Objective    To explore the curative effects of open reduction and internal fixation with Cable Pin or tension band wire for patellar transverse fractures.     Methods    Totally 28 cases and another 30 cases were enrolled in the Cable Pin group (8 months for average follow-up time) and the tension band wire group respectively (16 months for average follow-up time). The operative time

the average clinical healing time and the average range of the knee flexion between the 2 groups were compared.     Results    Obvious superiority was observed in the Cable Pin group over the tension band wire group concerning the average clinical healing time and the average range of the knee flexion 6 months postoperatively (P0.05).     Conclusion    The way that treating patellar fractures with Cable Pin is characterized by simple manipulation

rigid fixation

rapid healing

high healing rate and excellent function of the knee

and this internal fixation which acquires satisfactory results is in accordance with biomechanics and deserve the clinical expansion.
