Background: The aim of this study was to compare the clinical and magnetic resonance imaging (MRI) outcomes of arthroscopic microfracture (MF) plus chitosan-glycerol phosphate/blood implant and MF alone for the treatment of the osteochondral lesions of the talus (OCLTs). Methods: Patients who underwent either MF plus chitosan (group 1, n = 32) or MF alone (group 2, n = 31) between 2015 and 2019 in 2 separate time periods were retrospectively analyzed. Visual analog scale (VAS) score and American Orthopaedic Foot & Ankle Society (AOFAS) score were used for clinical evaluation. The magnetic resonance observation of cartilage repair tissue (MOCART) system was used for MRI evaluation. The mean follow-up time was 32 ± 13 months (range, 12-61 months). Results: Postoperatively, we detected significant improvements in both groups in terms of VAS and AOFAS scores. However, we observed no statistically significant difference between groups in terms of clinical scores, except the mean VAS function score, which was significantly higher in group 1 ( P = .022). According to MOCART scale, complete repair with the filling of the chondral defect and intactness of the surface of the repair tissue were more common in group 1. However, these parameters did not significantly differ between groups ( P = .257 and .242, respectively). Conclusion: Arthroscopic MF plus chitosan glycerol phosphate/blood implant did not result in better clinical and MRI outcomes compared with MF alone in the treatment of OCLTs. Level of Evidence: Level III, retrospective comparative study.

This study aimed to comparatively evaluate the quality of life scores of patients with pediatric flexible flatfoot (PFF) according to the use of foot orthoses. We also aimed to compare quality of life scores of children and their parents. Nonobese children aged between 5 and 10 years old who were diagnosed as PFF according to physical and radiological examinations were included in this cross-sectional comparative study. All children and their parents completed the Turkish translation of Oxford ankle foot questionnaire (OxAFQ) which contains four domains (physical, school and play, emotional, and footwear). Patients were grouped according to the use of foot orthoses (group I: no foot orthoses group and group II: foot orthoses group). Comparison of OxAFQ scores demonstrated no significant differences between the two groups. However, the mean emotional scores of parents were significantly lower in group II (P = 0.007). In group I, the mean emotional score of children was significantly lower compared to their parents’ scores (P = 0.001). In group II, the mean physical score of children was significantly lower compared to their parents’ scores (P = 0.003). According to our results, we observed no significant difference in terms of quality of life scores between children using foot orthoses and not using foot orthoses. However, we observed significantly lower emotional scores in parents whose children were using foot orthoses. We recommend that physicians should be aware of low physical scores in children with PFF and should inform parents about this situation rather than considering foot orthoses to relieve parents’ concern about foot deformity.

Background and Objectives: This study aimed to examine the ventricular repolarization (VR) disturbances of patients operated on for acute spontaneous Achilles tendon ruptures (ATRs), by comparing them with a healthy individual control group. Materials and Methods: Between June 2014 and July 2020, a total of 29 patients (28 males, 1 female; mean age: 40 ± 9.78 years; range, 21–66 years) who presented to the emergency department within the first three weeks of injury, and were diagnosed with acute spontaneous ATRs and treated with an open Krackow suture technique, were retrospectively analyzed. Fifty-two healthy individuals (47 males, 5 females; mean age: 39 ± 11.45 years; range, 21–66 years) were recruited as a control group from the cardiology outpatient clinic. Clinical data (demographic features and laboratory parameters (serum glucose, creatinine, hemoglobin, white blood cell count, and lipid profile)) and electrocardiograms (ECGs) were collected from medical records. ECGs were evaluated for heart rate and VR parameters of QRS width, QTc interval, cQTd interval, Tp-e interval, and Tp-e/QT ratio. The clinical data and these ECG parameters were compared between groups. Results: There was no statistically significant difference between groups, regarding clinical data (all p < 0.05). Among ECG parameters, heart rate, QRS width, QTc interval, and cQTd interval were similar between groups (all p < 0.05). There were two important statistically significant findings of this research: The mean Tp-e interval was longer (ATR group: 72.4 ± 24.7, control group: 58.8 ± 14.5, p: 0.01), and the Tp-e/QT ratio was higher (ATR group: 0.2 ± 0.1, control group: 0.16 ± 0.4, p: 0.027) in the ATR group. Conclusions: According to the ventricular repolarization disturbances found in this study, patients with ATR may be at a higher risk of ventricular arrhythmia than healthy people. As a result, ATR patients should be assessed for ventricular arrhythmia risk by an expert cardiologist.

Objective: We aimed to share our radiological and clinical results with a mid-term follow-up on patella fractures treated with tension band wiring (TBW). Methods: Patients surgically treated with TBW for AO type 34-A1/C1/C2/C3 patella fractures between January 2013 and June 2021 at a level 1 trauma center were included. For radiological evaluation, radiographs obtained at the routine follow-up were analyzed for complications (such as nonunion, malunion, loss of reduction, malreduction, patella baja, elongated patella, implant failure), Insall-Salvati Index (ISI), and Patellar Morphology Ratio (PMR). The Knee Injury and Osteoarthritis Score (KOOS) was utilized for functional evaluation, which includes five subscales: pain, symptoms, activities of daily living (ADL), sports/recreation, and quality of life (QOL). The clinical assessment also included the range of motion (ROM), thigh circumference (TC), and complications such as implant irritation (II). Results: This study reviewed 42 eligible patients (10 females, 32 males) with a mean age of 42.6 ± 16.1 years and a mean follow-up of 35.4 ± 24.1 months. There were 28 patients (66.7%) with at least one complication (II: 66.7%, flexion deficit: 61.9%, malunion: 40.5%, elongated patella/patella baja: 16.7%). The reoperation rate was high at 69.1% due to the high implant removal rate for II. There were statistically significant differences between injured (I) and uninjured contralateral healthy knees (UI) in terms of mean KOOS subscale scores (symptoms: I: 72.3, UI: 89.8; pain: I: 70.4, UI: 89.4; ADL : I: 72.1, UI: 90; sports: I: 61.4, UI: 84.8; QOL: I: 67.9, UI: 86.2), mean flexion degrees (I: 126.2°, UI: 135.4°), mean ISI (I: 0.9, UI: 1.0), and mean PMR (I: 1.5, UI: 1.4) (all p < 0.01). There was no difference in mean extension degrees and TC (all p > 0.05). All fractures achieved union. Conclusion: Firstly, the mid-term clinical results of patellar fractures treated with TBW were significantly worse than the contralateral healthy knee; secondly, implant irritation, knee flexion deficit, malunion, and patella baja were the significant complications, and efforts should be made to manage these problems; thirdly, patellar fractures are susceptible to developing interesting cases of the elongated patella.
