Geriatric Physical Therapy (GCS) Complete Practice Test 2026

Exercise and weight loss are recognized as effective non-pharmacological approaches for managing knee osteoarthritis (OA). Engaging in regular physical activity helps to improve strength, flexibility, and overall function of the knee joint. Specifically, exercises that strengthen the muscles around the knee can provide better support and reduce the load on the joint itself. This can relieve pain and improve mobility for individuals suffering from OA.

Weight loss is equally important, particularly for those who are overweight or obese. By reducing body weight, there is less pressure placed on the knee joints, which can decrease pain and improve function. Studies consistently show that even modest weight loss can lead to significant improvements in symptoms and quality of life for individuals with knee OA.

In contrast, while other non-pharmacological treatments can provide benefits, they may not be as foundational as exercise and weight loss in addressing the root causes and symptoms of knee OA. For example, heat therapy and ultrasound can offer temporary relief of pain but do not contribute to long-term improvements in joint function. Similarly, rest and bracing might reduce pain in the short term but can lead to muscle weakness and joint stiffness if overused. Hydrotherapy and manual therapy can provide adjunctive benefits for symptom relief but should complement rather than replace a consistent exercise
