Abstract

Patellar fractures are frequently associated with extensor weakness, stiffness, and patellofemoral osteoarthritis. Fracture displacement (step off >2–3 mm and gap >1–4 mm) and integrity of extensor mechanism of the knee determine definitive treatment. Currently, tension-band wiring remains the most commonly used technique for the management of patellar fracture. However, symptoms and complications related to this technique have been described widely in classic literature. Cannulated screws tension-band, instead typical stainless steel wires, and early ROM are associated with the best outcomes. The development of new implants may improve future functional results. Total patellectomy should only be considered in extreme cases. Every effort should be made to preserve patellar bone stock.
