Effect of SR treatment on subchondral bone mineral-to-collagen ratio. A typical Raman spectrum from the subchondral trabecula. The mineral-to-collagen ratio (υ1-PO43−/proline) was calculated as the raw υ1 phosphate peak intensity (υ1-PO43−, 962 cm−1) per proline peak intensity (856 cm−1). (B) Analysis of the subchondral bone υ1-PO43−/proline. n=8 per group. Mean±SD. cP<0.01 compared with the Sham/NS group. eP<0.05, fP<0.01 vs MMT/NS group.
