Figure 1From: Articular cartilage mineralization in osteoarthritis of the hip Cartilage mineralization and clinical relationships. Contact radiography (DCR) of tangential cut cartilage and slab specimens revealed mineralization in all articular cartilage specimens. The mean area of mineralization was 1.25% (± 0.14 SE, range 0.1-4.6%) for the tangential cut cartilage and 3.69% (± 0.31 SE, range 0.3-12.1) for the slab specimens. Scatter plots show a highly significant inverse correlation between HHS score and mean cartilage calcification for both the tangential cut articular cartilage and the slab specimens (A and B) (p < 0.01, p = 0.01). There was no correlation between patient age and the mean area of cartilage mineralization (C and D) (p = 0.342, p = 0.070).Back to article page
