Patella fracture

A patella fracture or broken knee cap is usually caused by forceful direct blow.  Most often the fracture is caused by a single crack across the knee cap by a single incident and, more rarely, the knee cap may be broken into several pieces.  

Simple patella fractures are usually dealt with by immobilising the knee joint in a plaster for 6 weeks.  However, more severe patella fractures can require surgery to restore the knee cap to its original position.  

Once the patella has healed the lower limb is usually weak and physiotherapy is required to build up muscle strength and balance.
