The repair of diseased or damaged cartilage remains one of the most challenging problems of musculoskeletal medicine. Tissue engineering advances in cartilage repair have utilized autologous and allogenic chondrocyte and cartilage grafts, biomaterial scaffolds, growth factors, stem cells, and genetic engineering. The mesenchymal stem cell has specifically attracted much attention because of its...
OBJECTIVES To evaluate magnetic resonance (MR) T2 mapping for characterization of cartilage repair tissue following matrix-associated autologous cartilage transplantation (MACT). MATERIALS AND METHODS Fifteen patients were evaluated following MACT using a 3T MR scanner. Patients were categorized into 2 postoperative intervals: I: 3-13 months, II: 19-42 months. Mean T2 relaxation times calcula...
After mandibulectomy in cancer surgery, reconstruction is often performed with a reconstruction plate covered with a soft-tissue free flap in patients in poor condition. However, the rate of complications for mandibular reconstruction is higher with a reconstruction plate than with vascularized bone grafts. We have developed a costal cartilage wrapping method to prevent exposure of the mandible...
Articular cartilage lesions are a particular challenge for regenerative medicine due to cartilage low self-ability repair in case of damage. Hence, a significant goal of musculoskeletal tissue engineering is the development of suitable structures in virtue of their matrix composition and biomechanical properties. The objective of our study was to design in vitro a supporting structure for autol...
Injuries to the articular cartilage of the knee are common. They alter the normal distribution of weightbearing forces and predispose patients to the development of degenerative joint disease. The management of focal chondral lesions continues to be problematic for the treating orthopaedic surgeon. Although many treatment options are currently available, none fulfill the criteria for an ideal r...
BACKGROUND Recognition of the symbiotic relationship between the meniscus and articular cartilage is critical to the success of meniscal allograft transplantation. Simultaneous combined meniscal allograft transplantation and cartilage restoration procedures have been proposed for patients with a symptomatic postmeniscectomy knee with a focal chondral defect that would have traditionally been co...
BACKGROUND Autologous chondrocyte implantation (ACI) is an established and well-accepted procedure for the treatment of localised full-thickness cartilage defects of the knee. METHODS The present review of the working group "Clinical Tissue Regeneration" of the German Society of Orthopaedics and Trauma (DGOU) describes the biology and function of healthy articular cartilage, the present state...
Postoperative rehabilitation programs following articular cartilage repair procedures will vary greatly among patients and need to be individualized based on the nature of the lesion, the unique characteristics of the patient, and the type and detail of each surgical procedure. These programs are based on knowledge of the basic science, anatomy, and biomechanics of articular cartilage as well a...
In recent years, increases in the number of articular cartilage injuries caused by environmental factors or pathological conditions have led to a notable rise in the incidence of premature osteoarthritis. Osteoarthritis, considered a disease of civilization, is the leading cause of disability. At present, standard methods for treating damaged articular cartilage, including autologous chondrocyt...
BACKGROUND The septal cartilage is the most useful donor site for autologous cartilage graft material in rhinoplasty. For successful nasal surgery, it is necessary to understand the developmental process of the nasal septum and to predict the amount of harvestable septal cartilage before surgery. METHODS One hundred twenty-three Korean patients who underwent three-dimensional (3D) facial bone...
