Articulatio Genus


The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower leg.[6] The joint is bathed in synovial fluid which is contained inside the synovial membrane called the joint capsule. The posterolateral corner of the knee is an area that has recently been the subject of renewed scrutiny and research.[7]




articulatio genus



It must be regarded as consisting of three articulations in one: two condyloid joints, one between each condyle of the femur and the corresponding meniscus and condyle of the tibia; and a third between the patella and the femur, partly arthrodial, but not completely so, since the articular surfaces are not mutually adapted to each other, so that the movement is not a simple gliding one.


This view of the construction of the knee-joint receives confirmation from the study of the articulation in some of the lower mammals, where, corresponding to these three subdivisions, three synovial cavities are sometimes found, either entirely distinct or only connected together by small communications.


When standing erect in the attitude of "attention," the weight of the body falls in front of a line carried across the centers of the knee-joints, and therefore tends to produce overextension of the articulations; this, however, is prevented by the tension of the anterior cruciate, oblique popliteal, and collateral ligaments.


The knee joint is a synovial joint that connects three bones; the femur, tibia and patella. It is a complex hinge joint composed of two articulations; the tibiofemoral joint and patellofemoral joint. The tibiofemoral joint is an articulation between the tibia and the femur, while the patellofemoral joint is an articulation between the patella and the femur.


The tibiofemoral joint is an articulation between the lateral and medial condyles of the distal end of the femur and the tibial plateaus, both of which are covered by a thick layer of hyaline cartilage.


The patellofemoral joint is a plane joint formed by the articulation of the patellar surface of femur (also known as the trochlear groove of femur) and the posterior surface of patella. The patellar surface of femur is a groove on the anterior side of the distal femur, which extends posteriorly into the intercondylar fossa.


The case records, clinical, radiographic, ultrasonographic and arthrocentesis findings from 25 cattle with septic or traumatic arthritis were reviewed. The total of 30 joints involved were: articulatio cubiti (elbow joint)-1, articulatio carpi (carpal joint)-10; articulatio genus (stifle joint)-4, articulatio tarsocruralis (tarsocrural joint)-8; articulatio metacarpo-/metatarsophalangea (metacarpo-/metatarsophalangeal joint -7. Ultrasonographic investigation was performed using 7.5 MHz linear and 5 MHz sector transducers. In eight cattle, a concurrent infection of periarticular tendon sheaths or hygroma was diagnosed. The distension of the joint cavities could be imaged in all cases. Assessing echogenicity, acoustic enhancement, ultrasonographic character of the exudate (liquid or clotted) and findings revealed by aspiration, arthrotomy or at necropsy, the synovial effusion was classified as: serous, fibrinous or fibrino-purulent. Diagnostic ultrasound provided a comprehensive preoperative diagnosis in septic and traumatic arthritis by imaging the accurate localization of soft-tissue swelling and the extent and consistency of joint effusion.


Der Innenmeniskus ist mit dem hinteren Anteil des medialen Kollateralbands verwachsen, woraus eine geringere Beweglichkeit bei Beugung und Streckung des Kniegelenks sowie eine erhöhte Verletzungsanfälligkeit resultiert. Der Außenmeniskus ist nicht mit dem extrakapsulär verlaufenden Kollateralband verwachsen. Vorne sind beide Menisken durch das Ligamentum transversum genus verbunden.


Ventral des Kniegelenks - also auf der Streckseite - liegt die Regio genus anterior. Die korrespondierende Körperregion auf der Beugeseite heißt Regio genus posterior. Hier befindet sich die Fossa poplitea (Kniekehle). In ihr verlaufen wichtige Blutgefäße und Nerven, unter anderem die Arteria poplitea und der Nervus tibialis. Außerdem findet man hier einige Lymphknoten (Nodi lymphatici poplitei).


Anaesthetic agent techniques are helpful, as a result of no or little amounts of systemically given medicine have to be compelled to be used and as a consequence few aspect effects, like obtunding mental operate and nausea/ projection have to be compelled to be encountered. Arthroscopic procedures of the knee and articulatio talocruralis joints are well matched for anaesthesia techniques. The surgical amount generally offers issues, once the anaesthetic agent wears off. One in every of the main stays for treatment of surgical pain is opioids. Throughout the previous few years, a replacement idea has developed, a peripheral approach with regionally administered opioids. Many studies have reportable pain relief when arthroscopic surgery of the knee by administering morphia regionally postoperatively [1]. Metallic element Pethidine (meperidine) is a stimulating substance with each anaesthetic agent and opioid effects. There are reports describing pethidine because the sole anaesthetic for caesarean delivery and prostate surgery. In Associate in Nursing earlier study, we tend to found pethidine to be associate in nursing equal different to prilocaine once administered intra- articularly into the articulatio genus for arthroscopic surgery throughout the surgical amount, pethidine was even higher than prilocaine, with less pain and fewer consumption of analgesics throughout the primary twenty four hours. At the day surgery unit of our hospital, most arthroscopic procedures of the articulatio talocruralis are performed underneath anaesthesia, in distinction to the routines of the many alternative units [2]. Diagnostic surgery or arthroscopic soft tissue surgical process when long-standing pain caused by distortion are the most procedures. The aim of this study was to check pethidine and prilocaine intraoperatively and postoperatively once administered intra-articularly into the articulatio plana, of interest was to ascertain if pethidine was able to manufacture important surgical physiological state as compared with prilocaine.


Patients scheduled for surgery of the articulatio talocruralis underneath anaesthesia were bestowed a form concerning surgical and surgical anxiety and expectations, and surgical experiences when acceptance to participate. The study was approved by the native committee, and before taking part, every subject was informed of the character and purpose of the investigation.


Most patients were happy with this type of anaesthetic procedure, though six patients wouldn't select anaesthesia once more for articulatio plana surgery, as a result of pain and discomfort practised throughout the procedure. A careful choice of patients and thorough info are necessary to realize sensible medical aid and happy patients. Within the current study, any variations between the 2 teams regarding intraoperative pain and discomfort, that is in accordance with associate in nursing earlier study victimization pethidine or prilocaine for physiological condition in articulatio genus surgery. It appears cheap to assume that the main action of pethidine within the joint is anaesthetic agent, as a result of pethidine has the flexibility to dam nerve physical phenomenon. Caesarean delivery has been performed underneath spinal anaesthesia victimization pethidine because the sole anaesthetic. A central action of pethidine can't be excluded, considering absorption of pethidine into the circulation from the joint. However, no patient within the current study exhibited any subjective aspect effects like light headedness and nausea preoperatively and postoperatively, indicating low levels of pethidine within the circulation and CSF [4]. A big distinction was noted between pain at rest and pain at movement postoperatively, together with all patients, that isn't shocking and in agreement with knowledge from others, accenting the requirement for separate assessments. The numerous distinction over time each for pain at rest and movement in each teams is attention-grabbing, showing a pain intensity peak at eight hours (40 to 60/100) when surgery. Surgical pain management should be adjusted consequently, justifying potent analgesics, like ketobemidone or methadon, 1 for the first surgical amount. There was no distinction in pain intensity between the two teams throughout the primary eight hours of the surgical amount and at movement throughout the entire observation amount, though pain at rest for zero to three days showed a big distinction. Pethidine decreases pain yet as prilocaine postoperatively.


There is a bent for higher pain reduction with pethidine. Many mechanisms are often attributed to those results. Many investigators have reportable sensible surgical physiological state victimization intra- articularly administered morphia. Morphia made important physiological state when a pair of to four hours, and therefore the impact lasted up to forty eight hours. Pethidine had a faster onset, may be explained by the surgical administration. The short period of impact by pethidine might partially result to irrigation performed throughout the procedure reducing the native concentration of pethidine and therefore the lipophilicity decreasing concentration in joint tissue as compared with morphia. The simplest way to approach this downside would be to administer another dose of pethidine instantly when finishing surgery and hopefully have a quick onset as a result of the anaesthetic agent properties and a lasting surgical pain free amount because of opioid effects. However, the anatomy of the articulatio plana with a superficial connective tissue capsule would solely end in discharge of the drug once administered postoperatively. 041b061a72
