| Abstract: | BackgroundA variety of different techniques or methods for treatment of tibial eminence fracture (TEF) have been reported, but there is still controversy on the optimum choice for treating TEFs. The aim of the current work was to compare the clinical outcomes of arthroscopic cannulated screw fixation and a new arthroscopic anchor fixation technique for tibial eminence fracture.MethodsWe included 69 isolated tibial eminence fracture patients from June 2012 to February 2017; 36 patients received the cannulated screw fixation and 33 received the transosseous anchor knot (TAK) fixation under arthroscopy. The two techniques were performed by two different high-volume surgeons. The clinical efficacies of the two techniques were assessed by radiographs, extension deficit, flexion deficit, anterior drawer test (ADT), Lachman test, Lysholm scores and International Knee Documentation Committee (IKDC) scores in follow ups.ResultsPatients were followed up for 35.8 months on average (range, 24–54 months). There were 40 (58%) males and 29 (42%) females included, and four (6%) patients were ＜18 years old. Asymptomatic grade II laxity was found in two patients in the CS group and three patients in the TAK group from the results of Lachman test. Postoperative radiographs in all patients showed anatomic reductions and bony unions were achieved within 12 weeks. There were no significant differences in extension deficit, flexion deficit, ADT, Lachman test, Lysholm scores and IKDC scores between groups (P > 0.05).ConclusionsThe TAK technique shows satisfactory clinical and radiological outcomes equal to the cannulated screw fixation, which is applicable for TEFs as a reliable effective method. |
