Find out how leg training helps prevent and improve arthrosis

Understand the importance of muscle strengthening to avoid complications

Knee pain during walking, stairs to climb or standing for long periods can be a warning sign for joint wear. In many cases, the lack of strength in the muscles of the thigh accelerates this process, increasing the overload on the knees. To avoid this evolution and maintain mobility over the years, the strengthening of the muscles is an essential strategy.

Strengthening of the quadriceps and its relevance for the knee

Extensor chair, Press legs AND tolence. Certainly, those who attend a bodybuilding gym know that these exercises strengthen the muscles of the legs. But more specifically, they help to make the muscles of the quadriceps stronger – and this can be important to prevent and improve arthrosis.

“Having the muscles of the strongest quadriceps than the rear muscles of the thigh (rear thigh muscles) can even reduce the risk of total knee replacement. The two muscle groups act as opposite forces and their balance allows a wide range of activities while Protects the knee joint “Dr. Marcos Cortelazo, orthopedist on their knees and sports traumatology.

The doctor, who is also a member of the Brazilian Society of Ortopedic and Traumatology (SBOT), relate the fact that “it is necessary to strengthen the two muscle groups”.

Relationship between osteoarthritis and strength of the thigh muscles

Advanced knee osteoarthritis is one of the main causes of pain and disability all over the world. In Brazil, about 12 million Brazilians have arthrosis, according to estimates, being the most common in the knee. It is estimated that more than half of the diagnosticate must finally undergo a total knee replacement surgery. “This recommendation often occurs because of the lack of strength in the muscles of the thigh,” says the doctor.

According to the expert “the extensors, the muscles on the front of the thigh, commonly called quadriceps, are the strongest muscle group of the body and have an essential influence on March, other activities and biomechanics. muscles Around the back of the thigh, known as the knee tendon, they are responsible for the extension of the hip and the flexion of the knee, making them equally essential for physical activity, “he says.

Importance of muscle strengthening for people with arthritis

In 2023, the researchers evaluated the volume of the thigh muscle in 134 participants in Asteoarthritis Initiative, an American study sponsored by the National Institutes of Health. They compared 67 patients undergoing total replacement of a single knee with 67 check participants who have not suffered the replacement of the knee.

“Comparing patients who had a full knee replacement with the control group, a proportion of volume of the highest quadriceps to the thigh tendon was significantly associated with greater possibilities for total knee replacement. The study shows that, in addition to individual muscles , groups, largest extensors muscular groups – in relation to the muscle groups of the knee tendon – are significantly associated with greater possibilities of total knee replacement surgery in two or four years “, says the doctor.

The results have implications for both the interpretation of the image exams and for clinical management. The results suggest that the training programs that strengthen the quadriceps As for the knee tendon it can be useful.

“Although we suppose that the volume of the general muscles is important as a replacement indicator for muscle strength, proportion and, therefore, the balance between extensor and muscles of the knee tendon can be more important and significantly associated with lower replacement possibilities of the knee.

Public benefits in general from the formation of strength

Discoveries can also help recommend strength training for a wider segment of the population. “Although these results are essential for direct therapy in a population with risk of osteoarthritis, even the general public can benefit from these results to prevent adequate strengthening exercises in advance, preventing the arthrosis of the knee”, concludes dr. Marcos Cortelazo.
