Objective: Videos uploaded to YouTube do not go through a review process, and therefore, videos related to patellofemoral instability may have little educational value. The purpose of this study was to assess the educational quality of YouTube videos regarding patellofemoral instability. Methods: A standard search was performed on the YouTube database using the following terms: “unstable kneecap,” “patellar instability,” “patellofemoral instability,” “kneecap dislocation,” and “patellar dislocation,” and the top 50 videos based on the “relevance” assignment of the YouTube algorithm were included for analysis. The properties, content, and source of each video were recorded. The educational quality of videos was analyzed according to scores obtained using DISCERN, the criteria of Journal of the American Medical Association , Global Quality Score, and Patellofemoral Instability Specific Score, and the quality of the videos was evaluated according to the groupings of these scoring systems. Results: A total of 250 videos were identified, of which 89 were included in the study for analysis. The mean video duration was 11.72 ± 22.03 minutes. The median number of views was 4516.5 (range, 3-6 044 971). The content of the videos was disease-specific in 60%, 20% were related to surgical technique or approach, and 14.1% were exercise videos. Most of the videos were uploaded by physicians (33.7%). The Global Quality Score and DISCERN scores were significantly correlated with video duration. The Patellofemoral Instability Specific Score was significantly correlated with video duration, number of views, view rate, likes, and Video Power Index. According to the DISCERN classification, 69.9% of the videos were very insufficient or insufficient. According to the Patellofemoral Instability Specific Score, 65.2% of videos were evaluated as very low or low. According to the Global Quality Score, 60.7% of videos were rated as poor quality. Conclusion: The quality of YouTube videos about Patellofemoral instability is insufficient. It was found that viewers tend to watch short and low-quality videos.

Almost a half of the hip fractures are extracapsular and are subclassified as intertrochanteric and subtrochanteric. [1] Fracture stability or fracture classification systems are used for the recommendation of treatment in intertrochanteric fractures. Such classifications are also used to recommend proper implant or surgical techniques. The ideal classification system allows interaction between physicians, guides the planning, predicts the treatment outcome, and is applicable for clinical practice and research. Examination of the fracture evaluation by the same physician and different physicians should yield the same result each time (intraobserver and interobserver reliability).Objectives: This study aims to evaluate the effect of surgical experience on reliability for Boyd-Griffin, Evans/Jensen, Evans, Orthopaedic Trauma Association (main and subgroups), and Tronzo classification systems.Patients and methods: Between January 2013 and December 2014, radiological images of a total of 60 patients (13 males, 47 females; mean age: 78.9±21.9 years; range, 61 to 96 years) with the diagnosis of intertrochanteric femur fracture were analyzed. Radiographs were evaluated and classified by five residents and five orthopedics and traumatology surgeons according to the Evans, Boyd-Griffin, Evans/Jensen, OTA, and Tronzo classification systems. Intraand interobserver reliability were calculated using the kappa statistics. Results:The worst intraobserver compatibility among the residents was the classification system with OTA subgroups (k=0.516), while the classification system with the best intraobserver fit was found to be OTA main groups (k=0.744). The worst agreement among surgeons was in the Evans classification system (k=0.456). However, the best intraobserver agreement was in the OTA main groups (k=0.741). The best interobserver agreement was observed regarding the OTA main groups (k=0.699). Conclusion:The classification that has the best harmony both among residents and surgeons, and between residents and surgeons is the OTA main group classification.

Background: Newborn clavicle fractures and brachial plexus injuries (BPIs) are rare but serious perinatal complications. Methods: The aim of this study was to examine the clinical relationship between the fracture morphology (spiral, oblique, transfer) of clavicle fractures that develop during delivery in newborns and BPI. We retrospectively reviewed all perinatal clavicle fractures diagnosed at our institution over 6 years. Results: The study included 55 newborn infants with perinatal clavicle fracture. Of these, 60% (n=33) were male. Right-side clavicle fractures were present in 56.4% (n=31) and shoulder dystocia was present in 58.2% (n=32) of the patients. Of the fracture localization of the patients, 85.5% (n=47) (Allman I) and 14.5% (n=8) (Allman II) were lateral. Allman type I fractures were not associated with increased BPI (P>0.05). It was observed that 40% (n=22) of the clavicle fractures were characterized by oblique morphology, 34.5% (n=19) of the fractures by spiral morphology, and 25.5% (n=14) of the fractures by transfer morphology. In all, 41.8% (n=23) of the sample also had BPI. Of the entire sample, 40% (n=22) most frequently showed oblique morphology fractures, whereas the patient group with BPI showed spiral morphology as the most common fracture, at a rate of 52.2% (n=10). After examining the relationship between fracture morphology and BPI, the study determined a statistically significant correlation between spiral and oblique morphology fractures and the development of BPI. Conclusions: To our knowledge, our study is the first to examine the relationship between newborn clavicle fracture morphology and BPI. We think that they should be evaluated for increased BPI risk in newborn patients that have clavicle fractures with spiral and oblique morphology.
