Purpose Anterior cruciate ligament (ACL) injuries are often accompanied by meniscal tears. Meniscal repair is typically performed during ACL reconstruction. However, retear of the meniscus after repair is frequent. The purpose of this study was to analyze the factors associated with meniscal healing after meniscal repair concomitant with ACL reconstruction. Materials and Methods Eighty-seven meniscal repairs in 87 patients who received meniscal repair combined with ACL reconstruction and received second-look arthroscopy at a mean of postoperatively 15...

BACKGROUND: Quantitative MR, including T1ρ mapping, has been extensively used to probe early biochemical changes in knee articular cartilage of subjects with osteoarthritis (OA) and others at risk for cartilage degeneration, such as those with anterior cruciate ligament (ACL) injury and reconstruction. However, limited studies have been performed aimed to assess the spatial location and patterns of T1ρ. In this study we used a novel voxel-based relaxometry (VBR) technique coupled with principal component analysis (PCA) to extract relevant features so as to describe regional patterns and to investigate their similarities and differences in T1ρ maps in subjects with OA and subjects six months after ACL reconstruction (ACLR)...

The menisci of the knee reduce tibiofemoral contact pressures and aid in knee lubrication and nourishment. Meniscal injury occurs in half of knees sustaining anterior cruciate ligament injury and the vast majority of tears in the medial meniscus transpire in the posterior horn region. In this study, computational multibody models of the knee were derived from medical images and passive leg motion for two female subjects. The models were validated against experimental measures available in the literature and then used to evaluate medial meniscus contact force and internal hoop tension...

BACKGROUND: Because of a reduction in the number of mechanoreceptors or alterations of their characteristics, anterior cruciate ligament (ACL) tears lead not only to mechanical instability but also to impaired proprioception. Purpose/Hypothesis: This study analyzed whether ACL tears cause a greater decrease in proprioception in injured than in uninjured knees. The hypothesis was that knee proprioception after ACL tears would decrease more in injured than in contralateral uninjured knees, regardless of the method used to measure knee proprioception...

BACKGROUND: Results of anterior cruciate ligament (ACL) reconstruction are traditionally excellent in younger and nonarthritic patients. During the past few decades, people older than 60 years have become more active than ever, with more demanding physical lifestyles. An increase also has been noted in active patients with diagnosed ACL injuries. More patients are requesting treatment for ACL deficiency in hopes of returning to preinjury levels of activity. PURPOSE: The aims of this study were to evaluate the results of ACL reconstruction in patients older than 60 years in terms of functional recovery, return to sports, and postoperative incidence of osteoarthritis and to compare their results with published results of different age groups...

OBJECTIVE: The purpose of this study was to evaluate the influence of patient age on the effects of conservative treatment of the anterior cruciate ligament (ACL). METHODS: A total of 102 consecutive patients with acute ACL injury were allowed to heal without surgery. Final magnetic resonance imaging images of the ACL were classified from grade I, indicating good morphological recovery, to grade IV, indicating poor recovery. Chi-square analysis was used to determine significant differences in the incidence of grades I and II among those less than 20 versus those 20 years or more of age...

The gold standard of anterior cruciate ligament (ACL) injuries is currently single-bundle autograft reconstruction. However, many disadvantages of reconstructive surgery exist, such as: anterior knee pain, muscle atrophy, and loss of range of motion. In addition, native kinematics are not restored, and osteoarthritis is not prevented. Finally, revision surgery, if necessary, can be problematic due to tunnel widening, tunnel malpositioning, and preexisting hardware. Ligament preservation includes preservation of native tissues in order to optimize the biologic aspects, while decreasing the invasive nature of reconstructive surgery...

Concurrent meniscal repair with anterior cruciate ligament (ACL) reconstruction has shown good clinical outcomes, but it has a considerable risk of progressing to post-traumatic osteoarthritis of the knee. Here we investigated postoperative changes in the position of the lateral meniscus (LM) and assessed the short-term clinical results after concurrent LM repair with ACL reconstruction. Twentyseven patients underwent LM repair of a peripheral longitudinal tear concomitant with ACL reconstruction. We evaluated the preoperative and postoperative values of the Lysholm score and anteroposterior instability...

BACKGROUND: Anterior cruciate ligament reconstruction (ACLR) is one of the most well studied and performed procedures in the world. Thus, it would be useful to develop a tool to predict patient outcomes post-operatively to allow clinicians to optimise management. PURPOSE: To identify and summarise factors predictive of graft failure and patient-reported outcome (PROM) measures at minimum two years after ACLR with single-bundle quadruple hamstring autograft via the anteromedial portal technique...

In a select group of patients with proximal anterior cruciate ligament (ACL) tears, primary repair can be a useful technique. Preservation of the native ACL may be advantageous for proprioceptive function and is thought to restore normal knee joint kinematics. The procedure is a less morbid and more conservative surgical approach to restore knee stability. Primary repair is preferably performed in the acute setting because of better healing capacity and tissue quality. We present the surgical technique of arthroscopic primary ACL repair with suture anchors in patients with proximal tears and excellent tissue quality...
