BACKGROUND: Double-bundle anterior cruciate ligament (ACL) reconstruction has demonstrated improved biomechanical properties and moderately better objective outcomes compared with single-bundle reconstructions. This could make an impact on the rerupture rate and reduce the risk of revisions in patients undergoing double-bundle ACL reconstruction compared with patients reconstructed with a traditional single-bundle technique. The National Knee Ligament Registers in Scandinavia provide information that can be used to evaluate the revision outcome after ACL reconstructions...

Butterfly graft inlay tympanoplasty is a well-established technique for the repair of small- and medium-sized perforations. There are some difficulties with application of conventional butterfly technique and it affects our success rate of graft healing. With some modifications of graft preparation we can make better success rates. The aim of this study was to present the new renovation of conventional method, describe about what kind of changes we made and its technical facilities about the procedure. The study design is a prospective case series...

Articulating joints owe their function to the specialized architecture and the complex interplay between multiple tissues including cartilage, bone and synovium. Especially the cartilage component has limited self-healing capacity and damage often leads to the onset of osteoarthritis, eventually resulting in failure of the joint as an organ. Although in its infancy, biofabrication has emerged as a promising technology to reproduce the intricate organization of the joint, thus enabling the introduction of novel surgical treatments, regenerative therapies, and new sets of tools to enhance our understanding of joint physiology and pathology...

We report on two unusual cases of Cosman (question mark) ear; both required modifications of the standard techniques for surgical correction. The first patient presented with a unilateral question mark ear and concurrent ear prominence and bulging of the cartilage of the anti-helix. Simultaneous correction was done using a combination of cartilage suturing/scoring (for the prominence and the cartilage bulge) as well as Al-Qattan's "v-y skin flap-cartilage graft-z-plasty" technique (for the correction of the ear cleft deformity)...

BACKGROUND: Temporomandibular joint (TMJ) ankylosis is a situation in which the mandibular condyle is fused to the glenoid fossa by bone or fibrous tissue. The management of TMJ ankylosis has a complicated chore, and it is challenging for the maxillofacial surgeon because of technical hitches and high rate of reankylosis. Costochondral graft (CCG) is a common treatment modality for TMJ ankylosis. One of disadvantages of CCG is unpredictability of growth pattern and risk of overgrowth...

Cartilage defects represent a serious problem due to the poor regenerative properties of this tissue. Regarding the nose, nasal valve collapse is associated with nasal blockage and persistent airway obstruction associated with a significant drop in the quality of life for patients. In addition to surgical techniques, several cell-based tissue-engineering strategies are studied to improve cartilage support in the nasal wall, that is, to ameliorate wall insufficiency. Nevertheless, there are no congruent data available on the benefit for patients during the follow-up time...

Background Full-thickness cartilage lesions of the patella represent a common source of pain and dysfunction. Previously reported surgical treatment options include marrow stimulation, cell-based treatments, and osteochondral transfer. Minced juvenile allograft cartilage is a novel treatment option that allows for a single stage approach for these lesions. Hypothesis Particulated juvenile allograft cartilage (PJAC) for the treatment of chondral defects of the patella would offer acceptable lesion fill rates, mature over time, and not be associated with any negative biologic effects on the surrounding tissue...

PURPOSE: Autologous subchondral bone grafting in combination with autologous chondrocyte implantation (ACI) (sandwich procedure) is a well-accepted procedure for the treatment of osteochondral lesions of the knee. This requires a different surgical technique and preoperative planning compared to ACI alone. In addition, pain from bone marrow donor site locations can be expected and should be part of patient consent and expectations. This study evaluates whether the MRI made as part of the standard preoperative cartilage patient work up has the diagnostic accuracy to predict the need for a sandwich procedure...

Cartilage injury of the knee that is associated with significant subchondral bone loss can result in great morbidity, and treatment options that provide durable repair are limited. Osteochondral autograft and allograft reconstruction of these lesions has been used extensively; however, these techniques often require a more invasive surgical exposure, and restoring the natural articular surface radius of curvature can be challenging, particularly in larger lesions. Cell-based repair of these lesions, using autologous chondrocytes in conjunction with bone grafting, has been used with success, although this procedure requires the patient to undergo 2 operations, and access is often restricted due to the high associated costs...

BACKGROUND: The aim of tracheal reconstruction is to provide an airtight and noncollapsible airway covered with a suitable epithelial lining. To date, no ideal treatment is available for large tracheal defects. METHODS: We report 4 patients who underwent one-stage reconstruction for a cricotracheal stenosis with a free temporoparietal fascia flap and costal cartilage grafts. RESULTS: Closure of tracheostoma was achieved for all patients. The main advantage of this flap compared with the free radial forearm flap is that it supplies a more suitable lining allowing the reepithelialization process with respiratory epithelium...

Orthobiologics are biological substances that allow injured muscles, tendons, ligaments, and bone to heal more quickly. They are found naturally in the body; at higher concentrations they can aid in the healing process. These substances include autograft bone, allograft bone, demineralized bone matrix, bone morphogenic proteins, growth factors, stem cells, plasma-rich protein, and ceramic grafts. Their use in sports medicine has exploded in efforts to increase graft incorporation, stimulate healing, and get athletes back to sport with problems including anterior cruciate ligament ruptures, tendon ruptures, cartilage injuries, and fractures...
