What is Wrong with My Knee?
Dec. 09, 2020
There is a saying that life is movement. The saying itself is true, but it is not precise. For the vital organs that sustain life, such as the heart, lungs, and brain, exercise improves their function, accelerates metabolism, and has definite benefits for the above-mentioned internal organs. The benefits of moderate exercise for bone and cartilage are also numerous, but it is important to choose the right type and intensity of exercise for you based on your age and the amount of exercise you do on a regular basis. Excessive exercise is at the expense of the motor system, especially the ligaments and cartilage, which serve the internal organs such as the heart, lungs, and brain. There are several conditions that are particularly likely to trigger knee pain.
(1) You have knee pain.
(2) Suddenly increase the amount of exercise you do when you normally do not exercise much. For example, one who usually does not exercise, but suddenly decided to run three to five kilometers today.
(3) People who have just started to lose weight. (3) People who have just started to lose weight. People who are very heavy and their joints are heavily burdened, and then suddenly start exercising without gradual progress, exceeding the load on their knees.
(4) Women over 40 years old and men over 50 years old who do not have long-term exercise habits, go for high-intensity outdoor sports such as hiking, mountain climbing, and travel.
This kind of pain is caused by the sudden increase in the load on the knee joint, which leads to cartilage wear and tear microscopic damage to the trabecular bone, and ligament strain that cannot be repaired in a short period of time. If you go for an MRI, you may be told that there is bone marrow edema in the bones around the knee joint and a small amount of fluid in the joint.
Osteoarthritis is common in older adults. In women, the onset of osteoarthritis begins earlier, in some cases as early as 40 years of age.
It is a normal aging process of the knee joint, and genetics, natural ligament tightness, muscle strength, normal joint development, and body weight determine the early onset and rate of progression of arthritis.
Several characteristics of arthritis.
Common in middle-aged and elderly people
1.Starting pain. For example, it is painful and difficult to get up when sitting for a while, but it gets better after taking two steps.
2.Prominent joint skeletal hyperplasia.
3. Joint deformity.
4. There is often pressure pain in the joint gap and inside the joint.
5.Advanced arthritis hurts when walking on the floor and seriously affects the treatment of life.
Reconstruction with rotating-hinge total knee prostheses can provide a substantial improvement in function and a reduction in pain in extreme circumstances, such as gross instability. We believe this salvage procedure should be reserved for severe ligamentous deficiencies in elderly and sedentary patients or whenever revision surgery techniques fail.
