    At what point during total knee arthroplasty operations are gloves most frequently torn?
    (SAGE Publications Ltd, 2020) Karakus, Ozgun; Sarı, Ahmet Sinan
    Purpose: The aim of this study was to determine the time points during a total knee arthroplasty operation when there is the greatest possibility of tearing a surgical glove and thus the stage of the operation at which there is the greatest risk of infection. Methods: The study included 300 total knee arthroplasty cases performed by 10 orthopedic surgeons. Using a chronometer during the operation, the upper layer of each surgical glove was removed and inflated with sterile saline at 10-min intervals. When a tear was determined, a record was made of the time it occurred, the stage of the operation, the finger that was torn, and the side (right or left hand). Results: The mean time of the glove perforation was 40.74 ± 10.69 min. Glove tears occurred at the rate of 28.9% (n = 39) in the thumb, 63.7% (n = 86) in the index finger, 2.2% (n = 3) in the middle finger, and 5.2% (n = 7) in the ring finger. The tears occurred after the femoral cut in 8.1% (n = 11), after the tibial cut in 14.8% (n = 20), at the stage of trial component reduction in 52.6% of cases (n = 71), after placement of the prosthesis in 7.4% (n = 10), and at the closure stage in 17% (n = 23) (p < 0.001). Conclusion: The fingers requiring the most care during total knee arthroplasty are the thumb and index finger. The stages of the operation with the greatest risk for glove tears are trial component reduction and wound closure. Changing gloves after these high-risk surgical stages would help to decrease the risk of periprosthetic infections. Level of Evidence: Level IV/Case series © The Author(s) 2020.

    Comparison of olecranon fixation techniques following transolecranon approach in intra-articular fractures of distal humerus in adult patients
    (SAGE Publications Inc., 2020) Ocalan, Halil Ibrahim; Karakus, Ozgun; Karakurum, Gunhan
    Background: In this study, we assessed functional outcomes among olecranon fixation techniques used following transolecranon approach in patients with comminuted fracture of distal humerus. Methods: The study included 37 elbows that underwent olecranon osteotomy due to distal humerus fracture. Functional outcomes were assessed among patients who underwent fixation via tension band technique, plate, or screw fixation. Results: The implant irritation was seen in 18% of patients who underwent K-wire plus tension band fixation, in 75% of patients who underwent olecranon plate plus screw fixation, and in 18% of patients who underwent cancellous screw fixation. The rate for implant removal was 2.6 folds lower in K-wire plus tension band fixation when compared to olecranon plate plus screw fixation. Conclusion: We concluded that K-wire plus tension band technique and cancellous screw fixation performed in accordance with technical principles caused less skin problem when compared to other techniques. In olecranon fixation, both methods with enhanced stability by tension band can be preferred. © The Author(s) 2019.

    Difference in the results of repair made with single or double rows according to the shape and size of the tear in arthroscopic rotator cuff surgery
    (Lippincott Williams and Wilkins, 2021) Karakus, Ozgun; Karaman, Ozgur; Sari, Ahmet Sinan; Saygi, Baransel
    The aim of this study was to evaluate the effect on the results of patients applied with arthroscopic full layer total layer rotator cuff repair made according to the shape and size of the tear.The study included a total of 120 patients applied with arthroscopic full layer rotator cuff repair as single or double row repair. The patients were separated into 3 groups of 40 according to the shape of the tear, as Group A (crescent type), Group B (U type), and Group C (L type).The mean age of the whole sample was 66.68 ± 6.86 years (range, 50-81 years). A statistically significant difference was determined between the groups in respect of constant murley (CM), American shoulder and elbow surgeons score (ASES), and University of California Los Angeles score (UCLA) scores (P < .05). The scores of Group A of all the scales were found to be higher than those of Group C (P < .05). In single row and double row repair of small and medium-sized tears of all shapes, no significant difference was determined in respect of the CM and UCLA scores (P > .05).No significant difference was determined between single and double row repair of crescent type tears of all sizes. In large U-shaped tears, the CM, ASES, and UCLA scores were determined to be high in double row repair. © 2021 the Author(s). Published by Wolters Kluwer Health, Inc.

    Is experience alone sufficient to diagnose developmental dysplasia of the hip without the bony roof (alpha angle) and the cartilage roof (beta angle) measurements? A diagnostic accuracy study
    (Lippincott Williams & Wilkins, 2020) Sari, Ahmet Sinan; Karakus, Ozgun
    In the Graf method of hip ultrasonography, the diagnosis of the infantile hip with developmental dysplasia of the hip (DDH) is strictly dependent on the bony roof (alpha angle) and the cartilage roof (beta angle) measurements. In this study, we investigated whether the infant hip could be diagnosed with DDH solely by evaluating ultrasound images obtained in the standard plane, without bony roof and cartilage roof measurements, in respect to different professional experience levels. Two hundred ten hip ultrasounds were randomly selected from patients who presented to our hospital for DDH screening. A total of 6 ultrasound images were obtained for each hip. The hip morphology evaluations were made without the bony roof and the cartilage roof measurements by 2 orthopedic surgery residents; 2 orthopedic surgery specialists, trained in the diagnosis and the treatment of the DDH; and 2 pediatric orthopedic surgery professors, highly experienced in the diagnosis and treatment of DDH. After hip morphology evaluations, the bony roof and the cartilage roof measurements were obtained and hip type evaluations were made by the same raters, according to the Graf method of hip ultrasonography. The highest intraobserver agreements between the hip maturity evaluation before and the hip type evaluation after measurements were .676 (P < .001) and .577 (P < .001) in professors 2 and 1, respectively, and the lowest agreements were .185 (P < .01) and .289 (P < .001) in specialist 1 and resident 2, respectively. The diagnosis of the infant hip as DDH could not be made solely by evaluation of the ultrasound images obtained in the standard plane without the bony roof and the cartilage roof measurements. The bony roof and the cartilage roof measurements were obligatory for the diagnosis of the infant hip as DDH, even in the very experienced pediatric orthopedic surgeons. Level of evidence: 2.

    Is it difficult to obtain inter-observer agreement in the measurement of the beta angle in ultrasound evaluation of the paediatric hip?
    (BioMed Central Ltd., 2019) Karakus, Ozgun; Karaman, Ozgur; Sari, Ahmet Sinan; Orak, Mehmet Mufit; Muratli, Hasan Hilmi
    Introduction: The aim of this study was to determine the differences and consistencies in the morphological and angular interpretations of standard USG images. Therefore, it was aimed to show the correlations of orthopaedic doctors with different periods of experience in hip ultrasound measurements taken with the Graf method. Materials and methods: The study included 210 infants randomly selected from those who presented at our hospital for DDH screening. A total of 6 ultrasound images were taken for each hip. These images were evaluated by two paediatric orthopaedic professors, two orthopaedic specialists and two orthopaedic residents. The correlations of these measurements between all the doctors were evaluated statistically. Results: In beta angle evaluation, agreement between all the evaluators was at the level of 0.054. No agreement was seen between the two residents or between the two specialists (p = 0.003, p = 0.998, p = 0.998, respectively). Agreement between the two professors was determined at the level of 0.508 (p < 0.001). Agreement was determined at the level of 0.066 between the specialists and the residents. No agreement was observed between the specialists and the professors or between the professors and the residents (p = 0.014, p = 0.098, p = 0.737, respectively). Conclusions: It can be concluded that greater emphasis on the beta angle, the cartilage labrum, and more detailed explanations of this subject in the resident training program will achieve standardisation on this subject, and this is in direct proportion to clinical experience.
