Therapeutic efficacy of arthroscopy-assisted transosseous fixation with the Versalok suture anchor for tibial eminence fractures in adults

To investigate the clinical outcomes of arthroscopy-assisted transosseous fixation of tibial eminence fractures with the Versalok suture anchor in adults. A total of 23 adult cases of tibial eminence fractures treated between June 2016 and March 2019 were retrospectively analyzed. The results of the preoperative drawer test and Lachman test were positive. Radiography and computed tomography were performed before and after the procedure. Magnetic resonance imaging was performed in every patient after admission. Arthroscopy-assisted fracture reduction and Orthocord high-strength suture fixation with two Versalok anchors were performed in all the patients. The International Knee Documentation Committee scale and the Lysholm Knee Scoring Scale were used to evaluate outcomes during the follow-up period. Additionally, the KT-2000 knee stability test was performed. At the final follow-up, all the fractures had proceeded to bony union and no wound infection was observed. The average Lysholm Knee Score of the affected knees was 93.1 (range, 90-98), which was not significantly different from that of the healthy knees (t = 0.732, P = .132). Based on the International Knee Documentation Committee scale results, 21 patients were graded as normal and the other 2 patients were graded as nearly normal. The KT-2000 test showed that the anterior displacement of the affected side and the healthy side was less than 3.6 mm in all cases. The outcomes indicated firm fixation and good fracture healing with minimal trauma. Thus, arthroscopy-assisted transosseous fixation with Versalok suture anchors for adult tibial eminence fractures seems to have satisfactory clinical outcomes.

Automated summary

A retrospective analysis of 23 adult cases of tibial eminence fractures treated with arthroscopy-assisted transosseous fixation using Versalok suture anchors showed good fixation and fracture healing outcomes, with postoperative knee function scores comparable to healthy knees.
