Abstract

• We have treated 22 patients of complicated patellar fracture with generally proposed fixation methods and supplementary circumferential wire loop as a checkrein or load sharing cable from Mar. 1995 to Feb. 1997 and then compared its surgical results with 15 patients of patellar fracture treated with modified tension band wiring alone in terms of functional recovery of the injured knee. The pattern of fracture was mostly comminuted(Bostman Type II), usually accompanying ipsilateral fractures with or without open wound, ligamentous injuries, or others. Although obtainning more satisfactory functional results in supplementary circumferential wire loop (68%) than control group(46.6%) in according to Lysholm and Gillquist scoring system and statistically significant difference in duration of regaining the functional arc of knee motion between two groups(p=0.007, Wilcoxon rank sum test) at 6 months postoperatively, we have found similar clinical results in two groups at 12 months follow-up(82% vs 80% in good results). Nevertheless, we thought that supplementary circumferential wire loop is one of the effective methods to improve the early surgical results of the complicated patellar fracture in respect of prompt regaining in knee motion.
• Key words: patella, complicated fracture, supplementary circumferential wire loop
