ACL Repair

William T Wilson, Graeme P Hopper, Paul A Byrne, Gordon M MacKay
BACKGROUND: Anterior cruciate ligament (ACL) reconstruction using tendon or ligament autograft is the gold standard surgical treatment for acute ruptures; however, this is still associated with subsequent problems and variable outcomes. Renewed interest in healing of injured ACL tissue has led to new surgical repair techniques. CASE DESCRIPTION: We report the case of one of the first patients to undergo this novel procedure of ACL repair with internal bracing. An internal brace is a bridging concept using braided suture tape and knotless bone anchors to reinforce ligament strength...

Over the last century, many surgical treatments have been developed in the orthopedic field, including treatments of anterior cruciate ligament (ACL) injuries. These treatments ideally evolve in a process of trial and error with prospective comparison of new treatments to the current treatment standard. However, these evolutions are sometimes not linear and periodically undergo paradigm shifts. In this article, we review the evolution of ACL treatment and explain how it underwent a paradigm shift. Open primary ACL repair was the most common treatment in the 1970s and 1980s, but because multiple studies noted deterioration of outcomes at mid-term follow-up, in addition to several randomized clinical trials (RCTs) that noted better outcomes following ACL reconstruction, the open primary repair technique was abandoned...

INTRODUCTION: Femoral nerve block (FNB) is considered as a major advance in anterior cruciate ligament (ACL) reconstruction as it reduces the need for parenteral opioids. However, the incidence of transient or even permanent neurological deficits due to the FNB is estimated at 1.94% after knee surgery. The primary objective of this study was to compare local infiltration analgesia (LIA) to FNB during ACL reconstruction procedures. The study hypothesis was that LIA was not less effective than FNB on early postoperative pain...

Animal joints are valuable proxies for those of humans in biomechanical studies, however commonly used quadruped knees differ greatly from human knees in scale and morphometry. To test the suitability of the cervine stifle joint (deer knee) as a laboratory model, gross morphometry, ACL cross section, and ACL rupture strength were measured and compared to values previously reported for the knees of humans and commonly studied animals. Twelve knee joints from wild white-tailed deer were tested. Several morphometry parameters, including bicondylar width (53...

Lesions of the anterior cruciate ligament (ACL) are common; the current gold standard of treatment for such lesions is ACL reconstruction. Tibial-sided soft-tissue avulsion is a rare subtype of ACL injuries. Unlike femoral-sided ACL repair, surgery for acute tibial-sided ACL ruptures has been neither reported nor described. This technical note presents a method for primary anatomic ACL reinsertion for an acute distal soft-tissue avulsion-type ACL injury, using a transosseous pull-out repair technique. Our technique, as an alternative to reconstruction, has the potential to enhance healing due to marrow stimulation (tibial tunneling)...

Tibial plateau fractures are a heterogeneous group of lesions with multiple fracture patterns. They are often associated with soft tissue injuries, the lateral meniscus and the anterior cruciate ligament (ACL) being the most common structures affected. The purpose of this article is to present a case series of an often missed unusual injury pattern that consists on the association of a large anteromedial tibial plateau fracture with a posterolateral (PL) knee corner injury without involvement of the cruciate ligaments...

BACKGROUND: Anterior cruciate ligament (ACL) repair is increasingly performed on an out-patient basis. In France, however, concern about post-operative pain remains a strong barrier to out-patient ACL repair. The primary objective of this study was to compare post-operative pain after ACL repair as out-patient versus in-patient surgery. The secondary objectives were to assess the time-course of post-operative pain and to identify factors associated with pain intensity. MATERIAL AND METHODS: A multicentre, prospective, comparative, non-randomised study was conducted in France for the French Society for Arthroscopy (SFA) symposium...

Acellular xenogeneic tissues have the potential to provide 'off-the-shelf' grafts for anterior cruciate ligament (ACL) repair. To ensure that such grafts are sterile following packaging, it is desirable to use terminal sterilization methods. Here, the effects of gamma and electron beam irradiation on the biological and biomechanical properties of a previously developed acellular porcine superflexor tendon (pSFT) were investigated. Irradiation following treatment with peracetic acid was compared to peracetic acid treatment alone and the stability of grafts following long-term storage assessed...

Mid-substance rupture of the canine cranial cruciate ligament rupture (CR) and associated stifle osteoarthritis (OA) is an important veterinary health problem. CR causes stifle joint instability and contralateral CR often develops. The dog is an important model for human anterior cruciate ligament (ACL) rupture, where rupture of graft repair or the contralateral ACL is also common. This suggests that both genetic and environmental factors may increase ligament rupture risk. We investigated use of bone marrow-derived mesenchymal stem cells (BM-MSCs) to reduce systemic and stifle joint inflammatory responses in dogs with CR...

The biodegradable silk-based scaffold with unique mechanical property and biocompatibility represents a favorable ligamentous graft for tissue-engineering anterior cruciate ligament (ACL) reconstruction. However, the low efficiency of ligament-bone interface restoration barriers the isotropic silk graft to common ACL therapeutics. To enhance the regeneration of the silk-mediated interface, we developed a specialized stratification approach implementing a sequential modification on isotropic silk to constitute a triphasic silk-based graft in which three regions respectively referring to ligament, cartilage and bone layers of interface were divided, followed by respective biomaterial coating...

PURPOSE: The purpose of the present study is the comparison of acute ACL reconstruction with or without meniscus repair within 48 h after injury and a delayed surgery during the inflammation-free interval. It was hypothesized that acute ACL reconstruction results in inferior patient reported outcomes and higher frequency of range of motion deficits. METHODS: The effect of acute (within 48 h) and delayed (during the inflammation-free interval) ACL surgery was prospectively studied on 160 consecutive patients with ACL injury between January 2010 and December 2011...

BACKGROUND: Arthroscopically assisted anterior cruciate ligament (ACL) reconstruction is a common orthopaedic procedure. Graft failure after reconstruction remains a devastating complication, often requiring revision surgery and less aggressive or modified rehabilitation. Worse functional and patient-reported outcomes are reported compared with primary reconstruction. Moreover, both rates and risk factors for revision are variable and inconsistent within the literature. PURPOSE: To determine the rate of revision surgery after ACL reconstruction in a large cohort of patients, to assess the influence of patient characteristics on the odds of revision, and to compare revision rates between active-duty military members and non-active-duty beneficiaries...

Meniscal ramp lesions are more frequently associated with anterior cruciate ligament (ACL) injuries than previously recognized. Some authors suggest that this entity results from disruption of the meniscotibial ligaments of the posterior horn of the medial meniscus, whereas others support the idea that it is created by a tear of the peripheral attachment of the posterior horn of the medial meniscus. Magnetic resonance imaging (MRI) scans have been reported to have a low sensitivity, and consequently, ramp lesions often go undiagnosed...

BACKGROUND: Patients often ask their doctors when they can safely return to driving after orthopaedic injuries and procedures, but the data regarding this topic are diverse and sometimes conflicting. Some studies provide observer-reported outcome measures, such as brake response time or simulators, to estimate when patients can safely resume driving after surgery, and patient survey data describing when patients report a return to driving, but they do not all agree. We performed a systematic review and quality appraisal for available data regarding when patients are safe to resume driving after common orthopaedic surgeries and injuries affecting the ability to drive...

PURPOSE: The purpose of the present study was to biomechanically compare three different posterior meniscal root repair techniques. Transtibial fixation of a posterior meniscus root tear (PMRT) combined with an anterior cruciate ligament (ACL) reconstruction via one tunnel only shows similar properties in terms of cyclic loading and load to failure compared with direct anchor fixation. METHODS: Twenty-eight porcine knees were randomly assigned to 4 groups (n = 7 each): (1) native posterior meniscal root, (2) suture anchor repair, (3) refixation via a tibial ACL tunnel in combination with an interference screw fixation of the ACL graft, and (4) refixation via a tibial ACL tunnel in combination with an interference screw fixation of the ACL graft with an additional extracortical button fixation...
