Nanothermometry-Enabled Intelligent Laser Tissue Soldering.

While often life-saving, surgical resectioning of diseased tissues puts patients at risk for post-operative complications. Sutures and staples are well-accepted and routinely used to reconnect tissues, however, their mechanical mismatch with biological soft tissue and invasiveness contribute to wound healing complications, infections, and post-operative fluid leakage. In principle, laser tissue soldering offers an attractive, minimally-invasive alternative for seamless soft tissue fusion.

Women and men in orthopaedics.

Purpose: To compare and discuss the gender disparities in the Orthopaedic specialty.

Methods: We reviewed the literature to find the rates of women applying for an orthopaedic residency, fellowship, and academic career program, to understand the causes of the disparities in women in orthopaedics, and how this relates to orthopaedic surgical practice.

Results: The idea that men and women are different and have different working styles and skills and the belief that males are more dominant and more status-worthy than females leads to gender barriers and stereotypes that restrict women from entering male-dominated specialties.

Minimally Invasive Versus Open Repair for Acute Achilles Tendon Rupture: Meta-Analysis Showing Reduced Complications, with Similar Outcomes, After Minimally Invasive Surgery.

Background: There is no consensus on the optimal technique for repairing an acute Achilles tendon rupture. The purpose of this meta-analysis was to compare the complications, subjective outcomes, and functional results between minimally invasive surgery and open repair of an Achilles tendon rupture.

Methods: A systematic literature search of MEDLINE/PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), EBSCOhost, and ClinicalTrials.

The Anterolateral Ligament Does Exist: An Anatomic Description.

The debate around the existence, anatomy, and role of the so-called anterolateral ligament of the knee represents one of the main sources of recent controversy among orthopedic surgeons. In the modern era of sports medicine, several content experts have contributed to the understanding of the anatomy of the anterolateral aspect of the knee. This article analyzes the historical, phylogenetic, anatomic, arthroscopic, and radiological evidence regarding the anterolateral ligament.

Mechanisms and situations of anterior cruciate ligament injuries in professional male soccer players: a YouTube-based video analysis.

Background: Soccer is considered the most popular sport in the world concerning both audience and athlete participation, and the incidence of ACL injury in this sport is high. The understanding of injury situations and mechanisms could be useful as substratum for preventive actions.

Purpose: To conduct a video analysis evaluating the situations and mechanisms of ACL injury in a homogeneous population of professional male soccer players, through a search entirely performed on the YouTube.

Tendon Extracellular Matrix Alterations in Ullrich Congenital Muscular Dystrophy.

Collagen VI (COLVI) is a non-fibrillar collagen expressed in skeletal muscle and most connective tissues. Mutations in COLVI genes cause two major clinical forms, Bethlem myopathy and Ullrich congenital muscular dystrophy (UCMD). In addition to congenital muscle weakness, patients affected by COLVI myopathies show axial and proximal joint contractures and distal joint hypermobility, which suggest the involvement of the tendon function.

Variants in KIF1A gene in dominant and sporadic forms of hereditary spastic paraparesis.

KIF1A gene encodes the kinesin 1a protein, an axonal motor protein working in cargo transport along neurites. Variants in KIF1A were identified in different forms of neurodegenerative diseases with dominant and recessive inheritance. Homozygous recessive mutations were found in the hereditary sensory and autonomic neuropathy type 2, HSAN2 and in a recessive subtype of hereditary spastic paraparesis, SPG30.

Knee arthrodesis with a press-fit modular intramedullary nail without bone-on-bone fusion after an infected revision TKA.

Introduction: Knee arthrodesis can be an effective treatment after an infected revision Total Knee Arthroplasty (TKA). The main hypothesis of this study is that a two-stage arthrodesis of the knee using a press-fit, modular intramedullary nail and antibiotic loaded cement, to fill the residual gap between the bone surfaces, prevents an excessive limb shortening, providing satisfactory clinical and functional results even without direct bone-on-bone fusion.

Material And Methods: The study included 22 patients who underwent knee arthrodesis between 2004 and 2009 because of recurrent infection following revision-TKA (R-TKA).

Meniscal allograft transplantation without bone plugs: a 3-year minimum follow-up study.

Background: Meniscal allograft transplantation is a viable option for subtotally meniscectomized and totally meniscectomized symptomatic patients and potentially results in pain relief and increased function.

Hypothesis: The use of a single tibial tunnel arthroscopic technique without bone plugs will reduce symptoms (pain) and improve knee function at a minimum 3-year follow-up.

Study Design: Case series; Level of evidence, 4.

Osteochondral tissue engineering approaches for articular cartilage and subchondral bone regeneration.

Purpose: Osteochondral defects (i.e., defects which affect both the articular cartilage and underlying subchondral bone) are often associated with mechanical instability of the joint and therefore with the risk of inducing osteoarthritic degenerative changes.

Arthroscopic intra- and extra-articular anterior cruciate ligament reconstruction with gracilis and semitendinosus tendons: a review.

The purposes of this paper are to summarize the concepts relating to the use of a combined intra-articular and extra-articular reconstructive procedure in the arthroscopic treatment of a torn ACL and to review several operative techniques utilizing gracilis and semitendinosus tendons that are currently in use to treat this instability. The highly satisfactory results obtained over the time show that a combination of intra- and extra-articular procedures for ACL reconstruction is a valid surgical option.

Platelet-rich plasma: new clinical application: a pilot study for treatment of jumper's knee.

This study describes a simple, low-cost, minimally invasive way to apply PRP growth factors to chronic patellar tendinosis; 20 male athletes with a mean history of 20.7 months of pain received treatment, and outcomes were prospectively evaluated at 6 months follow-up. No severe adverse events were observed, and statistically significant improvements in all scores were recorded.

Histological and ultrastructural evaluation of Leeds-Keio ligament 20 years after implant: a case report.

We were capable of undertaking a histological and ultrastructural evaluation of an intact Leeds-Keio ligament implanted 20 years ago to assess the neoligamentization process inside this artificial ligament. The histological evaluation disclosed a collagen fibrils orientation very close to the structure of a normal anterior cruciate ligament (ACL) where the collagen fibres are multidirectional [Strocchi et al. in J Anat 180(3):515-519, 1992].
