OBJECTIVES Trigger finger is frequently treated with tendon sheath injections. This cadaveric study evaluated the accuracy and safety of blind and sonographically guided tendon sheath injections. To our knowledge, a study that precisely mapped the locations of material injected into the tendon sheath has not been reported previously. METHODS A total of 40(More)
OBJECTIVE The objective of our study was to investigate the clinical feasibility of ultrasound elastography for assessing patients with lateral epicondylosis and to establish an objective and quantitative method of elastographic measurement in the affected tendon. SUBJECTS AND METHODS A total of 97 symptomatic and 89 asymptomatic common extensor tendons(More)
The atypical presentation of intra-articular osteoid osteoma in the hip joint frequently results in delayed diagnosis compared with the diagnosis of extra-articular osteoid osteoma. We present 2 cases of hip joint osteoid osteoma in children treated by hip arthroscopy. Intra-articular osteoid osteoma was suspected when computed tomography (CT) findings were(More)
This study was conducted to test the hypothesis that growth factors can reduce the suppressive effect of titanium particles on MSCs. Cultured human MSCs at passage 3 were challenged with prepared cpTi particles at a concentration of 500 particles/cell along with one of the following growth factors: TGF-beta(1) (10 ng/mL), FGF-2 (10 ng/mL), IGF-I (100(More)
BACKGROUND The transtibial technique for posterior cruciate ligament reconstructions can potentially lead to poor clinical outcomes due to the "killer turn" effect. HYPOTHESIS Preserving the original posterior cruciate ligament fibers in the reconstruction will contribute significantly to the posterior stability of the knee joint, healing of the graft,(More)
The purpose of the present study was to test the potential of an MSC (mesenchymal stem cell)/PDO/PVA [polydioxanone/poly(vinyl alcohol)] hybrid scaffold construct to repair cartilage defects. For the in vitro study, MSCs were isolated from human bone marrow and cultured in PDO/PVA scaffolds for 4 weeks. Gross and microscopic examinations were performed, as(More)
BACKGROUND The purpose of this study was to report the clinical and radiological outcomes and surgical strategy for terrible triad injury of the elbow. We hypothesized that the outcomes of this type of injury would be satisfactory if the medial structure was routinely restored at the same time as the repair of the lateral structure. METHODS We(More)
To determine the relationship between clinical impairment and MRI findings in patients with adhesive capsulitis. Contrast-enhanced MRI of 97 patients with a clinical diagnosis of adhesive capsulitis (AC) were retrospectively reviewed. Specific MRI criteria, including thickness and gadolinium enhancement of the joint capsule in the axillary recess and(More)
BACKGROUND Detection of a posteroinferior labral lesion by physical examination is often difficult. PURPOSE To introduce a novel diagnostic test for detecting a posteroinferior labral lesion of the shoulder. HYPOTHESIS The Kim test can detect a posteroinferior labral lesion of the shoulder. STUDY DESIGN Cohort study (diagnosis); Level of evidence, 1.(More)
PURPOSE To validate the glenoid track concept in a cadaveric bipolar bone loss model and to test whether "on-track" and "off-track" lesions can be stabilized with Bankart repair (BR) with or without Hill-Sachs remplissage (HSR). METHODS Eight fresh-frozen cadaveric shoulders were tested in a custom apparatus with passive axial rotation and then(More)
