Joint mobilization is a manual therapy intervention, a type of straight-lined, passive movement of a skeletal joint that addresses arthrokinematic joint motion (joint gliding) rather than osteokinematic joint motion. It is usually aimed at a 'target' synovial joint with the aim of achieving a therapeutic effect. These techniques are used by a ...
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 ...
The sole reliance on the hip joint to control the entire prosthetic limb makes fine-tuning foot placement difficult. Lowering the knee joint height was found to effectively increase the hip joint's lever arm, thereby increasing precision control of the hip joint to improve gait symmetry and increase running velocity by 26% on average. [66]
The patella's posterior surface is covered with a layer of smooth cartilage, which the base of the femur normally glides smoothly against when the knee is bent. However, in some individuals the kneecap tends to rub against one side of the knee joint, irritating the cartilage and causing knee pain.
In biomechanics and strength training, ROM refers to the angular distance and direction a joint can move between the flexed position and the extended position. [1] The act of attempting to increase this distance through therapeutic exercises (range of motion therapy— stretching from flexion to extension for physiological gain) is also ...
The PCL is located within the knee joint where it stabilizes the articulating bones, particularly the femur and the tibia, during movement.It originates from the lateral edge of the medial femoral condyle and the roof of the intercondyle notch [2] then stretches, at a posterior and lateral angle, toward the posterior of the tibia just below its articular surface.
It is composed of strong, fibrous material and assists in controlling excessive motion by limiting mobility of the joint. The anterior cruciate ligament is one of the four main ligaments of the knee, providing 85% of the restraining force to anterior tibial displacement at 30 and 90° of knee flexion. [2]
People with joint hypermobility may develop other conditions caused by their unstable joints. [6] [7] These conditions include: Subluxations or dislocations, especially in the shoulder; Joint instability causing frequent sprains, tendinitis, or bursitis when doing activities that would not affect others. However, a 2018 study reports that while ...
