Static or dynamic postural control cannot be fully restored in patients with knee osteoarthritis, even after total knee arthroplasty (TKA), which may contribute to an increased risk of falls in the elderly.
To evaluate balance and the fall risk before and after TKA in patients with bilateral knee osteoarthritis. Secondary outcomes were patient-reported and performance-based activity limitations.
A total of 45 patients were separated into two groups as unilateral TKA (UTKA, n= 24) and bilateral TKA (BTKA, n= 21) groups. All the patients received standard postoperative physical therapy for 3 months. Balance and fall risk (Biodex Balance System SD), patient-reported and performance-based functionality (WOMAC, 30-second chair-stand test, 9-step stair climbing test and 40-meter fast-paced walk test) and Short Form-12 (SF-12) were evaluated at preoperatively, and at 3 months postoperatively.
There was no difference between the groups in postoperative fall risk and balance (p> 0.05). The BTKA group obtained better results in the sit-to-stand test and SF-12 physical dimension (p< 0.05).
UTKA and BTKA interventions and the standard postoperative rehabilitation were seen to improve balance and quality of life, and reduce the fall risk, patient-reported and performance-based activity limitations. However, despite improvements in balance, the risk of falling persists.
即使在全膝关节置换术（TKA）后，膝关节骨关节炎患者的静态或动态姿势控制也无法完全恢复，这可能导致老年人跌倒风险增加。
评估双侧膝关节骨关节炎患者 TKA 前后的平衡和跌倒风险。次要结果是患者报告的和基于表现的活动受限。
共有 45 名患者分为单侧 TKA（UTKA，n=24）和双侧 TKA（BTKA，n=21）两组。所有患者均接受标准术后物理治疗 3 个月。在术前和术后 3 个月评估平衡和跌倒风险（Biodex 平衡系统 SD）、患者报告的和基于表现的功能（WOMAC、30 秒坐立试验、9 步爬楼梯试验和 40 米快步走试验）和简短形式 12（SF-12）。
两组术后跌倒风险和平衡无差异（p>0.05）。BTKA 组在坐立测试和 SF-12 生理维度方面获得了更好的结果（p<0.05）。
UTKA 和 BTKA 干预以及标准术后康复均能改善平衡和生活质量，降低跌倒风险、患者报告的和基于表现的活动受限。然而，尽管平衡有所改善，但跌倒风险仍然存在。
