Knee Cap (Patello-Femoral) Problems

What is Patella?

The patella (knee cap) is a tiny bone that may be touched in front of the knee. It runs in a groove in front of the thigh bone’s lower end. It increases the mechanical efficiency of the knee, which is especially beneficial when getting up from a sitting position and moving up and down stairs.

The patella is affected by two basic issues. The first is anterior knee pain caused by injury to the patella’s undersurface (chondromalacia), and the second is patella instability. In the first, the patient complains of pain, while in the second, the patella tends to jump out of its groove.

Chondromalacia patella:

Chondromalacia is a condition in which the articular cartilage covering the rear of the knee cap softens. Injury, overuse, patella malalignment, and muscle weakness are the most common causes of this disease in young people, particularly women. The damage might range from a slightly irregular cartilage surface to one that has been worn down to the bare bone. Injury-related chondromalacia develops when a blow to the knee cap pulls a small piece of cartilage away from the bone (osteochondral fracture).

How does one know that he has chondromalacia?

The most common symptom is a dull discomfort around or beneath the knee cap that becomes worse when ascending stairs or over slopes. When climbing stairs or other tasks like rising up from a sitting position, a person may experience pain. A touch on the patella can commonly detect crepitus during an examination.

Treatment of Chondromalacia:

Exercises to strengthen the thigh muscles should be done by chondromalacia patients. If this doesn’t help, you could need arthroscopic surgery to smooth out the cartilage’s surface and “wash out” the cartilage fragments that cause the joint to catch when bending and straightening. In more severe situations, surgery to adjust the angle of the knee cap and reduce friction may be required.

Patella Instability:

This is a group of illnesses in which the patella (knee cap) does not fit snugly into the groove in which it travels. In its most common form, the instability manifests as a dislocation of the patella, with the patient being able to identify exactly what happened, i.e., the knee cap popped out. Actual dislocation may not occur in more modest forms, but the patient has a tendency to lose control of the knee. Pain is frequently the only indication of patella instability.

What is the treatment for recurrent dislocation of the patella?

Treatment is determined by the underlying cause. Often, the cause is a simple injury in which the thigh muscles tense and pull the patella, rupturing the ligaments that hold it in place. If the dislocation occurs again, the damaged ligament should be repaired (MPFL reconstruction). In other circumstances, dislocation occurs as a result of a developmental issue with the knee’s creation. This can take the shape of two highly placed patella, a leg malformation that allows the patella to jump out, and so on. The effectiveness of this type of patella dislocation operation is contingent on accurately detecting and addressing the problem.
