Osteoarthritis (OA) chondrocytes are efficient cells in the uptake of glucose. Differences between human articular normal and OA chondrocytes in the uptake of 2-deoxy-(3H)glucose for 1 hour. The detailed procedure is described in Materials and methods. Values are the mean ± SD; n = 12. *P ≤ 0.05 versus normal chondrocytes.
