AB  - BACKGROUND: The fixation of inferior pole fractures of the patella (IPFPs) is 
      still a great challenge for surgeons. MATERIALS AND METHODS: We introduced a new 
      fixation method for IPFP fixation, that is, separate vertical wiring plus 
      bilateral anchor girdle suturing fixation (SVW-BSAG). Three finite element models 
      including the anterior tension band wiring (ATBW) model, separate vertical wiring 
      (SVW) model and SVW-BSAG model, were built to evaluate the fixation strength of 
      different fixation methods. A total of 41 consecutive patients with IPFP injury 
      were enrolled in this retrospective study, including 23 patients in the ATBW 
      group and 18 patients in the SVW-BSAG group. The operation time, radiation 
      exposure, full weight-bearing time, Bostman score, extension lag versus 
      contralateral healthy leg, Insall-Salvati ratio, and radiograph outcomes were 
      employed to assess and compare the ATBW group and SVW-BSAG group. RESULTS: The 
      finite element analysis confirmed that the SVW-BSAG fixation method was as 
      reliable as the ATBW fixation method in terms of fixed strength. Through 
      retrospective analysis, we found that there was no significant difference between 
      the SVW-BSAG and ATBW groups in age, sex, BMI, fracture side, fracture type, or 
      follow-up time. There were no significant differences between the two groups in 
      the Insall-Salvati ratio, 6-month Bostman score, and fixation failure. Compared 
      with the ATBW group, the SVW-BSAG group showed advantages in intraoperative 
      radiation exposure, full weight-bearing time, and extension lag versus the 
      contralateral healthy leg. CONCLUSION: The finite element analysis and clinical 
      results showed that SVW-BSAG fixation methods are a reliable and valuable for 
      IPFP treatment.
