A longitudinal MRI analysis was performed on patients with focal cartilage defects of the femur who received either mosaicplasty or microfracture surgical treatment. We examined T1rho and T2 changes at 3-months and 1-year. Additionally, we performed a laminar analysis to compare the superficial and deep cartilage at the repair site and in the surrounding normal tissue.
