The objective of this study was to evaluate the prevalence of sarcopenia in patients on the total knee arthroplasty waiting list in the public health system.
Methods:
A cross-sectional observational study was conducted. Five tools were used to assess sarcopenia: sarcopenia assessment questionnaire, calf circumference, handgrip strength, appendicular skeletal muscle mass loss, and gait speed.
Results:
The prevalence of sarcopenia in the five tools of patients awaiting TKA was: gait speed 79.2%, handgrip strength 24.8%, sarcopenia assessment questionnaire18.8%, calf circumference, and appendicular skeletal muscle mass loss indicating less than 5%.
Conclusion:
The prevalence of sarcopenia was 87.1% among patients on the total knee arthroplasty waiting list. The most affected individuals were older, white, overweight, or grade I obese.
