Objective:To investigate the effect of cable pin internalfixation for treatment of patellar fracture.Methods:12 cases with patellar fracture were treated by cable pin internalfixation.Results:The post-operative function in 12 cases was evaluated according to Lu Yu-pu score

follow-up averaged 10 months

and the results were :excellent in 9 cases(75%);good in 2 cases(16.7%);fair in 1 cases(8.3%);poor in 0 case.The excellent rate was 91.7%.Conclusion:Patellar fracture treated with cable pin has the advantages of simple manipulation

firm fixation

faster and guaranteed fracture heeling and good function of knee.The method meets the demands of biomechanics and the clinical result of this group is quite satisfactory.It is advisable to use it in clinical practice.
