INTRODUCTION​

• A patella fracture is a break in the kneecap bone

• The patella (kneecap) is a part of the extensor mechanism of the knee, allowing you to straighten your knee

• The classification system for patella fractures is descriptive and depends on the location of the fracture on the bone

• 2:1 Male to Female Ratio

CAUSES 

• Patella fractures usually are traumatic and usually occur due to direct impact onto the kneecap

• Can sometimes occur with eccentric knee straightening with the quadriceps in tension

SIGNS AND SYMPTOMS

• Patella fractures are associated with immediate pain and swelling

• Inability to straighten the knee

TREATMENT​​

• Patella Fracture treatment depends on fracture type and displacement (separation of the fracture pieces)

• Patella fractures without significant separation of the fracture pieces and that don't affect your ability to straighten the knee can often be managed without surgery

• Non-surgical management consists of either cast or knee brace locked in extension with protected weight bearing. This is followed by progressive bending of the knee under physical therapy guidance

• Patella fractures with significant separation of the fracture pieces and that affect your ability to straighten the knee are usually managed without surgery

• Surgery consists of repair of the fracture pieces with screws, sutures, metal wires, or a combination of the above
