The purpose of this study was to examine the physical impairments and functional limitations of individuals with total knee arthroplasty (TKA), as compared with individuals with no diagnosed knee disease (control subjects).
Twenty-nine individuals 1 year following TKA (13 women, 16 men) and 40 age- and gender-matched control subjects (18 women, 22 men) were assessed.
Walking speed, stair-climbing ability, knee torque (in newton-meters), and total work performed during 15 repeated contractions were evaluated.
Walking speeds for men with TKA were 13% and 17% slower at normal and fast speeds, respectively. Their stair-climbing ability was even more compromised (51% slower). Walking speeds for women with TKA were 17% and 18% slower at normal and fast speeds, respectively. Similarly, their stair-climbing time was more compromised (43% slower). Men with TKA were 37% to 39% weaker and performed 36% to 37% less total work of their knee extensors compared with the control subjects. Similarly, women with TKA had knee extensor strength deficits of 28% to 29% and performed 24% less total work.
One year after TKA, marked physical impairments and functional limitations persisted. [Walsh M, Woodhouse LJ, Thomas SG, Finch E. Physical impairments and functional limitations: a comparison of individuals 1 year after total knee arthroplasty with control subjects.
本研究旨在比较全膝关节置换术（TKA）患者与未诊断出膝关节疾病的个体（对照受试者）的身体损伤和功能限制情况。
对29例TKA术后1年的个体（13名女性，16名男性）以及40名年龄和性别匹配的对照受试者（18名女性，22名男性）进行了评估。
评估了步行速度、爬楼梯能力、膝关节扭矩（以牛顿米为单位）以及15次重复收缩过程中完成的总功。
TKA男性患者在正常和快速步行速度下分别比对照慢13%和17%。他们的爬楼梯能力受损更严重（慢51%）。TKA女性患者在正常和快速步行速度下分别比对照慢17%和18%。同样，她们的爬楼梯时间受损更严重（慢43%）。与对照受试者相比，TKA男性患者的膝关节伸肌力量弱37%至39%，完成的总功少36%至37%。同样，TKA女性患者的膝关节伸肌力量 deficit为28%至29%，完成的总功少24%。
TKA术后1年，明显的身体损伤和功能限制仍然存在。[沃尔什M，伍德豪斯LJ，托马斯SG，芬奇E。身体损伤和功能限制：全膝关节置换术后1年个体与对照受试者的比较。
