A study on tibial eminence avulsion fracture treated with minimally invasive Endobutton fixation and its functional outcome

Abstract

Displaced tibial eminence avulsion fractures warrants a surgical intervention. Newer studies have indicated the superiority of arthroscopic fixation with intra articular button with its different tensioning material. Management of such patients of low socioeconomic population is a different challenge altogether in view of lack of resources, arthroscopic trained personnel and economic constraints. Authors describe a new technique of fixation using intraarticular button (Endobutton) and polyester 5 (Ethibond) in a peculiar fashion.To describe the technique and to evaluate its outcome. We aimed to determine whether this fixation method could be an optimal alternative to address this fracture in such circumstances.It is a retrospective analytical study evaluating subjective as well as objective outcome using Lachman & pivot shift test, Range of motion (ROM); functional outcome using Lysholm knee scoring scale, ability to return to work & level of satisfaction on a 10 point scale. Radiological union and limb length discrepancy (LLD) was also assessed.The study suggested that this is a simple and effective technique with acceptable results. The study also indicates that our technique has the potential to be an optimal alternative to address this fracture in the said population. Further, it should intrigue surgeons to further evaluate and adapt the technique.
