Knee Osteoarthritis Market Size, Epidemiology, In-Market Drugs Sales, Pipeline Therapies, and Regional Outlook 2025-2035

 Market Overview:

The knee osteoarthritis market reached a value of USD 5.0 Billion across the top 7 markets (US, EU4, UK, and Japan) in 2024. Looking forward, IMARC Group expects the top 7 major markets to reach USD 9.8 Billion by 2035, exhibiting a growth rate (CAGR) of 6.29% during 2025-2035.

The knee osteoarthritis market has been comprehensively analyzed in IMARC's new report titled "Knee Osteoarthritis Market Size, Epidemiology, In-Market Drugs Sales, Pipeline Therapies, and Regional Outlook 2025-2035". Knee osteoarthritis, also referred to as degenerative joint disease, is a condition characterized by the slow deterioration of connective tissues in the knee joint. As the illness progresses, the joint may become inflamed, and bony growths called bone spurs may develop in the affected area. These changes can result in pain, swelling, and difficulty performing daily functions, such as climbing stairs, walking, or bending the knee. The symptoms of the ailment can vary from person to person but commonly include stiffness, grating or popping sensations, reduced range of motion, muscle weakness, instability, etc. The diagnosis of this disorder typically involves a combination of characteristic findings, medical history, and physical examination. The healthcare provider may also perform X-rays to visualize the knee and assess the extent of joint damage. In some cases, numerous other imaging tests, such as computed tomography (CT) scans or magnetic resonance imaging (MRI), may be recommended to obtain more detailed information about the joint structures. Furthermore, an arthrocentesis is conducted to confirm the diagnosis in individuals suffering from the disease.

The increasing cases of structural abnormalities in the knee joint, such as malalignment or instability that can lead to an uneven distribution of forces across the joint surfaces, causing cartilage damage, are primarily driving the knee osteoarthritis market. In addition to this, the expanding geriatric population, who are prone to degenerative changes due to reduced tissue repair capacity, is also creating a positive outlook for the market. Moreover, the widespread adoption of physical therapy, owing to its various advantages, like strengthening the muscles around the knee joint, improving flexibility, and offering pain relief to patients, is further bolstering the market growth. Apart from this, the inflating application of assistive devices, including canes, crutches, braces, etc., that help to reduce stress on the joint and provide support during movement is acting as another significant growth-inducing factor. Additionally, the emerging popularity of hyaluronic acid injections, since they improve the viscoelastic properties of the synovial fluid, thereby decreasing friction between the bones, is expected to drive the knee osteoarthritis market in the coming years.
