This research is a pre-experimental research utilizing the Pretest-Posttest Design research methodology. The research population consisted of knee injury patients at the Health and Sports Centre (HSC) Therapy Clinic, Yogyakarta State University. The sampling technique employed was purposive sampling using the Slovin formula (20% critical value), resulting in a sample of 25 individuals. The data collected included: (1) Measurement of knee joint pain using the Numeric Rating Scale. (2) The knee joint Range of Motion (ROM) was assessed using an ordinal ROM scale ranging from 0 to 3. The data analysis method employed quantitative descriptive analysis and hypothesis testing through the Wilcoxon Signed Rank Test with a significance level of 5%.

The outcomes revealed that: (1) Massage therapy can significantly decrease the knee joint pain scale (α = 0.00) with an effectiveness of 38%. (2) Massage therapy can enhance the Range of Motion (ROM) scale in knee joint injuries (α = 0.003) with an effectiveness of 15%.
