Cartilage injuries may be detected using contrast-enhanced computed tomography (CECT) by observing variations in distribution of anionic contrast agent within cartilage. Currently, clinical CECT enables detection of injuries and related post-traumatic degeneration based on two subsequent CT scans. The first scan allows segmentation of articular surfaces and lesions while the latter scan allows evaluation of tissue properties. Segmentation of articular surfaces from the latter scan is difficult since the contrast agent diffusion diminishes the image contrast at surfaces...

BACKGROUND: A timely return to competitive sport is a primary goal of anterior cruciate ligament reconstruction (ACLR). It is not known if an accelerated return-to-sport increases the risk of early-onset knee osteoarthritis (KOA). OBJECTIVE: To determine whether an accelerated return-to-sport post-ACLR (i.e., <10 months) is associated with increased odds of early KOA features on MRI 1-year post-surgery, and to evaluate the relationship between an accelerated return-to-sport and early KOA features stratified by type of ACL injury (isolated or concurrent chondral/meniscal injury) and lower-limb function (good or poor)...

Background Symptomatic pre-arthritic deformities such as femoroacetabular impingement (FAI) or hip dysplasia often lead to localised cartilage defects and subsequently to osteoarthritis. The present review of the working group "Clinical Tissue Regeneration" of the German Society of Orthopaedics and Trauma (DGOU) and the hip committee of the AGA (German speaking Society for Arthroscopy and Joint Surgery) provides an overview of current knowledge of the diagnosis and surgical treatment of cartilage defects, in order to infer appropriate therapy recommendations for the hip...

RATIONALE: Chondrosarcoma, characterized by the production of cartilage matrix, is a common bone tumor, accounting for 20% to 27% of all malignant bone tumors. It often occurs in the cartilage of the pelvis, femur, tibia, and humerus. However, chondrosarcoma of the patella is extremely rare. PATIENT CONCERNS: The present study describes a case of chondrosarcoma affecting the right patella in a 68-year-old woman. The chief complaints were painful swelling and limitation of motion of the right knee for about half a year...

Many efforts are being directed worldwide to the treatment of OA-focal lesions. The majority of those efforts comprise either the refinement of surgical techniques or combinations of biomaterials with various autologous cells. Herein, we tested electrospun polycaprolactone (PCL) nanofibrous meshes for cartilage tissue engineering. For that, articular chondrocytes (hACs) isolated from human osteoarthritic joints and Wharton's Jelly Stem Cells (hWJSCs) were cultured on electrospun nanofiber meshes, without adding external growth factors...

BACKGROUND: Congenital erythropoietic porphyria is a rare autosomal recessive disorder that affects heme-porphyrin synthesis. This disorder is due to the genetic defect of uroporphyrinogen III cosynthase. This defect results in the accumulation of high amounts of uroporphyrin I in all tissues, leading to clinical manifestations ranging from mild to severe chronic damage of the skin, cartilage and bone. Hypertrichosis, erythrodontia and reddish-colored urine are often present, as well as hemolytic anemia accompanied by hepatosplenomegaly...

Laryngeal granulomas are benign lesions located in the posterior third of the glottis, mainly at the level of the vocal apophysis of the arytenoid cartilage. They are typically associated with three etiological factors: endotracheal intubation, inappropriate voice use and/or gastroesophageal reflux. The formation of a post-intubation laryngeal granuloma is a late complication related to intubation injury. It is uncommon in the child, especially if the period of intubation is short. It is usually unilateral and produces dysphonia, pharyngeal foreign body sensation and cough...

BACKGROUND: Meniscal lesions are among the most important musculoskeletal disorders and are the most common indication for knee joint arthroplasty. However, the structural integrity and function is rarely retained, and a loss of tissue results. Thus, there is a huge demand for meniscal replacement options. CURRENT PROCEDURES: Autografts were used in the past but did not fulfill expectations. Meniscus allografts have been developed to be a viable treatment option...

INTRODUCTION: Chondroblastoma (also known as Codman tumor) is a rare intermediate grade cartilaginous neoplasm, representing less than 1% of all primary bone tumors; it characteristically arises in the epiphysis or apophysis of a long bone in young patients, predominantly males. The most frequent location of chondroblastoma is the humerus (70% incidence rate) and more rarely it is located in the pelvis. When it affects the hip, the triradiate cartilage is the most common site. MATERIALS AND METHODS: An unusual case of Chondroblastoma located in the triradiate cartilage is reported...

Conventional arthroscopic evaluation of articular cartilage is subjective and poorly reproducible. Therefore, implementation of quantitative diagnostic techniques, such as near infrared spectroscopy (NIRS) and optical coherence tomography (OCT), is essential. Locations (n = 44) with various cartilage conditions were selected from mature equine fetlock joints (n = 5). These locations and their surroundings were measured with NIRS and OCT (n = 530). As a reference, cartilage proteoglycan (PG) and collagen contents, and collagen network organization were determined using quantitative microscopy...

BACKGROUND: Abnormal joint motion has been linked to joint arthrosis after anterior cruciate ligament (ACL) reconstruction. However, the relationships between the graft properties (ie, structural and anatomic) and extent of posttraumatic osteoarthritis are not well defined. HYPOTHESES: (1) The structural (tensile) and anatomic (area and alignment) properties of the reconstructed graft or repaired ACL correlate with the total cartilage lesion area 1 year after ACL surgery, and (2) side-to-side differences in anterior-posterior (AP) knee laxity correlate with the total cartilage lesion area 1 year postoperatively...

REVIEW
P Beaufils, N Pujol
Meniscectomy remains one of the most frequent orthopedic procedures, despite meniscal sparing having been advocated for several decades now. Incidence is excessive in the light of scientifically robust studies demonstrating the interest of meniscal repair or of non-operative treatment for traumatic tear and of non-operative treatment for degenerative meniscal lesions. It is high time that the paradigm shifted, in favor of meniscal preservation. In traumatic tear, and most particularly longitudinal vertical tear in vascularized zones, repair shows a high success rates in terms of recovery time, functional outcome and cartilage protection...

BACKGROUND: Chondrolabral damage is commonly observed in patients with cam-type femoroacetabular impingement (FAI). Chondral flap reattachment has recently been proposed as a possible preservation technique. PURPOSE/HYPOTHESIS: The purpose of this study was to determine the viability and tissue quality of chondral flaps from patients with FAI at the time of arthroscopy. It was hypothesized that chondral flaps from patients with cam lesions of the hip would exhibit less viability and greater tissue degeneration than would those of a matched control group...

BACKGROUND: Extraskeletal mesenchymal chondrosarcoma (ESMCS) is an unusual pathologic variant of chondrosarcoma. There are no specific clinicoradiographic parameters to distinguish it from other intracranial pathologies. The diagnosis can be established only on the basis of histopathology, which may pose significant challenges in certain unusual locations. PURPOSE: In this case, we discuss the pitfalls in diagnosis, management, and major characteristics of ESMCS with a review of current literature...

REVIEW
Alan Ng, Andrew Bernhard, Kaitlyn Bernhard
Repair of osteochondral lesions of the talus can be difficult. Smaller lesions respond well to simple arthroscopy and microfracture, whereas larger cystic lesions may require allograft talus replacement or ankle fusions. The lesions in between are more difficult to treat. Autologous chondrocyte implantation and matrix-associated autologous chondrocyte implantation have shown promising results. Future research may include new techniques, pharmacologic intervention, and cell-based therapies, and may be better served with prospective observational studies instead of costly randomized controlled studies...

Large, symptomatic, focal chondral, and osteochondral lesions of the ankle are treated with osteochondral autograft/allograft transplantation (OAT) procedure, a reconstructive bone grafting technique that uses one or more cylindrical osteochondral grafts from an area of low impact or allograft source and transplants them into the prepared defect site on the talus. This technique allows defects to be filled with mature, hyaline articular cartilage. Acute or chronic chondral or osteochondral lesions can be debilitating; provided here is a review of osteochondral autograft or allograft transplantation...
