The Value of Physical Therapy in Osteoarthritis of the Knee

Osteoarthritis of the knee is the most common type of osteoarthritis, or OA, in the United States. According to the American Physical Therapy Association (APTA), nearly 12.4 million Americans ages 65 or older suffer from symptoms of knee OA, including morning stiffness, pain during or after activity, discomfort after sitting, knee popping or grinding, swelling, and joint tenderness.

Physical therapy is a proven, effective treatment for knee OA. The goal of treatment is to reduce pain, get you moving again, and help you enjoy life’s little pleasures — whether that’s a walk in the park or dancing at a family gathering.

The APTA’s 2023 report highlighted the cost-effectiveness of treating knee osteoarthritis with physical therapy. They used quality-adjusted life years (QALYs) to measure both how long someone lives and their quality of life, making it easier to compare treatments like reducing pain or improving mobility. On average, physical therapy for knee osteoarthritis provides a net benefit of nearly $14,000 per episode of care, including all the hidden costs of your time, pain, missed life events, and the dollars paid for services. Compared to steroid injections, patients who received physical therapy had a 0.07 higher QALY, with only a slight increase in medical costs.

Physical therapy offers patients valuable benefits, including knowledge to help reduce the risk of opioid addiction and cost savings by avoiding invasive steroid injections and surgeries. Additionally, it provides long-term advantages such as improved mobility, balance, strength, and flexibility. These enhancements contribute to better overall health and a lower risk of developing conditions that may require additional healthcare services in the future.

Your physical therapist can refer you to an orthopedic surgeon to discuss your options for dealing with knee OA. If you choose surgery after consulting with healthcare professionals, physical therapy plays a crucial role in both preparation and recovery, as noted by the APTA. Pre-surgery physical therapy (“prehab”) helps improve strength and flexibility, setting you up for a smoother recovery. After surgery, your physical therapist will create a personalized program based on your condition and goals to help restore function and mobility.

If you’re dealing with knee OA, give physical therapy a try. It’s an investment in getting back to the things you love without pain.
