The comparison between standard blasted and hydroxyapatite (HA)-coated cementless femoral stems (CLS stem) was made in the same patients who have bilateral late-stage osteonecrosis. Clinical and radiographic evaluations were performed in 20 patients (among 29 patients) with the minimum follow-up of 10 years (range, 123-168 months). Endosteal bone formation(More)
This study was undertaken to analyze the clinical and radiologic results of acetabular revision arthroplasty using an impacted morselized allograft and a cementless cup and was performed on 71 hips of 62 patients who were followed up for a minimum of 10 years (10 years to 14 years 8 months; mean, 12 years). The acetabular bone defects were classified using(More)
PURPOSE Femoral intertrochanteric fractures are common in the elderly. Appropriate surgical fixation of trochanteric fracture fragments can restore normal anatomical structure and ambulation, and can aid in the recovery of biomechanical function of the hip. We evaluated clinical outcomes of bipolar hemiarthroplasty using a wiring technique for trochanteric(More)
Human adipose-derived stem cells (hASCs) have a capacity to undergo adipogenic, chondrogenic, and osteogenic differentiation. Recently, hASCs were applied to various fields including cell therapy for tissue regeneration. However, it is hard to predict the direction of differentiation of hASCs in real-time. Matrix metalloproteinases (MMPs) are one family of(More)
Joints deformed or injured by trauma, different forms of arthritis, infection and other causes tend to aggravate rather than regenerate. These progressive joint abnormalities may lead to severe pain, claudication, and nonfunctional ambulatory status, and tend to manifest more evidently in the hip joint than in the knee or ankle joints.
