The patella is the flat, round bone that can be felt in the anterior part of the knee. It articulates with the femur and comprises the tendon of the quadriceps muscle of the leg.
When there is an alteration in any of these three structures (tendon, patella, femur), there is a continuous pain in the anterior part of the knee and a rubbing sensation when bending the knee.
The diagnosis is based off of a correct physical examination and imaging testing such as an X-ray or a knee ultrasound.
The treatment must correct the cause of its onset to avoid elongating the symptoms. The pain and inflammation will be managed with analgesics and anti-inflammatory medication. Hot and cold therapy can favour the recovering process.
If the described symptomatology is present, the recommendation is to visit the traumatologist to confirm the diagnosis and start early treatment.
