  1. Values presented as mean ± standard deviation. BV/TV, percent bone volume; LT, lateral tibial; MT, medial tibial; OARSI, histological scoring system to grade severity of osteoarthritis; SMI, structure model index; Tb.N, trabecular number; Tb.Sp, trabecular separation; Tb.Th, trabecular thickness. *P <0.001 considered significant comparing MT osteoarthritis versus LT osteoarthritis. P values were determined by two-tailed unpaired Student’s t test.
