In this study, we aimed to explore the relationship between radiological findings and functional status in patients with knee osteoarthritis (OA). In this study, 117 female patients diagnosed with knee osteoarthritis according to the ACR criteria were included. Antero-posterior knee radiographs of the patients were graded according to Kellgren-Lawrence, and functional capacity was evaluated with WOMAC and Lequesne indexes. Quadriceps and hamstring muscle strengths were also concentrically measured using an isokinetic dynamometer, five repetitions at 90°/s and 20 repetitions at 180°/s. In this study, a significant relationship was determined between the age, weight, praying period, and pain period of the patients with the radiological findings. No significant relationship was determined between the functional capacity of knee and muscle strength and the radiological findings. However, left hamstring functioning capacity was found as lower in the group with the radiological findings. The radiological findings in knee OA are not associated with decrease in knee muscle strength and functional capacity. Clinical symptoms such as pain, decrease in range of motion, etc. in knee OA may be responsible for decrease in knee muscle strength and functional capacity.
在本研究中，我们旨在探讨膝关节骨关节炎（OA）患者的影像学表现与功能状态之间的关系。本研究纳入了117例根据美国风湿病学会（ACR）标准诊断为膝关节骨关节炎的女性患者。患者的膝关节前后位X线片根据Kellgren-Lawrence分级，功能能力采用西安大略和麦克马斯特大学骨关节炎指数（WOMAC）和Lequesne指数进行评估。股四头肌和腘绳肌力量也使用等速测力计进行向心测量，在90°/s时进行5次重复，在180°/s时进行20次重复。在本研究中，确定了患者的年龄、体重、患病时间和疼痛时间与影像学表现之间存在显著关系。未确定膝关节功能能力和肌肉力量与影像学表现之间存在显著关系。然而，在有影像学表现的组中发现左侧腘绳肌功能能力较低。膝关节OA的影像学表现与膝关节肌肉力量和功能能力的下降无关。膝关节OA的疼痛、活动范围减小等临床症状可能是膝关节肌肉力量和功能能力下降的原因。
