Synthetic biodegradable scaffolds such as polylactic acid coated polyglycolic acid (PLA-PGA) are especially suitable for engineering shaped cartilage such as auricle, but they induce a serious inflammatory reaction particularly in the immunologically aggressive subcutaneous site, leading to resorption of the engineered autologous cartilage. Our previous study in a rabbit model has demonstrated 2 weeks of in vitro precultivation could significantly alleviate the post-implantation inflammation induced by PLA-PGA engineered cartilaginous grafts, but reproduction of this result failed in a preclinical goat model...

Glenoid osteochondral defects can be a significant source of pain and disability in an active population. Many treatments are available, but most joint-preserving procedures are limited to debridement, abrasion chondroplasty, or marrow-stimulation techniques, all of which depend on healthy underlying bone and none of which address underlying bony pathology. Osteochondral autograft transfer has been a successful form of treatment for lesions in the knee, elbow, and ankle, especially when subchondral bone is involved...

INTRODUCTION: The mucosal cylindroma or adenoid cystic carcinoma is the second sinonasal non-epithelial malignant tumor frequency argument. Due to the achievement of the nasal mucosa and a late diagnosis reconstructions are often complex. We report the case of a mucous cylindroma recurrence of nasal septum requiring a wide and deep excision of the root of the nose with nasal reconstruction. CASE REPORT: A patient aged 66 years whose history resection two years ago with a mucous adenoid cystic carcinoma of the right side of the nasal septum, had a local recurrence T2NOM0 imposing a wide excision with amputation nasal septum own bones of nose, the anterior portion of the triangular cartilages...

The decision-making regarding and treatment of cartilage abnormalities requires a systematic approach. This article reviews the concepts and principles that guide the management of this complex problem. The precise incidence, demographics, and progression of cartilage lesions have not been clearly delineated. Pursuing a patient-centered approach that considers the available nonsurgical and surgical options remains the cornerstone of patient care. The importance of determining concomitant knee pathologies, the proper interpretation and implications of imaging findings, and an accurate determination of the intra-articular and subchondral findings represent the primary elements of the decision analysis...

BACKGROUND: Matrix-induced autologous chondrocyte implantation (MACI) has demonstrated encouraging outcomes in treating patients with knee cartilage defects. Postoperatively, the time required to attain full weightbearing (WB) remains conservative. HYPOTHESIS: We hypothesized that patients would have no significant clinical or radiological differences or graft complications after an 8-week or 6-week return to full WB after MACI. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1...

Tracheal replacement is performed after resection of a portion of the trachea that was impossible to reconnect via direct anastomosis. A tissue-engineered trachea is one of the available options that offer many advantages compared to other types of graft. Fabrication of a functional tissue-engineered trachea for grafting is very challenging, as it is a complex organ with important components, including cartilage, epithelium and vasculature. A number of studies have been reported on the preparation of a graftable trachea...

Chondrosarcoma is a malignant tumor that originates from cartilaginous cells and is characterized by cartilage formation. Only 5% to 10% of chondrosarcoma occurs in the head and neck area, and it is uncommon in the temporomandibular joint area. This report describes an unusual case with a rare, large chondrosarcoma in a 47-year-old woman who presented with painless swelling and trismus. Computed tomography showed a large mass approximately 8.5×6.0 cm in size arising adjacent to the lateral pterygoid plate and condyle...

BACKGROUND: The anterior cruciate ligament (ACL) takes part in the knees articular cinematic regulation, which is why its rupture should be repaired as soon as possible. The surgical treatment is targeted to substitute the ruptured ACL with a graft that recreates the anatomical and biomechanical functions. Nevertheless, there are different factors that may produce a second rupture. OBJECTIVE: To determine the risk factors and frequency of failure in the ACL reconstruction...

PURPOSE OF REVIEW: The caudal septum has important functional and aesthetic implications. Deviations in this area can result in important nasal obstruction due not only to blockage of the nasal passage but also to compromise of the internal nasal valve. Cosmetically, alterations in the caudal septum can result in a twisted nasal tip, loss of projection, rotation, and imbalance in the ala-columellar relationship. Contemporary surgical options will be discussed showing how to preserve, reshape, and reinforce the caudal septum to obtain a final looking nose that is not only functional but also aesthetically pleasing...

BACKGROUND: Secondary cleft lip nasal deformity is a complex deformity, and the variety of recommended techniques used to correct this deformity attests to it. Much of the nasal deformity can be attributed to an abnormal lower lateral cartilage. This study presents our experience with applying a lateral crural turnover flap with a sandwiched strut graft in adjunct with other procedures to correct unilateral secondary cleft lip nasal deformity. METHODS: A retrospective review was conducted of 20 cases of unilateral cleft lip patients undergoing secondary rhinoplasty with lateral crural turnover flap with strut graft...
