[Clinical characteristics of crystal deposits in joints and tendons in patients with gout].

In patients with gout, it is common for ultrasound to find crystals deposited in joints or tendons. The most commonly affected parts include the metatarsophalangeal joint, knee joint, ankle joint, quadriceps tendon, Achilles tendon, patellar tendon, and triceps tendon. There were significant differences among the three groups in age, age of first increase in uric acid, CRP and blood glucose, and the proportion of urinary calculi in patients with crystal deposits was significantly higher than those without crystal deposits.
