Proprioception, the perception of limb position in space, is derived from afferent signals originating primarily from musculotendinous and joint receptors. Proprioception is critical to the maintenance of joint stability. Studies have demonstrated that proprioception is less accurate in patients with knee osteoarthritis versus elderly control subjects, in healthy older versus younger subjects, and in the setting of other conditions affecting the knee including anterior cruciate ligament deficiency and hypermobility syndrome. Possible pathways between proprioceptive inaccuracy, knee osteoarthritis, and related knee disorders are described.
本体感觉，即对肢体在空间中位置的感知，源于主要来自肌腱和关节感受器的传入信号。本体感觉对于维持关节稳定性至关重要。研究表明，与老年对照受试者相比，膝骨关节炎患者的本体感觉准确性较低；与年轻受试者相比，健康老年受试者的本体感觉准确性较低；在包括前交叉韧带损伤和关节过度活动综合征在内的其他影响膝关节的疾病情况下，本体感觉准确性也较低。本文描述了本体感觉不准确、膝骨关节炎及相关膝关节疾病之间可能的关联途径。
