HUBUNGAN FREKUENSI INTERVENSI FISIOTERAPI TERHADAP PENINGKATAN FUNGSIONAL PADA KNEE OSTEOARTRITIS LANSIA DI RS BEDAH HASTA HUSADA KEPANJEN

Background: Knee osteoarthritis (KOA) is a degenerative disease that causes pain, functional limitations, and reduced quality of life in the elderly. Physiotherapy plays an important role in KOA management; however, the relationship between intervention frequency and functional improvement remains inconsistent. Purpose: This study aimed to determine the relationship between the frequency of physiotherapy interventions and functional improvement in elderly patients with knee osteoarthritis at Hasta Husada Surgical Hospital Kepanjen. Methods: This study used a quantitative analytical correlational design with a cross-sectional approach conducted from October to November 2025. A total of 30 elderly patients with knee osteoarthritis were selected using purposive sampling. Intervention frequency was assessed through structured interviews, while functional improvement was measured using the WOMAC questionnaire. Data were analyzed using univariate analysis and Spearman’s rho correlation test after the Shapiro–Wilk test indicated non-normal data distribution. Ethical approval was obtained, and informed consent was provided by all participants. Results: Most respondents were aged 55–65 years (70%), female (83%), and classified as obese (50%). Spearman’s rho analysis showed a correlation coefficient of 0.253 with a significance value of 0.177 (p > 0.05), indicating no significant relationship between intervention frequency and functional improvement. Conclusion: There was no significant relationship between physiotherapy intervention frequency and functional improvement in elderly patients with knee osteoarthritis. Functional improvement may be influenced by other factors such as exercise intensity, pain level, adherence to home exercise, and individual clinical conditions.
