Injuries of the anterior cruciate ligament are currently treated primarily with the use of hamstring graft with a wide range of different techniques and fixation systems for anterior cruciate ligament in reducing patient morbidity. We report the case of a female patient aged 42 that suffered an anterior cruciate ligament rupture and was treated with anterior cruciate ligament reconstruction with hamstring autograft with femoral fixation with bio-absorbable cross-pin and tibial fixation with bio-absorbable screw...

BACKGROUND: Weighted gait increases internal knee extension moment impulses (KEMI) in the anterior cruciate ligament-reconstructed (ACLR) limb; however, limb differences persist. HYPOTHESES: (1) KEMI during normal gait will influence KEMI during weighted gait and (2) peak knee extension (PKE) torque and time to reach PKE torque will predict KEMI during gait tasks. STUDY DESIGN: Descriptive laboratory study. METHODS: Twenty-four women and 14 men completed 3 gait tasks (unweighted, vest, sled) and strength testing after discharge from rehabilitation and clearance to return to sports...

PURPOSE: There are few descriptions of outcomes after posterior cruciate ligament (PCL) reconstruction in the literature due to the rarity of this type of knee injury. Since 2005, the Danish Knee Ligament Reconstruction Registry (DKRR) has monitored outcomes of PCL reconstructions. This study describes the epidemiology of PCL reconstruction and subsequent outcomes in a Danish population. METHODS: Of 23,253 knee ligament reconstructions performed in 2005-2015, 581 were registered as PCL reconstructions in the DKRR...

BACKGROUND: Remnant tissue preservation may be important in improving graft healing after anterior cruciate ligament (ACL) reconstruction, but it has yet to be established whether remnant tissue preservation improves the control of pivot-shift laxity. HYPOTHESIS: The amount of ACL graft coverage with preserved remnant tissue improves the control of pivot-shift laxity, as qualitatively determined with an electromagnetic device. STUDY DESIGN: Cohort study; Level of evidence, 3...

BACKGROUND: Harvested hamstring tendon length has received scant attention in published anterior cruciate ligament (ACL) reconstruction literature, yet length can limit the ability to increase graft diameter by folding the tendon over more than once. Indeed, some ultrashort tendons may be too short to yield a clinically useful graft after being folded over just once. Ultimately, the total length of a harvested hamstring tendon may depend on the length of the tendon distal to its musculotendinous (MT) junction...

Chao Wan, Zhixiu Hao, Zhichang Li, Jianhao Lin
As one of the most frequently used grafts in anterior cruciate ligament (ACL) reconstruction, hamstring tendon (HT) grafts are prepared with different lengths and fixed by specific fixations in knee joints. However, there are incomplete studies to investigate both the joint kinematics and graft biomechanics in the ACL reconstructions with different HT graft lengths. In this paper, three different graft lengths (i.e., 30, 50, and 70 mm) were developed in the ACL reconstruction and analyzed using finite element method under two usual clinical test loads (i...

BACKGROUND: Injury to the anterolateral ligament (ALL) has been reported to contribute to high-grade anterolateral laxity after anterior cruciate ligament (ACL) injury. Failure to address ALL injury has been suggested as a cause of persistent rotational laxity after ACL reconstruction. Lateral meniscus posterior root (LMPR) tears have also been shown to cause increased internal rotation of the knee. QUESTIONS/PURPOSES: The purpose of this study was to determine the functional relationship between the ALL and LMPR in the control of internal rotation of the ACL-deficient knee...

A 29-year-old man with a previous football injury to his left knee presented with pain of the same knee. The patient twisted it as he was turning a corner quickly while going up the stairs, leading to internal rotation of his femur on his tibia with his knee in flexion. MR imaging revealed a bucket-handle tear of the medial meniscus, as well as a complete tear of the anterior cruciate ligament. However, image interpretation was complicated by the presence of a medial oblique meniscomeniscal ligament, a rare normal variant among intermeniscal ligaments of the knee...

BACKGROUND: Many patients who undergo anterior cruciate ligament (ACL) reconstructive surgery develop post-traumatic osteoarthritis (PTOA). ACL reconstructive surgery may not fully restore pre-injury joint biomechanics, thereby resulting in further joint damage and contributing to the development of PTOA. In an ovine model of idealized ACL reconstruction (ACL-R), it has been shown that signs of PTOA develop within surgical joints by 20 weeks post-surgery. The aim of the present study was to investigate whether altered kinematics contribute to early PTOA development within ACL-R joints of the ovine injury model by comparing the gait of these surgical animals to the gait of a stable normal control group, and an unstable injury group in which the ACL and medial collateral ligament (MCL) had been transected...

BACKGROUND: To determine if tibial tunnel reaming during anatomic single-bundle anterior cruciate ligament (ACL) reconstruction using hamstring autograft can result in anterolateral meniscal root injury, as diagnosed by magnetic resonance imaging (MRI). METHODS: A case series of 104 primary anatomic single-bundle ACL reconstructions using hamstring autograft was retrospectively reviewed. Pre- and post-operative (>1 year) MRIs were radiologically evaluated for each patient, with a lateral meniscus extrusion > 3 mm at the level of the medial collateral ligament midportion on a coronal MRI, to establish anterolateral meniscal root injury...

Bilateral cruciate ligament rupture is rare while simultaneous rupture in both anterior cruciate ligaments (ACL) is exceptional; that's why post-traumatic simultaneous bilateral cruciate ligament rupture has never been described in the literature making this case study based on patient's observation, follow-up and therapeutic discussion very interesting. The procedure was performed in two surgical steps spaced in time and results were very satisfactory for both us and patient.

Fascial Manipulation(®) (FM) is a manual therapy approach for the treatment of musculoskeletal pain. Anomalous fascial tension is common following surgery due to surgical scar, inadequate mobility and fear of movement. Fascial tension may result in pain and loss of mobility. This case report aims at investigating the effectiveness of FM(®) on pain and function in a patient following knee surgery. A 32 years old male patient, with persisting knee pain following anterior cruciate ligament reconstruction (hamstring graft) and meniscal repair, underwent the systematic FM(®) assessment process, the selected centers of coordination of myofascial units were treated...

In this paper, different nanocomposites made of a polymer blend (80% of PDLLA and 20% of PCL in w/w) and various amounts of a sol-gel derived bioactive glass nanoparticles (0, 1, 3 and 6wt%) were prepared using a solvent-evaporation technique. The morphology, mechanical properties and osteoblastic cell behaviors of the nanocomposites were evaluated. According to the early results, addition of bioactive glass nanoparticles to the polymer matrix reduced the tensile and flexural strength because of a non-uniform distribution of the nanoparticles...

BACKGROUND: Access to health care services is a critical component of health care reform and may differ among patients with different types of insurance. Hypothesis/Purpose: The purpose was to compare adolescents with private and public insurance undergoing surgery for anterior cruciate ligament (ACL) and/or meniscal tears. We hypothesized that patients with public insurance would have a delayed presentation from the time of injury and therefore would have a higher incidence of chondral injuries and irreparable meniscal tears and lower preoperative International Knee Documentation Committee (IKDC) scores than patients with private insurance...

One of the ligaments most often damaged during sports - the anterior cruciate ligament (ACL) - has poor healing capacity. Upon damage, reconstructive surgery is performed to restore the mechanical stability of the knee and to reduce the inflammatory milieu otherwise present in the joint. A return to normal activities, however, takes between 9 and 12 months. Thus, strategies capable of improving ACL graft healing are needed. Embryonic development of tendon and ligament (T/L) is regulated by a crosstalk between different cell types...

Intra-articular ligamentous injuries are typically unrepairable and have limited outcomes after graft reconstruction. A combination of porous polycaprolactone fumarate (PCLF) scaffolds with polyethylene terephthalate (PET) sutures was developed with the goal of regenerating intra-articular ligaments. Scaffolds were fabricated by injecting PCLF over 3D-printed molds containing two strands of PET suture down its central pore followed by crosslinking. Scaffolds were seeded with human mesenchymal stem cells (MSCs) from adipose tissue...
