Patellofemoral osteolysis is particularly common among athletes and sports enthusiasts, with a higher incidence in women than in men. The main pathological changes are degenerative changes in the cartilage, including swelling, fragmentation and loss of cartilage, and finally the same lesions occur in the corresponding parts of the femoral condyles, developing into osteoarthritis of the patellofemoral joint, which requires good daily preventive and curative measures because its cause is not well understood and clinical treatment is not effective. Patellofemoral osteolysis daily prevention and control measures: 1. Before exercising or participating in sports, warm up by walking or riding a stationary bicycle, and then do stretching exercises. Stretching the muscles in the front (quadriceps) and back (hamstrings) of the thigh can reduce the tension of the tendons and reduce the pressure of the patella acting on the patellofemoral joint surface of the knee during activity. Obesity increases the risk of degenerative diseases of the knee joint (chondromalacia patellae, osteophytes) and will form a vicious circle, the greater the weight, the heavier the pain; conversely, the lighter the weight, the lighter the pain, so weight will be a factor to consider when treating chondromalacia patellae and osteophytes. 3, wear the right shoes, preferably not high heels, when walking or running, the most is to wear shoes that help maintain body balance and lower limb force line. If you have the habit of running and exercising, it is best to wear shock-absorbing shoes when running, and you should also pay attention to changing shoes regularly. Check that your laces are not too long before participating in confrontational remote sports activities. Patellofemoral osteolysis symptoms are often not serious in the early stages, and can be relieved by rest or taking general painkillers. In the late stage of patellofemoral osteoarthritis, the cartilage and subchondral bone in the lesion area have been significantly destroyed, and the cartilage has no regenerative repair ability.
