Review
PURPOSE
To perform a systematic review of the use of autologous chondrocyte implantation (ACI) in the adolescent knee.
SPECIFIC AIMS
(1) quantify clinical outcomes of ACI in adolescent knees, (2) identify lesion and patient factors that correlate with clinical outcome, and (3) determine the incidence of complications of ACI in adolescents.
METHODS
PubMed, MEDLINE, SCOPUS, CINAHL, and Cochrane Collaboration Library databases were searched systematically. Outcome scores recorded included the International Knee Documentation Committee score, the International Cartilage Repair Society score, the Knee Injury and Osteoarthritis Outcome Score, the visual analog scale, the Bentley Functional Rating Score, the Modified Cincinnati Rating System, Tegner activity Lysholm scores, and return athletics. Outcome scores were compared among studies based on proportion of adolescents achieving specific outcome quartiles at a minimum 1-year follow-up. Methodologic quality of studies was evaluated by Coleman Methodology Scores (CMSs).
RESULTS
Five studies reported on 115 subjects who underwent ACI with periosteal cover (ACI-P; 95, 83%), ACI with type I/type III collagen cover (ACI-C; 6, 5%), or matrix-induced ACI (MACI; 14, 12%). Mean patient age was 16.2 years (range, 11 to 21 years). All studies were case series. Follow-up ranged from 12 to 74 months (mean, 52.3 months). Mean defect size was 5.3 cm(2) (range, 0.96 to 14 cm(2)). All studies reported improvement in clinical outcomes scores. Graft hypertrophy was the most common complication (7.0%). The mean preoperative clinical outcome percentage (based on percentage of outcome scale used) was 37% (standard deviation [SD], 18.9%) and the mean postoperative clinical outcome percentage was 72.7% (SD, 16.9%). The overall percentage increase in clinical outcome scores was 35.7% (SD, 14.2%). Mean CMS was 47.8 (SD, 8.3).
CONCLUSIONS
Cartilage repair in adolescent knees using ACI provides success across different clinical outcomes measures. The only patient- or lesion-specific factor that influenced clinical outcome was the shorter duration of preoperative symptoms.

Review
BACKGROUND
Today, minimally invasive procedures are becoming more popular because of the fast recovery. Rhinoplasty is a common facial plastic surgery procedure that can be associated with significant postoperative morbidities, especially periorbital edema and ecchymosis. The aim of this review is to summarize the results of published literature that studied interventions that decrease postoperative edema and ecchymosis after rhinoplasty, and provide evidence-based strategies for surgeons to incorporate into practice.
METHODS
A systematic review of the PubMed, Scopus, and EMBASE databases was performed to investigate interventions studied to decrease postoperative edema and ecchymosis after rhinoplasty. After inclusion and exclusion criteria were applied, articles were grouped into one of the following categories: corticosteroids, other medications and herbal supplements, interventions to decrease intraoperative bleeding, other postoperative interventions, and surgical techniques.
RESULTS
A total of 50 articles were included for review. Fourteen articles studied corticosteroids exclusively, whereas another 10 articles reviewed other medications and herbal supplements. Nine articles evaluated methods to decrease intraoperative bleeding during rhinoplasty, and four articles studied postoperative interventions to decrease edema and ecchymosis. Thirteen articles studied various surgical techniques to decrease postoperative morbidities.
CONCLUSIONS
There was a consensus within the literature that steroids, intraoperative hypotension, intraoperative cooling, and head elevation postoperatively decrease postoperative edema and ecchymosis, whereas nasal packing and periosteal elevation before osteotomy increased these postoperative morbidities. Studies of herbal supplements may be incorporated into practice with minimal risk to the patient. More studies must be performed before recommending an external or internal approach to lateral osteotomy.

Review
SUMMARY
A systematic review of eight ulnar fractures in seven patients with bisphosphonate therapy was performed to describe the characteristics and predisposing factors. The proximal ulna is likely to be fractured, especially in the dominant limb of elderly female patients using walking aids after 7 to 15 years of bisphosphonate use.
INTRODUCTION
Long-term bisphosphonate use has been suggested to result in decreased bone remodelling and increased risk of atypical fractures. While the relationship between bisphosphonate use and atypical femoral fractures has been extensively studied, there is relative rarity and unawareness of these fractures in the forearm. We conducted a systematic review of existing case reports to better describe the characteristics and predisposing factors for fractures occurring in patients with bisphosphonate therapy.
METHODS
The systematic review was conducted according to PRISMA guidelines. All studies with ulnar fractures in individuals with history of bisphosphonate use were included, with data extracted and analysed in totality.
RESULTS
Seven patients with eight fractures are included. Predisposing factors include elderly females requiring walking aids. There is a propensity for the proximal ulna to be fractured, especially in the dominant limb used for ambulation or transfer. All patients were on bisphosphonate for 7 to 15 years. All fractures were atraumatic, non-comminuted, transverse in configuration, had localised periosteal or endosteal thickening at the fracture site and generalised cortical thickening of the diaphysis.
CONCLUSION
Ulnar fractures in patients with bisphosphonate therapy demonstrate features similar to those described for atypical femoral fractures, suggesting that these fractures could also possibly be due to bisphosphonate use. However, the ulna appears to be able to tolerate longer periods of alendronate use prior to fracture development. The mechanism and characteristics of these fractures additionally suggest the presence of repetitive stress that accumulates over time due to suppressed bone remodelling in patients on bisphosphonates, eventually resulting in these fractures.
