Abstract

PURPOSE: To evaluate that the radiological and clinical results of transverse patellar fractures treated with cannulated screws and modified tension band wiring by two mini-incision technique.
MATERIALS AND METHODS
We reviewed 20 cases displaced transverse patellar fractures treated with cannulated screws and modified tension band wiring by two mini-incision technique. The radiological assessment was based on the time to union, maintenance of reduction. Mean duration of follow up was 27 months with mean age of 46 years. The functional outcome was assessed with the range of motion, complications and Lysholm score.
RESULTS
All fractures was healed without displacement. The mean time to union was 7.3 weeks and degree of reduction were excellent in 11 cases and good in 9 cases and mean Lysholm score was 89 points(range, 81 to 95 points). We found no complication like limitation of range of motion of the knee, loss of reduction, irritation and migration of the hardware, and infection at last follow up.
CONCLUSION
This surgical technique provide stable fixation, allows early motion exercise by minimizing injury to extensor mechanism and reduce cosmetic problem in scar.
