    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 compared 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 in a cohort of 49 patients. Material/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 reports in the literature. While previous studies suggested that soft-tissue thickness was the cause of infection, our study indicates that the decrease in soft-tissue thickness is a consequence of infection.

    The Effects of Phenyramidol and Diclofenac Treatment on Fracture Healing in Rats
    (Korean Orthopaedic Assoc, 2024) Celik, Mucahit; Karaduman, Zekeriya Okan; Turhan, Yalcin; Arican, Mehmet; Gamsizkan, Mehmet; Saglam, Sonmez; Uludag, Veysel
    Background: Fracture healing or nonunion refers to a process in which many factors interact. In this study, we aimed to evaluate the radiological, histological, and biomechanical effects of phenyramidol and diclofenac, which are frequently used to treat post-fracture ture pain worldwide, on fracture healing and nonunion in a rat femur fracture model. Methods: In this study, 72 male Wistar-Albino rats aged 2-3 months and weighing 250 +/- 30 g were divided into 4 main groups. The rats were divided into 12 subgroups according to the early, middle, and late periods. A fracture model was created in rat femurs, and surgical fixation was performed. Postoperative analgesic treatment protocols included phenyramidol, diclofenac, phenyramidol + diclofenac, and the control group. The rats were sacrificed on the fifteenth, thirtieth, and forty-fifth days and were evaluated radiologically, histopathologically, and biomechanically. Results: Scoring was conducted independently by 2 orthopedists not involved in the study. When the results were analyzed statistically, no statistically significant difference was observed between the fifteenth and thirtieth day radiology score values of the control, diclofenac, phenyramidol, and Phenyramidol + diclofenac groups (p > 0.05), but there was a statistically significant difference (p < 0.05) between the forty-fifth day radiology score values of the control, diclofenac, phenyramidol, and phenyramidol + diclofenac groups. Conclusions: Our study shows that the use of diclofenac or phenyramidol alone negatively affects postoperative fracture healing. However, this effect was less pronounced in the combined treatment group. Histologic examination revealed that neither treatment had a significant effect on healing. There were statistical differences in biomechanical and radiologic properties between the phenyramidol and diclofenac groups; in particular, the diclofenac group had lower biomechanical properties.

    Significance of Preoperative Multidisciplinary Assessment with 30-Second Sit-to-Stand and Timed Up-and-Go Tests in Predicting Postoperative Outcomes
    (Mdpi, 2025) Yucel, Mucahid Osman; Saglam, Sonmez; Dalaslan, Rasit Emin; Arican, Mehmet; Karaduman, Zekeriya Okan; Akar, Bedrettin; Celik, Mucahit
    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.
