“Prehabilitation” with Thera-Band® helps total knee replacement patients recover better

Knee osteoarthritis (OA) is common in older adults, affecting about 4.3 million in the United States. Knee OA sometimes leads to joint replacement surgery in advanced stages of the disease – nearly a half-million total knee replacements are performed annually in the US. Researchers at the University of Louisville wanted to evaluate the efficacy of a pre-operative exercise program (“prehabilitation”) for patients undergoing total knee arthroplasty (TKA) surgery. 54 older adults with knee OA were randomized into a control group (usual care) or an exercise group completing exercise 3 times per week (1 supervised session, and 2 at home). Patients used Thera-Band® Resistance Bands supplied by Thera-Band Academy.

The study, published in Archives of Physical Medicine and Rehabilitation, found that prehab participants significantly increased their leg strength and mobility after surgery, while the control group did not. At 3 months after surgery, the prehab group improved performance on all 4 functional tasks, in contrast to the control group who improved in only 2 out of the 4. Lead investigator, Robert Topp PhD RN, noted, “This Thera-Band exercise program definitely supports the theory of prehabilitation in total knee patients.” Dr. Topp published a similar summary article in the ICAA publication, Functional U. A pre-operative strengthening program with Thera-Band Resistance Bands can help improve function after total knee surgery compared to no pre-op training.

Exercise as good as surgery for knee arthritis

Knee osteoarthritis affects millions around the world with pain and disability. There is no known cure for arthritis, and the course of treatment is based on symptom management through medication, surgery and physical therapy. Some arthritis sufferers believe that exercise may cause more harm than good, and typically opt for arthroscopic surgery to ‘clean-out’ the knee. In addition to the cost of surgery, there are obvious risks. Despite the high number of arthroscopic surgeries for knee arthritis (also known as “debridement”), little evidence supported its efficacy.

Researchers from the University of Western Ontario in Canada performed a randomized controlled trial (the highest level of evidence) on 190 patients with moderate to severe knee osteoarthritis. Their goal was to determine if physical and medical therapy was as effective as arthroscopic surgery. The exercise program lasted for 12 weeks, including one hour per week supervised by a therapist, and daily exercise twice a day. After the 12 weeks, the patients continued their home programs unsupervised.

The researchers found that physical therapy, including Thera-Band exercises was as effective as arthroscopic surgery for treating knee osteoarthritis. Both groups had similar outcomes for pain and function after a 2 year follow-up. The results, published in the New England Journal of Medicine, suggest a structured physical therapy program including Thera-Band elastic resistance can be as effective as arthroscopic surgery for knee osteoarthritis.
