BACKGROUND: Additional high-quality prospective studies are needed to better define the objective criteria used in relation to return-to-sport decisions after synthetic (ligament advanced reinforcement system [LARS]) and autograft (hamstring tendon [2ST/2GR]) anterior cruciate ligament (ACL) reconstruction in active populations. PURPOSE: To prospectively investigate and describe the recovery of objective clinical outcomes after autograft (2ST/2GR) and synthetic (LARS) ACL reconstructions, as well as to investigate the relationship between these clinimetric test outcomes and return-to-sport activity (Tegner activity scale [TAS] score) at 12 and 24 months postoperatively...

BACKGROUND: Few studies have compared clinical and radiological outcomes after hamstring anterior cruciate ligament (ACL) reconstruction with fixed-loop and adjustable-loop cortical suspension devices. PURPOSE/HYPOTHESIS: The purpose of this retrospective study was to compare clinical outcomes and tunnel widening after hamstring ACL reconstructions with fixed- and adjustable-loop cortical suspension devices. The hypothesis was that compared with femoral graft fixation with the fixed-loop device, fixation with the adjustable-loop device would show similar clinical outcomes and would result in less tunnel widening after hamstring ACL reconstruction...

Suspensory femoral fixation of anterior cruciate ligament (ACL) grafts with fixed loop button and variable loop button devices has gained popularity for ACL reconstruction. This study examined these 2 methods of fixation to determine their effect on graft laxity and patient-reported outcome scores. A database search was performed to identify patients who had undergone ACL reconstruction with either a fixed loop or a variable loop button technique performed by the primary surgeon. Lysholm, Tegner, and 12-Item Short Form Health Survey scores were obtained, and KT-1000 knee ligament arthrometer (MEDmetric, San Diego, California) mechanical knee testing was performed...

PURPOSE: Flexion instability following total knee arthroplasty (TKA) is a common indication of early revision. The association between the objective anteroposterior (AP) laxity direction in mid-range flexion and the subjective healing of instability remains unclear; thus, this study aimed to clarify this association. METHODS: In this study, 110 knees (74 females, 92 knees; 16 males, 18 knees) with medial pivot implants were examined with a median age of 79 (range 60-92) years for a median follow-up duration of 22 (range 6-125) months...

BACKGROUND: The main option to perform an anatomic anterior cruciate ligament (ACL) reconstruction is the anteromedial portal (AMP) technique. It has several reported complications (iatrogenic chondral injury, posterior-wall blowout, short sockets, increased risk of injury to common peroneal nerve). In an attempt to avoid these complications the outside-in (OI) technique was revived with the addition of a retrodrill. The aim of this study is to evaluate the clinical and arthrometric outcomes of a series of anatomical OI single bundle ACL reconstruction using a retrodrill...

BACKGROUND: Anterior cruciate ligament (ACL) tears in children are increasingly common and present difficult treatment decisions due to the risk of growth disturbance. Although open primary ACL repair was abandoned in the historical literature, recent studies have suggested that there is a role for arthroscopic primary repair in patients with proximal tears. METHODS: This is a retrospective review of five consecutive patients aged 9.2years (range 8 to 10) who underwent suture anchor ACL reinsertion...

BACKGROUND: Dynamic augmentation of anterior cruciate ligament tears seems to reduce anteroposterior knee translation close to the pre-injury level. The aim of the present study is to biomechanically investigate the course of translation during a simulated early post-operative phase. It is hypothesized that anteroposterior translation is maintained at the immediate post-operative level over a simulated rehabilitation period of 50'000 gait cycles. METHODS: Eight fresh-frozen human cadaveric knee joints from donors with a mean age of 35...

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...
