A retrospective comparison of the modified tension band technique and the parallel titanium cannulated lag screw technique in transverse patella fracture / 中华创伤杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>To compare efficacy between the modified tension band technique and the parallel titanium cannulated lag screw technique for the transverse patella fracture.</p><p><b>METHODS</b>Seventy-two patients were retrospectively analyzed aged 22 to 79 years (mean, 55.6 years) with transverse patella fractures, among whom 37 patients underwent the modified tension band and 35 patients received the titanium cannulated lag screw. Patients were followed up for 1-3 years. We analyzed the difference of operation time, complications, fracture reduction, fracture healing time, and the Iowa score for knee function between both groups.</p><p><b>RESULTS</b>In modified tension band group, five patients had skin irritation and seven suffered wire migration, two of whom required a second operation. In comparison, there were no complications in the titanium cannulated lag screw group, which also had a higher fracture reduction rate and less operation time.</p><p><b>CONCLUSION</b>The parallel titanium cannulated lag screw technique has superior results and should be considered as an alternative method to treat transverse patella fracture.</p>
