In recent years, with the increase in tourism activities of middle and elderly people, on the one hand, it has improved the quality of life and interest in life of middle and elderly people, and also as part of fitness activities of middle and elderly people, it helps to improve the cardiovascular function of the whole body and enhance physical fitness; but on the other hand, more and more middle and elderly people have knee injuries during tourism, and after returning home from tourism, they have persistent joint pain and even limited activities, which affects daily life. It affects daily life. According to the characteristics of the onset, we call knee injuries that occur in the middle-aged and elderly during travel, often on the basis of degeneration, degeneration or old injury of the meniscus, with obvious clinical symptoms of further injury, can be combined with ligament injury, patellofemoral arthritis, synovial crease syndrome, osteoarthritis, cartilage injury, etc. collectively referred to as “travel knee The “travel knee”. Patients with “traveler’s knee” often cannot remember a clear history of trauma, but have a history of travel when questioned further, with joint discomfort, pain, and even impaired joint movement occurring during or after travel. After middle age, the human knee joint begins to degenerate, as evidenced by a decrease in the weight-bearing capacity of the articular cartilage, a decrease in the elasticity of the meniscus within the joint, and a decrease in the ability to resist external injury. In addition, the muscles around the knee joint are necessary to maintain joint stability and normal movement. Unfortunately, however, after the age of 40, the muscle strength of the lower limbs begins to decline, even by 20% or more, and decreases year by year as we age. The decline in muscle strength around the knee is reflected in the weakening of the protective effect on the joint, especially the protection of the joint for a significantly shorter period of sustained movement, that is, “muscle fatigue”. At this time, if the joint is in a posture for a long time and suddenly changes position, the muscle reaction is often slow and cannot contract in time to stabilize the joint, resulting in joint damage; then if the walking time is long, such as more than 1 hour of continuous walking, climbing, especially when the road is rough and requires excessive joint protection, the muscle is often prone to fatigue and lose the protection of the joint. The human meniscus is an important protective structure lining the joints and is the most vulnerable tissue in the knee joint. As the human body enters middle age, the meniscus begins to undergo degenerative changes and is highly susceptible to injury from improper exertion, fatigue, overload, etc. The following situations are common in tourism, such as taking transportation for more than an hour and then starting sightseeing activities immediately after arriving at the destination; or following a tour group with a tight schedule of activities for more than a few hours a day, all of which are prone to muscle fatigue and cause knee injuries. At present, travel companies have attached importance to the examination of the whole body of middle-aged and elderly tourists when organizing tours to prevent accidents that may lead to life-threatening injuries, but have not yet popularized the knowledge of joint damage in middle-aged and elderly people. With the booming development of tourism health in China, this knowledge should be popularized as soon as possible to pay attention to the protection of joints in tourism, so that the middle-aged and elderly people can really achieve the purpose of physical and mental pleasure in tourism, and avoid the regret of coming to the pleasure and returning to the disappointment. So, what issues should the middle-aged and elderly travelers pay attention to in order to effectively prevent knee injuries? First of all, the purpose of travel for the middle-aged and elderly should be mainly leisure, exercise, do not pursue the sightseeing and sightseeing. If possible, you should participate in tours that are mainly for the middle-aged and elderly. Tour organizers should arrange tours in accordance with the physiological characteristics of the middle-aged and elderly people. Secondly, the middle and elderly people must do their own adaptability preparations before the tour, including the assessment of the recent physical condition, do not avoid the first recovery from a serious illness or cold, diarrhea, still arrange tours; individuals should also combine the usual fitness, exercise intensity, choose the corresponding intensity of the tour project and travel time; travel should be dressed casually, it is best to use the corresponding sports clothing, shoes and socks, but also equipped with travel straps, knee pads, etc. The following are some of the things that the elderly should pay attention to when traveling. The following are matters that the elderly should pay attention to when traveling: 1, sit in the transport often move the knee joint, do not immediately stand up to take the luggage when you arrive at the destination, should first move the knee a few times, stand up and let the knee joint adapt to 1-2 minutes before taking the luggage. 2. Arrange the diet and rest for the day. The diet should be rich in protein, vitamins, etc. Have enough sleep. During the tour, there should be no general fatigue, dizziness and weakness in the morning every day, otherwise it means that excessive fatigue has occurred and the intensity of the day’s activities should be reduced. 3, travel walking every hour or so should rest for a while, slow activity limbs, waist and back, rubbing thighs, calf muscles. When climbing a mountain should pay attention to sit down regularly to rest. Up the mountain when the joint load is heavy; down the mountain when the thigh muscles are easily fatigued, may cause joint damage, should be noted. Those who had joint diseases in the past should wear knee pads for protection. 4. The health condition of middle-aged and elderly people varies greatly, so they should take appropriate protective measures according to their own physical condition, and it is important to have an accurate assessment of their physical strength and endurance. If you are older and feel physically weak or have discomfort along the way, you should cancel some excursions in time and rest at the site to recover your strength. Finally, if you experience knee discomfort or pain after a tour, you should rest for a few days after returning home, and do local physical therapy and apply ointment. If you do not see any improvement after 1-2 weeks, especially if you have limited joint extension or flexion, you should go to a sports medicine specialist in time to avoid delaying the disease and losing the chance of early cure.
