Fractures of the acetabulum are one of the most challenging injuries treated by orthopedic surgeons. However, a bibliometric analysis has not been performed in the literature on acetabular fractures, which seriously affect the quality of life of patients. The aim of this study was to summarize the bibliometric and intellectual structure, and determine and map the most recent trends on the topic of acetabular fractures by analyzing the social and structural relationships between the different research components of articles published on the acetabular fractures. 1599 articles on acetabular fractures published between 1980 and 2022 were extracted from the Web of Science (WoS) database and analyzed. Bibliometric visualization maps were used to reveal trending topics, citation analyses, and international collaborations. Spearman correlation analysis was performed for correlation investigations. The trend in the expected number of articles to be published over the next few years was displayed using the exponential smoothing estimator. The top 3 contributing countries to the literature were United States of America (USA) (551, 34.4%), China (170, 10.6%), and Germany (160, 10%). The most active author was Berton R. Moed (n = 29) and the most active institution was the University of California System (n = 41). A high-level statistically significant correlation was found between the number of articles on the topic of acetabular fractures published by nations and the gross domestic product (GDP) and GDP per capita values of those countries ( R = 0.719, P < .001; R = 0.701, P < .001, respectively). The trending topics researched in recent years were 3D printing, 3-dimensional printing, outcomes, Open Reduction and Internal Fixation (ORIF), mortality, Kocher-Langenbeck, Pararectus approach, tranexamic acid, transfusion, epidemiology, fracture mapping, modified Stoppa approach, post-traumatic osteoarthritis, pelvis fracture, pelvic trauma, fracture reduction, and pelvic ring injury. The leading countries in research on the subject of acetabular fractures were seen to be western countries with large economies (especially the USA, European countries, and Canada) and China, India and Turkey.

Is it possible for a low-volume surgeon to enhance their surgical skills without performing actual surgeries by utilizing virtual reality headsets and emerging technologies? It has been observed that the time spent by surgical assistants in the operating room decreased after the post-shift leave regulation. In the literature, the use of virtual reality simulations as a support tool in surgical training is recommended. Although the efficacy of virtual reality surgical simulations in surgeries such as arthroscopy and laparoscopy has been proven, there are limited studies on their effect in open surgeries. In this study, 20 orthopedic and traumatology residents with no experience in primary total knee arthroplasty were divided into 2 groups. One group was prepared for surgery using surgical simulation with virtual reality headsets, while the other group was prepared for surgery with traditional methods. The actual surgical performance of the participants was evaluated with the Objective Structured Scale of Technical Skills (OSATS) surgical skills scale. It was observed that the virtual reality group was more successful in the “Time and Motion” and “Surgical Functioning and Fluency” criteria. Virtual reality surgical simulations are useful tool in surgical training and can contribute to the development of surgeons’ skills. However, more research is needed on how to integrate these simulations into training programs and in which areas they are most effective.

Introduction: Anterior cruciate ligament (ACL) ruptures are common injuries that typically affect young, physically active individuals and may require surgical reconstruction. Studies have shown that the long time success of ACL reconstruction depends on the surgical technique and the postoperative rehabilitation strategy. However, there is still no consensus on the content of rehabilitation programs. Hence, additional research is required to elucidate the significance of early weight-bearing in the rehabilitation process following ACL reconstruction. The aim of this article is to examine the impact of weight-bearing on the clinical results of ACL reconstruction. Materials and methods: We retrospectively reviewed patient records who had undergone arthroscopic reconstruction using a semitendinosus-gracilis tendon graft for anterior cruciate ligament rupture between January 2018 and December 2020. The study included the data of 110 patients. The patients were split into two groups: Group 1 underwent early weight-bearing, while Group 2 followed a non-weight-bearing regimen for three weeks. We assessed the patients using the anterior drawer test, Lachman test, range of motion, Lysholm knee scale, Cincinnati scale, Tegner scale, International Knee Documentation Committee (IKDC) form and clinical records. Analytical tests were conducted to compare the results. Results: The complication rates did not show a significant difference between the groups. Group 1 had higher frequencies of positive anterior drawer and Lachman tests. The Lysholm and Cincinnati knee scores of patients in Group 1 were notably lower than those of patients in Group 2. Additionally, the Tegner activity scores and IKDC scores of patients in Group 1 were also meaningfully lower than those of patients in Group 2. In Group 1 patients, there was no notable relationship observed between body mass index (BMI) and the results of the anterior drawer test (ADT) or Lachman test. However, patients with a BMI of 25 or higher in Group 1 showed a decrease in postoperative IKDC scores. In Group 2 patients, no significant relationship was identified between BMI and either the ADT or the Lachman test outcome. Conclusion: Based on current literature and current rehabilitation guidelines following ACL reconstruction, the decision to initiate early weight-bearing is based on a limited number of studies with low levels of evidence. In our study, we found that patients who followed a non-weight-bearing regimen for 3 weeks after surgery had better mid-term results than those who were allowed to bear weight early. It appears that further prospective studies on this topic are needed to update rehabilitation guidelines in the next.

Background: This study aimed to reveal the posterior tibial slope (PTS) angle with 3 different methods in a large case group in the Turkish population. In addition, the reproducibility of the measurement methods used was questioned while determining the age groups, gender and side relationship of this angle. Materials and methods: In our retrospective study, radiographs of both knees were evaluated in all 610 patients (344 women, 56.4%) aged 25–65 years. PTS angles were measured by a radiologist and an orthopedist using anterior tibial cortex (ATC), posterior tibial cortex (PTC) and proximal tibial anatomical axis (PTAA) methods. The relationship of these angles with age group and gender, and the intra-class and inter-class correlations of all three methods were evaluated. Results: The mean and standard deviation (SD) of PTS angle was 11.03 ± 2.33° with ATC method, 6.25 ± 2.22° with PTC and 8.68 ± 2.16° with PTAA, and the difference was significant (p < .001). In the evaluation according to age groups, the highest mean PTS angles were detected in cases aged 25–35 (9.63 ± 1.97° [mean ± SD] by PTAA method), and there was a significant difference in comparison with other age groups (p < .05). In comparison with age groups, higher mean PTS angles were found in women and on the right side, but the difference was not statistically significant (p > .05). The intraclass and interclass correlation coefficient (ICC) of all three methods was excellent (ICC > 0.91). Conclusion: This study emphasizes that the mean PTS angle in Turkish population is higher than the angle values ​​recommended by prosthesis manufacturers, and factors such as patient age and gender should be calculated in order to ensure more effective prostheses to be applied to patients.

Rhabdomyolysis can occur due to many traumatic and nontraumatic causes. Rhabdomyolysis has been reported in new type of coronavirus disease (COVID-19) cases. The aim of our study was to examine the effects of rhabdomyolysis on mortality and renal outcomes in patients hospitalized in our hospital’s COVID-19 wards. In our single-center and retrospective study, we included patients who were admitted with a diagnosis of COVID-19 by a thorax-computed tomography finding who were older than 18 years of age and with a measured creatinine kinase (CK) > 1000 U/L on any day of hospitalization. The same number of patients hospitalized in COVID-19 services with CK < 1000 U/L and with similar gender and age were determined as the control group. We analyzed the data of 2065 patients, and compared 154 patients in the rhabdomyolysis group (group 1) and 154 patients in the control group (group 2). Acute kidney injury (AKI) (44.2% vs 21.4%; P < .001), intensive care unit (ICU) admissions (53.2% vs 13.6%; P < .001), intubation (75.6% vs 23.8%; P < .001), mortality (36.4% vs 3.2%; P < .001) and the need for dialysis (3.9% vs 0.6%; P = .005) were seen more in the rhabdomyolysis group. When that group was divided into the early rhabdomyolysis group (group 1a), where the CK value reached its highest value in ≤3 days, and the late rhabdomyolysis group (group 1b), where it was ≥ 4 days, AKI (29.7% vs 65.1%; P < .001), ICU (35.2% vs 79.4%; P < .001), intubation (56.2% vs 88%; P = .001), mortality (18% vs 61.9%; P < .001), and dialysis (1.1% vs 7.9%; P = .031), the results were higher in the group 1b. The available data suggest that rhabdomyolysis seen in COVID-19 patients is not a direct predictor of mortality and poor renal outcomes, but is a secondary outcome to multiple-organ failure caused by worsening clinical status.
