Background: Anatomical reconstruction of the anterior cruciate ligament (ACL) using the double-bundle (DB) technique is becoming increasingly popular. Despite its proved biomechanical and anatomical superiority, clinical studies have found little advantage for the DB technique. The aim of this study was therefore to evaluate whether an experienced surgeon is able to obtain his usual good results with ACL reconstruction with the single-bundle (SB) technique directly after changing to the DB technique. Patients/Material and Methods: In a prospective, non-randomised and controlled interventional study, we compared the first 19 patients in our clinic who had an anterior cruciate ligament reconstruction using the DB technique with 31 patients who underwent a SB ACL reconstruction performed by the same surgeon during the same period of investigation...

PURPOSE: The growing popularity of elite soccer among female participants has led to increased incidents of anterior cruciate ligament (ACL) ruptures. Many authors underline a positive glide after ACL reconstruction (ACLR), especially in women. In fact, an isolated intra-articular ACLR may be inadequate to control rotational instability after a combined injury of the ACL and the peripheral structures of the knee. Extra-articular procedures are sometimes used in primary cases displaying excessive antero-lateral rotatory instability...

BACKGROUND: Graft choice for anterior cruciate ligament (ACL) reconstruction is of critical importance. Various grafts have been used so far, with autografts long considered the optimal solution for the treatment of ACL-deficient knees. Limited data are available on the long-term survivorship of synthetic grafts. PURPOSE: To compare the functional outcome and survivorship of ACL reconstructions performed using the LARS (ligament augmentation and reconstruction system) ligament and the ABC (active biosynthetic composite) purely polyester ligament...

PURPOSE: Anatomically, posterior cruciate ligament (PCL) consists of two bundles, i.e. anterolateral (AL) and posteromedial (PM) bundle. Single-bundle PCL (SBPCL) reconstruction remains most popular method of reconstruction, though double-bundle PCL (DBPCL) reconstruction is more anatomical. This study was done to analyse the clinical and functional outcome after both SBPCL and DBPCL reconstructions using autologous hamstring grafts. METHODS: This was a retrospective study including patients who underwent either DBPCL or SBPCL reconstruction for chronic symptomatic PCL injury...

BACKGROUND: There is an on-going discussion whether to operatively treat combined grade II and III lesions of the medial collateral ligament (MCL) with anterior cruciate ligament (ACL) in the acute phase rather than conservative treatment of the MCL lesion with a delayed unitary ACL replacement. Another issue is the question how to technically address these MCL lesions. The aim of this study was, therefore, to analyze the results of simultaneous ACL replacement (hamstrings) in a single-bundle technique with a simultaneous MCL ligament bracing procedure...

With the increasing incidence of anterior cruciate ligament (ACL) reconstruction in women and younger patients, the optimal graft choice in the young female patient has become the subject of much debate. This study aimed to evaluate patient-reported outcomes, objective knee stability, complication rates, and the incidence of failure after ACL reconstruction using bone-patellar tendon-bone (BPTB) autograft compared with hamstring (HS) autograft in young female patients. Female patients who underwent primary ACL reconstruction with BPTB or HS autograft between ages 15 and 25 years were identified...
