Arthroscopic-assisted reduction and stabilization of transverse fractures of the patella.

Abstract

Most patellar fractures are transverse involving the central third. Open reduction and stabilization of transverse patellar fractures is indicated if there is more than 2-3 mm of fragment separation and/or articular incongruity. Arthroscopic-assisted reduction and stabilization of displaced fractures of the patella had been reported as an alternative to open technique. The aim of this study was to report the results of arthroscopic-assisted reduction and fixation of displaced transverse fractures of the patella. Fourteen patients with 14 displaced transverse fractures of the patella were included in this prospective study. Patients were treated by arthroscopic-assisted closed reduction of the fracture with percutaneous screw fixation. Patients were followed up for a mean period of 26 months. All patients were males with an average age of 34 years. All fractures united in a mean period of 7 weeks. Twelve patients regained full knee range of motion and two patients had 10 degrees loss of full flexion. All patients regained full knee extension. Thigh muscle wasting was observed in nine patients with a mean value of 0.8 cm. The mean final Lysholm score was 93. Arthroscopic-assisted reduction and percutaneous screw fixation is an appropriate technique for displaced transverse patellar fractures without major separation or comminution. It offers good functional outcome with minimal complications.
