The impact of preoperative muscle strength on postoperative walking ability in patients undergoing total knee arthroplasty.
Although knee extensor muscle strength is strongly associated with postoperative walking ability (PWA) in patients undergoing total knee arthroplasty (TKA), few studies have considered the impact of both knee extensor and flexor muscle strength. This study aimed to determine whether operative side knee flexor and extensor muscle strength before surgery affects the PWA of patients who undergo TKA while accounting for potential covariates. This multicenter retrospective cohort study involved four university hospitals, and patients who underwent unilateral primary TKA were included. The outcome measure was the 5-m maximum walking speed test (MWS), which was completed 12 weeks postoperatively. Muscle strength was measured as the maximum isometric muscle strength required for knee flexor and extensor. Three multiple regression models with a progressively larger number of variables were developed to determine the predictors of 5-m MWS at 12 weeks post-TKA surgery. One hundred thirty-one patients who underwent TKA were enrolled in the study (men, 23.7%; mean age, 73.4 ± 6.9 years). Age, sex, operative side knee flexor muscle strength before surgery, Japanese Orthopaedic Association knee score, and preoperative walking ability were significantly associated with PWA in the final model of the multiple regression analysis ( R2 = 0.35). The current findings suggest that the operative side knee flexor muscle strength before surgery is a robust modifiable predictor of improved PWA. We believe that further validation is needed to determine the causal relationship between preoperative muscle strength and PWA.
期刊介绍:
International Journal of Rehabilitation Research is a quarterly, peer-reviewed, interdisciplinary forum for the publication of research into functioning, disability and contextual factors experienced by persons of all ages in both developed and developing societies. The wealth of information offered makes the journal a valuable resource for researchers, practitioners, and administrators in such fields as rehabilitation medicine, outcome measurement nursing, social and vocational rehabilitation/case management, return to work, special education, social policy, social work and social welfare, sociology, psychology, psychiatry assistive technology and environmental factors/disability. Areas of interest include functioning and disablement throughout the life cycle; rehabilitation programmes for persons with physical, sensory, mental and developmental disabilities; measurement of functioning and disability; special education and vocational rehabilitation; equipment access and transportation; information technology; independent living; consumer, legal, economic and sociopolitical aspects of functioning, disability and contextual factors.
