A Prospective Randomised Study on Non-Surgical Management of Knee Osteoarthritis in the Elderly: Role of Exercise, Bracing, and Lifestyle Modification
Background: Knee osteoarthritis (OA) is a chronic, degenerative joint disorder and a leading cause of disability among the elderly. It is characterized by progressive cartilage loss, pain, stiffness, and reduced mobility. With the growing aging population and limited surgical accessibility, non-surgical management remains the cornerstone of OA care. Interventions such as exercise therapy, bracing, and lifestyle modification have shown promising results in improving function, alleviating pain, and delaying disease progression. Aim: To evaluate and compare the effectiveness of exercise therapy, bracing, and lifestyle modification in the non-surgical management of knee osteoarthritis among elderly patients. Methods: This prospective randomized clinical study was conducted in the Outpatient Department, Department of Orthopedics, Government Medical College, Sindhudurg, Maharashtra, from August 2024 to July 2025, including 120 elderly patients diagnosed with primary knee OA. Patients were randomly assigned into three groups: Group A: Exercise therapy (quadriceps strengthening, stretching, and aerobic activity)
- Group B: Bracing (unloader brace or neoprene sleeve)
- Group C: Lifestyle modification (weight management, posture correction, and ergonomic advice)
Each intervention lasted 12 weeks, with assessments at baseline, 6 weeks, 3 months, and 6 months. Outcomes were measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Visual Analogue Scale (VAS) for pain. Statistical analysis was done using SPSS v26.0, with a significance level of p< 0.05. Results: Out of 120 participants, 114 completed follow-up. The mean WOMAC score decreased significantly in all groups—Exercise: 63.1 → 37.2, Bracing: 61.7 → 41.5, and Lifestyle: 62.5 → 48.6. Correspondingly, VAS scores improved from 7.0 → 3.9, 7.2 → 4.5, and 7.1 → 5.6, respectively. The percentage reduction in WOMAC and VAS was highest in the exercise group (41% and 44%), followed by bracing (33% and 37%), and lifestyle modification (22% and 21%) (p< 0.001). At 6 months, 92% of exercise group participants maintained symptom improvement versus 85% in bracing and 76% in lifestyle groups. No major adverse effects were observed. Conclusion: All three non-surgical modalities—exercise therapy, bracing, and lifestyle modification—proved beneficial in managing pain and improving function in elderly knee OA patients. Among them, structured exercise therapy demonstrated the most significant and sustained improvement, making it the most effective conservative approach. Bracing served as an effective adjunct, while lifestyle modification reinforced long-term outcomes. The results support a multimodal, patient-centred, non-surgical approach to optimize quality of life and delay surgical intervention in elderly patients with knee osteoarthritis.
