Methods We conducted a cross-sectional controlled study including US examinations of the knees and first metatarsal-phalangeal joints first MTPJs as well as of the tendons and enthesis of the lower limbs. Differences were estimated by c2 or unpaired t-tests as appropriate. Associations were calculated using the Spearman s correlation coefficient rank test. Results Fifty asymptomatic individuals with hyperuricemia and 52 normouricemic subjects were included. Hyperechoic enhancement of the superficial margin of the hyaline cartilage double contour sign was found in 25 of the first MTPJs from hyperuricemic individuals in contrast to none in the control group P . Similar results were found on the femoral cartilage 17 versus 0 P . Patellar enthesopathy 12 versus P and tophi 6 versus 0 P as well as Achilles enthesopathy 15 versus P were more frequent in hyperuricemic than in normouricemic individuals. Intra-articular tophi were found in eight hyperuricemic individuals but in none of the normouricemic subjects P . Conclusions These data demonstrate that morphostructural changes suggestive of gouty arthritis induced by chronic hyperuricemia frequently occur in both intra- and .
