The surgical treatment of osteosarcoma with a tibial rotationplasty seems to offer functional advantages in comparison with an above-knee amputation. It has not been established whether the functional advantages are accompanied by a lower rate of energy expenditure during walking. In children with a tibial rotationplasty (n = 15), an above-knee amputation (n = 6), or a hip disarticulation (n = 5), energy expenditure was measured during treadmill walking at various walking velocities. The subjects with a tibial rotationplasty were able to walk faster, but there were no differences between the groups in energy expenditure per unit time or per unit distance. Correction for confounding variables including age, sex, height, time since operation, level of activity, and support during walking in a multiple linear regression model did not reveal any significant differences in energy expenditure during walking between groups. 1992 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation.
与膝上截肢相比，采用胫骨旋转成形术治疗骨肉瘤似乎具有功能上的优势。目前尚未确定这些功能优势是否伴随着步行时较低的能量消耗率。对接受胫骨旋转成形术的儿童（n = 15）、膝上截肢的儿童（n = 6）或髋关节离断的儿童（n = 5），在不同步行速度下于跑步机上行走时测量其能量消耗。接受胫骨旋转成形术的受试者能够走得更快，但各组之间在单位时间或单位距离的能量消耗方面没有差异。在多元线性回归模型中对包括年龄、性别、身高、术后时间、活动水平和步行时的支撑等混杂变量进行校正后，未发现各组之间在步行时的能量消耗有任何显著差异。版权所有1992年，美国康复医学大会和美国物理医学与康复学会。
