Background: Osteoarthritis (OA) is a painful social problem, which breaks down the articular cartilage, causes the failure of synovial joints and subchondral bone sclerosis. OA etiology is not completely understood, but joint trauma, infection, obesity, and diseases are the most important risk factors for OA developing. Recent studies suggested inflammatory factors and genetic components can be involved in the pathogenesis of OA. Experimental evidences suggest a linkage between Human Leukocyte Antigen (HLA) genetic diversity and OA. But a few studies have been conducted in this subject.

Objective: To investigate the association between HLA-DRB1*0101 and OA in Iranian patients.

Methods: Thirty patients with knee osteoarthritis and 30 healthy people as the control group were included in the study. Sex, weight, age, Body mass index (BMI) and height of all participants were recorded. HLA-DRB1*0101 was typed by PCR using the sequence-specific primer.

Results: Our results showed 80% of knee osteoarthritis patients were positively HLA-DRB1*0101 (n=24), while only 26.7% of controls were positive (n=8) (P= 0.015).

Conclusion: These findings proposed that there is a significant association between HLADRB1* 0101 and susceptibility to knee osteoarthritis.
