Abstract:
Objective:To evaluate the clinical efficacy of cannulated screws combined with suture anchor in the treatment of comminuted patellar fractures.Methods:A retrospective study was conducted to analyze the data of 72 patients who had been admitted to Department of Orthopaedics, The Second Hospital of Shanxi Medical University for comminuted patellar fractures between January 2020 and June 2023. The patients were divided into 2 groups based on the surgical techniques used. In group A of 34 patients subjected to fixation using cannulated screws combined with suture anchors, there were 22 males and 12 females with an age of 49 (39, 58) years, and 7 cases of AO type 34-C2 and 27 cases of AO type 34-C3. In group B of 38 patients subjected to fixation using cannulated screws combined with titanium cables, there were 19 males and 19 females with an age of 55 (40, 62) years, and 11 cases of AO type 34-C2 and 27 cases of AO type 34-C3. Comparisons were made between the 2 groups regarding general preoperative data, postoperative range of knee motion, fracture healing time, complications, soft tissue irritation, secondary surgery, postoperative pain assessed by visual analogue scale (VAS), postoperative Bostman knee score, and postoperative Levack knee score.Results:The 2 groups were comparable because there were no statistically significant differences in the general preoperative data and follow-up time between them ( P>0.05). There were no statistically significant differences between the 2 groups either in postoperative range of knee motion, fracture healing time, or Bostman knee score or Levack knee score at the last follow-up (all P>0.05). In group A, the VAS pain score and the rate of soft tissue irritation at the last follow-up were respectively 0.0 (0.0, 1.0) and 0% (0/34), significantly lower than those in group B [1.0 (0.0, 1.3) and 15.8% (6/38)] ( P<0.05). The overall incidence of complications and secondary surgery rate in group A were respectively 5.9% (2/34) and 2.9% (1/34), lower than those in group B [21.1% (8/38) and 15.8% (6/38)], but showing no statistically significant difference between the 2 groups ( P>0.05). Conclusions:In the treatment of comminuted patellar fractures, fixation using cannulated screws combined with both titanium cables and suture anchors can lead to comparable clinical efficacy, but fixation using cannulated screws and suture anchors can reduce soft tissue irritation, alleviate pain, and improve the quality of life of patients.
