Knee osteoarthritis: causes, symptoms and treatment

common disease that is associated with the degeneration of the cartilage of a joint. Thus, it tends to affect more the female sex and people over fifty years of age.

As a general rule, this structure is located between the bones that form a joint to avoid friction between them. However, when the cartilage wears out (may eventually disappear completely) its usual functions are affected.

We can also point out that this pathology tends to affect certain joints more frequently. We include osteoarthritis of knees, hands, spine and hip.

This substance is found in the joints, protects it and provides nutrients to the cartilages of it. The diagnosis can also be made by obtaining images of the area through radiographs, ultrasounds and even magnetic resonance imaging (

On the other hand, the ultimate goal of treatment is to alleviate the symptoms that the patient presents and to delay as far as possible the progress of the pathology. Among the most common guidelines we can highlight:

  • Use of analgesic drugs, that is, to calm the pain or discomfort of the joint.
  • Anti-inflammatory medications to reduce swelling of the knees and keep it under control.
  • In the most advanced and serious cases, a surgical intervention can be carried out to reduce the intense pain caused by dislocations. In this case, one of the bones moves away from the joint and dislocates. After surgery, the joint can be replaced or replaced by a prosthesis.
