Blood flow restriction for knee osteoarthritis introduction Osteoarthritis (OA) is the most common chronic degenerative bone and joint disease in the middle-aged and elderly worldwide and creates a significant amount of disability. It is characterized by cartilage deterioration, joint space narrowing, and osteophyte formation. The knee is one of the most readily affected joints by OA.
The prevalence of radiographic knee OA and symptomatic radiographic knee OA are estimated among older people in the US to be 37.4% and 12.1%, respectively. As a degenerative knee joint disease, the development of knee OA is strongly associated with a variety of factors, including age, sex, and obesity, as well as joint factors such as muscle weakness and joint morphology. Current OA treatment guidelines emphasise exercise to manage OA, and prevent OA-related disability, due to its efficacy, safety and potential utility as a self-management strategy.
A range of exercise options appear safe and effective, including aerobic exercise (AE) and resistance training (RT). One challenge to long-term adoption of exercise for people with knee OA is that exercise can, especially initially, be painful. Not alone is such pain potentially distressing, but it can reduce compliance among people with knee OA due to concerns that exercise is dangerous.
Even though the evidence across various musculoskeletal pain conditions suggests exercise need not be completely painfree to be of benefit, people with knee OA could benefit from exercising with less pain, especially if it allows them to exercise for longer, or at a greater intensity. Weakness of the quadriceps muscle is regarded as a vital risk factor for the incidence and progression of radiographic knee OA and is highly related to the physical function and knee pain of knee OA patients. Additionally, poor limb muscle mass contributes to the severity of knee pain of knee OA and is closely associated with present knee OA.
Blood flow restriction therapy (BFRT) has gained considerable popularity in the last decade as a clinical treatment for painful musculoskeletal conditions. A recent review found that BFRT is a reasonably safe intervention for musculoskeletal disorders. Recent studies indicate potentially greater pain reductions in the anterior painful knee conditions within a single session and over 8 weeks of training compared to a standard strengthening intervention.
If you are experiencing symptoms that may be related to blood flow restriction for knee osteoarthritis, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
