Purpose: To present the results of arthroscopic treatment of acute septic arthritis of the hip joint in children aged 10 years or younger. Methods: Patients with a minimum follow-up period of 2 years who underwent arthroscopic treatment (anterolateral and medial subadductor 2-portal approach) of acute septic arthritis of the hip joint between January 2014 and January 2017 were included in this retrospective case-series study. The exclusion criteria included fungal infection, late presentation (≥5 days after the onset of the symptoms), presence of concomitant osteomyelitis, osseous pathologic conditions on radiography suggesting osteomyelitis, immunocompromised condition, history of surgery or infection surgery from the affected extremity, immobility owing to neuromuscular pathologic conditions, and identification of inflammatory or reactive arthritis during follow-up. The diagnosis of septic arthritis was confirmed according to the Waldvogel criteria. Clinical outcomes were assessed according to the Bennett score and Harris Hip Score. Results: We evaluated 15 hips in 15 patients (6 female and 9 male patients) with a mean age of 5.2 years (range, 2-10 years) in this study. The mean hospital stay was 4.2 days (range, 3-7 days), and the mean antibiotic-use period was 34 days (range, 26-45 days). The most causative pathogen was Staphylococcus aureus (40%) (including methicillin-sensitive S aureus) and was isolated and cultured in all patients. All patients had full range of motion of the hip joint. All of the Bennett scores were excellent; the mean Harris Hip Score was 96.3 (range, 92.5-100) after a minimum follow-up period of 24 months (mean, 26.1 ± 3.2 months; range, 24-35 months). No patient needed additional surgical intervention. No degenerative changes or avascular necrosis developed. Conclusions: According to our results, arthroscopic treatment is an effective choice for the treatment of acute septic arthritis of the hip joint in children aged 10 years or younger. Level of Evidence: Level IV, retrospective case series.

Purpose To determine the clinical and radiographic efficacy of hyaluronic acid–based cell-free scaffold applied in combination with microfracture versus microfracture alone in patients with focal osteochondral lesion of the knee joint. Methods Clinical data of 43 patients between 24 and 55 years of age were evaluated. Hyaluronic acid–based cell-free scaffold was applied in combination with microfracture for 19 knees (group 1), whereas microfracture alone was the surgical intervention for 24 knees (group 2). All lesions were Outerbridge grade III or IV with a mean size of 3.6 ± 1.3 cm2. The mean follow-up time was 25.7 months. Visual analog scale (VAS), Lysholm knee score, and Tegner activity scale were the instruments used to evaluate the clinical status. Magnetic resonance observation of cartilage repair tissue (MOCART) system was used to analyze the characteristics of repair tissue. Results Better VAS and Lysholm scores were detected in group 1 at 12 and 24 months (P =.019 and P =.025). According to the Tegner activity scale, group 1 had also better activity level at the end of 24 months after surgery (P =.020). The mean time from surgery to return to nonimpact sports activities was 7.8 months in group 1, whereas it was 9.2 months in group 2 (P =.013). Complete repair with the filling of the defect was achieved in 7 (36.8%) of the knees in group 1, whereas it was 4 (16.6%) of the knees in group 2 according to the MOCART system at 24 months. Conclusions Single-stage regenerative cartilage surgery using hyaluronic acid–based cell-free scaffold in combination with microfracture for focal osteochondral lesions of the knee revealed promising clinical outcomes at 24 months of follow-up, but the clinical significance of the differences seen is simply not known. Level of Evidence Level III, retrospective comparative study.

Purpose To describe a modified technique for arthroscopic-assisted transfer of the latissimus dorsi tendon in a selected group of patients with irreparable rotator cuff tears and pseudoparalysis and to evaluate its short-term results. Methods Fifteen patients with irreparable rotator cuff tears and pseudoparalysis treated by arthroscopic-assisted latissimus dorsi tendon transfer were included. The mean patient age was 61.53 ± 6.24 years (range, 52-71 years). Patients were assessed with physical examination, University of California Los Angeles (UCLA) Score and Constant-Murley score, as well as visual analog scale score at a mean follow-up of 26.4 ± 2.58 months (range, 24-31 months). Results At final follow-up, mean UCLA score increased to 27.47 ± 6.31 compared with the preoperative UCLA score of 6.53 ± 2.1 (P <.001). Constant-Murley score was 21 ± 7.41 and 59.73 ± 13.62 (P <.001), visual analog scale pain score was 7.47 ± 1.06 and 2.47 ± 0.91 (P <.001), active forward flexion was 58° ± 21.11° and 130° ± 30.05° (P <.001), active abduction was 51° ± 21.64° and 129.67° ± 25.45° (P <.001), and active external rotation was 13.33° ± 21.68° and 32° ± 18.03° (P <.001) preoperatively and postoperatively, respectively. Mean acromiohumeral distance was 3.13 ± 1.40 mm preoperatively, whereas it was 5.67 ± 1.67 mm postoperatively (P <.001). No significant complications requiring a revision surgery was observed during the final follow-up. Conclusions The modified technique of arthroscopic-assisted transfer of the latissimus dorsi tendon is a feasible, minimally invasive option for the surgical treatment of irreparable rotator cuff tears in a subset of patients with pseudoparalysis.

Purpose To investigate the effects of the subscapularis tendon slip number (STSN) and coracoid morphology by magnetic resonance imaging in patients with and without subscapularis tears. Methods Patients who underwent shoulder arthroscopy between February 2004 and June 2015 were re-evaluated. Those with a subscapularis tear (study group) and those with other pathologies (control group) were compared with each other. Magnetic resonance imaging scans and surgery videos of the patients were reassessed. Transverse and sagittal coracohumeral distance (CHD), coracoid overlap (CO), coraco-coracoid base angle (CBA), coracoglenoid distance (CGD), and STSN were measured. Results The study and control groups comprised 141 and 78 patients, respectively. The mean age was 57.01 ± 10.95 (similar in both the groups). The mean transverse CHD and sagittal CHD were not different between the groups and also between female and male patients. For the study and control groups, the mean CBA and CGD values were also similar. The mean CO was 24.01 ± 4.9 and 21.29 ± 4.58 for the study and control groups, respectively (P < .001). With the receiver operating characteristic curve of the CO, the sensitivity was 62% and the specificity was 64% at the cutoff value of 22.85 mm. The STSN was in the range between 1 and 6; the STSN was 3 or less in 61.5% of the study group and in 38.5% of the control group (P = .005). Conclusions The CO was the most valuable parameter predicting any potential subcoracoid impingement, and the STSN was inversely correlated with subscapularis tears. However, in predicting a potential subcoracoid impingement, the CHD measurements were not significant, as well the CGD and CBA. Level of Evidence Level III, retrospective comparative study.

Purpose To determine predictors of the clinical outcome after arthroscopic partial meniscectomy performed for acute trauma-related medial meniscal tear leading to mechanical symptoms in patients more than 60 years of age. Methods In this retrospective study with 4.1 years' follow-up, the clinical data of 154 arthroscopic partial medial meniscectomies were evaluated. The body mass index (BMI), duration of symptoms, the hip-knee-ankle angle, type of the meniscal tear, presence of any chondral lesions, degenerative changes in the patellofemoral joint, the status of the cruciate ligaments and lateral meniscus, and the presence of any plica or synovitis were the independent variables. Visual Analog Scale (VAS) and Lysholm Knee Scoring Scale were the instruments used as outcome measures. Multivariate analysis was performed to determine the major predictors. Results The mean VAS score for 154 knees evaluated in this study improved from 5.6 points preoperatively to 2.3 points at the latest follow-up. The mean Lysholm score improved from 43 points to 72.7 points. VAS and Lysholm scores at the latest follow-up were significantly worse in patients with a preoperative BMI ≥ 26 kg/m2, hip-knee-ankle angle > 5°, grade III or IV chondral lesion of the medial compartment according to Outerbridge classification, degenerative changes in patellofemoral joint surfaces, and an anterior cruciate ligament that was either partially ruptured or degenerative with increased laxity. Conclusions A preoperative BMI ≥ 26 kg/m2, Outerbridge grade III or IV chondral lesion of the medial compartment of the operated knee joint diagnosed during arthroscopic intervention, degenerative changes in patellofemoral joint surfaces, and the presence of an anterior cruciate ligament either partially ruptured or degenerative with increased laxity should be considered as the major predictors of the clinical outcome after arthroscopic partial meniscectomy performed for acute trauma-related symptomatic medial meniscal tear in patients more than 60 years of age.
