9-year-old Xiaojun (pseudonym) accidentally sprained his knee while moving 3 years ago, and there was no obvious discomfort at that time.
Two years ago, Xiaojun began to have knee pain and swelling, but he still did not pay attention to it, and before February, Xiaojun found that the discomfort symptoms gradually worsened, and there was no obvious relief after resting.
At the time of consultation, the doctor found that the right knee joint tenderness was positive, the lateral space tenderness was negative, the hyperextension or hyperflexion pain was negative, and there was no obvious abnormality in the sensation and movement of the limbs.
After being admitted to the hospital, Xiaojun completed relevant examinations, including: blood routine, urine routine, liver function, kidney function, electrolytes, etc., and there were no obvious abnormalities; The ECG shows sinus rhythm and is generally normal.
The doctor fully communicated with Xiaojun and his family, considering that his symptoms were not relieved for a long time, and there was no obvious organic damage on MRI of the knee joint, indicating that there was a small amount of fluid in the right knee joint and bone edema at the posterior edge of the patella, it was recommended to use physical conservative treatment.
After Xiaojun and his family agreed, the doctor gave acupuncture to promote local blood circulation, infrared anti-inflammatory and analgesic, ultra-short wave to promote muscle tissue cell regeneration, and intermediate frequency pulsed electrical therapy to reduce edema, and after hospitalization for 14 years, Xiaojun's knee pain and swelling symptoms were alleviated, and the physical examination results showed that the right knee joint tenderness was negative, the lateral space tenderness was negative, the hyperextension or hyperflexion pain was negative, the floating patella test was negative, the muscle strength and muscle tone of the limbs were not abnormal, the pain and temperature perception of the limbs were not abnormal, and the knee and Achilles tendon reflexes were not abnormal.
The doctor reminds that sprain is a common problem in clinical practice, ankle sprain, knee sprain is often encountered in daily life, this problem should be ruled out in the early stage, local strict immobilization, early ligament and other structures can be fully recovered, if the early stage is not timely and appropriate treatment, the later stage may cause long-term chronic strain, the quality of life of the patient has an impact, therefore, if the patient has no discomfort symptoms after the injury, he should also go to the hospital for examination, if there is pain, swelling, do not delay, Early detection, early diagnosis, and early treatment.
The knee is the most important joint in our body, the largest and most complex joint in the human body, among which the knee joint is a hinge joint, which is one of the few joints in the body that can only move in one direction.
At the same time, the knee joint is also the weakest joint in the human body and is the most commonly injured part of the body.
Inappropriate exercise in daily life may cause damage to the knee joint, and even leave indelible sequelae, such as long running, climbing, climbing stairs, squats and frog jumping.
People often ridicule themselves for being in their 20s, but they have 50-year-old knees, and joint problems are very common among the younger generation.
According to statistics, about 23% of adults and 29% of adolescents in the general population will suffer from patellar pain every year.
Nowadays, many people think that running hurts their knees, but they don't know that many of their daily bad habits are the main culprits of knee injuries.
These 4 movements really hurt the knee
01 Climb the stairs
Climbing stairs and running have some damage to the knee joint, but climbing stairs hurts the knee even more.
Because running is the stretching and contraction of the quadriceps muscles, driving the joint movement of the muscles of the whole lower limb, the focus of the lower limbs during the exercise is mainly on the tibial articular surface and the meniscus of the knee joint, so the damage to the knee joint of fast running is mainly in the femoral cartilage and meniscus, and the damage to the meniscus is greater for long-term fast running, while the damage to jogging will be relatively low.
Stair climbing is to use the knee joint as the fulcrum, at a slower speed, from flexion of the patellar ligament to the extension of the knee joint, the whole process of the patellar cartilage and patellar surface load is large, a single action to complete the time is long, the wear and tear of the lateral femoral cartilage, patellar surface and patellar cartilage is also greater, and the clinical manifestations of knee injury will be more serious.
In addition, the cartilage surface is the most susceptible to damage, and after a long time, the cartilage will gradually disappear, and the friction between bones will gradually lead to hyperplasia and calcification, and the joint space will become very narrow and uneven, and there will be obvious pain and unfavorable movement when climbing stairs.
Especially for women after the age of 50, women in the menopausal period will cause aggravation of joint degeneration due to the decline in estrogen levels in the body, and bone hyperplasia is more obvious, so special attention should be paid to avoid climbing stairs too much.
02 Sedentary
An international authoritative study has pointed out that the incidence of arthritis in fitness runners is 3.5%; In sedentary people, the incidence of arthritis is as high as 10.2%.
When sitting for a long time, the knee will be in a flexion position for a long time, and the local blood vessels will be bent for a long time, which may affect the blood circulation of the lower limbs, and then affect the blood supply to the knee area, which may lead to knee ischemia and hypoxia, and easily cause joint damage.
Sitting for a long time may lead to degeneration of the cartilage inside the joints, which may cause edema of the surrounding ligaments and joint capsule, causing swelling and pain.
In addition, if you sit for a long time and do not pay attention to your sitting posture, it may increase the burden on the spine and easily cause diseases such as lumbar muscle strain, lumbar myofasciitis, lumbar disc herniation, and cervical spondylosis.
Therefore, it is not recommended to sit for a long time in daily life, so as not to affect the blood circulation of the lower limbs, and then affect the function of the joints.
It is recommended that office workers get up and move their joints properly every 1 hour or so (not more than 2 hours), and at the same time, they should also pay attention to keeping their knees warm and avoid getting cold, so as not to aggravate the symptoms and affect the function of the knees.
03 Squatting for long periods of time
Some people like to squat for a long time due to work reasons, or personal habits, and squatting often is a bad habit, which is easy to cause continuous physical pressure on the knee, resulting in fatigue of the knee joint, and will cause local structural damage or structural changes for a long time.
Prolonged squatting will cause squeezing of the joint space, that is, causing greater pressure on the meniscus of the knee joint space, accelerating the degeneration and aging of the meniscus, or causing local damage.
When squatting for a long time, the articular surfaces of the patella will be tightly together, causing local compression, and the increase of local pressure may cause local circulatory disorders, and if the cartilage is too tight, it may cause pressure and damage to the articular cartilage.
In addition, because the tension is too large, it will affect the local microcirculation, if the nutritional status of the cartilage itself is not good, there is no large number of blood vessels, there is a lack of synovial fluid in the joint cavity, and the pressure is too great, it will affect the microcirculation, and it is easy to form patellar arthritis for a long time.
In addition, the quadriceps muscles of the thigh and the ligaments under the patella, when squatting for a long time, are also in a long-term stretching state, which will cause local tension, and in the case of increased tension, the microcirculation will be affected, resulting in local defects, and long-term continuous damage to the local muscle fibers or ligament fibers, which may accelerate its degeneration, cause direct bleeding or injury, and even tear, degeneration, etc., which will lead to local pain, restriction or joint instability.
04 I don't usually have the habit of exercising, and I suddenly go wild
People who don't usually exercise much and sit for a long time every day can easily cause meniscus damage if they suddenly go abruptly, and may even cause damage to the soft tissues around the joints.
Therefore, you should exercise according to your ability and not do strenuous exercise, otherwise it will be counterproductive.
How to take care of your knees on a daily basis?
1. Change the way of exercise, do not do exercises with heavy knee strain, and avoid repeated knee flexion and extension wear.
2. Warm up properly before knee flexion and extension to avoid sports injuries.
3. Wear protective gear before doing strenuous activities.
4. Don't walk too many steps a day, 10,000 steps is enough.
5. Control your weight to avoid overweight and the burden on your knee joint.
6. Do more functional exercises that help your knees, and the most common exercises are the quadriceps muscles.
7. Usually you can supplement calcium appropriately, spend more time in the sun, drink more milk, soy milk, bone broth, etc.
8. Keep your knees warm every day, add clothes when the weather changes, and apply warm compresses if necessary.
9. If you have severe knee pain and need to go to the hospital for examination, you will be treated with hot compresses, physiotherapy, intra-articular injections and other treatments according to the doctor's advice, and in severe cases, surgery may be required.
