Objective: To investigate the effectiveness of the Krackow suture of patellar tendon with vertical fixation through bone tunnels combined with Kirschner wire tension band in the treatment of comminuted fractures of the inferior pole of the patella. Methods: >0.05). The operation time, intraoperative blood loss, incision length, time to postoperative full weight-bearing, fracture healing time, and postoperative complications were recorded and compared between the two groups. Anterior knee pain was assessed using the VAS before surgery, at 1 week and 1 month after surgery, and at last follow-up. Knee range of motion was measured before surgery, at 1 and 3 months after surgery, and at last follow-up. At last follow-up, the Insall-Salvati index was measured to assess patellar height, and knee function was evaluated using the Bostman score for patellar fractures. Results: <0.05). Conclusion: Compared with conventional Kirschner wire tension band fixation, Krackow suture of patellar tendon with vertical fixation through bone tunnels combined with Kirschner wire tension band fixation provides satisfactory fracture reduction and reliable fixation, facilitates early functional rehabilitation, and is associated with a lower risk of internal fixation failure. It may therefore serve as a safe and reliable fixation option for comminuted fractures of the inferior pole of the patella.
