Patellar fractures constitute approximately 1 percent of skcletal injuries in the literature and 3.4 percent in the author's institution. The goals of treatment me restoration of the extensor mechanism and perfect restoration of the articulating surface. In contrast to moat other intraarticular fractures, the selection of treatment must take into consideration tensile stress of the bone, as well as compressive stress. The basic schema for treatment of patellar fracture is as follows: 1. To determine therapy. patellar fractures must be classified in 3 models;The mechanism of injury, amount of displacement. and configuration of fracture. 2. Nonoperative treatment is indicated if the extensor retinaculum is intact and if dispiacement of fragment is minimal. 3. The success of operative treatment depends on 0a exact reduction of fracture, secure fixation, and the amount of articular cartilage damage. 4. Recent biomechanical studies on the efficiency of various forms of fixation for patellar fractures showed that fixation with modified tension band wiring with or without circumferential wiring was superior to tension band wiring or circumferential wiring. 5. Partial patellectomy should be selected in preference to total patellectomy if at all possible because partial patellectomy offers better function.
