee joint is comprised of the articulating surfaces of the femur and tibia bones, as well as the patella. It is surrounded by ligaments such as the ACL and PCL, and contains menisci that act as shock absorbers. Common clinical issues involving the knee include meniscal tears from twisting injuries, ligament sprains from excessive valgus or varus forces, and osteoarthritis over time. Special tests like Lachman, McMurray, and varus/valgus stress exams help evaluate specific ligament and meniscal injuries.
Surgical anatomy of knee joint
The knee joint is the largest and most complicated joint in the body. It allows for both flexion and extension as well as some rotational movement. The knee joint is formed by the articulation of the femoral condyles and tibial plateaus. It contains two menisci that act as shock absorbers and help with joint lubrication. Stability is provided by ligaments like the ACL, PCL, MCL and LCL as well as dynamic stabilizers like the quadriceps muscles. Proper functioning of the knee relies on the intricate interplay of its bony architecture and soft tissue structures.

Anatomy of anterior_cruciate_ligament_by- dr. armaan singh
The anterior cruciate ligament (ACL) originates on the posterior medial femoral condyle and inserts on the anterior tibia. It consists of anteromedial and posterolateral bundles that twist during knee flexion. The ACL prevents anterior tibial translation and internal rotation. Injury is common in sports involving pivoting. Females have a higher risk due to narrower intercondylar notches. The posterior cruciate ligament (PCL) is the strongest ligament and prevents posterior tibial translation. Both cruciates receive blood supply from the middle genicular artery and have proprioceptive mechanoreceptors.

Knee Injuries
The knee joint is complex and vulnerable to injury due to high stress. Common acute injuries include patellar dislocation, meniscal tears, and ligament sprains. Patellar dislocation occurs when the patella is displaced from its normal position, often due to direct impact or forceful quadriceps contraction. Meniscal tears are caused by the menisci receiving poor blood supply in their centers, making tears difficult to heal. Ligament sprains range in severity from minor fiber tears to complete ruptures. Understanding the knee's anatomy is important for diagnosing and treating these injuries.
1. biomechanics of the knee joint basics
This document provides an overview of the biomechanics of the knee complex. It describes the knee as the largest and most complex joint, consisting of the tibiofemoral and patellofemoral joints. The knee functions to flex and extend the leg, support body weight, and facilitate locomotion. Key components include the articular surfaces, menisci, capsule, collateral and cruciate ligaments, muscles, bursae, and plicae. The document outlines the roles and mechanics of each of these structures, as well as common injuries associated with the knee.
Ligaments of ankle joint (Ankle complex)
This document describes the ligaments of the ankle joint. It notes that the ankle joint is stabilized by a capsule attached above and below the tibia, fibula, and talus. The main ligaments discussed are the anterior/posterior tibiofibular ligaments, crural interosseous ligament, medial collateral (deltoid) ligament, and lateral collateral ligament complex. The medial collateral ligament controls eversion while the lateral collateral ligament controls inversion and prevents subluxation. Injuries to the ligaments, particularly the lateral ligaments, are common ankle injuries.
Knee joint anatomy final ppt
The document provides an overview of knee joint anatomy, describing the osseous structures (femur, tibia, patella), extra-articular structures (capsule, ligaments, muscles), and intra-articular structures (menisci, cruciate ligaments). It details the anatomy of the medial and lateral menisci, including their shape, composition, attachments, and functions in load bearing, stability, and joint lubrication. The cruciate ligaments and complex anatomy of the medial and lateral aspects of the knee are also summarized.
Biomechanics of knee complex 2
The menisci of the knee play several important roles. They improve tibiofemoral congruence, distribute weight-bearing forces to reduce friction and act as shock absorbers. The medial meniscus is C-shaped while the lateral is four-fifths circular. Both are thicker peripherally and thinner centrally. The medial meniscus covers less of the tibial plateau and has greater ligamentous restraints. The menisci receive nutrition through blood vessels in the periphery but rely on synovial fluid diffusion centrally. They are well innervated in the periphery to detect pain and proprioception.
Knee joint
The knee joint is complex with three bones - the femur, tibia, and patella - forming two joints, the patellofemoral and tibiofemoral joints. The knee allows for flexion/extension in the sagittal plane as well as medial/lateral rotation in the transverse plane. Cruciate ligaments like the ACL and PCL provide stability while menisci absorb shock and increase joint congruence. Proper biomechanics and alignment of the femur and tibia distribute weight forces evenly across the knee. Injuries require clinicians to have extensive knowledge of the knee's intricate nature.
Biomechanics of knee complex 5 bursae
This document discusses the bursae of the knee complex. It notes that numerous bursae help prevent friction between ligaments, muscles, and bones during movement of the knee. Specifically, it describes the locations and functions of the suprapatellar, subpopliteal, and gastrocnemius bursae which connect to the synovial joint capsule. The positions of flexion, extension, and semiflexion of the knee affect the pressure on these bursae and distribution of synovial fluid within the joint. Additional bursae around the knee, such as the prepatellar and infrapatellar bursae, reduce friction and allow skin movement over the patella.
Knee Joint Anatomy
The knee joint is the largest and most complex joint in the body. It consists of three joints: the medial and lateral condylar joints between the femur and tibia, and the patellofemoral joint between the femur and patella. Key structures include the cruciate ligaments which provide stability, menisci which absorb shock and distribute force, and synovial membrane which lines the joint space. The document provides detailed descriptions of the articular surfaces, ligaments, bursae, and other anatomical structures that make up the knee joint.
Knee joint
The knee joint is the largest and most complex joint in the body. It is a modified hinge joint that allows flexion, extension, and some rotation. The knee joint is composed of three articulations: the medial and lateral tibiofemoral joints between the femur and tibia, and the patellofemoral joint between the femur and patella. The knee joint is supported by ligaments such as the anterior and posterior cruciate ligaments, as well as menisci that cushion the joint surfaces.
Knee joint
The knee joint is the largest synovial joint in the body. It is composed of three bones: the femur, tibia, and patella. The knee joint has two articulations: the tibiofemoral joint between the femur and tibia, and the patellofemoral joint between the patella and femur. The knee joint is a compound synovial joint, with the tibiofemoral joint being a hinge type and the patellofemoral joint being a plane type. The knee joint is surrounded by ligaments such as the ACL and PCL, and contains a synovial fluid within its capsule. It also contains menisci that act as cushions and increase stability.
Synovial joint
This document discusses the classification of synovial joints based on the shape of their adjoining articular surfaces. It describes the six main types of synovial joints: plane, pivot, hinge, condylar, ellipsoid, saddle, and ball-and-socket. For each joint type, it provides details on the articular surface shape, typical movements allowed, and examples of joints that fall into that classification.
Anatomy of the knee joint
The knee joint is the largest joint in the body. It has three articulations: the femorotibial articulations on the lateral and medial sides, and the femoropatellar articulation. The knee joint allows for flexion and extension movements and contains articular surfaces on the femoral condyles that interact with the tibia. Ligaments such as the cruciate ligaments and menisci provide stability to the joint, which is surrounded by a joint capsule lined with synovial membrane. Muscles like the quadriceps and hamstrings are responsible for extension and flexion of the knee.
Knee joint By Dr Shyam Sunder Sharma
The knee joint is made up of two joints - the patellofemoral joint and the tibiofemoral joint. It is a complex hinge joint that lacks inherent stability and relies on surrounding soft tissues like ligaments, muscles, and menisci. The menisci absorb shock, increase congruency, and decrease pressure in the joint. Major ligaments include the ACL, PCL, MCL, and LCL. Common injuries involve tears to these ligaments from forces of valgus, varus, twisting, or anterior/posterior displacement. Other common knee conditions include meniscal tears, patellofemoral pain syndrome, tendinitis, bursitis, and osteochondromatosis. The

The Electrocardiogram - Physiologic Principles
These lecture slides, by Dr Sidra Arshad, offer a quick overview of the physiological basis of a normal electrocardiogram.
Learning objectives:
1. Define an electrocardiogram (ECG) and electrocardiography
2. Describe how dipoles generated by the heart produce the waveforms of the ECG
3. Describe the components of a normal electrocardiogram of a typical bipolar lead (limb II)
4. Differentiate between intervals and segments
5. Enlist some common indications for obtaining an ECG
6. Describe the flow of current around the heart during the cardiac cycle
7. Discuss the placement and polarity of the leads of electrocardiograph
8. Describe the normal electrocardiograms recorded from the limb leads and explain the physiological basis of the different records that are obtained
9. Define mean electrical vector (axis) of the heart and give the normal range
10. Define the mean QRS vector
11. Describe the axes of leads (hexagonal reference system)
12. Comprehend the vectorial analysis of the normal ECG
13. Determine the mean electrical axis of the ventricular QRS and appreciate the mean axis deviation
14. Explain the concepts of current of injury, J point, and their significance

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
