Osteoarthritis of the knee is the gradual breakdown of cartilage within the knee joint, which is the cushioning material connected to the bone which helps to absorb impact etc. Without cartilage there is bone on bone contact which creates friction during movement, resulting in pain when in motion.
Due to the nature of the knee joint, the cartilage will continue to degenerate, as bone on bone contact increases over time. As the condition gradually progresses, mobility is further affected.
5 million adults have sought help for knee osteoarthritis in the UK over the last 7 years, with this figure expected to increase to 8.3 million by 2035 which is why early diagnosis and treatment is essential in managing the condition.
