Osteoarthritis (OA) is a functional disease with joint degeneration with subchondral and periosteal lesions. Coxarthrosis (or hip osteoarthritis) is an important cause of disability, especially in the advanced age group.Although hip osteoarthritis is often thought to be a non-inflammatory pathology, recent studies have shown that joint degeneration is correlated with the production of inflammatory factors and cartilage destroying enzymes.

There are very few studies evaluating the correlation of Neutrophil lymphocyte ratio, monocyte lymphocyte ratio and Platelet lymphocyte ratio with inflammatory parameters CRP and ESR levels in hip osteoarthritis and its relation with the staging of hip osteoatritis.

Osteoarthritis (OA) is a disease characterized by joint degeneration with subchondral and periosteal lesions . Coxarthrosis (hip osteoarthritis) is an important cause of disability, especially in the advanced age group. The risk of symptomatic coxarthrosis in persons up to the age of 85 is approximately 25%. There is a possibility of total hip replacement at a rate of approximately 10% due to advanced stage coxarthrosis. Kellgren-Lawrence staging system is used to show disease severity in osteoarthritis staging. According to this, Stage 0: there is no radiological change, Stage 1: there is a slight narrowing in the joint space, Stage 2: osteophytes are formed in the joint space with stenosis in the anteroposterior radiography, Stage 3: multiple osteophytes, significant narrowing of the joint space, sclerosis and Stage 4 It describes a situation accompanied by large osteophytes, severe stenosis in the joint space, prominent sclerosis, and bone deformities.

Although coxarthrosis is often thought to be a non-inflammatory pathology, recent studies have shown that joint degeneration correlates with the production of inflammatory factors and cartilage destroying enzymes. At the cellular level, it has been found that macrophage and perivascular T and B lymphocyte infiltration play a role in early and advanced stage OA.

Neutrophils and lymphocytes are the main determinants of the inflammatory process. The neutrophil to lymphocyte ratio (NLR) is obtained by dividing the absolute neutrophil count by the number of lymphocytes obtained from the peripheral blood count. They are used as an indicator of the inflammatory process in inflammatory conditions such as ankylosing spondylitis, sarcoidosis, and cancers. In addition, platelet lymphocyte ratio (PLR) has also been found to be associated with disease activity and severity in diseases such as rheumatoid arthritis and psoriatic arthritis. Its use in the diagnosis and follow-up of OA has not yet been clearly demonstrated. However, changes in mean platelet volume are also used as an indicator of disease severity in systemic inflammatory diseases.

There are very few studies evaluating the correlation of Neutrophil lymphocyte ratio, monocyte lymphocyte ratio and Platelet lymphocyte ratio with inflammatory parameters CRP and ESR levels in hip osteoarthritis and its relation with the staging of hip osteoatritis. The aim of this study to evaluate of the correlation of the inflammatory parameters with pain and radiological findings in the patients with coxarthrosis.
