Article Citation - WoS: 3Citation - Scopus: 3The Metaverse in Orthopaedics: Virtual, Augmented and Mixed Reality for Advancing Surgical Training, Arthroscopy, Arthroplasty and Rehabilitation(Wiley, 2025) Kayaalp, Mahmut Enes; Konstantinou, Efstathios; Karaismailoglu, Bedri; Lucidi, Gian Andrea; Kaymakoglu, Mehmet; Vieider, Romed; Hirschmann, Michael T.PurposeThe metaverse and extended reality (XR), which includes augmented reality (AR), virtual reality (VR) and mixed reality (MR), are transforming orthopaedic surgery by enhancing training, procedural accuracy and rehabilitation. However, a literature review of these new virtual tools is lacking. The purpose of this narrative review is to summarise available evidence about the metaverse and discuss current and future clinical applications.MethodsA narrative review of the current literature was performed for studies evaluating XR tools and their respective clinical and educational utility. Studies from all orthopaedic subspecialties were eligible for inclusion. The XR tools evaluated in each study were categorised according to the reality spectrum and future research or clinical applications were discussed.ResultsXR is a technological spectrum that includes AR, VR and MR to create immersive and interactive surgical training environments. VR-based simulators may improve surgical education by allowing trainees to refine their skills in a risk-free setting. AR may enhance intraoperative guidance and has been studied within orthopaedics to improve implant positioning accuracy and reduce complications in procedures including arthroscopy and total joint arthroplasty. In rehabilitation, AR and VR have been implemented to facilitate patient engagement and adherence, promoting functional recovery through gamified therapy and remote telerehabilitation.ConclusionsThere has been a paradigm shift in orthopaedic care in which digital tools are integrated with patient care to optimise patient outcomes. However, challenges to the widespread implementation of promising XR technology include high costs, steep learning curves and limited clinical validation. Ethical concerns, including data security and patient privacy, further complicate its use in clinical settings. Future research must focus on cost-effectiveness, standardisation and improving accessibility to ensure seamless integration into clinical practice.Level of EvidenceLevel V.Article Citation - WoS: 9Citation - Scopus: 11Can Popular AI Large Language Models Provide Reliable Answers to Frequently Asked Questions About Rotator Cuff Tears(Elsevier, 2025) Kolac, Ulas Can; Karademir, Orhan Mete; Ayik, Gokhan; Kaymakoglu, Mehmet; Familiari, Filippo; Huri, GaziBackground: Rotator cuff tears are common upper-extremity injuries that significantly impair shoulder function, leading to pain, reduced range of motion, and a decrease in quality of life. With the increasing reliance on artificial intelligence large language models (AI LLMs) for health information, it is crucial to evaluate the quality and readability of the information provided by these models. Methods: A pool of 50 questions was generated related to rotator cuff tear by querying popular AI LLMs (ChatGPT 3.5, ChatGPT 4, Gemini, and Microsoft CoPilot) and using Google search. After that, responses from the AI LLMs were saved and evaluated. For information quality the DISCERN tool and a Likert Scale was used, for readability the Patient Education Materials Assessment Tool for Printable Materials (PEMAT) Understandability Score and the Flesch-Kincaid Reading Ease Score was used. Two orthopedic surgeons assessed the responses, and discrepancies were resolved by a senior author. Results: Out of 198 answers, the median DISCERN score was 40, with 56.6% considered sufficient. The Likert Scale showed 96% sufficiency. The median PEMAT Understandability score was 83.33, with 77.3% sufficiency, while the Flesch-Kincaid Reading Ease score had a median of 42.05 with 88.9% sufficiency. Overall, 39.8% of the answers were sufficient in both information quality and readability. Differences were found among AI models in DISCERN, Likert, PEMAT Understandability, and Flesch-Kincaid scores. Conclusion: AI LLMs generally cannot offer sufficient information quality and readability. While they are not ready for use in medical field, they show a promising future. There is a necessity for continuous reevaluation of these models due to their rapid evolution. Developing new, comprehensive tools for evaluating medical information quality and readability is crucial for ensuring these models can effectively support patient education. Future research should focus on enhancing readability and consistent information quality to better serve patients. (c) 2024 The Author(s).

Methods: A standard YouTube search was performed in March 2023 using the terms “shoulder dislocation,” “dislocated shoulder,” and “glenohumeral joint dislocation” to identify eligible videos. Multiple scoring systems, including DISCERN (a validated tool for analyzing the quality of health information in consumer-targeted videos), Journal of the American Medical Association (JAMA) Benchmark Criteria, and the Global Quality Score (GQS) were used to evaluate the videos. Video quality scores from various sources were compared using the Kruskal-Wallis test for initial analysis, followed by Dunn's post-hoc test with Bonferroni correction, and the strength of relationship between variables was assessed using Spearman's rank correlation coefficient. Results: A total of 162 eligible videos were identified. The mean video duration was 11.38 ± 3.01 minutes, the median number of views was 653. Median number of days since upload was 1,972, the median view rate was 0.343, and median number of likes was 66.12. Based on the DISCERN classification, a substantial proportion of videos were classified as insufficient quality, with 19.4% as “very insufficient” and 42.1% as “insufficient”; 24.1% were classified as “average” quality, whereas only 13.1% were classified as “good” and 1.2% were “excellent.” Videos from academic and professional sources showed a significant positive correlation with DISCERN scores (rho: +0.784, P < .001) and greater scores on all 4 scoring systems compared to health information websites. Conclusions: This study reveals that the majority of YouTube videos on shoulder dislocation lack sufficient quality for patient education, with content quality significantly influenced by the source. Clinical Relevance: Examining the accuracy of information that patients encounter on YouTube is essential for health care providers to direct individuals toward more reliable sources of information. © 2024 The AuthorsBook Part Superior Labrum Anterior and Posterior Lesions: Evaluation and Treatment(Springer Science+Business Media, 2025) Huri, G.; Hyun, Y.S.; McFarland, E.; Karahan, M.; Kaymakoğlu, M.; Oytun, I.; Ankem, H.Superior labral lesions are a common occurrence in athletes, but they also are seen in individuals who do not participate in athletics. The diagnosis and treatment of superior labrum anterior and posterior (SLAP) lesions pose a major challenge to anyone who evaluates shoulders, including orthopedic surgeons and rehabilitation specialists. One of the reasons the diagnosis is difficult to ascertain is that there are often coexisting abnormalities that can produce symptoms similar to those of SLAP lesions. Even though improvement in arthroscopic techniques has allowed arthroscopic repair of SLAP lesions with suture anchors, the surgical results, especially in athletes, have not proven to be as successful as once believed. Controversies about which treatment (suture anchor fixation vs. biceps tenodesis) is more appropriate in athletes is the ongoing topic of discussion in SLAP lesions. This chapter reviews the anatomy, classification, pathophysiology, diagnosis, and treatment of SLAP lesions. © 2025 Springer Nature Switzerland AG.Letter Response to the Letter to the Editor Regarding “Can Popular Artificial Intelligence Large Language Models Provide Reliable Answers to Frequently Asked Questions About Rotator Cuff Tears?”(Elsevier B.V., 2025) Kolac, Ulas Can; Karademir, Orhan Mete; Ayık, Gökhan; Kaymakoğlu, Mehmet; Familiari, Filippo; Huri, GaziArticle Citation - WoS: 1Citation - Scopus: 1Pcl Injury Following High Energy Trauma: Associated Injuries and Postoperative Complications Insights From a National Registry Study(BMC, 2024) Bingöl, Izzet; Öktem, Umut; Kaymakoglu, Mehmet; Kolaç, Ulas Can; Birinci, Şuayip; Kamacı, SaygınPurposeThe posterior cruciate ligament (PCL) is a vital knee stabilizer. While PCL injuries are rare, high-energy traumas can lead to total ruptures, with accompanying injuries requiring surgery. This study aims to investigate the demographics, concomitant injuries, and postoperative complications of patients who underwent PCL reconstruction due to high-energy trauma in a large patient sample.MethodsPatients who underwent PCL reconstruction from 2016 to 2022 were retrospectively evaluated using data from a nationwide personal health recording system. Patient demographics, injury mechanisms, associated fractures, soft tissue injuries, and postoperative complications were collected from patient notes, clinical visits, and surgical notes. Individuals with a PCL injury following high-energy trauma (car accident, falls from height, motorcycle accident) with a minimum follow-up of 1 year were included in the study.ResultsThe study included 416 patients with a mean age of 32.4 years. Isolated PCL injuries (n = 97, 23.3%) were observed less frequently than multiple-ligament injuries (n = 319, 76.7%). Most cases were treated with single-stage surgery (86.8%), while staged surgeries were performed in a minority of cases (13.2%). There was no relationship between trauma mechanisms and multiple-ligament involvement, accompanying injuries, or postoperative complications. Surgeries following car accidents were more likely to occur as staged surgeries (p = 0.014). Additionally, the complication rates for staged surgeries and younger patients (<= 18 years) were significantly higher (p = 0.009).ConclusionHigh-energy trauma-induced PCL injuries are often associated with severe concurrent knee injuries with multiple ligament involvement. PCL reconstructions following car accidents are more likely to be staged. These findings highlight the importance of careful consideration in managing these cases to minimize complications, particularly in younger age groups.Level of evidenceLevel III.Article Toward a New Era in Fracture Imaging: Zero Echo Time MRI Vs CT in Intra-Articular Distal Radius Fractures — A Proof-of Study(Elsevier Ltd, 2025) Kaymakoğlu, M.; Kolac, U.C.; Bahsi, A.; Filibeli, M.; Türken, M.A.; Dogan, K.; Şahin, E.Background Computed tomography (CT) is the current reference standard for evaluating intra-articular distal radius fractures, however concerns remain regarding radiation exposure and limited soft tissue assessment. Zero Echo Time (ZTE) MRI is a novel technique that enables direct cortical bone imaging with contrast similar to CT, while avoiding radiation. This proof-of-concept study aimed to compare the diagnostic performance of ZTE MRI with CT in fracture classification, articular involvement, and treatment planning. Methods In this prospective comparative study, 28 patients with acute intra-articular distal radius fractures underwent both CT and ZTE MRI within 7 days of injury. Fractures were classified according to AO/OTA, Fernandez classifications, quantitative parameters (angulation, radial inclination, ulnar variance, articular fragment count) and binary findings (distal ulna fracture, distal radioulnar joint (DRUJ) involvement) were assessed. Two orthopedic surgeons and two musculoskeletal radiologists independently reviewed all images. Inter- and intraobserver agreement was calculated using Cohen’s and Fleiss’ kappa and intraclass correlation coefficients. Results Agreement among surgeons for AO/OTA classification was good on CT (κ = 0.767) and good on ZTE MRI (κ = 0.680). For Fernandez classification, agreement was good on CT (κ = 0.780) and ZTE (κ = 0.736). Surgeons demonstrated higher agreement (κ ≈0.68–0.78) than radiologists (κ ≈0.56–0.65). For binary parameters, agreement among radiologists was very good (κ = 0.820–0.880), while inter-surgeon agreement ranged from moderate to good (κ = 0.500–0.714). Continuous measures showed good reproducibility for angulation (ICC = 0.762–0.858), but lower values for inclination among surgeons (ICC ≤ 0.492–0.531). ZTE MRI demonstrated sensitivity, specificity, and accuracy comparable to CT for classification and detection of DRUJ involvement and distal ulna fractures (approximately 85–93 %). Treatment decisions showed very good agreement (κ = 0.855), with ZTE altering CT-based management in 3/28 (10.7 %) cases for Surgeon 1 and 2/28 (7.1 %) for Surgeon 2. Conclusion ZTE MRI provides diagnostic performance comparable to CT for intra-articular distal radius fractures, with high reliability for fracture classification, joint involvement, and treatment decision-making. As a radiation-free modality that also permits concurrent soft tissue assessment, ZTE MRI may serve as a promising alternative to CT in selected clinical scenarios. © 2025 Elsevier Ltd.Article Citation - WoS: 2Citation - Scopus: 2Adrenomedullin Has No Effect on Segmental Bone Defect Healing but Increases Bone Mineral Density in Rat Model(AVES, 2023) Kaymakoğlu, Mehmet; Ciftci, E.; Korkusuz, P.; Ozdemir, E.; Erden, M.E.; Turhan, E.Objective: This study aimed to investigate the effect of adrenomedullin on the healing of the segmental bone defect in a rat model. Methods: Thirty-six Wistar rats were randomly divided into 6 groups based on follow-up periods and administered a dose of adreno-medullin hormone. In each group, bilaterally, a 2-mm bone defect was created at the diaphysis of the radius. Sodium chloride solution was administered to sham groups 3 times a week for 4 and 8 weeks intraperitoneally. Adrenomedullin was administered to the study groups 3 times a week: 15 μg—4 weeks, 15 μg—8 weeks, 30 μg—4 weeks, and 30 μg—8 weeks, respectively. After euthanasia, the segmental defects were evaluated by histomorphometric [new bone area (NBA)] and microtomographic [bone volume (BV), bone surface (BS), and bone mineral density (BMD)] analyses. Results: Although the 4-and 8-week 15 μg administered study groups had higher NBA values than the other study and control groups, the histomorphometric analysis did not reveal any statistical difference between the control and study groups regarding NBA (P >.05). In microtomographic analysis, BV was higher in the 15 μg 4-week group than 30 μg 4-week group (296.9 vs. 208.5, P =.003), and BS was lower in the 30 μg 4-week group than in the 4-week control group (695.5 vs. 1334.7, P =.005), but overall, no significant difference was found between the control and study groups (P >.05). Despite these minor differences in histomorphometric and microtomographic criteria indicating new bone formation, the BMD values of the 15 μg 8-week study group showed a significant increase compared with the control group (P =.001, respectively). Conclusion: Adrenomedullin positively affected BMD at 15 μg, but this study could not show healing in the segmental defect site at different dose regimens. Further studies are needed to assess its effects on bone tissue trauma. © 2023, AVES.

These entrapments were previously considered as a diagnosis of exclusion. However, today these pathologies can be diagnosed as primary. The most common complaints of patients are pain and sometimes weakness. The clinician's suspicion is very important in making diagnosis. The patient's history, duration of symptoms, and information such as the movements in which the complaints increase should be questioned carefully and in detail. In physical examination, symmetrical evaluation of both shoulders can provide important information. In addition, cervical and brachial plexus pathologies should be kept in mind. According to the suprascapular and axillary nerve innervations, muscle atrophy should be evaluated during inspection. Range of motion and neurological examination around shoulder should be performed. Since these entrapments can be seen together with rotator cuff tears and labrum pathologies etc., these additional pathologies should also be targeted during evaluation. The evaluation should be expanded with imaging methods such as plain radiographs, ultrasonography, computed tomography, magnetic resonance imaging, electrodiagnostic studies and local anaesthetic injections to the entrapment area. There is no definitive method to diagnose these pathologies. As a result of all these evaluations, a diagnosis can be made. There is no consensus on treatment. In isolated entrapment cases where there are no additional surgical pathologies such as space-occupying lesions, non-operative treatment is primarily recommended. It is generally recommended to try non-operative treatment for at least six months. Surgical treatment is recommended in cases where non-operative treatment fails or in cases where there are additional pathologies requiring surgery or in cases where there is extrinsic compression such as sapce-occupying lesions. In the decision and choice of surgical treatment, it is very important to determine the aetiology precisely. Surgical treatment can be performed open and arthroscopically. Various additional arthroscopic portals and techniques have been described. However, there is no clear consensus on the superiority of these treatments over each other. Although physical therapy is recommended after surgical treatment, there is no consensus on this issue in the literature.AimThis review aims to summarize the diagnosis and management of suprascapular and axillary nerve entrapments in athletes, focusing on clinical presentation, diagnostic methods, treatment options, and current controversies.Article Evaluation of Sleep Quality After Reverse Shoulder Arthroplasty in Rotator Cuff Tear Arthropathy Patients(Springer, 2025) Kaymakoglu, Mehmet; Kolac, Ulas Can; Ayik, Gokhan; Ibik, Serkan; Ozdemir, Erdi; Huri, GaziPurpose Sleep disturbance is common in patients with rotator cuff tear arthropathy (RCTA). While reverse shoulder arthroplasty (RSA) is effective for improving pain and function, its effect on sleep quality (SQ) has not been well defined. This study aimed to evaluate the impact of RSA on SQ, recovery trajectory, and clinical outcomes. Methods This retrospective study included patients with RCTA who underwent RSA between 2014 and 2021 with a minimum follow-up of 24 months. SQ and clinical outcomes were assessed using the Visual Analog Scale (VAS), Simple Shoulder Test (SST), American Shoulder and Elbow Surgeons (ASES) score, Pittsburgh Sleep Quality Index (PSQI), and Jenkins Sleep Scale (JSS). Preoperative and postoperative values were compared to evaluate changes over time. Results Forty-six patients (mean age, 68 years) with a mean follow-up of 5.7 years were included. Sleep disturbance was reported by 45.7% of patients preoperatively, decreasing to 26.1% at three months and 21.7% at the last follow-up (p < 0.001). Median PSQI scores improved from 6 preoperatively to 5 at three months and remained stable thereafter. The mean ASES score increased from 40.2 preoperatively to 62.2 postoperatively (p < 0.001), and the average VAS score decreased from 6.0 to 2.0 by six months (p < 0.001). Conclusion RSA leads to improvements in sleep and function in RCTA patients, though gains plateau with time. Future studies using objective sleep measures may further refine rehabilitation outcomes.
