Old people often suffer from knee pain due to degenerative arthritis, which makes them inconvenient to move. The common knee pain in young people is usually caused by chondromalacia patellae. Patella softening is mainly due to poor structure, excessive use of knee joint, improper use or external impact, which leads to inflammation and softening of patella articular surface.

2. patella softening can strengthen quadriceps function exercise.

The decline of quadriceps femoris muscle strength is closely related to patella softening, so strengthening quadriceps femoris muscle strength and restoring the stability of knee joint is the core of treating patella softening. Today, I recommend two rehabilitation exercises: lie on your back and lie flat on the bed, straighten your legs with the greatest strength, then lift your legs and raise your heels from the height of the bed 15 cm. Pay attention to straighten the knee joint. After a period of practice, my strength has improved, so I can change my sitting posture. Is to sit on the bed and cross your legs.

3. patella softening can do straight leg lifts.

Lie on your back and lie flat on the bed, first straighten your legs with the greatest strength, and then lift your legs to a height of about 15 cm from the bed. Pay attention to the extension of knee joint to fully mobilize the muscle fibers of quadriceps femoris. Can be tested separately. Straighten and bend slightly. The strength varies greatly, and it can also be seen that the degree of muscle contraction is much worse. After a period of practice, my strength has been improved and I can practice sitting posture. Sit on the bed, sit up straight, and then lift your legs. Because the hip joint bends after sitting up, the iliopsoas muscle relaxes, does not participate in contraction, and does not help the quadriceps, so it is more tired, and the anterior thigh muscle exercises better.

4. patella softening can do resting function exercise.

Resting function exercise is mainly to exercise the strength of quadriceps femoris, enhance the strength of quadriceps femoris, prevent muscle atrophy and avoid the further development of patella softening. Static functional exercise of quadriceps femoris can maintain the stability of knee joint.

5. Chondromalacia patellae can eat more dairy products.

Among ordinary foods, dairy products have the highest calcium content, such as milk, yogurt and ice cream. They not only contain a lot of calcium, but also are rich in phosphorus, another important mineral needed by human body. The proportion of calcium and phosphorus in these dairy products is relatively moderate, which can fully absorb calcium and phosphorus and other substances. Milk also contains protein, lactose and other substances. If you drink 2 cups of milk (about 480 ml) every day, it is enough to meet the calcium needs of adults.
