Treatment of osteoarthritis of the knee: evidence-based guideline, 2nd edition
Jevsevar, D.S. (2013) J. Am. Acad. Orthop. Surg. 21(9): 571-6. doi: 10.5435/JAAOS-21-09-571.
For patients with symptomatic OA, the updated guidelines recommended self-management programs, strengthening, and low-impact aerobic exercise as treatments. For patients with symptomatic OA and a body mass index above 25, weight loss was also a recommended treatment.
The guidelines were unable to recommend valgus bracing for patients with symptomatic knee OA due to inadequate evidence supporting its efficacy. However, recommendations state that practitioners should not avoid prescribing valgus braces solely based on the poor research quality.
Relevance to Levitation
– Budarick, A.R. et al. (2020) J. Prosthet. Orthot. Under Peer Review..
Of further therapeutic importance, Levitation has been shown to reduce joint loads by an amount equivalent to 45 lb of weight loss 2– Budarick, A.R. et al. (2020). J. Biomech. Eng. 142(1). For many overweight or obese knee OA patients, a reduction of 45 lb is in line with the amount of weight loss associated with clinically meaningful improvements 3– Messier, S.P. et al. (2018) Arthritis Care Res. (Hobokin) 70(11): 1569–1575. As such, Levitation may provide patients with outcomes similar to weight loss or help them achieve additional weight loss or lead a more active lifestyle through improvements to their levels of knee pain, function, and physical activity levels 4– Budarick, A.R. et al.
