全膝关节置换术（TKA）后，肌肉和活动能力不足可能持续数年。本研究的目的是（1）确定12周的抗阻运动康复治疗是否会导致TKA术后1 - 4年个体的肌肉大小、力量和活动性增加;（2）比较传统抗阻运动康复计划与侧重于离心抗阻运动的康复计划的肌肉和活动性结局。17例单侧或双侧TKA患者（共24例膝关节）（13例女性，4例男性;平均年龄68岁;年龄范围55-80岁）被纳入这项匹配和随机重复测量康复初步试验。12周离心运动后股四头肌体积和膝关节伸展强度增加。在四项流动性测试中也注意到了改进。在两项流动性测试中，传统组也有类似的改善。在TKA术后1 - 4年的老年人中，12周的抗阻运动可以增加肌肉大小和力量，改善活动水平。当运动模式侧重于离心阻力时，肌肉生长反应更大，在重要的移动任务中也有改善。证据等级：II级，治疗性研究。有关证据等级的完整描述，请参见作者指南。
Muscle and mobility deficits can persist for years after a total knee arthroplasty (TKA). The purposes of this study were (1) to determine if 12 weeks of rehabilitation with resistance exercise induces increases in muscle size, strength, and mobility in individuals 1 to 4 years after a TKA; and (2) to compare the muscle and mobility outcomes of a traditional resistance exercise rehabilitation program with a rehabilitation program focused on eccentric resistance exercise. Seventeen individuals (13 women, four men; mean age, 68 years; age range, 55-80 years) with either a unilateral or bilateral TKA (total of 24 knees) were included in this matched and randomized repeated-measures rehabilitation pilot trial. Increases in quadriceps muscle volume and knee extension strength followed 12 weeks of eccentric exercise. Improvements were also noted in four mobility tests. Similar improvements were noted in the traditional group in two mobility tests. An increase in muscle size and strength and an improvement in levels of mobility can occur after 12 weeks of resistance exercise in older individuals 1 to 4 years after TKA. When the exercise mode focuses on eccentric resistance, the muscle growth response is greater as is the improvement in important mobility tasks.Level of Evidence: Level II, therapeutic study.
