Due to aging, sick or unexpected, lesion or degeneration can occur for the bone of human body or joint, and human body lower limbs bone or lower limb The lesion of Bones and joints or degeneration may seriously affect its weight-bearing function, and then influence the standing of human body, walk and jump of running. In this regard, generalling use drug therapy, traditional physical therapy and rehabilitation, operative treatment is used when serious to restore leg bone or joint Function.In rehabilitation, orthoses is usually used.

Orthoses (orthosis) is also known as brace (brace), is abnormal to prevent, correct for human limb or other positions Shape, treatment bone, joint, nerve, muscle illness and the device outside for compensating its function, it is by limitation or assists body kinematics, Or change the body line of force the effects of, with mitigate four limbs, backbone, Musculoskeletal dysfunction.It is different according to applicable position, Upper limb orthoses, spinal orthosis and lower limb orthosis can be divided into.Wherein, upper limb orthoses are mainly used for what compensation lost Muscular strength, limbs, holding or the fixed limb of helping paralysis and function digit provide tractive force to prevent contracture and/or prevention or rectify Positive deformity；Spinal orthosis is mainly used for the flesh for mitigating local pain, protecting diseased region from further damaging, supporting paralysis Meat and/or prevention, correction deformity；Lower limb orthosis is mainly used for fixed lesion joint, prevention or correction deformity, compensatory loses Muscle function improves gait, avoids limbs load-bearing, union and early function is promoted to restore.

Knee joint is one of important weight-bearing joint of human body lower limbs, as shown in Figure 1, it is connected to thigh femur 1 and shank Between shin bone 2 comprising articular cartilage 4, medial meniscus 5 and lateral meniscus 6.Kneecap 3 is also shown in Fig. 1 and shin bone is thick Grand 7.

When lesion occurs for knee cartilage, such as Osteoarthritis (OA), will lead to articular cartilage gradually be denaturalized, is downright bad, It wears, starts mutual direct friction between subsequent bone (i.e. femur and shin bone), thus cause gonalgia, and influence patient Daily life.In addition, knee joint aging, injury of knee joint, heredity, obesity or the overexercise also volume caused by knee joint Outer weight bearing.For these knee joint problems, provides to provide in rehabilitation and avoid or mitigate the limbs of knee joint part and hold Weight, that is, having the lower limb orthosis for exempting from lotus (or exempting to carry) function is the recovery for being conducive to mitigate the pain of sufferer and help patient 's.
