A 65-year-old uncle Wang in Taichung retired at home. Because he used to work in storage, he often stood continuously for more than 3 hours. It is commonplace to stand for more than 10 hours all day long. In addition, he loves sports and occasionally participates in many trips during holidays. After running, I felt repetitive pain on the inner side of the knee for a long time. I found that it was already degenerative arthritis after I went to the doctor. The doctor suggested to disperse the pressure on the plantar and change the force on the inner side of the knee through customized insole treatment, which greatly reduces the stress on the plantar and knee. If you feel uncomfortable, you will not be afraid of standing for a long time.
According to statistics, there are about 3.5 million people in Taiwan suffering from knee joint pain, with a prevalence rate as high as 15%. Zhou Liwei, director of the Rehabilitation Department of Ajou University Hospital, said that patients like Uncle Wang often squat down and stand up repeatedly. If coupled with the lack of proper muscle training, the muscle strength of the lower limbs will be insufficient, which will lead to degenerative arthritis in the upper body for a long time.
Occupational injuries keep degenerative arthritis younger
Zhou Liwei introduced that degenerative arthritis can be divided into primary and secondary. The former is mostly caused by aging, and the latter is mostly caused by injuries, metabolic diseases, and other reasons that destroy articular cartilage.
With the westernization of diet, work patterns and demands, degenerative arthritis is no longer a patent for the elderly, and there is a trend of getting younger, so such as flight attendants, cabinet sisters, operators, nurses, etc. need to stand for a long time. Because of the uneven force on the inner and outer sides of the knee, the knee cartilage is worn out, the medial knee joint space is narrow, and the soft tissue on the inner side of the knee increases, which in turn leads to medial knee pain.
Avoid knee degeneration, weight loss exercises must be done
Shi Gaoshang, director of the Regenerative Medicine Center of Shinkong Hospital, said that because being overweight is a major factor in joint degeneration, the knee joint needs to bear the weight of the body. The heavier the weight, the greater the burden. The knee joint is damaged and degenerated. The faster the speed, so “weight loss” is a major focus of maintaining the knee.
In addition, Shi Gaoshang pointed out that strengthening the strength of the muscles around the knee joint can reduce a load of cartilage in the joint. “As long as the muscles around the knee are strong enough, they can share the pressure on the knee and maintain the mobility of the joint. The aging of the knee joint also has a very important effect.”
Shi Gaoshang pointed out that the most important muscle to protect the knee joint is the “quadriceps”. The quadriceps is one of the largest and most powerful muscles in the human body. It also provides the stability and strength of the knee. The strength of the quadriceps can effectively reduce the burden on the knee.
Knee stuck, unable to stand for a long time, hurry to the hospital to order insoles to delay degradation
Occupational therapist Shi Yiming explained that in addition to weight loss and exercise, insoles can also be used to help delay the rate of degeneration. He explained that through the diagnosis of rehabilitation physicians and the measurement of plantar pressure and correction of foot shape by the therapist, the best arch-supporting surface can be made into a customized footpad, which can not only assist the plantar fascia and Muscle tension provides heel and arch to absorb the impact of the weight of the foot. Coupled with the lateral wedge-shaped design, it can also reduce the stress on the inside of the joint.
In addition, people who are affected by O-legs, flat feet, plantar fasciitis, scoliosis, pelvic crookedness, etc., can also be customized according to their body shape and plantar stress conditions, which can effectively reduce symptoms.
Zhou Liwei reminded me that knee jams, inability to stand for a long time, squatting, and kneeling are precursors of degenerative arthritis. To prevent premature aging of the knee joints, it is recommended that the public should control their weight, exercise appropriate exercises and train the muscles of the lower limbs, and choose appropriate shoes. And the insole can be used to protect the knee properly.
How do choose suitable Insoles?
Generally speaking, the cause of foot discomfort is due to the shoe shape does not fit the foot shape, and the heel is too high. Wearing inappropriate shoes of different sizes can easily lead to foot deformities, even thumb valgus, corns, and calluses. According to research, if you need to stand for a long time due to work, the best heel height is not completely flat, but about 0.6 cm higher than the toe of the shoe, up to 5 cm. In addition, it is important to choose an insole that provides arch support, which can help reduce foot pain. For this reason, the foot surgeon recommends buying shoes at night, because the feet will be swollen, and buying slightly larger shoes can help the feet adapt to the insoles or orthotics that support the arch.
The key points of choosing Insoles for special feet
For people with normal feet, choosing low-heeled, thin, and soft shoes is usually more comfortable and ideal. However, people with flat feet and high arches usually get tired on their feet and need to choose shoes and insoles carefully. For people with flat feet, flat shoes such as flip-flops are not suitable. Due to congenital or acquired influence, the arch of the foot collapses and the footplate becomes flat, and an insole with arch support function is required. Most people with high arches are born with too high medial arches, which make the body’s center of gravity fall on the outside of the foot. Therefore, the insole needs to have a shock absorption ability to reduce the chance of impact on the foot. When choosing shoes or insoles that support the arch of the foot, it is recommended that these two types of people try them on more or find a professional to order it, because the arch of the arch support is too high or too low.
Change your shoes frequently
Wearing high heels for a long time can cause pain in the forefoot, as well as forward pelvis and lower back pain. If you have to wear high heels due to work unavoidable, please change your high heels to low heels when you are resting. This can prevent excessive use of foot muscles and joints. In addition, even if you don’t usually wear high heels, it is recommended to change your shoes regularly. If you wear the same pair of shoes every day, your feet may be exposed to the same pressure for a long time and cause injury.
