Abstract:[Objective] To investigate the clinical outcomes of modified 8-figure double suture loop for fixation of type II tibial interspi-nal avulsion fracture under arthroscope. [Methods] A retrospective study was conducted on 17 patients who underwent abovesaid proce-dures for Meyers-Mckeever type II tibial interspinal fracture under arthroscope from October 2015 to May 2020. The clinical and imagingdocuments were evaluated. [Results] All patients were successfully operated without serious complications, and followed up for (18.5±6.9)months in a mean. With time preoperatively, 3 months postoperatively and the last follow-up, the VAS score decreased significantly [(6.8±0.8), (2.3±0.5), (0.9±07), P＜0.001], while the Lysholm score [(51.9±4.2), (81.3±1.4), (91.2±2.0), P＜0.001], IKDC scores [(53.4±2.9), (79.7±2.8), (89.5±2.4), P＜0.001], and ROM [(67.6±1.1)°, (102.2±3.8)°, (124.1±1.0)°, P＜0.001] increased significantly. In addition, the knee laxi-ty in terms of anterior drawer test and Lachman test were also significantly improved (P＜0.05). Regarding imaging, all patients got fracturereduction excellent, with the mean fracture healing time of (11.2±0.8) weeks. [Conclusion] The modified 8-figure double suture loop fixa-tion under arthroscope does achieve anatomical reduction and firm fixation of Meyes-McKeever type II tibial interspinal fractures with satis-factory clinical consequences.
