Eligibility
Age
50 Years to 75 Years
Inclusion criteria
Inclusion criteria: Participants eligible for the study will be those aged between 50 and 75 years; of both sexes; who report being able to perform the proposed exercises (table 1); who accept the terms of the informed consent form (ICF); who are not engaged in another physical exercise program; who do not present cardiovascular, metabolic, or musculoskeletal conditions unrelated to knee osteoarthritis that may prevent the execution of the evaluation tests and the home exercise program; who present a diagnosis of unilateral knee osteoarthritis according to the Ahlbäck classification modified by Keyes et al. (1992), being grade I reduction of joint space or grade II obliteration of joint space or grade III wear of the tibial plateau 10 mm in the sagittal plane; who are classified as candidates for primary total knee arthroplasty; who have some means of direct contact or through a close relative to facilitate communication; in the case of patients in the experimental group, who have availability for telerehabilitation sessions, access to communication via WhatsApp, and conditions for conducting supervised videoconferences
Exclusion criteria
Exclusion criteria: Patients will be excluded if they present unexpected adverse events that compromise the safety or continuity of the home-based physical exercise program; if they do not attend the scheduled telerehabilitation sessions; if they do not respond to communication attempts via WhatsApp; if they do not achieve the minimum score required on the Mini-Mental State Examination (MMSE) adjusted to their educational level with a score below the cutoff value indicating cognitive impairment which may compromise the proper understanding of the home-based exercise program as well as the use of WhatsApp for conducting and monitoring activities; if they have a cancellation or rescheduling of the surgical procedure
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Assess the feasibility of implementing a training program by analyzing adherence rates throughout the intervention period, measured through diaries completed by participants and calculated as the percentage of the total number of sets performed in relation to the prescribed total | — |
Secondary
| Measure | Time frame |
|---|---|
| Evaluate the effectiveness of the training program based on the results obtained in parameters such as postural control, muscle strength, performance in functional tests, and changes in anthropometric measurements. The tests used for these evaluations include the Mini-Mental State Examination and the Western Ontario and McMaster Universities Osteoarthritis Index. Postural control will be assessed using a smartphone, the Time Up and Go walking test, and the sit-to-stand test. Anthropometric measurements will include the evaluation of total body mass, height, and waist circumference. Muscle strength will be measured through isokinetic dynamometry. Analyze hospital outcomes based on the length of hospital stay, hospital readmission rate, and the number of surgical complications occurring within 30 days after the procedure, calculating the total number of hospitalization days and adverse events related to surgery | — |
