Abstract: Objective   To investigate the clinical efficacy of Krackow suture combined with suture bridge technique in the treatment of children's inferior patellar fracture.   Methods    Nine children with inferior patellar fracture admitted from January 2017 to June 2022 were treated with Krackow suture and suture bridge technology to fix the patellar inferior pole bone block. Early postoperative rehabilitation exercise were performed. The outcome measures included complications, fracture healing time, knee pain, range of motion (ROM) and Bostman score. Results All patients were followed up for an average of 12.6 months. No wound infection, internal fixation failure, nonunion of fracture occurred after operation. Fracture healing time were (3.1±0.1) months. The Bostman score of the knee joint was (29.1±1.1), and the VAS score was (0.2± 0.4).    Conclusions    The Krackow suture method combined with suture bridge technique in the treatment of children's inferior patellar fracture is simple in operation and reliable in fixation, which is conducive to early functional exercise and does not require secondary internal fixation. It is widely applicable to children's patellar lower pole fracture and is worthy of clinical promotion.
