COMPARISON OF FUNCTIONAL OUTCOME OF MODIFIED TBW VERSUS MODIFIED TBW AUGMENTED WITH CIRCUMFERENTIAL CERCLAGE WIRING IN TRANSVERSE FRACTURE OF PATELLA

Abstract

Background: The most common fracture of patella is transverse fracture of body. The gold standard treatment for displaced fracture is by tension band wiring (TBW) technique, augmentation with circumferential cerclage ss wiring has been suggested to improve the strength of the xation. Methods: The study was conducted at Nalanda Medical College, Patna during the period 2018-2020, by treating 28 patients. Group 1 (n=15) treated with modied tension band wiring (TBW) alone while as Group 2 (n=13) treated by modied TBW along with augmented circumferential cerclage ss wiring. Outcome was studied, graded and compared using the Modied Bostman Scale, union rates, and complication rates. Results: The results at nal follow up in group 1 were excellent in 10( 66.67%), good in 4(27.67%) and unsatisfactory in 1(6.67%). In group 2 the results were excellent in 8(61.54%), good in 5(38.46%) and no unsatisfactory results. Both groups have similar outcomes based on the scoring system used. The results were tested using t test and found to be different but not statistically signicant( p value- 0.469). In group one, 1(6.67%) developed deep infection and 1(6.67%) developed supercial infection. In group 2 2(15.38%) developed supercial infection, however these results are not statistically signicant (p value-0.432). Hardware irritation was seen in 3(20%) of group 1 and 3(23.07%) of group 2(p value>.05). 2(13.33%) of group 1 had implant removal during the course of follow up where as 2(15.38) in group 2 had hardware removal done. Conclusions: Modied tensioned band wiring for displaced transverse fracture of patella is an inexpensive and excellent method of treatment and the use of circumferential cerclage ss wiring along with tension band wiring for displaced transverse fractures of patella seems to have no added advantage over xation with tension band wiring alone.
