How to Reverse the Progression of Osteoarthritis
As our population ages, the number of Australians with osteoarthritis is expected to rise from 2.2 million in 2015 to 3.1 million by 2030.(1) The condition ranks as the most common form of arthritis
. It involves the wearing down of cartilage at the ends of bones. In osteoarthritis, the degeneration of joints progresses over time. For many patients, it progresses to the point of needing surgery. There is no cure, so the goal of treatment is to improve pain and function for as long as possible.
When osteoarthritis starts slowing a person down, healthcare guidelines generally recommend treatments that fit the following criteria:
- Conservative
- Exercise-based
- Non-surgical
- Non-pharmacological
Nevertheless, a high percentage of patients reporting osteoarthritis pain are not offered exercise therapy.(3) This is unfortunate considering that exercise therapy is known to reverse the progression of osteoarthritis.
For instance, J. H. Abbott (Department of Surgical Sciences, Dunedin School of Medicine, University of Otago, New Zealand) recently published an interesting study measuring the cost-effectiveness of adding different types of physiotherapy to real-world usual care.(4) Usual care involved seeing the primary care provider and receiving whatever advice and/or medications were recommended. Researchers divided patients into groups receiving no physiotherapy, manual therapy, exercise therapy supervised by a physiotherapist, or a combination of the two. Abbott and colleagues measured healthcare spending for two years.
After two years, exercise therapy (when added to usual care) cost less than usual care alone. Supervised exercise therapy saved more in healthcare spending than the other three groups. The main reason for this was that patients in the exercise therapy group continued to get better even after their initial seven physiotherapy visits were over. Patients in the usual care group and the other groups tended to show the usual progression of arthritis. This was probably because patients with ample exercise therapy visits learn to continue their therapeutic exercises independently. It appears that supervised exercise therapy is a way for patients to take charge of their osteoarthritis and manage its progression themselves.
