Sumario:The traditional surgical methods to the fracture of the inferior patellar fracture include steel wire tension band fixation and inferior patellar resection, which have many disadvantages. In order to overcome the disadvantages of traditional surgery, we innovated and improved the double row anchor suture bridge technology to the treat the inferior patellar fracture. This study is to investigate the method, technique and clinical efficacy of double-row anchor suture bridge technique in the treatment of inferior pole fractures of patella. Between January 2019 and March 2021, 36 patients with inferior pole fractures of patella underwent the surgery with the double-row anchor suture bridge technique. 28 injury cases were caused by falls while 8 injury cases were from car crashes. The operation time, amount of intraoperative bleeding and complications were recorded. Radiological assessments and Bostman score were performed 1, 3, and 6 months post-operation and at the most recent follow-ups. The study sample consisted of 19 males and 17 females, aged 31 to 72 years old. The operation time was (54–76) minutes. All incisions healed in 1 stage. No complications such as incision infection, flap necrosis and nerve injury occurred. Patients in this group were followed up for 10 to 18 months, with an average follow-up of 12 months. All fractures healed in 10 to 20 weeks, with an average healing time of 12 weeks. At the last follow-up, the Bostman score was (27.5 ± 3.3), excellent in 32 cases and good in 2 cases, with an excellent rate of 94.4%. The range of motion of the knee joint was (−2.6 ± 2.0)° when the knee was extended and (122 ± 5.0)° when the knee was bent. The muscle strength of quadriceps femoris was grade 5. Double-row anchor suture bridge technique is applied to inferior pole fractures of patella by virtue of its various effects, such as the complete preservation of the inferior pole fragments during the operation, satisfactory fracture reduction, firm fixation, and meeting patients’ requirements for early postoperative ambulation. In summary, double-row anchor suture bridge technique is an ideal surgical procedure for the treatment of the inferior pole fracture of patella with safety, reliability and high satisfaction.
