BACKGROUND: Combined rupture of the anterior cruciate ligament (ACL) and patella tendon (PT) is a rare injury pattern. Currently little evidence exists to help guide management decisions for these patients. METHODS: A systematic literature search was conducted using PubMed (MEDLINE) and Scopus (EMBASE, MEDLINE) for all articles reporting on combined rupture of the anterior cruciate ligament (ACL) and patella tendon (PT). The characteristic injury mechanisms, common presentation findings and outcomes of simultaneous and staged treatment strategies were determined to provide guidance for the management of this uncommon injury pattern...

BACKGROUND: The anterior cruciate ligament-deficient (ACLD) knee requires appropriate treatment for the patient to return to sports. The purpose of this study was to clarify the kinematics of the anterior cruciate ligament-deficient knee in squatting motion before and after double-bundle anterior cruciate ligament reconstruction (DB-ACLR) using a 2D/3D registration technique. METHODS: The subjects of this study were 10 men with confirmed unilateral ACL rupture who underwent DB-ACLR...

The rate of anterior cruciate ligament (ACL) ruptures diagnosed among the pediatric and adolescent population is increasing. The rise in ACL injuries may be attributed to earlier sports specialization, year-round sports participation, increased awareness, and improved ability to diagnose the injury. Treatment options for pediatric or adolescent ACL injuries include nonoperative conservative treatment, ACL repair, or various techniques for ACL reconstruction. The best course of treatment for ACL rupture in young patients continues to be debated...

Knee instability following anterior cruciate ligament (ACL) rupture compromises function and increases risk of injury to the cartilage and menisci. To understand the biomechanical function of the ACL, previous studies have primarily reported the net change in tibial position in response to multiplanar torques, which generate knee instability. In contrast, we retrospectively analyzed a cohort of 13 consecutively tested cadaveric knees and found distinct motion patterns, defined as the motion of the tibia as it translates and rotates from its unloaded, initial position to its loaded, final position...

One of the most common injuries of the knee joint is a rupture of the anterior cruciate ligament (ACL). Most authors believe that early rehabilitation of patients after ACL reconstruction promotes better treatment outcomes. Less is known about the influence of the time that passes from injury to surgical reconstruction. Therefore, the goal of this study was to assess the dependence of treatment outcomes of ACL on injury-to-reconstruction and reconstruction-to-rehabilitation time lags. The study included 30 patients of the mean age 34 ± 7 years with trauma-related rupture of ACL and its surgical reconstruction...

PURPOSE: Failure to reconstruct the natural footprints of the ruptured anterior cruciate ligament (ACL) may lead to premature graft-failure. Therefore, precise analyses of insertion site anatomy and inter-individual variations of the morphology of the ACL are highly important to facilitate optimal individualized graft placement. Therefore, the purpose of this study was to analyze the inter-individual variation of the morphology of the femoral and tibial ACL footprints. METHODS: Thirty subjects with an intact ACL were included in this study for MR imaging of their knee joint...

Our previous studies used tibial compression overload to induce anterior cruciate ligament (ACL) rupture in mice, while others have applied similar or greater compressive magnitudes without injury. The causes of these differences in injury threshold are not known. In this study, we compared knee injury thresholds using a "prone configuration" and a "supine configuration" that differed with respect to hip, knee, and ankle flexion, and utilized different fixtures to stabilize the knee. Right limbs of female and male C57BL/6 mice were loaded using the prone configuration, while left limbs were loaded using the supine configuration...

BACKGROUND: Anterior cruciate ligament (ACL) reconstruction is today's surgical gold standard for ACL rupture. Although it provides satisfactory results, not all patients return to their previous activity level and moreover, early posttraumatic osteoarthritis is not prevented. As such, a renewed interest has emerged in ACL suture repair combined with dynamic augmentation. Compared to ACL reconstruction, the hypothesized advantages of ACL suture repair are earlier return to sports, reduction of early posttraumatic osteoarthritis and preservation of the patient's native ACL tissue and proprioceptive envelope of the knee...

BACKGROUND: Partial anterior cruciate ligament (p-ACL) ruptures are a common injury of athletes. However, few preclinical models have investigated the natural history and treatment of p-ACL injuries. PURPOSE: To (1) demonstrate whether a controlled p-ACL injury model (anteromedial band transection) develops progressive gross morphological and histological posttraumatic osteoarthritis (PTOA)-like changes at 20 and 40 weeks after the injury and (2) investigate the efficacy of repeated (0, 5, 10, and 15 weeks) intra-articular injections of methylprednisolone acetate (MPA; 80 mg/mL) in the mitigation of potential PTOA-like changes after p-ACL transection...

BACKGROUND: The incidence of anterior cruciate ligament (ACL) ruptures is 2 to 4 times higher in female athletes as compared with their male counterparts. As a result, a number of recent studies have addressed the hypothesis that female and male patients sustain ACL injuries via different mechanisms. The efficacy of prevention programs may be improved by a better understanding of whether there are differences in the injury mechanism between sexes. Hypothesis/Purpose: To compare knee positions at the time of a noncontact ACL injury between sexes...

Rupture of the anterior cruciate ligament (ACL) is a common sports injury. Shear forces can damage the articular cartilage and lead to early osteoarthritis. Ligamentary stabilisation of the knee is necessary. Today, arthroscopic ACL repair is a standard knee procedure. Transplant fixation is often performed using implants, e.g. interference screws. The foreign material-free procedure using the Felmet technique enables biological, mechanically stable fixation of the hamstring tendon graft. We demonstrate the surgical technique, including meniscus suture and a video case study...

Treatment of tibial plateau fractures associated with anterior cruciate ligament (ACL) injuries can be challenging. Maintaining the joint surface and axis are two main principles for the management of patients with tibial plateau fractures. Herein, we describe a patient with tibial plateau fracture of Schatzker type VI associated with complete ACL rupture. Although in a two-stage reconstruction surgery for treatment of its rupture seem to be accepted by most orthopaedic surgeons in cases of ACL injuries, we treated our patient with ORIF in a one-stage ACL reconstruction surgery...
