Many strength trainees, bodybuilders, and exercisers are told that there should be a certain ratio between the strength of their hamstring and quadriceps muscles. Called the H/Q ratio and reported to be anywhere from .50 to .75 with a normative value of .60, the strength ratio of this important agonist/antagonist pairing is considered essential to the stability of the knee joint and to prevent ACL and other injuries. It is also sometimes thought to be predictive of those at risk for hamstring strain.

Plica syndrome is a post-traumatic or post-inflammatory thickening, chronic inflammation (synovitis), and/or fibrosis of the synovial plicae of the knee. This means that the plica (PLI-kah) have been irritated by overuse or injury to the knee. Most commonly affecting the medial plica, the symptoms mimic those of other other knee problems, such as a torn meniscus, causing patella pain, snapping, clicking, and tenderness of the joint. There may be a sense of instability in the knee and a knee-locking sensation. Bibliography item klippel not found.,Bibliography item wheeles not found.

The knee joint is one of the major weight bearing joints, it has to cope with walking, running, bending, jumping and lifting objects. It also works in conjunction with the hip & ankle joints, assisting in static erect posture (standing). So not only does the knee joint need to offer stability & weight support, but it must also offer considerable mobility. It is no surprise then that it is one of the most commonly injured joints in the human body.

Bursitis involves inflammation or irritation of the bursa of a joint. The word bursitis comes from the word bursa and "itis" which means inflammation.
A bursa is a small, synovial fluid containing sac surrounded by a membrane. These sacs act as cushions for the joints. Located in areas that are subject to friction, as when a muscle or tendon is pulling around a corner or over a bone, their purpose is to cushion and lubricate the tissues.Bibliography item acr not found.,Bibliography item jhwhite not found.

The human knee is a very complicated joint. Two major bones come together at the knee — the femur (thigh bone) and the tibia — (shin bone). There is a third bone located at the knee — the patella (knee cap), but it does not participate in the joint between the femur and the tibia. The lower end of the femur has two side-by-side convex curved surfaces, while the upper end of the tibia has two side-by-side concave curved surfaces. The convex surfaces on the femur are obviously designed to fit into the concave surfaces on the tibia. But there are several things located in between.

Although sometimes associated with the elderly, iliotibial band syndrome (ITBS or ITBFS, for iliotibial band friction syndrome) commonly affects the thighs and knees of runners, cyclists, hikers, and weight lifters. Squats, in particular, may cause this often acutely painful injury, providing a good case for proper form and adequate warm-ups and cool-downs.
