Other ligaments, such as the transverse, arcuate popliteal, oblique popliteal, anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), lateral collateral ligament (LCL), and popliteofibular ligament all act as knee stabilisers. ; Bakhsh, M.M. Next. The vascular supply to the knee consists of a network of many arteries. The posterior aspect of the knee consists of the biceps femoris (biarticular), semimembranosus (monoarticular), and semitendinosus (monoarticular), which form the hamstring group of muscles which function as knee flexors. This is achieved through involuntary work as muscles are connected to tendons in order to be dynamically reinforced and contracted during motion, which is when ligaments are at risk and need the assistance provided through muscular force. Hirschmann, M.; Müller, W. Complex function of the knee joint: The current understanding of the knee. The knee is formed by the femur (the thigh bone), the tibia (the shin bone), and the patella (the kneecap). A comprehensive understanding of the anatomy and physiology of the structures of the knee is necessary for accurate diagnoses and informed decisions regarding treatment plans. The knee joint is the largest joint in the body and connects the thigh with the lower leg. When identifying the source of knee pain or dysfunction, it’s critical to begin with a strong foundational knowledge of knee anatomy and the functions of the joint’s components. See knee joint stock video clips. Fremerey, R.W. The knee joint is made up of three bones and a variety of ligaments. Sensory effects of pulling or vibrating exposed tendons in man. J Sports Traumatol 4: 171 Google Scholar. Joint Anatomy and Basic Biomechanics OUTLINE 3 From: Harmony Medical. Two round knobs called femoral condyles are found on the end of the femur. Numerous bursae, or fluid-filled sacs, help the knee move smoothly. - It consists of 3 Joints: 1) Medial Condylar Joint : Between the medial condyle “of the femur” & the medial condyle “of the tibia” . ; Morscher, M.A. Search for "knee joint" in these categories. ; Oliver, J.L.

Knee joint anatomy, type of joint, articular surfaces, capsule and synovial membrane, movements, locking and unlocking of knee joint, applied anatomy The knee joint is a synovial joint this means it contains a fluid that lubricates it. 1. Cinar-Medeni, O.; Baltaci, G.; Bayramlar, K.; Yanmis, I. Loës, M.; Dahlstedt, L.J. Palmieri-Smith, R.M. Lansky, D.; Nwachukwu, B.U. Furthermore, the lateral menisci are much more mobile than are the medial menisci, and this is reflected by the higher rate of medial side injuries [, Sensory receptors are classified either by the type of stimulus to which they respond (e.g., mechanoreceptors, nociceptors, chemoreceptors, etc.) Bursitis often occurs from overuse or injury. Orthopaedic Basic Science: Biology and Biomechanics of the Musculoskeletal System. or by their location (e.g., exteroceptors, interoceptors, or proprioceptors). It is responsible for weight bearing and movement. Finally, the musculature of the lateral aspect of the knee consists of the iliotibial band and the popliteus muscles. Surgeons performing reconstructions in patients with these injuries must have a complete understanding of the normal anatomy and biomechanics of the knee to optimize the timing of surgery, the order of ligamentous reconstruction, and the anatomic placement of grafts. Pacinian corpuscles are sensitive to the micro-vibrations that occur during knee movement and, in the cat, respond transiently to joint movement in any direction [, These proprioceptive fibres, together with the ligaments and muscles, combine to create reflex arcs that play a vital role in knee stability [. Knee X-ray: A plain X-ray film of the knee is typically the best initial imaging test for most knee conditions. A common site of bursitis is at the deep infrapatellar bursa due to its vital role in preventing friction between the patellar tendon and the tibia. Please let us know what you think of our products and services. ; Bach, B.R. Abulhasan, J.F. The structure was easily distinguishable from the thinner joint capsule lying anterior to it (Fig. The patella. The knee joint is a hinge type synovial joint, which mainly allows for flexion and extension (and a small degree of medial and lateral rotation). Falls associated with knee instability in people with knee osteoarthritis: Biomechanical risk factors and pain. Core stability, knee muscle strength, and anterior translation are correlated with postural stability in anterior cruciate ligament-reconstructed patients. Bauer, M.; Feeley, B.T. These include the iliotibial tract syndrome, the anserine syndrome, bursitis of the medial collateral ligament, Baker's cyst, popliteus tendon tenosynovitis and bursitis of the deep infrapatellar bursa. The patella(or kneecap, as it is commonly called) is made of bone and sits in front of the knee. The epidemiology of knee injuries in iranian male professional soccer players. This article provides a basis for understanding the anatomy involved in knee disorders and was directed toward structures of clinical importance. ; Craig, E. Knee anatomy: A brief review.

Characteristics of knee joint receptors in the cat. Schutte, M.J.; Dabezies, E.; Zimny, M.; Happel, L. Neural anatomy of the human anterior cruciate ligament. The soleus muscle also resists anterior translation of the knee. The medial musculature of the knee consists of the sartorius and gracilis muscles, which both aid in knee flexion. The lateral menisci are much more mobile than the medial menisci, and this is reflected by the higher rate of medial side injuries [, The knee has four bursae, which are fluid-filled cavities located at tissue sites that facilitate movement of the tendons and skin over the joint. The knee joint is a synovial joint. The blood supply of the medial and lateral knee cartilage (menisci) differs. The patella is a flat, triangular bone, situated on the front of . 3.
