Augmented short undersized Hamstring Tendon Graft Hamstring with LARS?artificial ligament versus four-strand tendon in anterior cruciate ligamentreconstruction: Preliminary results

摘要

Background. - This retrospective study compares the results of reconstruction of isolated chronic anteriorcruciate ligament rupture using augmented short and small sized hamstring tendon graft with ligamentadvanced artificial reinforcement system (LARS?) versus a four-strand hamstring tendon graft (4-SHG).Our hypothesis was that postoperative knee stability after using augmented short length or small dia-meter hamstring tendon graft with LARS? artificial ligament could be significant and satisfactory morethan 4-strand hamstring tendon graft group. Materials and methods. - Between June 2007-July 2008,72 patients were divided into a LARS? augmentedgroup (n = 27) and a 4-SHG group (n = 45). Results. - Mean FU is 5 years. KT1000 examinations showed that the LARS? group had significantly lessanterior displacement than the 4-SHG group (P=0.013). IKDC score demonstrated statistically significantdifferences (P=0.05). Conclusions. - Our study indicates that early results of augmenting short length or small diameter har-vested hamstring tendons with LARS? in ACL reconstruction provides satisfactory, comparable resultsand displayed higher knee stability compared to 4-SHG group.Level of evidence. - Level III (case control study).
