Description

Knee protective device

Technical field

The utility model is related to medical protective equipment technical fields, more particularly, to a kind of knee protective device.

Background technology

Cartilage, especially meniscus are during exercise the most vulnerable parts of human body, and are easy fracture.From meniscus Shape and position from the point of view of, briefly, the function of meniscus is stabilized knee, spreads knee joint load forces, promotes Intra-articular nutrition.Just because of the steady load that meniscus is played the role of, just ensure that knee joint all the year round weight loading exercise without Cause damage.Meniscus is like buffer between condyle of femur and tibial plateau, protects the two articular surface, is absorbed downward The concussion of reception and registration, especially in hyperflexion or when stretching, this effect becomes apparent from.When being jumped off from eminence, knee bears body Sizable power caused by weight force effect, but the cartilage of condyle of femur and tibial plateau is not damaged, is because partly The presence of month plate, is dispersed to entire knee joint by this power while bearing, and is not only limited to condyle of femur and contacts on tibial plateau One limitation point.In addition, meniscus can prevent femur to be displaced, because the wedge-shaped body of meniscus can make up condyle of femur It is unbecoming between tibial plateau, surrounding's dead space of circular condyle of femur and tibial plateau is filled, to increase knee joint Stability, and can prevent capsular ligament and synovial tissue from entering between articular surface.Meniscus is also prevented from condyle of femur in shin bone Towards front slide on platform, the pressure in knee joint is adjusted, the lubricating fluid being furnished on meniscus can play lubrication to each portion in joint Effect is to reduce friction.Meniscus itself has good elasticity, elasticity is still kept when it is compressed to 2.5mm from 5mm, in addition Its arcuate profile can make articular cavity edge preferably support synovial bursae.Meniscus can also support the spinning movement of knee, assist The lateral movement in collateral ligaments control joint and the rotary motion for helping joint.

With advancing age, meniscus generate abrasion, porter, football and basket baller, mine tunnel work and It is also common in Army soldiers, in strong physical work or movement, it is easy to impaired, due to the weight of body, meniscus will produce shifting Symptoms, these symptoms such as position, rupture are difficult to reset, even resetting, are not also avoided that the compressing to damaging part, often make breakage It aggravates, femoral condyles face is also caused to be damaged, existing knee protective device is only provided with corresponding protection to the front of knee Pad, has ignored knee both sides.
