Degenerative arthritis of the knee is an inflammation of the joints due to degeneration and destruction of the normal joint tissue structure. The causes of the disease are mainly due to bone deterioration, strain and trauma caused by ageing. 1. Degenerative bone lesions: with age, bone quality deteriorates, leading to degenerative arthritis of the knee joint and osteophytes around the knee joint. The cartilage inside degenerates and breaks, fractures and falls off. 2. Strain: Strain is mostly seen in manual laborers, especially in the lower limbs, where the knee joints are subjected to repeated force and friction for a long time, thus leading to premature degeneration of the knee joints and degenerative arthritis. 3. Trauma: Knee joint stability damage and internal cartilage meniscus damage caused by trauma can also lead to premature degenerative arthritis of the knee joint. Once the degenerative arthritis of the knee joint is found, it is necessary to avoid excessive stress on the knee joint, avoid trauma, avoid cold, so as not to aggravate the degenerative knee arthritis, it is recommended to reduce the amount of activity and avoid excessive exercise. If the symptoms continue to be unable to relieve the need to go to a regular hospital, under the guidance of a doctor.
