  1. The P value indicates the level of significance for changes between year one follow up (FU) versus baseline (BL) data using a paired t-test.
  2. ccMF = central subregion of the weight bearing medial femoral condyle; cMF = weight bearing medial femoral condyle; cMFTC = central medial femorotibial compartment; cMT = central subregion of the medial tibia; MC% = mean change (in %); MFTC = medial femorotibial compartment; MT = medial tibia; SRM = standardized response mean (mean change/SD of change).
