Arthritis Relief Plus (ARP) Cream has been previously shown to relieve joint pain. In this study, MRI was used to evaluate the knees of eight (5 experimental, 3 placebo) osteoarthritic patients before and after a twelve-week course of topical ARP Cream application. T2, T1ρ, and sodium imaging techniques were used to assess the macromolecule content of cartilage. Significant decreases in T1ρ relaxation times and increases sodium signal in the medial femoral condyle regions of the experimental group suggests there may be a benefit to ARP Cream application. However, results should be interpreted with caution due to the small sample size.
