Abstract
BACKGROUND: Comminuted patella fractures place high demands on surgeons' surgical skills. We used a double-suture cerclage reduction with Nice knots as an intra-operative reduction technique to displaced comminuted patella fractures. METHODS: Patients were divided into two groups by whether or not an intra-operative suture cerclage reduction technique was used. Fragments count, surgical time, quality of the reduction, and fracture healing time were recorded. The postoperative function was assessed by Böstman score and range of motion. RESULTS: With the inclusion and exclusion criteria, 48 patients we included in the cohort between Sept. 2016 and Oct. 2021. The double-suture cerclage reduction technique with a Nice knot achieved a satisfactory reduction. When the number of fragments was over 5, this technique showed significant advantages in saving surgery time. CONCLUSIONS: In this study, the double-suture cerclage reduction technique combined with the Nice knot shows significant advantages for displaced highly comminuted patella fractures. This technique simplifies the operation and saves surgical time, which is helpful for clinical practice.
