The assessment of graft stability in ACL reconstruction with two different techniques (endobutton vs. crosspin) and the comparative evaluation of the results of the two techniques.

From October 2005 until May 2009, 69 patients underwent ACL reconstruction with the above-mentioned techniques by two surgeons; follow-up examinations took place after a minimum of two (2) years. Postoperative radiographic and clinical assessment were carried out and Lysholm, Tenger and IKDC scores were obtained at 3, 6, 12 and 24 months; stability was checked by KT-1000 arthrometer. Clinical evaluation by Lachman and pivot shift was normal or near-normal in 65 patients. No significant differences were found both as regards the KT-1000 (1.0 mm less with the cross-pin technique) and as regards the subjective variables (the endobutton having a slight advantage). Mean postoperative IKDC evaluation was 87.4 vs. 85.3, while Lysholm was 89 vs. 86. Two patients underwent revision after a new traumatic incidence and one displayed a new meniscal lesion, which was treated accordingly. The vast majority of the patients returned to their previous occupational activities and social life (overall patient satisfaction was at 88.2 vs. 85.4).

Both the endobutton and the crosspin techniques proved to be reliable fixation methods for the treatment of ACL ruptures using the hamstrigs tendons; both methods provided safe fixation even in cases when back wall blow had occurred
