Patellofemoral probelms

Patella instability (dislocation):

The joint between the kneecap (patella) and the thigh bone (trochlea) can be injured during sports and exercise resulting in dislocation of the patella or damage to the joint surface.
Dislocation of the patella can also occur with minimal trauma in certain individuals. The reason for this can be a small or high patella, abnormal alignment of the tendons of the patella or a shallow groove (trochlea) in the thigh bone. Often it is a combination of these acting together. The initial treatment of patella instability is physiotherapy to target the inside muscles of the leg including the quadriceps (Vastus medialis) gluteal muscles and hamstrings, this is often the only treatment necessary. If physiotherapy does not help the problem then surgery may be indicated. Individuals who suffer from patella dislocations are often predisposed to this by some anatomical variations. Depending on the cause of the dislocations you may require a reconstruction of the ligament on the inside of the patella, an operation to realign the patella tendon or an operation to deepen the groove in the trochlea. Often a combination of these operations is needed.
