After middle age, the tendons and ligaments of the knee joint begin to undergo degenerative changes, the synovial fluid secretion in the joint cavity decreases, the bone surface of the joint rubs together for a long time to form bone wear, and the tissues around the joint are prone to fibrous adhesions due to inflammation.
This is why the elderly often feel stiffness in their knee joints. When they move, they will make a “clicking” sound or frictional sound, and when they are cold or overly active, they will experience pain, swelling, and fluid accumulation in the joint cavity, and in severe cases, they will have deformed joints and become disabled. Specifically, the causes of knee pain in the elderly are as follows.
1, chronic synovitis: chronic pain and swelling in the knee joint. Synovial effusion and synovial hypertrophy can be seen on physical examination.
2. Patellar deviation: the knee joint is sore and weak after activity, improves after rest, and is painful when semi-squatting.
3, free body in the knee joint: the patient’s leg is weak or has a feeling of joint jamming, and there is a friction sound under the patella.
4, prepatellar bursitis: there is a history of trauma, causing prepatellar pain, and localized pressure pain on physical examination.
5, osteoarthrosis: joint pain is obvious after sitting or squatting for a long time, when standing up or going up or down stairs, and relieved after rest.
6, pseudogout: more male patients, preferably in the knee joint. X-rays show calcification of meniscus and articular cartilage surface.
7, femoral head necrosis: hip lesions with knee pain symptoms.
Pain in different parts of the knee joint
1, pain in the lateral iliotibial band of the knee.
2, pain around the knee before the knee, also called patellofemoral joint pain.
3, Pain above the knee, which may be quadriceps tendonitis.
4. Pain above the kneecap or on the inside of the upper tibia, which may be bursitis.
Daily care for sore knees.
1, do not walk too long on the road, and rest immediately when your knee feels uncomfortable.
2, do not do heavy exercise, such as running, high jump, long jump.
3, avoid half squat, full squat or kneeling position. Such as squatting horse stance.
4, do not do the knee joint half flexion rotation action, to prevent half plate injury.
5, maintain the ideal weight to reduce the burden on the knee.
6, pay attention to the warmth of the knee, you can wear long pants, knee pads to protect the knee.
7, less heavy lifting, less wearing high heels.
8.Avoid trauma and overwork.
9, the choice of shoes is very important. A pair of shoes that fit can not only make you walk comfortably, but also reduce the impact and pressure on the knee during exercise.
(1) The instep part of the foot can be closely combined with the shoe, the width and length are appropriate, and can correctly maintain the curvature of the arch.
(2) the weight of the shoe to light, the sole should not be too soft, and to a little thickness.
(3) The heel of the shoe can be about 2-3 cm high, the sole is too flat is easy to get tired when walking.
(4) shoes with non-slip pattern on the sole.
