BACKGROUND: This article provides a detailed narrative review on the history and current concepts surrounding ligamentous repair techniques in athletic patients. In particular, we will focus on the anterior cruciate ligament (ACL) as a case study in ligament injury and ligamentous repair techniques. PubMed (MEDLINE), EMBASE and Cochrane Library databases for papers relating to primary anterior cruciate ligament reconstruction were searched by all participating authors. All relevant historical papers were included for analysis...

Posteromedial meniscotibial ligament lesions, known as meniscal ramp lesions, are typically associated with ACL injuries, but frequently underdiagnosed. When correctly diagnosed, repair is mandatory in most cases. Retraction of the soft tissues makes it difficult to repair and leads to suture failure. Previously described techniques include all-inside and inside-out meniscal sutures, but do not ensure correct meniscotibial closure because of the soft tissue retraction. The purpose of this Technical Note is to describe a meniscal ramp lesion arthroscopic repair with an all-inside technique with the Fast-Fix 360 device, detailing the use of the accessory posteromedial portal, and the addition of an arthroscopic grasper that raises the retracted meniscotibial ligament, to allow correct fixation...

Purpose: Meniscal surgery is one of the most performed orthopaedic procedures. Because of its chondroprotective properties, meniscal repair should be attempted whenever possible. Several techniques are described in literature, e.g. all-inside repair using FasT-Fix System from Smith & Nephew. The aim of this study was to evaluate the outcome at a minimum of 12 years following meniscal repair using FasT-Fix System. Materials and Methods: Patients who underwent meniscal repair using FasT-Fix System in the time from 2001 to 2003 were analyzed...

It was in the early 1900s that anterior cruciate ligament (ACL) repair was first described with its resurgence in the mid-1900s. It however failed to gain popularity because of unsatisfactory early outcomes as a result of poorly selected patients. We describe a suture pullout technique of acute ACL repair in a carefully selected cohort of patients. Healing capabilities similar to that of the proximal medial collateral ligament have been shown in the proximal ACL avulsions. Adding microfracture of the lateral wall of the notch further enhances the healing environment by countering the synovial fluid environment...

Although anterior cruciate ligament (ACL) reconstruction remains the gold standard for the treatment of ACL tears, repair is regaining popularity as a treatment option for proximal or distal ACL avulsions. Historically, ACL repairs had poor outcomes. To remedy this, techniques were developed using graft-based augmentation but never gained widespread popularity. Recently, there has been a renewed interest in primary ligament repairs, with newer techniques incorporating modern synthetic materials to augment the repair site...

The anterior cruciate ligament is one of the six ligaments in the human knee joint that provides stability during articulations. It is relatively prone to acute and chronic injuries as compared to other ligaments. Repair and self-healing of an injured anterior cruciate ligament are time-consuming processes. For personnel resuming an active sports life, surgical repair or replacement is essential. Untreated anterior cruciate ligament tear results frequently in osteoarthritis. Therefore, understanding of the biomechanics of injury and properties of the native ligament is crucial...

Surgical repair of tendons of the foot and ankle is performed utilizing various methods, including autografts, allografts, and synthetic grafts. Artelon is a synthetic biomaterial that is fabricated from wet-spun fibers of PCL-based polyurethane urea, and has, optimal mechanical properties compared with other grafting options. Because of excellent results of Artelon in ACL reconstruction, its use was explored in 3 foot and ankle cases: repair of Achilles, posterior tibial, and peroneal tendons. Artelon has proven to be a successful alternative for tendon repairs, with all 3 cases returning to full function within 8 to 16 weeks and with no complications related to the graft...

PURPOSE: Dynamic intraligamentary stabilization (DIS) is a primary repair technique for acute anterior cruciate ligament (ACL) tears. For internal bracing of the sutured ACL, a metal spring with 8 mm maximum length change is preloaded with 60-80 N and fixed to a high-strength polyethylene braid. The bulky tibial hardware results in bone loss and may cause local discomfort with the necessity of hardware removal. The technique has been previously investigated biomechanically; however, the amount of spring shortening during movement of the knee joint is unknown...

The purpose of this study was to assess intra-articular use of a nonabsorbable braided suture tape for its biocompatibility when implanted adjacent to the native anterior cruciate ligament (ACL) in a canine model. Establishing biocompatibility of suture tape in the knee is an important foundational step for clinicians considering use of suture tape augmentation for ACL reconstruction or repair. The study hypothesis was that a nonabsorbable braided suture tape would be biocompatible in the knee with no resultant adverse functional consequences, and no significant intra-articular synovial reactions or articular cartilage degeneration attributable to direct exposure to the suture tape, whether intact or transected...

BACKGROUND: Ramp lesions were initially defined as a tear of the peripheral attachment of the posterior horn of the medial meniscus at the meniscocapsular junction. The separate biomechanical roles of the meniscocapsular and meniscotibial attachments of the posterior medial meniscus have not been fully delineated. PURPOSE: To evaluate the biomechanical effects of meniscocapsular and meniscotibial lesions of the posterior medial meniscus in anterior cruciate ligament (ACL)-deficient and ACL-reconstructed knees and the effect of repair of ramp lesions...

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...

Prior studies have not found significant differences in meniscal parameters between patients with meniscal and ligamentous injury and those without. The purpose of this study was to determine whether such relationships exist. Clinical records and magnetic resonance images of three subject groups were reviewed. Group 1 solely had meniscal tears (medial/lateral), Group 2 had meniscal tears with concurrent ACL tears, and Group 3 had healthy knees. The mean age of subjects included was 35.9 years (range 8.2-72...

BACKGROUND: Few studies have evaluated the influence of anterior cruciate ligament (ACL) reconstruction on the outcome of cartilage repair. Hypothesis/Purpose: The purpose was to investigate the association between ACL reconstruction and functional outcomes after osteochondral allograft (OCA) transplantation. The hypothesis was that patients treated with OCA transplantation who had a history of ACL reconstruction would have inferior clinical outcomes and lower osteochondral graft survivorship when compared with a matched group of patients undergoing OCA transplantation without a history of ACL reconstruction...

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...

The purpose of this study is to determine the reoperation rate following meniscal repair and the associated risk factors. The Military Health System Data Repository was queried for active duty patients between January 2009 and December 2012 undergoing meniscal repair by Current Procedural Terminology code (29882, 29883, and 27403). This cohort was then screened for subsequent procedures following the index procedure. Risk factors for reoperation were calculated using a Cox proportional hazard analysis. A total of 3259 primary meniscal repairs were identified over the study period, of which 1423 (43...

PURPOSE: Recently, it has been recognized that meniscocapsular ('ramp') lesions of the posterior one-third of the medial meniscus frequently occur during injuries causing ACL rupture, and that these lesions are easily missed at arthroscopy. Furthermore, it is clear that these lesions are biomechanically significant, adding to the deficits caused by ACL rupture, and that their repair can reverse this. The efficacy of an all inside repair technique has been questioned by some authors and by those who advocate a suture shuttle technique via an accessory posteromedial portal...

EDITORIAL
Romain Seil
Thirty-five years after their initial description, ramp lesions of the medial meniscus in anterior cruciate ligament (ACL)-deficient knees are slowly being rediscovered. Routinely repaired in open ACL and peripheral reconstructions before the era of arthroscopic ACL reconstruction, ramp lesions have been largely ignored in the last 2 decades. Following the growing number of studies analyzing the causes of residual laxity after ACL reconstructions over the last decade, ramp lesions are increasingly being implicated, and thus investigated, but remain poorly understood...

OBJECTIVE: The purpose of this study was to assess the differences between subtalar instability (STI) and lateral ankle instability (LAI) focusing on subtalar ligaments using 3-dimensional (3D) isotropic magnetic resonance imaging (MRI). METHODS: Preoperative MRIs of 10 patients with STI who failed nonoperative treatment and consequently underwent arthroscopic subtalar reconstruction were compared with preoperative MRIs of 23 patients with LAI who underwent ligament repair or reconstruction...

PURPOSE: To investigate the stabilizing effect of a lateral meniscus posterior root repair in an ACL and root deficient knee. METHODS: The hypothesis of the current study was that a sequential transection of the posterior root and the meniscofemoral ligaments in an ACL-deficient knee increases rotational instability, and conversely, a repair of the meniscus root reduces the internal tibial rotation. Therefore, eight human knee joints were tested in a robotic setup (5 N m internal torque, 50 N m anterior translation load)...
