BACKGROUND: Videos uploaded to YouTube do not go through a review process. The educational aspect of these videos may be insufficient for patellofemoral pain syndrome (PFP). OBJECTIVE: To examine the reliability and educational quality of PFP videos on YouTube. METHODS: A standard search was performed in the YouTube database using the following terms: patellofemoral pain syndrome/anterior knee pain syndrome/anterior knee pain/patellofemoral pain. For each search term, the top 50 videos based on “relevance” assignment of YouTube’s algorithm were included in the examination. The remaining 96 videos after exclusion were included in the study. The educational quality and reliability of videos was analyzed using DISCERN, JAMA (The criteria of Journal of the American Medical Association), GQS (Global Quality Score) and PFPSS (Patellofemoral Pain Specific Score). RESULTS: According to PFPSS, 81.2% of the videos were evaluated as low and very low quality. According to the DISCERN classification, 74.9% of the videos were evaluated as poor and very poor. According to GQS, 59.4% of the videos had scores of 2 or less, which were considered poor quality. According to JAMA, 41.7% of the videos scored 2 and below. CONCLUSIONS: The information content of YouTube videos is inadequate. Video design should be created to be understandable by patients and to attract their attention while making these videos.

Objectives. Septic arthritis is a medical emergency with a mortality rate of approximately 10%, the knee being the most commonly affected joint (about 50% of cases). The systemic inflammatory response caused by septic arthritis may be affected by the severity of the infection or the success of surgical joint debridement. Materials and Methods. This article was a retrospective study on patients admitted to our hospital (between 2013 and 2020) with septic arthritis of the knee. Patients were diagnosed based on history, examination, blood test results, and knee aspirate fluid. The patient's response to antibiotic therapy was monitored in the outpatient setting using serological markers. Results. Of the 48 patients included in the study, 26 were male, and 22 were female. Based on the ROC analysis, the optimal cutoff value of preoperative NLR was 8.33. The AUC was 0.782 for postoperative NLR level (95% CI,0,626–0.938; p:0.009) and 0.922 for postoperative CAR level (95% CI,0.844–0.999; p <0.001). Postoperative NLR and CAR cutoff values are 15.4 and 115, respectively. Conclusions. Preoperative NLR elevation in septic arthritis may be associated with recurrent surgical debridement postoperatively. In addition, postoperative NLR and CAR values can predict debridement rates in patients after septic arthritis surgery.

Background: A displaced femoral neck fracture in patients over 70 years of age is a severe injury that affects the patient's quality of life. It is associated with increased morbidity and increased risk of mortality. Methods:The cases were divided into a monopolar group (n=167) and a bipolar group (n=175). Data on age, gender, ASA scores, length of stay, and other diseases were obtained from the patients' files. Dislocation, infection and periprosthetic fracture rates were examined by examining the outpatient records of the patients in the postoperative period. Results:The mean age of all patients included in the study was 79.7±8.16 years. 62.3% (n=213) of the patients were female and 37.7% (n=129) were male. There was no significant difference between the patients in the monopolar group and the bipolar group regarding complications (p=0.743). The 30-day mortality rates of the patients in the monopolar group were significantly higher than those in the bipolar group (p=0.041). Conclusions:The use of the bipolar head in the surgical treatment of geriatric displaced femoral neck fractures with hemiarthroplasty may not provide any advantage in terms of functionality or complications.
