To determine the warping angle of the costal cartilage in vivo. A nasal framework reconstruction with a rib graft was performed in a total of 130 patients. After the cartilage specimens were prepared, the remaining grafts were used for the experimental study. The angle of warping in all grafts was measured at 0, 30, and 60 minutes, after 24 hours and after one week. In this study, 8 subgroups of graft thicknesses from central and peripheral groups, which were determined according to the perichondral distance of the grafts, were evaluated, and the warping angles of a total of 48 osteochondral and chondral grafts were individually measured...

BACKGROUND AND OBJECTIVES: Surgical reconstruction following the removal of large malignant auricular lesions is challenging. While many options for defect closure have been described, in the elderly population usually affected flap surgery, long anesthesia times, patient compliance, and anticoagulant therapy pose additional risks. An alternative quick, simple, and effective method of defect closure is therefore highly desirable. The objective of the present study was to assess the aesthetic outcome, healing process, complications, and recurrence rates associated with unmeshed split-thickness skin grafts (STSGs) used for covering large auricular skin defects following cartilage-sparing skin cancer removal...

Juvenile allogenic chondrocyte implantation (JACI; DeNovo NT Natural Tissue Graft®; Zimmer, Warsaw, IN) with autologous bone marrow aspirate concentrate (BMAC) is a relatively new all-arthroscopic procedure for treating critical-size osteochondral lesions (OCLs) of the talus. Few studies have investigated the clinical and radiographic outcomes of this procedure. We collected the clinical and radiographic outcomes of patients who had undergone JACI-BMAC for talar OCLs to assess treatment efficacy and cartilage repair tissue quality using magnetic resonance imaging (MRI)...

In vitro production of tissues or tissue engineering is a promising approach to produce artificial tissues for regenerative medicine. There are at least three important components of tissue engineering, including stem cells, scaffolds and growth factors. This study aimed to produce cartilage tissues in vitro from culture and chondrogenic differentiation of rabbit bone marrow-derived mesenchymal stem cells (BMMSCs), induced by chondrogenesis medium, on biodegradable polycaprolactone (PCL) scaffolds. BMMSCs were isolated from rabbit bone marrow according to the standard protocol...

We designed tissue-reactive graft copolymers to protect the cartilage against enzymatic degradation and restore its lubrication properties during the early stages of osteoarthritis (OA). These feature a poly(glutamic acid) (PGA) backbone bearing hydroxyl benzaldehyde (HBA) functions and cyclic poly-2-methyl-2-oxazoline (PMOXA) side chains. PGA-PMOXA-HBA species chemisorb on the degraded tissue via Schiff-bases and expose the biopassive and lubricious PMOXA grafts at the interface. The smaller hydrodynamic radius of cyclic PMOXA side chains coupled to the intrinsic absence of chain ends generate denser and more lubricious films on cartilage when compared to those produced by copolymers bearing linear PMOXA...

Targeted and sustained delivery of drugs to diseased tissues/organs, where body fluid exchange and catabolic activity are substantial, is challenging due to the fast cleansing and degradation of the drugs by these harsh environmental factors. Herein, a multifunctional and bioadhesive polycaprolactone-β-cyclodextrin (PCL-CD) polymersome is developed for localized and sustained co-delivery of hydrophilic and hydrophobic drug molecules. This PCL-CD polymersome affords multivalent crosslinking action via surface CD-mediated host-guest interactions to generate a supramolecular hydrogel that exhibits evident shear thinning and efficient self-healing behavior...

Osteochondritis dissecans (OCD) of the humeral capitellum is a critical elbow injury in adolescent overhead throwing athletes. However, its etiology remains unknown. Medical examinations using ultrasonography found that the prevalence of capitellar OCD among adolescent baseball players was approximately from 1% to 3%. A plain anteroposterior radiograph with the elbow in 45° of flexion is essential for the diagnosis of an OCD lesion. The stability of OCD lesions is evaluated on plain radiographs, computed tomography, and magnetic resonance imaging (MRI)...

BACKGROUND: Articular cartilage health is an important issue following anterior cruciate ligament (ACL) injury and primary ACL reconstruction. Factors present at the time of primary ACL reconstruction may influence the subsequent progression of articular cartilage damage. HYPOTHESIS: Larger meniscus resection at primary ACL reconstruction, increased patient age, and increased body mass index (BMI) are associated with increased odds of worsened articular cartilage damage at the time of revision ACL reconstruction...

BACKGROUND: Autologous bone grafts (autografts) are used in surgery for defect filling and impaction grafting during hip socket and femur reconstruction. Because of their superior osteoinductive capacity, autografts are considered the "gold standard" for these treatments. However, because of a better cost-benefit ratio, allografts are also often used. In the case of limited donor availability for autologous or allogenic bone grafts, bone substitute materials (BSMs) are a reasonable alternative or supplement...

Injured articular cartilage has a limited innate regenerative capacity, due to the avascular nature and low cellularity of the tissue itself. Although several approaches have been proposed to repair the joint cartilage, none of them has proven to be effective. The absence of suitable therapeutic options has encouraged tissue-engineering approaches combining specific cell types and biomaterials. In the present work, we have evaluated the potential of a cell-free Collagen I-based scaffold to promote the augmentation of cartilage-like phenotype after subcutaneous implantation in the mouse...

BACKGROUND: Bone Morphogenetic Protein (BMP) graft showed promising outcome during early phases of its use. However unreported adverse events and off label use shattered its safe profile and raised concerns regarding its indication. In 2008, the Food and Drug Administration (FDA) prohibited its use in anterior cervical spine procedures due to possibility of edema, hematoma and need of intubation. At the molecular level, BMP act as multifactorial growth factors playing a role in cartilage, heart, and bone formation...

An 8 year-old female with esophageal atresia and a type IV laryngotracheoesophageal cleft underwent tracheostomy, gastric pull-up and fundoplication with G-tube insertion at birth. She remained nil per os due to aspiration. The trachealis was separated from the esophagus that was reapproximated and clavicular periosteum was placed. A long posterior costal cartilage graft that engaged behind the cricoid plate and tapered inferiorly was inserted. A second thin cartilage graft was sutured to it distally to extend the length of the repair...

Osteoarthritis is characterized by a chronic, progressive and irreversible degradation of the articular cartilage associated with joint inflammation and a reparative bone response. More than 100 million people are affected by this condition worldwide with significant health and welfare costs. Our available treatment options in osteoarthritis are extremely limited. Chondral or osteochondral grafts have shown some promising results but joint replacement surgery is by far the most common therapeutic approach. The difficulty lies on the limited regeneration capacity of the articular cartilage, poor blood supply and the paucity of resident progenitor stem cells...
