Fractures of patella

ABSTRACT

Patella, the largest sesamoid bone in the human body with its subcutaneous location is more vulnerable to injuries. The stress distribution gets disturbed if the articular surface of the patella becomes incongruous. Most of the patellar fractures occur as a result of a combination of direct or indirect trauma. Transverse, vertical and polar fractures without comminution are either due to stress or due to powerful quadriceps contraction against resistance. Good history, thorough clinical examination and high quality radiographs are mandatory for accurate diagnosis. A number of management approaches are recommended including immobilizing, excision and repair, and internal fixation. Complication of patellar fracture include infection, loss of fixation, knee stiffness and post traumatic osteoarthritis
