Fractures of the patella

Patellar fractures usually occur from distraction and three-point bending of the patella as well as from direct blows. Surgical treatment is necessary for fractures that are displaced more than 2 mm and may include open reduction and internal fixation, partial patellectomy, or rarely, total patellectomy. We have presented a new technique for the stabilization of a simple transverse fracture that has provided superior results in laboratory tests. Postoperative complications can be minimized by good attention to wound care, accurate fracture reduction, secure fracture fixation and an early range of motion. Despite the surgeon's best efforts, however, post-traumatic osteoarthrosis can develop and may require additional treatment.
