BMI. serum uric acid levels are recorded, knee joints x ray done for them, and classified into 5 grades (grade 0-grade 4). serum uric acid level classified into 3 classes (low 2.5. normal 2.5-6, high more than 6 mg\dl) establishing the diagnosis of knee degenerative arthritis according to criteria of ACR (American college of rheumatology. The aim of the stud was to find relation between serum uric acid level with knee osteoarthritis and generalized osteoarthritis in Iraqi patients. in this cross-sectional study, 288 patients involved their ages ranged from 45-90 years old mean age 67.5 years; female patients were 216 (75%). Mean age of females 62.5 years. Male patients 72 (25%). Mean age of males 67.5 years. The study shows highest rate of knee OA patients and generalized OA (76.21%, 63.16 respectively) have normal level of uric acid, while only low rate of knee OA patients and generalized OA (21.93%, 31.58 respectively) have high level of uric acid which was NS (P=0.547) This cross sectional study conclude that there was no association between hyperurecemia and knee osteoarthritis nor generalized osteoarthritis
