Open Access Abstract Previous studies have shown a generalised increase in bone mass in patients with osteoarthritis OA . Using molecular histomorphometry this study examined the in vivo expression of mRNA encoding bone anabolic factors and collagen type I genes COL1A1 COL1A2 in human OA and non-OA bone. Bone samples were obtained from the intertrochanteric IT region of the proximal femur a skeletal site distal to the active site of disease from individuals with hip OA at joint replacement surgery and from autopsy controls. Semi-quantitative reverse transcription-polymerase chain reaction analysis revealed elevated mRNA expression levels of alkaline phosphatase p osteocalcin OCN p osteopontin p COL1A1 p and COL1A2 p
