简要总结
Static or dynamic postural control cannot be fully restored in patients with Total Knee Arthroplasty (TKA). Moreover, deficits in balance and postural control may still be present in both extremity after TKA. However, the contralateral knee OA grade, asymmetrical gait pattern, and postural sways still remain a risk factor for balance deficits and falls. Based on this rationale, the aim of this study is to evaluate the balance and fall risk before and after TKA in patients who suffered from bilateral knee osteoarthritis and to clarify the balance and fall risk difference between unilateral and bilateral TKA patients.
详细描述
Falls are one of the leading causes of increased morbidity and mortality in the elderly population and are substantial contributor to increase healthcare cost burden. Pain, strength deficits, knee joint deformities, balance and proprioceptive impairments associated with severe knee OA, contribute to an increased risk of falling among elderly, and more than 50% of this population experience a fall each year. Static or dynamic postural control cannot be fully restored in patients with Total Knee Arthroplasty (TKA). Moreover, deficits in balance and postural control may still be present in both extremity after TKA. Increased weight-bearing on the operative side after TKA and reduced weight-bearing weight in the contralateral osteoarthritic knee can reduce pain and improve balance-related functions. However, the contralateral knee OA grade, asymmetrical gait pattern, and postural sways still remain a risk factor for balance deficits and falls. Based on this rationale, the aim of this study is to evaluate the balance and fall risk before and after TKA in patients who suffered from bilateral knee osteoarthritis and to clarify the balance and fall risk difference between unilateral and bilateral TKA patients.

结局指标
主要结局
Fall risk evaluation
时间窗: 3 months
Fall risk was evaluated using the Biodex Balance System SD (Biodex Medical Systems Inc., Shirley, NY, USA). The Fall Risk test was conducted to identify potential fall candidates. Test results are compared with age-related normative data.
Balance evaluation
时间窗: 3 months
Balance (Postural Stability and Sensory Integration) was evaluated using the Biodex Balance System SD (Biodex Medical Systems Inc., Shirley, NY, USA). Postural Stability Test was applied to determine a patient's ability to maintain the centre of balance. Sensory Integration Test aims to evaluate the individual's ability to both integrate various senses to maintain balance and to compensate when one of these senses is missing. This test included four conditions: Eyes Open-Firm Surface, Eyes Closed-Firm Surface, Eyes Open-Foam Surface, and Eyes Closed-Foam Surface. Each assessment lasted 30 seconds, with 10 seconds of rest in between assessments.
