Fractures of the patella in children and adolescents are rare injuries with particular characteristics. The aim of this study was an analysis of epidemiology, treatment strategy and outcome of this injury. Between 1992 and 2006 all fractures of the patella in patients with an age 5 16 years were included in a case control study. Besides outcome analysis using the modified HSS knee score, radiol...

background tissue engineering is used for the treatment of many diseases, and the ideal cell source for cartilage tissue engineering is chondrocytes. the main limitation of chondrocyte is the low number of cells in cartilage tissue engineering. this study investigated a suitable cell source with high proliferation rate to obtain a large number of chondrocytes. methods adult cartilage tissue sam...

conclusions both l-prp and l-prf could be used to effectively promote the healing of articular cartilage defects of the knee. results mean macroscopic scores of the treated defects were higher than the controls at all sampling times with significant differences (p < 0.05) observed between l-prf treated and control defects (10.13 vs. 8.37) and l-prp treated and control defects (10 vs. 8.5) at 4 ...

BACKGROUND Autologous costal cartilage grafts are common in rhinoplasty. To date, no formal systematic review of complications associated with autologous costal cartilage grafting in rhinoplasty exists. OBJECTIVES The authors review current literature to examine the rates of donor and recipient site complications associated with autologous costal cartilage in rhinoplasty. METHODS Databases ...

Femoral head fractures often result in damage to the articular cartilage. This article describes a patient who sustained a femoral head fracture-dislocation with significant damage to the articular cartilage of the weight-bearing portion of his femoral head (A). After anatomic reduction of the fracture, a 2×4-cm osteochondral articular defect existed at the weight-bearing portion of the femoral...

Patient was sedated with fentanyl and midazolam. Oral cavity and pharynx were locally anesthetized with lidocaine. The ET tube was withdrawn as tube cuff was placed between vocal cords using bronchoscope. Angiocath was inserted between the first and second tracheal cartilages and a guidewire was inserted through it.. The angiocath was then withdrawn and dilator was guided to trachea.. During in...

The dog was hit by a car and immediately after the accident no abnormalities were present. One month later there were changes in phonation and dyspnea. Considerations were laryngeal paralysis, laryngeal neoplasia, abscess, cyst, granuloma, or hematoma. Laryngeal collapse due to chondromalacia was considered less likely due to the breed. The laryngeal lumen was narrow with an irregular mucosal s...

Bone morphogenetic proteins (BMPs) are multi-functional growth factors belonging to the transforming growth factor ss superfamily. Family members are expressed during limb development, endochondral ossification, early fracture, and cartilage repair. The activity of BMPs was first identified in the 1960s but the proteins responsible for bone induction were unknown until the purification and clon...
