Dosage of Exercise in Knee Osteoarthritis Patients

Knee osteoarthritis is a degenerative condition of the knee joint characterized by damage to the joint cartilage. This can cause pain, stiffness, swelling, and impaired movement of the knee. Physical exercise can be an important part of managing knee osteoarthritis, and the right dose and period of exercise can provide benefits for patients with this condition.

The amount of exercise in patients with knee osteoarthritis must be adjusted to the individual conditions of each patient, including the severity of osteoarthritis, level of physical fitness, and movement limitations. Physical exercise that is too heavy or excessive can worsen the patient's condition, while exercise that is too light can reduce the benefits obtained. Therefore, the dose of exercise must be carefully managed by a competent medical professional or physiotherapist.

Light aerobic exercise is a good choice for knee osteoarthritis patients. Aerobic exercises such as walking, cycling, or swimming can help increase muscle strength, maintain heart health, increase flexibility, and reduce stress on the knee joints. The intensity of aerobic exercise must be adjusted to the level of physical fitness of the patient; generally, it is recommended to be in the range of 40–60% of the maximum heart rate.

Muscle-strengthening exercises are also important for increasing stability and support for the knee joint. Muscle strengthening exercises involve using weights or resistance to work the muscles around the knee, such as the quadriceps, hamstrings, inner thighs, and outer thighs. Muscle-strengthening exercises can be done using aids, body weight, or additional weights such as dumbbells or resistance bands. The dose of muscle-strengthening exercises must be adjusted to the patient's muscle strength and performed with the correct technique to avoid further injury or damage to the knee joint.

Flexibility exercises are also important in the management of knee osteoarthritis. Flexibility exercises such as stretching the quadriceps, hamstrings, and muscles around the knee can help increase the knee's range of motion and reduce the risk of injury. Flexibility exercises can be done statically, dynamically, or based on yoga or pilates techniques. Patients must maintain proper technique when performing flexibility exercises to avoid muscle or ligament injuries.
