Treatment of Patellar Lower Pole Fracture with Modified Titanium Cable Tension Band Plus Patellar Tibial Tunnel Steel “8” Reduction Band

Abstract

Purpose: To determine the efficacy of modified titanium tension band plus patellar tendon tunnel steel 8 “reduction band” versus titanium cable tension band fixation for the treatment of patellar lower pole fracture. Materials and Methods: 58 patients with lower patella fracture were enrolled in this study, including 30 patients treated with modified titanium cable tension band plus patellar tibial tunnel wire “8” tension band internal fixation (modified group), and 28 patients with titanium cable tension band fixation. All patients were followed up for 9∼15 months with an average of 11.6 months. Results: Knee flexion was significantly improved in the modified group than in the titanium cable tension band group (111.33 ± 13 degrees versus 98.21 ± 21.70 degrees, P = 0.004). The fracture healing time showed no significant difference. At the end of the follow-up, the improvement excellent rate was 93.33% in the modified group, and 82.14% in the titanium cable tension band group. Titanium cable tension band internal fixation loosening was found in 2 cases, including 1 case of treatment by two surgeries without loose internal fixation. Conclusions: The modified titanium cable tension band with “8” tension band fixation showed better efficacy for lower patella fractures than titanium cable tension band fixation.
