Conditioning the body to undergo physical stress such as joint arthroplasty has been termed prehabilitation. This case study examined the effect of a 4-week prehabilitation intervention on functional outcomes after total knee arthroplasty (TKA). Two female subjects completed baseline strength and functional assessments before TKA. Subjects were randomized to either a 4-week prehabilitation intervention (ES) aimed at increasing strength and range of motion or a usual care condition (CS). After 4 weeks of training, subjects were reassessed and underwent TKA. Subjects completed a final assessment 12 weeks after TKA. Functional outcomes included 6-minute walk, number of times up from a chair in 30 seconds, proprioception, and self-reported function and pain using the Western Ontario and McMaster Universities Osteoarthritis Index. The data suggest that 4 weeks of prehabilitation had a positive effect on functional task performance and knee proprioception before surgery. After surgery, the ES continued to exhibit higher levels of functioning and less pain compared with the CS. Prehabilitation before TKA may contribute to improved recovery after surgery.
使身体适应诸如关节置换术等身体应激状态被称为术前康复。本案例研究考察了为期4周的术前康复干预对全膝关节置换术（TKA）后功能结局的影响。两名女性受试者在全膝关节置换术前完成了基线力量和功能评估。受试者被随机分为两组，一组接受旨在增强力量和扩大活动范围的为期4周的术前康复干预（实验组，ES），另一组接受常规护理（对照组，CS）。经过4周的训练后，对受试者进行重新评估并实施全膝关节置换术。受试者在全膝关节置换术后12周完成了最终评估。功能结局包括6分钟步行距离、30秒内从椅子上起身的次数、本体感觉，以及使用西安大略和麦克马斯特大学骨关节炎指数进行自我报告的功能和疼痛情况。数据表明，4周的术前康复对手术前的功能任务表现和膝关节本体感觉有积极影响。与对照组相比，术后实验组的功能水平持续较高，疼痛较少。全膝关节置换术前的术前康复可能有助于手术后恢复情况的改善。
