    Background/Objectives: Different patient-reported outcomes and radiological results are reported depending on whether microfracture, drilling, or nanofracture is utilized in the arthroscopic treatment of talus osteochondral lesions, but the first-line treatment is still controversial. The aim of this study is to evaluate the early patient-reported outcomes of microfracture, nanofracture, and antegrade drilling methods in talus anteromedial osteochondral lesions. Methods: A total of 77 patients who presented with ankle pain between October 2016 and June 2022, were diagnosed with talus osteochondral lesions, and underwent microfracture (n: 27), nanofracture (n: 25), and K-wire drilling (n: 25) were included. Demographic data of the patients were evaluated, such as age, gender, lesion side, dominant extremity, body mass index (BMI), smoking status, smoking (pack/day-year), and symptom duration. Patient-reported outcomes of the patients were evaluated with VAS (visual analog scale) and AOFAS (American Orthopedic Foot & Ankle Society) scores measured before surgery and at 6 and 12 months after surgery. The results were evaluated at the significance level of p < 0.05. Results: There were no statistically significant differences among the microfracture, nanofracture, and drilling groups in terms of age, gender, lesion side, dominant extremity, BMI, smoking, or daily cigarette use (p = 0.121, p = 0.852, p = 0.956, p = 0.731, p = 0.881, p = 0.769, p = 0.124). Similarly, the mean duration of symptoms did not differ significantly between the groups (p = 0.336). Although AOFAS and VAS scores significantly improved in all groups (p = 0.0001), there were no statistically significant differences between the microfracture, nanofracture, and drilling groups at preoperative, 6th-, and 12th-month measuring points. The microfracture group showed a significantly higher AOFAS improvement from preop to 6 months compared to the other groups (p = 0.012), though no differences were found between nanofracture and drilling or in 12-month changes. VAS percentage changes showed no significant differences among groups at either time point. Conclusions: All treatment groups had similar baseline characteristics and outcomes, with the microfracture group showing a greater functional improvement at 6 months.

    Objectives: In this study, we aimed to investigate the morphological and histological effects of tranexamic acid (TA) on wound healing in a rat wound model.Materials and methods: A total of 24 adult mal e Wistar Albino rats were used in this study. All rats were simple randomly divided into three groups including eight rats in each group. A full-thickness skin defect was created on the back of the rats in all groups. Serum physiological (2 mL) was instilled saline drops after wound formation (control group). Wound was created and topical TA (0.12 to 0.15 mL [30 mg/kg]) was applied (local group). Intravenous TA (0.12 to 0.15 mL [30 mg/kg]) was applied intravenously before the wound was created (intravenous group). The wound diameters of the groups were photographed and measured on Days 0, 3, 7, 10, 14 and, at the end of Day 14, the rats were sacrificed and their histopathological results and wound diameters were compared.Results: Fibroblast count values of the control group were found to be significantly lower than the local group (p=0.002), and no significant difference was observed between the local and intravenous groups (p>0.05). The collagen density (%) values of the control group were found to be significantly higher than the local and intravenous groups (p=0.016 and p=0.044). Wound diameter values of the control group on Day 10 day were found to be significantly higher than the local and intravenous groups (p=0.001). In addition, the wound diameter values of the control group on Day 14 were found to be significantly higher than the local and intravenous groups (p=0.001 and p=0.0001). The wound diameter changes of the control group on Days 0-10 were found to be significantly lower than the local and intravenous groups (p=0.001). In addition, the wound diameter changes of the control group on Days 0-14 were found to be lower than those of the local and intravenous groups (p=0.001 and p=0.0001).Conclusion: The use of local or intravenous TA may have positive effects on the fibroblast count and wound contraction in a rat wound model.
