Knee osteoarthritis, one of the most common forms of arthritis affecting over 30 million adults in the U.S., is characterized by the gradual breakdown of cartilage that cushions bones in the knee joint. This deterioration can lead to pain and stiffness, negatively impacting a person’s quality of life, risk of falling, mood, and activity level.
While osteoarthritis often affects older individuals, roughly half of cases occur among people who are still of working age. Risk factors include weak leg muscles, being overweight or obese, being female, having had a prior knee injury, and a family history of the condition. However, lifestyle changes such as eating more plants and less processed food can help reduce inflammation in the body, potentially easing pain from osteoarthritis in all joints. Other treatments may include strengthening thigh muscles, using knee braces, taking anti-inflammatory medications, receiving cortisone injections, or even undergoing knee replacement surgery.
In addition to managing existing cases of osteoarthritis, adopting healthy habits can also help reduce the risk of developing it. Regular physical activity and maintaining a healthy weight are key strategies in lowering this risk. Despite common misconceptions, diet plays an important role as well; consuming a balanced diet rich in whole grains, fruits, vegetables while limiting processed foods can support overall health and potentially protect against osteoarthritis.
