The knee is the meeting point of the femur (thigh bone) in the upper leg and the tibia (shinbone) in the lower leg. Goldblatt, J.P.; Richmond, J.C. Anatomy and biomechanics of the knee. The knee joint is a synovial joint. The tibio­ femoral joint is divided into medial and lateral com­ partments. 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. The major classes of sensory receptors that provide afferent feedback contributing to knee stability are mechanoreceptors and nociceptors; where proprioceptors can be considered a sub-classification of mechanoreceptors. Those are the femoral, tibial and common fibular nerves. Numerous bursae, or fluid-filled sacs, help the knee move smoothly. 3) Anterior cruciate ligament (ACL) – lies in the middle of the knee. ; Grey, M.J.

Subscribe to receive issue release notifications and newsletters from MDPI journals, You can make submissions to other journals. The patella(or kneecap, as it is commonly called) is made of bone and sits in front of the knee. 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. Abbreviations: n = nerve, AP = Anterior-posterior, PA = Posterior-anterior. Unable to display preview. Saltzman, B.M. In addition, the semitendinosus acts as a medial rotator of the knee. 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 [. Ligaments join the knee bones and provide stability to the knee: Two C-shaped pieces of cartilage called the medial and lateral menisci act as shock absorbers between the femur and tibia. Bursitis often occurs from overuse or injury. RICE therapy: Rest (or reducing daily activities), Ice, Compression (as with bandage support) and Elevation. The patella. ; Thomée, R. A 7-year study on risks and costs of knee injuries in male and female youth participants in 12 sports. Picture of the Knee. 4. Çabuk, H.; Kuşku Çabuk, F. Mechanoreceptors of the ligaments and tendons around the knee. In all but one of the 41 dissected knees (97%) a distinct ligamentous structure was identified at the anterolateral side of the knee joint connecting the femur with the tibia. The knee anatomy is a complex hinge joint that flexes, extends, and twists slightly from side to side. • Femur • Tibia • Fibula • Patella . ; Goel, V.K. The blood supply of the medial and lateral knee cartilage (menisci) differs. ; Oliver, J.L. The majority of the muscles around the knee that are monoarticular act to primarily mobilise and secondarily stabilise the knee. The knee joint is made up of three bones and a variety of ligaments. All provide stability in a specific direction and play a role in joint proprioception through their cutaneous receptors. ; Snyder-Mackler, L. Controversies in knee rehabilitation: Anterior cruciate ligament injury. The Knee Joint • Poorly constructed in terms of stability - femur round, tibia flat. They are filled with synovial fluid and help in reducing friction between adjacent moving structures, five of which are located at the frontal aspect of the knee, with another four at the lateral side and another five on the medial side of the knee joint. ; Klonk, C.J. Knee joint stability requires the integration of a complex set of anatomical structures and physiological mechanism. ; Moen, S.M. The anatomy and function of the anterior cruciate ligament as determined by clinical and morphological studies. The secondary stabilisers of the knee joint are all the muscles surrounding the knee alongside the hip muscles and the gastrocnemius muscle. Knee Joint Anatomy 1. Johnson, J.S. In the knee joint, the femur articulates with the tibia and the patella. Abulhasan, J.F. Zlotnicki, J.P.; Naendrup, J.-H.; Ferrer, G.A. These bones are connected by supporting and guiding muscles, tendons, ligaments, menisci, the joint capsule, bursae and infrapatellar fat body. Kellis, E.; Mademli, L.; Patikas, D.; Kofotolis, N. Neuromuscular interactions around the knee in children, adults and elderly. ; Craig, E. Knee anatomy: A brief review. The knee is formed by the femur (the thigh bone), the tibia (the shin bone), and the patella (the kneecap). Technol. Sports Med. Diagnostic value of knee arthrometry in the prediction of anterior cruciate ligament strain during landing. The knee maintains stability and control during a variety of loading situations. It is formed by articulations between the patella, femur and tibia. The smaller bone that runs alongside the tibia (fibula) and the kneecap (patella) are the other bones that make the knee joint. Finally, the musculature of the lateral aspect of the knee consists of the iliotibial band and the popliteus muscles. The aim of this report is to review the present knowledge and provide an overview on the structure and function of the knee joint, which will provide basic background knowledge to the subsequent articles in the journal’s Special Issue “The Knee: Structure, Function and Rehabilitation”.

The role of the posterolateral and cruciate ligaments in the stability of the human knee. Solomonow, M.; Baratta, R.; Zhou, B.H. 1). The knee is reinforced by two collateral ligaments, one on the medial side and another on the lateral side, as well as two stronger ligaments (the cruciate ligaments) that prevent excessive anterior, posterior, varus, and valgus displacement of the tibia in relation to the femur. Knee joint anatomy, type of joint, articular surfaces, capsule and synovial membrane, movements, locking and unlocking of knee joint, applied anatomy (SHENG, 2008) The knee consists of 2 joints: the femorotibial joint and the patellofemoral joint.

The receptors generally considered to provide the central nervous system with afferent feedback important for knee stability include Ruffini endings, Pacini corpuscles, free nerve endings, Golgi tendon organs, and muscle spindles (types I and II). The MCL provides stability to the medial aspect of the knee, preventing excessive valgus stress during external rotation of the knee, becoming tight during extension and external rotation, and loose during flexion and internal rotation.
