RESUMO
BACKGROUND: In professional athletes, Achilles tendon ruptures are devastating injuries, often resulting in season loss or decreased return to sports level. We aimed to perform a comprehensive video analysis to describe the mechanisms of Achilles tendon rupture as well as body posture in professional athletes. We hypothesized that Achilles tendon ruptures in professional athletes develop with a specific injury mechanism and that body posture at the time of injury varies by sport. METHODS: Of 114 identified Achilles tendon ruptures that occurred in professional athletes between 1970 and 2020, 42 with adequate video data were analyzed for injury mechanism, body posture, and player and sport characteristics by three independent reviewers. RESULTS: Mean ± SD age of the 42 athletes (41 men and 1 woman) was 28.4 ± 4.26 years. Eighteen athletes played basketball (42.9%), 14 football (33.3%), five soccer (11.9%), three baseball (7.1%), and two rugby (4.8%). Thirty-five patients (83.3%) had noncontact injuries. The most frequent months of injury were January (16.7%) and October (14.3%). During Achilles tendon rupture, the ankle was in dorsiflexion, the body was bent forward, the knee and hip were in extension, and the foot was in a neutral position. Most injuries occurred during take-off/acceleration (40.5%) or stop and turn (38.5%) maneuvers. CONCLUSIONS: In professional athletes, the Achilles tendon most often ruptures during take-off/acceleration. The most common position during rupture is the trunk in flexion, the knee and hip in extension, and the ankle in dorsiflexion. This information can guide professional athletes in terms of physical therapy techniques, including neuromuscular training, proprioception, and balance training specific to preventing Achilles tendon rupture.

BACKGROUND: Patients and healthcare professionals extensively rely on the internet for medical information. Low-quality videos can significantly impact the patient-doctor relationship, potentially affecting consultation efficiency and decision-making process. Chat Generative Pre-Trained Transformer (ChatGPT) is an artificial intelligence application with the potential to improve medical reports, provide medical information, and supplement orthopedic knowledge acquisition. This study aimed to assess the ability of ChatGPT-4 to detect deficiencies in these videos, assuming it would be successful in identifying such deficiencies. MATERIALS AND METHODS: YouTube was searched for 'rotator cuff surgery' and 'rotator cuff surgery clinic' videos. A total of 90 videos were evaluated, with 40 included in the study after exclusions. Using the Google Chrome extension '' YouTube Summary with ChatGPT & Claude'', transcripts of these videos were accessed. Two senior orthopedic surgeons and ChatGPT-4 evaluated the videos using the rotator cuff surgery YouTube score (RCSS) system and DISCERN criteria. RESULTS: ChatGPT-4's RCSS evaluations were comparable to those of the observers in 25% of instances, and 40% for DISCERN. The interobserver agreement between human observers and ChatGPT-4 was fair (AC1: 0.575 for DISCERN and AC1: 0.516 for RCSS). Even after correcting ChatGPT-4's incorrect answers, the agreement did not change significantly. ChatGPT-4 tended to give higher scores than the observers, particularly in sections related to anatomy, surgical technique, and indications for surgery. CONCLUSION: The use of ChatGPT-4 as an observer in evaluating rotator cuff surgery-related videos and identifying deficiencies is not currently recommended. Future studies with trained ChatGPT models may address these deficiencies and enable ChatGPT to evaluate videos at a human observer level.
RESUMO
BACKGROUND AND OBJECTIVE: Artificial intelligence (AI) advancements continue to have a profound impact on modern society, driving significant innovation and development across various fields. We sought to appraise the reliability of the information offered by Chat Generative Pre-Trained Transformer (ChatGPT) regarding diseases commonly associated with sports surgery. We hypothesized that ChatGPT could offer high-quality information on sports-related diseases and be used in patient education. METHODS: On September 11, 2023, specific sports surgery-related diseases were identified to ask ChatGPT-4 (personal communication, March 4, 2023). The informative texts provided by ChatGPT were recorded by a non-observer senior orthopedic surgeon for this study. Ten texts provided by ChatGPT related to sports surgery diseases were evaluated blindly by two observers. Observers assessed and scored these texts based on the sports surgery-specific scoring (SSSS) and DISCERN criteria. The precision of the disease-related information offered by ChatGPT was evaluated. RESULTS: The calculated average DISCERN score of the texts in the study was 44.75 points and the average SSSS score was 13.3 points. In the interclass correlation coefficient analysis of the measurements made by the observers, the agreement was found to be excellent (0.989; p < 0.001). CONCLUSION: ChatGPT has the potential to be used in patient education for sports surgery-related diseases. The potential to provide quality information in this regard seems to be an advantage.
RESUMO
Objective The advent of the Internet has provided new, easily accessible resources for patients seeking additional health information. Many doctors and healthcare organizations post informative videos on this platform, and nearly all patients are looking for videos online for a second opinion. Methods The phrases "frozen shoulder," "frozen shoulder treatment," "adhesive" capsulitis, and "adhesive capsulitis treatment" were entered into YouTube's search bar for a normal inquiry. The informativeness and overall quality of the adhesive capsulitis videos were rated using three separate scales. Results The mean and standard deviation values of the scoring systems were JAMA 1.25 ± 0.51, DISCERN 39.4 ± 13.4, GQS 2.83 ± 0.96 and ACSS 7.43 ± 4.86, respectively. Number of views, rate of views, and likes all had a positive correlation with Global Quality Score (GQS), as did DISCERN and ACSS. There was no statistically significant difference between the median JAMA, GQS score and Discern Criteria values according to the video source/uploader (p > 0.05). Conclusion YouTube videos on adhesive capsulitis, thus, need to be of higher quality, reliability, and instructive quality. There is a need for reliable videos about adhesive capsulitis, with instructional and high-quality cited.
RESUMO
OBJECTIVES: The aims of this study were to compare the patient and fracture characteristics, radiological, functional, and quality of life outcomes; the need for a lateral window approach and requirement of total hip arthroplasty; and complications in patients with simple and complex acetabular fractures who underwent a modified Stoppa approach through vertical and Pfannenstiel incisions. DESIGN: This was a retrospective comparison study. SETTING: Level 1 trauma center. PATIENT SELECTION CRITERIA: Patients with acetabular fractures (A-O-/-O-T-A type 62A-B-C) treated with vertical (group V) or Pfannenstiel (group P) incision-modified Stoppa approach between 2010 and 2020 were included. OUTCOME MEASURES AND COMPARISONS: Patient characteristics, radiological evaluations (reduction quality and posttraumatic osteoarthritis), patient functional outcomes [12-item Short-Form Survey (SF-12) physical component score, SF-12 mental component score, Harris Hip Score, and Merle d'Aubigné-Postel], approach modifications and stratification by fracture type and complications were compared between those treated with vertical or Pfannenstiel incisions. RESULTS: One hundred four patients (mean age of 38.5 ± 14.3 years) were included. There was no significant difference between the Pfannenstiel or vertical groups regarding patient and fracture characteristics (P = 0.137), postoperative reduction quality (P = 0.130), or the mean functional and quality of life outcome scores at the last follow-up (P = 0.483 for the Harris Hip Score, P = 0.717 for the Merle d'Aubigné-Postel score, P = 0.682 for the SF-12 physical component score, and P = 0.781 for the SF-12 mental component score). In group P, significantly more patients needed additional lateral incisions (40.8% vs. 10.9%; P 0.001) and total hip replacement procedures (12.2% vs. 1.8%; P = 0.049). The total, early, and late complication rates were significantly higher in group P (P 0.001, P = 0.034, and P = 0.049, respectively). CONCLUSIONS: Pfannenstiel incision was associated with higher complication rates than vertical incision in acetabular fractures treated through a modified Stoppa approach. Fracture complexity is associated with the need for a lateral window approach and total hip arthroplasty, as well as a worse functional and radiological outcome regardless of incision type. However, it was not associated with the development of intraoperative or postoperative complications. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

PURPOSE: To investigate the histological and biomechanical effects of a fibroblast growth factor (FGF-2)-soaked collagen membrane used to treat a full-thickness chronic rotator cuff (RC) rupture in a rabbit model. METHODS: Forty-eight shoulders from 24 rabbits were used. At the beginning of the procedure, 8 rabbits were killed to assess the control group (Group IT) with intact tendons. To establish a chronic RC tear model, a full-thickness subscapularis tear was created on both shoulders of the remaining 16 rabbits and left for 3 months. The transosseous mattress suture technique was used to repair tears in the left shoulder (Group R). The tears in the right shoulder (Group CM) were treated using the same approach, with an FGF-soaked collagen membrane inserted and sutured over the repair site. Three months after the procedure, all rabbits were killed. Biomechanical testing was performed on the tendons to determine failure load, linear stiffness, elongation intervals, and displacement. Histologically, the modified Watkins score was used to evaluate tendon-bone healing. RESULTS: There was no significant difference among the three groups in terms of failure load, displacement, linear stiffness, and elongation (P > .05). The total modified Watkins score was not affected by applying the FGF-soaked collagen membrane to the repair site (P > .05). Fibrocytes, parallel cells, large-diameter fibers, and the total modified Watkins score were significantly lower in both repair groups when compared to the intact tendon group (P < .05). CONCLUSIONS: In addition to tendon repair, FGF-2 soaked collagen membrane -application at the repair site provides neither biomechanical nor histological advantages in the treatment of chronic RC tears. CLINICAL RELEVANCE: FGF-soaked collagen membrane augmentation provides no impact on the chronic RC tear healing tissue. The need to investigate alternative methods that may have a positive effect on healing in chronic RC repairs continues.

INTRODUCTION: The development of fracture gap during intramedullary nailing in tibial fractures is associated with poor fracture fragment contact and increased time to union and complications. This study aimed to evaluate the effect of the fracture level in the development of the fracture gap and the effect of the fracture gap on pain, radiologic and functional outcomes, and complication rate. MATERIAL AND METHOD: A total of 45 patients who underwent reamed intramedullary nailing due to closed transverse or short oblique tibial shaft fractures were divided into the proximal fracture group and the distal fracture group. The correlations between the visual analog scale (VAS) score, modified radiograph union score for tibias (RUST), and postoperative 1-year lower extremity functional scale scores, residual fracture gap, and time to union were evaluated. RESULTS: The mean fracture gap amounts in the immediate postoperative anteroposterior and lateral radiographs were 5.6 ± 1.7 and 6.0 ± 1.7 mm in proximal fractures and 0.3 ± 2.4 mm and 0.4 ± 2.3 mm in distal fractures, respectively (p < 0.001 and p < 0.001, respectively). The mean time to union was 21.9 ± 2.9 weeks in the proximal fracture group and 16.7 ± 2.4 weeks in the distal fracture group (p < 0.000). The residual fracture gap amount significantly correlated with the level of fracture (r = 0.811, p < 0.001). DISCUSSION: Tibial shaft fractures proximal to the isthmus level tend to develop significantly larger fracture gaps than distal fractures. It is associated with increased time to union and radiographic union scores as well as slightly higher complication and reoperation rates.
RESUMO
BACKGROUND: Patients frequently use YouTube to learn about their illness. For this reason, the educational and quality of YouTube videos about various diseases has been investigated. In this study, we aimed to evaluate the accuracy and quality of YouTube videos. METHODS: A standard query was performed on the YouTube database using the following search terms: Plantar fasciitis, heel spur, and calcaneal spur. For each search term, the top 50 videos determined by YouTube's "relevance" according to its algorithm were evaluated (150 videos in total). After exclusion, 140 videos were included in the study. These videos were watched by 2 observers and the videos were evaluated and scored according to the Global Quality Score (GQS), DISCERN, Journal of the American Medical Association (JAMA), and Plantar Fasciitis and Calcaneal Spurs Specific Score (PFSS) scoring systems. RESULTS: According to the JAMA criteria, 76.42% of the videos and 43.57% of the videos according to the GQS scored 2 points or less. According to DISCERN criteria, 67.15% of the videos were evaluated as very poor/poor. According to the PFSS, 83.5% of the videos were rated as poor or very poor. CONCLUSIONS: These findings can be interpreted as the general information content of the videos about plantar fasciitis is insufficient and their reliability and quality are low. As a result, it can be concluded that the quality and reliability of YouTube videos regarding plantar fasciitis are insufficient for patients. Universities/associations prepare videos that provide information about plantar fasciitis to patients, and that these videos are presented on certain platforms can be a solution.

PURPOSE: To identify fracture characteristics and zones of comminution as well as the relationship with anatomic landmarks and rotator cuff footprint involvement in OTA/AO 11C3-type proximal humerus fractures. METHODS: Computed tomography images of 201 OTA/AO 11C3 fractures were included. Fracture lines were superimposed to a 3D proximal humerus template, created from a healthy right humerus, after fracture fragment reduction on 3D reconstruction images. Rotator cuff tendon footprints were marked on the template. Lateral, anterior, posterior, medial, and superior views were captured for the interpretation of fracture line and comminution zone distribution as well as to define the relationship with anatomic landmarks and rotator cuff tendon footprints. RESULTS: A total of 106 females and 95 males (mean age = 57.5 ± 17.7 [range 18-101] years) with 103 C3.1-, 45 C3.2-, and 53 C3.3-type fractures were included. On the lateral, medial, and superior humeral surfaces, fracture lines and comminution zones were distributed differently in 3 groups. Tuberculum minus and medial calcar region were significantly less severely affected in C3.1 and C3.2 fractures than C3.3 fractures. The supraspinatus footprint was the most severely affected rotator cuff footprint area. CONCLUSIONS: Specifically defining the certain differences for repeatable fracture patterns and comminution zones in OTA/AO 11C3-type fractures and the relationship between the rotator cuff footprint and the joint capsule may contribute to the decision-making process of surgeons.

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.

BACKGROUND: Sacral fractures are uncommon and understanding three-dimensional morphology is needed to obtain proper treatment. The purpose of this study was to identify the repeatable fracture patterns and comminution zones for traumatic sacral fractures and create fracture maps. METHODS: Computerized tomography images of 72 patients with traumatic sacral fracture were included in the study. For each fracture, fracture lines were identified and digitally reduced. All fractures were superimposed over a template and fracture maps; comminution zones and heatmaps were created for each zone. RESULTS: There were 40 males and 32 females with a mean age of 46.5±19.9. Fifty-three (73.6%) patients sustained major trauma, and 19 (26.4%) had minor trauma. There were 37 (51.4%) Zone 1, 22 (30.6%) Zone 2, and 13 (18.1%) Zone 3 fractures. Each Denis zone showed certain fracture patterns. In Zone 1 fractures, most of the fracture lines were vertical and oblique (up to 45°) orientation on both sides. In Zone 2 fractures, fracture lines were concentrated on the S1 and S2 levels. Anterolateral and posterolateral parts of the sacrum were less affected in right-side fractures. In Zone 3 fractures, fractures were concentrated in S1, S2, and S3 levels around the sacral canal. The median sacral crest and midline remained mostly unaffected. CONCLUSION: Sacral fractures showed specific repeatable patterns for each zone. These findings may be helpful for pre-operative planning, placement of fixation material, design of new implants, and modification of current fracture-classification systems.

BACKGROUND: Medical professionals and patients commonly use the YouTubeTM platform in their research on health information. The quality of videos about talus osteochondral defect (OCD) and arthroscopic surgery has not been evaluated previously. The aim of this study was to interpret the quality and sufficiency of YouTubeTM videos about talus OCD and arthroscopic surgery. METHODS: The present study is a quality control study of videos on OCD and their arthroscopic treatment. The videos were interpreted in terms of Journal of the American Medical Association (JAMA), DISCERN (Quality Criteria for Consumer Health Information), The Global Quality Score (GQS) and Talus OCD - Specific Score (TOCDSS) by two blinded observers to assess the accuracy of these methods. RESULTS: Inter-observer agreement was "very high" for JAMA, DISCERN, and TOCDSS, while "high" for GQS. There was a statistical relationship and a positive correlation between the scoring systems. CONCLUSION: The content and quality of YouTubeTM videos about talus OCD and arthroscopic treatment are insufficient.

PURPOSE: To characterize the fracture patterns of acetabular fractures and create fracture maps and comminution zones based on three-dimensional (3D) computed tomography (CT) images. METHODS: Sixty-eight computed tomography images of 67 patients (47 male [70.1%] and 20 female [29.9%], mean age: 45.2 ± 17.2 [range, 18-85 years] with the diagnosis of intra-articular acetabulum fracture were analyzed. Individual fracture lines were drawn and superimposed to a healthy acetabular template according to Judet-Letournel and simplified fracture classification systems. Fracture line, comminution zone, and heat maps were created using the computed tomography mapping technique. RESULTS: Fracture lines were distributed mainly in a horizontal and oblique orientation, which concentrated in the anteroinferior part of the joint in anterior fractures. Posterior fractures mostly had an oblique orientation, which lied between the acetabular dome and middle part of the posterior wall. In complex fractures, fracture lines were concentrated just above the cotyloid fossa, acetabular dome, and posterosuperior part of the acetabulum. The most common comminuted zones were around the central area of the articular surface and the anterior wall in anterior fractures, between the cotyloid fossa and dome in complex fractures, and the upper half posterior wall. CONCLUSION: Fracture patterns and comminution zones of acetabular fractures displayed certain characteristics. Some areas had higher comminution zones, and some areas remained intact in repeatable fracture patterns. These results may help surgeons in fixing acetabular fractures, designing new implants, and placement of acetabular component while performing THA after acetabular fractures.

The aim of the study was to evaluate the changes in psoas major (PM), erector spinae (ES), multifidus (MF), and rectus abdominis (RA) morphometry in Lenke type V adolescent idiopathic scoliosis (AIS) and control. Forty-two Lenke V AIS patients and 30 control were enrolled. The cross-sectional area (CSA) and CSA index (CI) of the PM, ES, MF, and RA at the T9-L5 levels were measured and compared between Lenke type V patients and control. The CI of the RA was significantly higher in the control group than the Lenke V group in multiple levels. On the other hand, there was no significant difference between patients with Lenke V AIS and control regarding the CI of the RA, ES, and PM. There was no significant difference between concave and convex sides of the Lenke V group regarding the CI of the RA, PM, MF, and ES. RA muscle mass is significantly affected in Lenke type 5 AIS regardless of convex or concave sides. This difference may be related to postural differences and back pain development in Lenke type 5 patients. Level of evidence: Level III.

BACKGROUND: The fact that lateral malleolar fracture is accompanied by posterior malleolar fracture may adversely affect syndesmosis malreduction rates. We aimed to compare syndesmosis malreduction rates determined on postoperative radiographs between isolated lateral malleolar fractures and lateral malleolar fractures accompanied by posterior malleolar fractures. METHODS: We retrospectively examined 128 operative patients: 73 with isolated lateral malleolar fractures (group L) and 55 with lateral + posterior malleolar fractures (group LP). In group LP, no patients received posterior fragment fixation. In both groups, indirect syndesmosis fixation was performed with a single screw after open reduction and internal fixation of the lateral malleolus. Patient age, sex, fracture side, fracture type (Lauge-Hansen and Danis-Weber classifications), Kellgren-Lawrence osteoarthritis classification, syndesmotic incongruency on postoperative radiographs, syndesmotic malreduction of postoperative fibula fracture, fracture union time, complication rates, accompanying injuries, and preoperative and postoperative radiographic syndesmotic measurements (tibiofibular overlap, tibiofibular clear space, medial clear space) were recorded, and the groups were compared. RESULTS: Mean ± SD age was 44.32 ± 15.66 years in group L and 48.93 ± 14.03 years in group LP (P = .087). There were no significant differences in preoperative and postoperative tibiofibular distance, tibiofibular overlap, and medial clear space values between groups (P > .05). The prevalence of grade 2 fractures according to the Kellgren-Lawrence classification was significantly higher in group LP (P = .047). Postoperative syndesmosis malreduction was detected in 12 patients in group L and in nine in group LP (P = .991). CONCLUSIONS: In lateral malleolar fractures accompanied by small-fragment posterolateral or avulsion-type posterior malleolar fractures, closed syndesmotic screw fixation does not cause syndesmosis malreduction.

Background: In Professional Athletes, quadriceps and patellar tendon ruptures are devastating injuries, often resulting in the loss of a season or a decreased return to the pre-injury level of sport. This study aimed to perform a comprehensive Video Analysis on extensor mechanism rupture (EMR) to describe the body postures and related mechanism in Professional Athletes. Methods: Using publicly available data on quadriceps tendon and patellar tendon ruptures from between 2000 and 2020, 52 elite athletes were identified. Of these, twenty-eight injuries with adequate video data were analyzed for Injury Mechanism, body posture, as well as player and sports characteristics. Results: Of the 27 athletes included in the study, with an average age of 28.18 ± 4.96 years, there were injuries in 28 extremities (1 case bilateral). The patellar tendon was ruptured in 20 cases (71.4%), and the quadriceps tendon in 8 cases (28.6%). There was total tendon rupture in 13 cases, and partial rupture in 6 cases (data for 1 case was not available). In 20 cases (70.4%), there was no contact resulting in the injury. Four of the contact injuries occurred in American football (3 direct, one indirect), 3 in basketball (1 direct, two indirect), and 1 in baseball (direct). Conclusion: The results of this research indicate that EMR occurs most commonly when the knee is in flexion and the ankle is in plantar flexion. There is the tendency for the knee to be in valgus at the time of injury. This information can guide physical therapy techniques, including neuromuscular training, proprioception, and balance training in the prevention of EMR in elite athletes.
RESUMO
Background: Muscle and bone morphometry may be potent indicators for predicting femoral subtrochanteric shortening osteotomy (FSSO). We aimed to investigate muscular and bony factors that may be predictive of FSSO. Methods: Patients with unilateral Crowe type 4 developmental dysplasia of the hip (DDH) who underwent unilateral total hip arthroplasty (THA) without (Group 1, 31 patients) and with FSSO (Group 2, 39 patients) were included. Sixty healthy hips (Group 3) were selected as the control group. Several muscular and bony parameters were measured on the operative (O) and non-operative (NO) hips on radiographs and computed tomography (CT) images. Results: The mean NO gluteus medius cross-sectional area (CSA) index (NO-GMed CI), NO tensor fasia lata (TFL) CI, NO iliopsoas (IP) CI, and NO gluteus maximus (GMax) CI for the control group were lower than those for both Crowe type IV DDH with and without FSSO. The mean NO gluteus minimus CI (NO-GMin CI) for the control group were higher than those for both Crowe type IV DDH with and without FSSO. There was significant difference between Groups 1 and 2 regarding axial position of neo-acetabulum (APNA) (- 0.03 ± 8.5 vs. 5.27 ± 6.33, p = 0.004), coronal position of neo-acetabulum (CPNA) (33.39 ± 10.65 vs. 53.70 ± 12.27, p = 0.000), operative leg length discrepancy (O-LLD) (14.18 ± 15.14 vs. 24.44 ± 15.80, p = 0.001), O-gluteus minimus (GMin) length (155.34 ± 157.73 vs. 106.79 ± 20, p = < 0.01), and O-GMin CI (57.28 ± 58.59 vs. 29.95 ± 12.13, p = < 0.01). The cutoff values determined by the receiving operating curve analyses were as follows: 13.7 mm, 2.5 mm, and 41.4 mm for O-LLD, APNA, and CPNA, respectively. Conclusion: FSSO is associated with APNA, CPNA, O-LLD, O-GMin length, and O-GMin CI. By using cutoff values of APNA, CPNA, and O-LLD, predicting FSSO preoperatively is possible. Owing to these parameters, it may be possible to lower the technically demanding level of surgery.
RESUMO
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.

BACKGROUND: Although several factors are associated with anterior cruciate ligament (ACL) rerupture, the effect of anatomic factors associated with ACL rupture on ACL rerupture development has not been evaluated. PURPOSE: To determine individual anatomic parameters independently associated with ACL rerupture and the diagnostic values of these parameters. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: A total of 91 male patients with ACL rerupture and 182 age-, sex-, body mass index-, and side dominance-matched patients without rerupture who underwent ACL reconstruction with a 5-year follow-up were included. In all, 35 parameters that were previously defined as risk factors for primary ACL rupture were compared between the 2 groups. Uni- and multivariate logistic regression models were created to evaluate independently associated factors. Receiver operating characteristic curve analysis was performed for independently associated parameters to predict sensitivity, specificity, and cutoff values. RESULTS: The mean ± standard deviation age of patients at the time of index surgery was 26.5 ± 6.7 years. Notch shape index (P = .014), tibial proximal anteroposterior (AP) distance (TPAPD) (P < .001), lateral femoral condylar AP distance (LCAPD)/TPAPD ratio (P < .001), medial meniscal cartilage bone height (P < .001), and lateral meniscal bone angle (P = .004) were found to be significantly different between the 2 groups. Only the LCAPD/TPAPD ratio (odds ratio, 2.713; 95% CI, 1.998-5.480; P < .001) was found to be independently associated with ACL rerupture development. The LCAPD/TPAPD ratio revealed 78.9% sensitivity and 75.5% specificity (area under the curve, 0.815; 95% CI, 0.760-0.870) for values above 1.52. CONCLUSION: The LCAPD/TPAPD ratio can be used to distinguish patients who are at risk of developing ACL rerupture from patients who are not. In the clinical practice, findings of this study may help to develop surgical and nonsurgical preventive strategies in ACL rerupture development.
