高关节负荷、膝关节肌肉无力和本体感觉敏锐度差是与膝骨关节炎（OA）相关的重要因素。我们之前报道过单侧髋关节骨关节炎和双侧无症状膝关节相对于同侧膝关节更容易在对侧膝关节发生进行性骨关节炎。在本研究中，我们评估了四肢之间肌肉力量和本体感觉的不对称性，并评估了这些因素与关节负荷之间的关系，这些因素可能与该组骨性关节炎的不对称演变有关。对62名有症状性单侧髋关节骨关节炎和无症状膝关节的参与者进行肌肉力量、关节位置感和膝关节动态关节负荷的评估。比较四肢肌肉力量和本体感觉，并评估这些因素与动态关节负荷的相关性。亚组分析也只在那些满足严重髋关节骨关节炎标准的参与者中进行。股四头肌肌力增加15%，在严重亚组中，单侧髋关节OA患者对侧膝关节本体感觉敏锐度比同侧膝关节差25% （P <0.05）。此外，在患肢，本体感觉敏锐度下降与膝关节负荷增加之间存在相关性（Spearman’s rho = 0.377, P = 0.007），本体感觉敏锐度下降与肌力下降之间存在相关性（Spearman’s rho = - 0.328, P = 0.016）。本研究证明单侧髋关节骨关节炎患者四肢之间肌肉力量和本体感觉不对称。这些因素的早期改变提示它们可能在该组对侧“OA易感膝关节”的未来OA发展中发挥作用。此外，观察到的本体感觉、负荷和患肢肌肉力量之间的显著关联表明，这些因素可能是相互关联的。
High joint loading, knee muscle weakness, and poor proprioceptive acuity are important factors that have been linked to knee osteoarthritis (OA). We previously reported that those with unilateral hip OA and bilateral asymptomatic knees are more predisposed to develop progressive OA in the contralateral knee relative to the ipsilateral knee. In the present study, we evaluate asymmetries in muscle strength and proprioception between the limbs and also evaluate relationships between these factors and joint loading that may be associated with the asymmetric evolution of OA in this group. Sixty-two participants with symptomatic unilateral hip OA and asymptomatic knees were evaluated for muscle strength, joint position sense and dynamic joint loads at the knees. Muscle strength and proprioception were compared between limbs and correlations between these factors and dynamic joint loading were evaluated. Subgroup analyses were also performed in only those participants that fulfilled criteria for severe hip OA. Quadriceps muscle strength was 15% greater, and in the severe subgroup, proprioceptive acuity was 25% worse at the contralateral compared to ipsilateral knee of participants with unilateral hip OA (P <0.05). In addition, at the affected limb, there was an association between decreased proprioceptive acuity and higher knee loading (Spearman’s rho = 0.377, P = 0.007) and between decreased proprioceptive acuity and decreased muscle strength (Spearman’s rho = −0.328, P = 0.016). This study demonstrated asymmetries in muscle strength and proprioception between the limbs in a unilateral hip OA population. Early alterations in these factors suggest their possible role in the future development of OA at the contralateral ‘OA-predisposed knee’ in this group. Furthermore, the significant association observed between proprioception, loading, and muscle strength at the affected hip limb suggests that these factors may be interrelated.
