Design outcomes

Primary

MeasureTime frame
Knee Joint pain reduction. Timepoint: Baseline assessment (before starting the clinical intervention) and the final therapy session (patient follow-up at months 1, 3, 6, 12, and 24 after the end of treatment). Method of measurement: Assessments of pain extent, pain intensity based on Visual Analogue Scale/Numeric Rating Scale criteria.;Improvement the range of motion in the knee joint motion. Timepoint: Baseline assessment (before starting the clinical intervention) and the final therapy session (patient follow-up at months 1, 3, 6, 12, and 24 after the end of treatment). Method of measurement: Investigation of joint movement restrictions according to the Western Ontario and McMaster Universities Arthritis Index (WOMAC index).;Quality of life improvement. Timepoint: Baseline assessment (before starting the clinical intervention) and the final therapy session (patient follow-up at months 1, 3, 6, 12, and 24 after the end of treatment). Method of measurement: Quality of life assessment based on the SF-36 criteria.

Secondary

MeasureTime frame
Reducing pain score based on Visual Analogue Scale/Numeric Rating Scale citeria, Improvement of joint movement restrictions according to the Western Ontario and McMaster Universities Arthritis Index (WOMAC index), as well as improvement of life quality based on the SF-36 criteria. Timepoint: Baseline assessment (before starting the clinical intervention) and the final therapy session (patient follow-up at months 1, 3, 6, 12, and 24 after the end of treatment). Method of measurement: The study parameters were evaluated using a set of subjective criteria reported by the patient (including assessments of pain extent, pain intensity based on Visual Analogue Scale/Numeric Rating Scale citeria, level of individual functional limitations, and joint movement restrictions according to the Western Ontario and McMaster Universities Arthritis Index (WOMAC index), as well as quality of life based on the SF-36 criteria) and objective criteria (including clinical examination of the knee joint and evaluation with a triple-phase bone scan/SPECT CT).
