To compare the weight bearing of men and women during standing and squatting after knee replacement surgery for osteoarthritis.
Two-group, single-surgeon study with patients selected consecutively through a sample of convenience. Patients evaluated at first outpatient rehabilitation visit and at discharge from outpatient services.
Outpatient orthopedic institute.
Seventeen women (average age, 71 years) and 16 men (69 years) who underwent primary unilateral knee replacement for osteoarthritis.
Percentage of body weight placed over the surgical limb during standing and during 30° and 60° squats.
The men placed a greater percentage of body weight over the surgical limb during the 30° and 60° squats, both at the initial visit and at discharge. Both women and men had similar improvements with all dependent measurements.
The magnitude of change for women and men was similar, yet percentage of body weight placed over the surgical limb in women was less than in men at the initial visit and did not match that in their male counterparts by discharge.
比较膝关节骨关节炎置换术后男女患者在站立位和蹲位时的负重情况。
连续选择样本的两组成员、单医生研究。患者在首次门诊康复就诊时和离开门诊服务时进行评估。
门诊骨科研究所。
17 名女性（平均年龄 71 岁）和 16 名男性（69 岁），因膝关节骨关节炎行初次单侧膝关节置换术。
站立位和 30°、60°时手术肢体承受的体重百分比。
男性在 30°和 60°时手术肢体承受的体重百分比均大于初始就诊和出院时的女性。女性和男性所有依赖测量值均有相似的改善。
女性和男性的变化幅度相似，但女性在初始就诊时手术肢体承受的体重百分比低于男性，且在出院时未达到与男性相当的水平。
