What is Knee Osteoarthritis?

Updated: Dec 13, 2023

Knee Osteoarthritis (OA) is the most common form of OA in the body. Among adults 60 years of age or older, the prevalence of symptomatic knee OA is approximately 10% in men and 13% in women in the United States. Knee OA is even more prevalent in today’s society due to the active aging population. Arthritis-related conditions are the second most common reason for medical visits related to chronic conditions, only second to hypertension.

Conservative treatment, such as physical therapy, is one type of intervention that has been proven to aid the individual with knee OA in regaining his or her functional capacity and quality of life. Physical Therapists utilize various interventions to help with pain management and improve knee joint mechanics, lower extremity function, dynamic balance, and fall risk. Therapeutic exercises have been proven to be one of the most effective interventions for knee OA, aimed at improving neuromuscular control, muscle strength, knee ROM, and aerobic fitness.

Commonly in patients with knee OA, pain can be a barrier in participating in therapeutic exercise, but a patient must be educated that increasing the lower extremity strength of the involved limb will decrease internal knee forces, therefore reducing pain and limiting the progression of the disease. Various forms of strengthening programs can be used to rehabilitate knee OA patients. Land-based therapeutic exercises have been proven to provide better carryover in terms of performing daily functional activities, reducing pain, and improving quality of life.
