Abstract

Purpose: To evaluate the feasibility and clinical effect of Krackow suturing combined with the suture bridge technique for the treatment of acute inferior pole patella fracture.

Methods: In this study, 18 patients with acute inferior pole patella fracture who received treatment using Krackow suturing combined with the suture bridge technique between January 2019 and March 2020 were retrospectively reviewed. There were 10 men and 8 women, with an average age of 50.1 years (range 24-69 years). X-ray examinations were performed to assess fracture healing and the Insall-Salvati index. The clinical effect was measured by the range of motion of the knee joint and the Böstman scale.

Results: Patients were followed up for 13-26 months, with an average follow-up period of 19.6 months. X-ray indicated that fracture union had occurred in all patients by 10.1 weeks after surgery on average (range 8-14 weeks). The mean Insall-Salvati index immediately after surgery and at the final follow-up was 0.98 ± 0.07 and 0.90 ± 0.22, respectively (P > 0.05). At the last follow-up, the mean flexion and extension ranges for the knee joint were 135.8° ± 8.8° and - 2.8° ± 3.9°, respectively, and the mean Böstman scale was 28.9 ± 1.1 points. Functional recovery was excellent in 17 patients and good in one patient, resulting in an overall good/excellent recovery rate of 100%.

Conclusions: Our results indicated that Krackow suturing combined with the suture bridge technique can achieve stable fracture fixation, provides good clinical outcomes in the treatment of acute inferior pole patella fracture, and is worthy of clinical application.
