Arthroscopic treatment of tibial eminence fractures using double-loop endobutton device: Surgical technique and short-term treatment outcomes.

Abstract

Objectives This study aims to explain the arthroscopic surgical technique of double-loop endobutton device for tibial eminence fractures and share the outcomes of this treatment method.Patients and methods Thirteen patients (10 males, 3 females; mean age 19.9±5.6 years; range, 14 to 34 years) with tibial eminence fractures type II, IIIa, and IIIb were analyzed retrospectively between March 2017 and March 2019. Knee laxity, Tegner Lysholm knee scores, the International Knee Documentation Committee (IKDC) scores, knee mobility, Lachman test, and bone union were analyzed after the arthroscopic fracture fixation with double-loop endobutton device at first and sixth months after surgery.Results First month mean IKDC scores were 38.0±7.0 and mean Tegner Lysholm scores were 50.3±5.8. Sixth month mean IKDC scores were 80.2±4.0 and mean Tegner Lysholm scores were 87.1±5.4. All patients showed negative Lachman test and negative pivot-shift test at final follow-up. Radiological bone union without reduction loss was also seen in all patients.ConclusionUsing double-loop endobutton device provides successful results to fix tibial eminence fractures.
