The articular capsule of the knee joint is the wide and lax joint capsule of the knee. It is thin in front and at the side, and contains the patella, ligaments, menisci, and bursae of the knee. [1] The capsule consists of an inner synovial membrane, and an outer fibrous membrane separated by fatty deposits anteriorly and posteriorly. [2]
A tendon is a tough, flexible band of fibrous connective tissue that connects muscles to bones. [12] The extra-cellular connective tissue between muscle fibers binds to tendons at the distal and proximal ends, and the tendon binds to the periosteum of individual bones at the muscle's origin and insertion. As muscles contract, tendons transmit ...
Pes anserinus tendinitis/bursitis syndrome, or pes anserine bursitis, is a cause of chronic knee pain and weakness. [3] [4] It occurs when the medial portion of the knee is inflamed. If the bursa underlying the tendons of the sartorius, gracilis, and semitendinosus gets irritated from overuse or injury, a person can develop this ailment. This ...
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 ...
Knee diagram. Structures on the medial side of the knee include the tibia, femur, vastus medialis obliquus muscle, semitendinosus tendon, gracilis tendon, sartorius tendon, adductor magnus tendon, medial head of the gastrocnemius muscle, semimembranosus tendon, medial meniscus, medial patellofemoral ligament (MPFL), sMCL, dMCL, and POL. It has ...
The tibia (/ ˈ t ɪ b i ə /; pl.: tibiae / ˈ t ɪ b i i / or tibias), also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two bones in the leg below the knee in vertebrates (the other being the fibula, behind and to the outside of the tibia); it connects the knee with the ankle.
To test the reflex, the muscle should be in a neutral position. The muscle being tested needs to be flexed for the clinician to locate the tendon. After the muscle is relaxed, the clinician strikes the tendon. The response should be contraction of the muscle. If this is the knee jerk reflex, the clinician should observe a kick.
A straight-knee calf raise is often done using the leg press machine. The sledge is kept nearly locked out and the exerciser is meant to keep the hip and knee joints immobile. This is not a bodyweight exercise, the only body part actually being lifted is the small weight of the foot. The resistance comes from the sledge.
