Abstract:[Objective] To compare the clinical efficiency of Ethibond suture versus steel wire tension band for fixation of patellar frac-ture. [Methods] A retrospective study was conducted on 41 patients who received open reduction and internal fixation of patellar fracture inour department from November 2015 to December 2021. According to the doctor-patient communication, 23 patients had the fracture fixedwith Ethibond suture tension band (the suture group), while the other 18 cases were with conventional steel wire tension band (the wiregroup). The perioperative period, follow-up results and imaging data of the two groups were compared. [Results] There were no significantdifferences between the two groups in terms of operation time [(58.0±2.0) min vs (57.2±2.3) min, P＞0.05], the total length of incision [(7.8±0.3) cm vs (8.0±0.5) cm, P＞0.05], intraoperative blood loss [(60.4±2.0) ml vs (55.6±2.4) ml, P＞0.05], incision healing grade [A/B/C, (22/1/0)vs (16/2/0), P＞0.05] and hospital stay [(11.0±0.6) days vs (12.5±0.7) day, P＞0.05]. All of them were followed up for (17.2±1.0) months on amean, and there was no significant difference in the time to return to full weight-bearing between the two groups (P＞0.05). The VAS scoresdecreased significantly (P＜0.05), while the Kujala, Lysholm and Bostman scores, as well as knee extensity-flexion ROM significantly in-creased over time in both groups (P＜0.05), whereas which proved not statistically significant between the two groups at any time points ac-cordingly (P＞0.05). In terms of imaging, there were no significant differences in the fracture reduction quality, Insall-Salvati index and frac-ture healing time between the two groups (P＞0.05). [Conclusion] The Ethibond suture tension band for fixation of patella fracture doesachieve the same clinical efficacy as steel wire tension band fixation, with good safety. Therefore, the suture tension band may replace thetraditional steel wire tension fixation.
