Clinical features of anterior cruciate ligament (ACL) injury are important for its prevention, diagnosis and treatment. However, few studies have reported such data, especially in China. The purpose of this study was to describe the clinical characteristics of ACL injury on a large cohort.

The primary objective was to calculate the rate of return to sport (RTS) following anterior cruciate ligament (ACL) reconstruction in elite athletes. Secondary objectives were to estimate the time taken to RTS, calculate rates of ACL graft rupture, evaluate postsurgical athletic performance and identify determinants of RTS.

The Royal Dutch Society for Physical Therapy (KNGF) instructed a multidisciplinary group of Dutch anterior cruciate ligament (ACL) experts to develop an evidence statement for rehabilitation after ACL reconstruction.

The aim of this study was to update our original systematic review of return to sport rates following anterior cruciate ligament (ACL) reconstruction surgery.

A controversial discussion is held on using stabilizing knee braces after anterior cruciate ligament (ACL) surgery. The current study investigated the influence of a stabilizing knee brace on results after ACL reconstruction using patellar tendon autografts.

To determine if the presence of MRI osteoarthritis (OA) features in the patellofemoral or tibiofemoral joint (i.e. bone marrow lesions, cartilage lesions, osteophytes) and/or functional impairments, 1-year following anterior cruciate ligament reconstruction (ACLR), can predict Knee injury and Osteoarthritis Outcome Score (KOOS) at 3-years.

The aim of the present study was to compare primary stability in ACL reconstruction and ultimate load to failure of a mesh augmented hamstring tendon graft fixed with two cross pins to established hamstrings and bone-patellar-tendon-bone (BTB) graft fixation methods.

STUDY DESIGN: Within and between subject cross sectional study. OBJECTIVES: To investigate symmetry in hop test performance, strength, and lower extremity kinematics 6-9 months post anterior cruciate ligament reconstruction (ACLR). BACKGROUND: Despite the extensive body of literature in persons following ACLR, no study has comprehensively evaluated measures of strength, lower extremity kinematics and functional performance of hop tests in this population. METHODS: 22 men (age, 28.8± 11.2 years) 6-9 months (7.01±0.93) following ACLR using a bone-patella tendon bone autograft and 22 healthy men (24.8 ± 9.1 years) participated. Participants completed a self-reported questionnaire and underwent isokinetic strength testing and functional and kinematic assessment of the single, triple, and crossover hop tests. Two-way ANOVAs were used to test for differences between the ACLR group and the control group and between the two lower extremities of the ACLR group. RESULTS: Compared to the control group, the ACLR group had greater isokinetic knee extension torque deficits at all speeds (p≤0.001) and greater performance asymmetry for all 3 hop tests (p<0.001). Compared to the intact lower extremity, the involved lower extremity of the ACLR group exhibited less ankle dorsiflexion and knee flexion at propulsion (p≤0.014) and landing phases (p≤0.032). When compared to the control group the involved lower extremity exhibited less ankle dorsiflexion in the propulsion phase (p<0.001) but higher hip flexion in the landing phase (p=0.014). CONCLUSION: Patients following ACLR demonstrate functional hop and isokinetic knee extension deficits as well as kinematic differences during the propulsion and landing phases of the hop tests at 6-9 months after surgery.J Orthop Sports Phys Ther.

There has been an increased interest in the quantification of the knee laxity secondary to anterior cruciate ligament (ACL) injury. In clinical practice, the diagnosis is performed by clinical examination and magnetic resonance imaging analysis and confirmed arthroscopically. The pivot shift phenomenon has been identified as one of the essential signs of functional ACL insufficiency. A reliable system to adequately assess patients with ACL injury, quantifying the pivot shift test outcome, is needed. Several studies have been conducted in this regard but the proposed methods remain confined to a research area. The goal of this article is to summarize the actual knowledge and current concepts.

Rehabilitation after anterior cruciate ligament (ACL) reconstruction should consider control of postoperative pain and swelling, protection of the healing graft, restoration of full range of motion symmetric to the contralateral knee, strengthening of the muscles that stabilize the knee, hip, and trunk, enhancing neuromuscular control, and a gradual progression to functional activities that are required for return to sports. The effects of concomitant injuries and surgical procedures must also be considered in planning an individualized rehabilitation program. This article provides an overview, discusses our experience, and makes recommendations for rehabilitation after anatomic ACL reconstruction rehabilitation.
