Researchers from the Radiological Society of North America (an international society of radiologists, medical physicists, and others) found that a strong quadriceps muscle reduces stress on arthritic knees, potentially eliminating the need for joint replacement. results published In Radiological Society of North America (RSNA).
Knee osteoarthritis is one of the leading causes of disability worldwide. The disease occurs as a result of mechanical destruction of normal joint structures, changes in the capsule and cartilage damage. The function of the knee joint can be improved with an endoprosthesis procedure, which involves removing the knee joint and replacing it with an implant. The endoprosthesis is located where the damaged structure is located and fulfills its function. In this case, movements are not accompanied by pain and discomfort.
However, joint health can be maintained without such surgeries. Conducting a study with the participation of 134 volunteers, scientists found that a developed quadriceps (this muscle covers the entire front of the thigh and part of its lateral surface) and the muscles of the back of the thigh reduce the likelihood of needing it. total endoprosthesis. The muscles on the back of the thigh, known as the hamstrings, are responsible for hip extension and knee flexion, while the quadriceps move the lower leg at the knee joint. They are extremely important for physical activity.
Researchers compared the leg muscle strength scores of 67 patients who underwent total knee replacement surgery with those of 67 control participants who did not undergo surgery. A high quadriceps/hamstring volume ratio was associated with a lower likelihood of needing total arthroplasty.
The researchers noted that their study could help develop training programs aimed at improving leg strength in patients with arthritis. Such measures will help improve the motor functions and well-being of people with this disease.
