BACKGROUND: With the continuous advances in the therapy of joint cartilage injury, some of those classification systems are also being used for evaluating the quality of regenerating cartilage. Histo lo gi cal assessment of joint cartilage is a very important component in the staging of osteoarthritis and tracing therapeutic outcomes. We performed a histological assessment of regenerating growth plate in a group of New Zealand white rabbits as a component of autologous chondrocyte therapy for growth plate damage...

PROPOSE: Since 2006, we have explored the option of using septal cartilage as an alar rim graft on the cleft side during primary rhinoplasty to improve nasal symmetry. The aim of this study was to compare the nasal shape with or without rim graft. METHODS: A total of 98 patients with unilateral complete cleft lip and palate were included; 39 patients had septal cartilage as the rim graft, 59 patients did not. Measurements of the nostril height, nostril width, 1/4 medial part of nostril height, nostril area, nasal dome height and nostril axis were made on the cleft and non-cleft side...

BACKGROUND: Clinical outcomes after meniscal allograft transplantation (MAT) in arthritic knees are unclear, and objective estimates of graft survival according to the articular cartilage status have not been performed. HYPOTHESIS: MAT should provide clinical benefits in knees with high-grade cartilage damage, but their graft survivorship should be inferior to that in knees with low-grade chondral degeneration after MAT. STUDY DESIGN: Cohort study; Level of evidence, 3...

INTRODUCTION: There is no evidence that anatomically correct anterior cruciate ligament reconstruction (ACLR) offers lower rate of degenerative changes development or that it would lead to a better outcome. The significance and understanding of the abnormal anterior tibial translation (ATT) in ACLR patients is yet to be established. METHODS: Sixty subjects (40 patients at 5.9 years after ACLR, 20 healthy controls) underwent 3 T MRI. Quantitative cartilage T2 mapping and morphological whole organ magnetic resonance imaging score (WORMS) evaluation was performed...

BACKGROUND: Septal extension grafts are an effective means of extending nasal length in patients with a short nose. However, such grafts can be challenging in patients who only have small quantities of weak septal cartilage, such as some East Asian patients. We developed a rhinoplasty technique using ethmoid bone to create a cartilage-bone complex to overcome this issue, allowing adequate nasal lengthening. METHODS: Sixty-four women with short noses and inadequate septal cartilage determined by preoperative computed tomography underwent septal extension grafting with a cartilage-bone complex between January 2009 and December 2014...

BACKGROUND: The use of autologous chondrocyte implantation (ACI) remains limited, even though multiple studies have demonstrated success rates exceeding 75%. The procedure is perceived as invasive and technically challenging, presenting barriers to more widespread adoption. Purpose/Hypothesis: The objective of this study was to investigate whether outcomes and the failure rate of a simplified ACI technique (cs-ACI) were comparable with those of the more complicated traditional technique of a chondrocyte suspension injected under a collagen membrane (cACI)...

BACKGROUND: Results of anterior cruciate ligament (ACL) reconstruction are traditionally excellent in younger and nonarthritic patients. During the past few decades, people older than 60 years have become more active than ever, with more demanding physical lifestyles. An increase also has been noted in active patients with diagnosed ACL injuries. More patients are requesting treatment for ACL deficiency in hopes of returning to preinjury levels of activity. PURPOSE: The aims of this study were to evaluate the results of ACL reconstruction in patients older than 60 years in terms of functional recovery, return to sports, and postoperative incidence of osteoarthritis and to compare their results with published results of different age groups...

INTRODUCTION: Chondral and osteochondral lesions represent a debilitating disease. Untreated lesions remain a risk factor for more extensive joint damage. The objective of this clinical study is to evaluate safety and early results of an aragonite-based scaffold used for osteochondral unit repair, by analysing both clinical outcome and MRI results, as well as the benefits of the procedure optimization through novel tapered shaped implants. METHODS: A crystalline aragonite bi-phasic scaffold was implanted in patients affected by focal chondral-osteochondral knee lesions of the condyle and trochlea...

Nipple projection of a modified C-V flap with or without costal cartilage was compared on abdominal, breast, and dorsal skin. A total of 81 patients and 85 sites were studied. The nipple was reconstructed secondarily using a modified C-V flap. Patients were classified by breast mound skin into five groups: dorsal skin without cartilage (group A, n = 18); abdominal skin without cartilage (group B, n = 6); abdominal skin with cartilage (group C, n = 26); breast skin without cartilage (group D, n = 20); and breast skin with cartilage (group E, n = 15)...

Yong Ju Jang, Do-Youn Kim
Revision rhinoplasty in Asian patients is associated with problems related to the use of grafts or implant materials. Moreover, the septal cartilage of Asian individuals is generally weak and small, which makes it particularly vulnerable to injury or secondary deformity during primary surgery. Hence, there is an increased demand for major reconstruction of the septal cartilage framework during revision surgery in Asian patients. In revision rhinoplasty of the nose in Asian patients, appropriate management of the graft or implant is vital...

BACKGROUND: Over the past few years, conchal cartilage has been most often used in rhinoplasty. The donor site complications following conchal cartilage graft harvesting are scar formation, hematoma formation, and delayed wound healing, although hematoma is one of the most important and common complications. A complete conchal defect as a complication of auricular cartilage graft harvesting has not been previously reported in the literature. The authors report an unusual case of an iatrogenic conchal defect resulting from conchal cartilage graft harvesting that was treated using a posterior auricular island flap...

BACKGROUND: Diced cartilage wrapped in fascia or modeled with tissue sealant has successfully been used as dorsal onlay grafts in rhinoplasty. The use of autologous material introduces the risk of donor site morbidity, and sometimes availability is limited. METHODS: We present a series of nine cases that were performed using diced irradiated homologous rib cartilage as an onlay graft. RESULTS: Good functional and cosmetic outcomes were achieved in all nine patients, and no significant resorption was seen after a mean follow-up of 20 months...

Tae-Hoon Kim, Ie-Hyon Park, Sa-Hyeok Hong, Seok-Chan Eun
BACKGROUND: Posttraumatic enophthalmos is a relatively common problem following orbitozygomatic fractures. However, inadequate long-term results are frequently observed due to the difficulty of performing intraoperative fine adjustments to soft-tissue volume and orbital size and gradual absorption of some grafted materials. Here, the authors describe an efficient method of enophthalmos correction using sliced costochondral bone and cartilage combination grafts. METHODS: From 2005 to 2011, the authors corrected enophthalmos in 12 patients using sliced costochondral grafts...

OBJECTIVES: Pediatric rhinoplasty has traditionally raised numerous concerns, including its impact on growth as well as the psychological sequelae of undergoing a potentially appearance-altering procedure. Our objective was to critically evaluate available individual patient data relevant to pediatric rhinoplasty, and further discuss perioperative considerations. METHODS: A systematic review was conducted using PubMed/MEDLINE databases. Data extracted and analyzed from included studies included patient demographics, surgical indications, operative approaches, outcomes, complications, revision rates, and other clinical considerations...

BACKGROUND: Anatomic surgical reconstruction of the medial patellofemoral ligament (MPFL) has been popularized for the treatment of recurrent patellar instability in the skeletally immature population. Previous anatomic studies have found that the femoral attachment point of the MPFL is very close to the distal femoral physis. PURPOSE: To establish the safe angles for drilling the distal femoral epiphysis for MPFL graft placement. STUDY DESIGN: Descriptive laboratory study...

C Niek van Dijk
In general, osteochondral allograft should include minimal "osteo" or bone. In cases that require a bulk allograft, even after creeping substitution and healing, most of the graft remains dead bone. Bulk dead bone is a particular problem in the talus, should a patient need revision to a prosthesis or arthrodesis. As an alternative, drilling, bone grafting, and fixation of existing cartilage, when possible, is preferred.

Reconstructing congenital auricular defects due to hemifacial microsomia (HFM) is often required to deal with low hairline and defects of the temporal fascia/muscular systems. In this report, we present two cases of HFM patients (16-year-old and 20-year-old) with positional anomaly of the remnant lobule and 95% low hairline, who were treated with serratus anterior fascial flap (SFF) at the second stage of auricular construction. At the first stage, 3D costal cartilage framework was placed following the removal of hair-bearing skin, and was resurfaced with the pericranial flap...
