Study Goals and Findings

Osteoarthritis (OA) is the most common form of arthritis and disability in the Western world. It affects 85% of the population 75 years of age and older and is often considered an inevitable result of aging. Despite the prevalence of osteoarthritis, there are few compelling predictors of disease progression, greatly inhibiting the development of new treatments.

Horizon 1 investigators sought to establish diagnostic tools to effectively predict progression of osteoarthritis, leading to earlier interventions and successful treatment before onset of disability. The research team applied mass spectroscopy to identify new protein markers as diagnostic and predictive measures of knee osteoarthritis development and progression. Fractal signature analysis (FSA), a type of X-ray image analysis, has been determined to be another predictor of knee OA progression. Through clinical application of these detection techniques, doctors may be able to reduce both the prevalence and severity of osteoarthritis.
