There are two round knobs at the end of the femur called femoral. The NHS links below give further information regarding arthritis, what it is, types of arthritis & treatment. The knee is a hinge joint made up of two bones, the thighbone (femur) and the shinbone (tibia). The symptoms of knee arthritis include pain (especially on walking and going up and down stairs), stiffness, swelling and sometimes clicking or grating. The temporomandibular joint (TMJ) is a hinge type synovial joint that connects the mandible to the rest of the skull.More specifically, it is an articulation between the mandibular fossa and articular tubercle of the temporal bone, and the condylar process of the mandible. These include previous trauma to the knee (breaks, fractures or ligament tears), previous surgery (such as where the whole meniscus has been removed), other diseases that affect the joints (such as rheumatoid arthritis or gout) and being overweight. When the cartilage is worn away it leaves the hard bare bone surface that may lead to pain and sometimes deformity (such as the bow-leg or knock-knee appearance).Ĭertain risk factors exist for knee arthritis. Knee arthritis occurs where the cartilage (the smooth lining inside of the knee joint) becomes worn away. The knee is one of the more commonly affected joints in the body. Knee arthritis is commonly referred to as ‘wear and tear’ inside the knee joint. Loss of this cartilage occurs in knee arthritis. This cartilage is very smooth and has very low friction, allowing the bones to slide easily over each other to bend and straighten the knee. If symptoms persist, keyhole surgery (arthroscopy) may help.Ĭovering the bones inside the knee joint is articular cartilage. This can then sometimes lead to symptoms of pain, swelling, locking or jamming and the feeling like your knee may give way under you, especially during twisting activities. It is not uncommon for these to become torn. These act like shock absorbers to help with the smooth movements of the knee. Inside the joint there are also two menisci. The knee is made up of three compartments: the medial (on the inside), the lateral (on the outside), and the patellofemoral (at the front). The compartments are all joined together but there are occasions when problems such as arthritis can exist in only one of the compartments of the knee. The articular cavity of three compartments of knee. The ability to straighten the knee is one of the things that is first lost in early arthritis. The joint capsule connected to the femur, patella and tibia was observed to be progressed with periosteum. The knee also has the ability to lock itself straight to help you stand up for long periods of time. At the front of the knee is the patellar tendon that connects the tibia to the quadriceps muscle via the patella bone (knee cap), and this arrangement works to straighten the knee. These include the two cruciate ligaments (ACL and PCL) as well as the two collateral ligaments (MCL and LCL). A number of ligaments stabilize the knee.
