Background/Objectives: Evaluating basic daily activities like sitting, standing, and walking is crucial for predicting preoperative risks and postoperative recovery. These functional abilities can be assessed through patient history or measured using objective tests. For this purpose, the 30-Second Sit-to-Stand (30STS) Test and Timed Up-and-Go (TUG) Test are frequently used in clinical settings. However, few studies have evaluated their effectiveness in anesthesia and orthopedics. In this study, we aimed to assess the applicability of these tests across clinical disciplines. Methods: A total of 43 patients who underwent total knee arthroplasty (TKA) surgery between January and December 2023 with American Society of Anesthesiologists (ASA) scores of 2–3 were retrospectively evaluated. The 30STS, TUG, and VAS scores were recorded preoperatively and on postoperative days 90–180. Results: The preoperative 30STS and TUG scores showed no statistically significant difference between the ASA 2–3 groups, but the ASA 2 group demonstrated a more pronounced performance improvement in both tests during the first 90 days postoperatively. The correlation tests revealed a strong positive relationship with the TUG Test and a moderate positive relationship with the 30STS and VAS scores. Conclusions: The correlation between the preoperative and postoperative results of the 30STS and TUG Tests suggests that preoperative tests can predict post-operative functional performance. However, the lack of a significant statistical relationship between the preoperative tests and ASA scores indicates that these tests may not be sufficiently useful for assessing the functional capacity. The better test outcomes in the ASA 2 patients indicate that combining these assessments with anesthetic evaluations may improve postoperative functional predictions, thereby promoting a multidisciplinary approach.

Objectives: Total hip arthroplasty is one of the most common procedures performed to reduce pain and improve hip functions in patients with advanced hip osteoarthritis, but perioperative blood loss, acute anemia and transfusion requirement increase the risk of morbidity and mortality during and after surgery and negatively affect functional recovery. We aimed to present the comparative results of oral + topical and only topical tranexamic acid application to reduce blood loss and postoperative transfusion in primary total hip arthroplasty. Methods: We retrospectively evaluated the patients who applied to the Orthopedics and Traumatology outpatient clinic with complaints of hip pain and limited movement between January 2014 and December 2020, who underwent primary total hip arthroplasty with the diagnosis of coxarthrosis and who were administered oral + topical and only topical tranexamic acid before and during surgery, in terms of blood loss and transfusion requirement. Results: No statistically significant difference was observed between the preoperative, day 0 and day 1 hemoglobin means in those that were applied oral + topical tranexamic acid and those that were applied only topical (p > 0.05). However, the second- and third-day hemoglobin means in those that were treated with topical medication alone were found to be statistically significantly lower than in those that were treated with oral + topical tranexamic acid (p = 0.032, p = 0.0001). Conclusions: Oral + topical tranexamic acid application in total hip arthroplasty surgery is more effective than topical applications alone when it comes to reducing blood loss, hemoglobin and hematocrit decrease without increasing the risk of thromboembolic diseases and wound complications.

Background/Objectives: The correct angular placement of the tibial tunnel is crucial to ensure graft tension, maintain knee stability, and ensure optimal clinical outcomes after anterior cruciate ligament (ACL) reconstruction. While 3D imaging methods such as MRI and CT are the gold standard for evaluating tunnel positioning, their routine use is limited by cost, availability, and time constraints. In clinical practice, 2D radiographs are more accessible but lack established reliability in accurately estimating tunnel angles. The aim of this study was to convert 2D radiographic angular measurements used in the evaluation of patients undergoing anterior cruciate ligament reconstruction into 3D values with a simple method and to compare these measurements with three-dimensional angles calculated using conventional MRI and CT. Methods: This retrospective study included 38 patients who underwent anatomic anterior cruciate ligament reconstruction. Postoperative radiographs and MR images were analyzed to determine the tibial tunnel angles. The angles calculated from 2D radiographs were statistically analyzed for their correlation with the actual 3D angles measured by MRI. Results: The analysis showed a strong correlation between tibial tunnel angles from radiographs and MRI, with minimal, non-significant differences. This suggests that radiographs can provide a reliable estimate of tibial tunnel angles. Conclusions: These findings suggest that radiographs can predict tibial tunnel angles in ACL reconstruction as accurately as MRI. This method can guide the correct tunnel angle and facilitate postoperative evaluation. Further studies are needed to confirm these results across various populations and techniques.

BACKGROUND Septic and aseptic loosening are the most common indications for revision hip arthroplasty (RHA), and infection-related revisions pose significant diagnostic and management challenges. This study aims to compare septic and aseptic RHA cases in terms of inflammatory markers, prevalence of diabetes mellitus (DM), surgical time, blood transfusion requirements, soft tissue thickness, and mortality rates. MATERIAL AND METHODS This retrospective study included 49 patients who underwent RHA between 2015 and 2020. Patients were divided into aseptic (n=34) and septic (n=15) groups. Demographic characteristics, comorbidities, preoperative erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels, soft tissue thickness, and revision surgery time were compared. RESULTS ESR and CRP levels were significantly higher in the septic group (p=0.002, p=0.001), soft tissue thickness was lower (p=0.003), blood transfusion requirements (p<0.001) and surgical times (p<0.00001) were higher, while no significant difference was found in mortality rates between the groups (p=0.576). CONCLUSIONS This study examined septic and aseptic loosening in revision hip arthroplasty, finding higher inflammatory markers, increased transfusion needs, longer operative times, and greater infection risk with diabetes in septic cases. In our study, soft tissue thickness was found to be lower in infected cases, unlike the literature. While previous studies suggested that soft tissue thickness was the cause of infection, our study indicates that the decrease in skin thickness is a consequence of infection.
