Osteosynthesis of a patellar fracture with repair of the knee extensor mechanism: Case report
Patella fractures correspond to 1 % of all fractures. In recent decades, the role of the patella in increasing the lever arm of the quadriceps has been well defined. Surgical treatment is indicated for open fractures, those that compromise the function of the extensor mechanism, those with a joint g...

description | Patella fractures correspond to 1 % of all fractures. In recent decades, the role of the patella in increasing the lever arm of the quadriceps has been well defined. Surgical treatment is indicated for open fractures, those that compromise the function of the extensor mechanism, those with a joint gap >5 mm and/or joint incongruity >3 mm, a group that corresponds to around 30 % of the total. Anatomical reduction and stabilization with various types of modified tension bands is the most frequently used procedure. Biomechanical studies have shown that stabilization through the use of a tension band replacing the Kirchner wires with cannulated screws presents adequate resistance to fracture displacement and provides greater stability than the classic configuration, maintaining the theoretical principle of converting the forces of anterior tension of the patella generated by the quadriceps in compression at the level of the articular surface. A case of a patient who required reduction and osteosynthesis of an exposed patella fracture, associated with an extensor mechanism lesion, is presented. Clinical and radiographic characteristics of the patient and the resolution of the case are described. |
