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 ...
Autologous chondrocyte implantation (ACI, ATC code M09AX02 ()) is a biomedical treatment that repairs damages in articular cartilage.ACI provides pain relief while at the same time slowing down the progression or considerably delaying partial or total joint replacement (knee replacement) surgery.
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 [5] then stretches, at a posterior and lateral angle, toward the posterior of the tibia just below its articular surface.
Complaints of locking sensation in the knee joint can be divided into true locking and pseudo locking. True locking happens when the intra-articular structure (e.g. ligaments) [1] is damaged, or a loose body is present inside the joint, or there is a meniscal tear. The knee can be unlocked by rotating the leg and full movement can be restored.
Adopting any other posture while floating requires muscular effort. In the 1980s, NASA developed the Man-System Integration Standards (MSIS), a set of guidelines based on anthropometry and biomechanics, which included a definition of an average typical NBP created from measurements of crew members in the microgravity environment onboard Skylab.

To counteract this moment, an internal knee flexion moment is generated to assist with stabilizing the knee joint as it prepares for weight acceptance. Once the foot is flat the vertical ground reaction force moves posterior to the knee joint as the trunk glides over the stance foot, resulting in an external knee flexion moment.
Sometimes they report weakness or decreased range of motion. The physician examines the knee in full extension, looking for tenderness in the medial knee joint and across the proximal, medial tibial region, and feels for tenderness along the medial tendons of the pes anserine when the knee is flexed at 90 degrees.

The LESS is a valid and reliable tool for the biomechanical assessment of the jump landing technique. [1] [2] The LESS involves the scoring of 22 biomechanical criteria of the lower extremity and trunk, with the outcomes being associated with the risk of anterior cruciate ligament (ACL) and patellofemoral injury.
