The authors aimed to demonstrate the relationship between the sagittal mechanical axis of the tibia and other reference axes of the tibia and fibula in patients with advanced osteoarthritis of the knee joints, and then to identify a reliable landmark in order to minimize posterior tibial slope measurement errors. We evaluated 133 osteoarthritic knees with(More)
UNLABELLED The bone-patellar tendon-bone has been widely used and considered a good graft source. The quadriceps tendon was introduced as a substitute graft source for bone-patellar tendon-bone. We compared the clinical outcomes of anterior cruciate ligament reconstructions using central quadriceps tendon-patellar bone and bone-patellar tendon-bone(More)
BACKGROUND Platelet-rich plasma (PRP) has been recently used to enhance and accelerate the healing of musculoskeletal injuries and diseases, but evidence is still lacking, especially on its effects after rotator cuff repair. HYPOTHESIS Platelet-rich plasma accelerates recovery after arthroscopic rotator cuff repair in pain relief, functional outcome,(More)
Stem cells of fetal origin lie between embryonic and adult stem cells in terms of potentiality. Because of the ethical controversy surrounding embryonic stem cells and the relatively inferior quality of adult stem cells, the use of fetal stem cells would be an attractive option in future therapeutic applications. Here, we have investigated primitive(More)
The purpose of this study was to investigate the effect of adding multiple channeling of the greater tuberosity on the structural integrity of the repaired rotator cuff tendon. Fifty-six consecutive patients who underwent arthroscopic rotator cuff repair and postoperative computed tomography arthrography (CTA) were included in this study; 31 consecutive(More)
The purpose of this biomechanical study was to determine optimized configuration of additional half-hitches placed after various arthroscopic sliding knots. Four commonly used arthroscopic sliding knots, namely, the Duncan loop, the SMC, Weston, and SP knot, were included in this study. All knots were tied with a single-hole knot pusher using a knot-tying(More)
A randomized prospective study was undertaken to compare the accuracy of rotational alignment of the femoral component in total knee arthroplasty using a nonimage-based navigation system and a conventional method. The authors randomly used two methods and implants in 55 patients and measured the angles between posterior condylar lines and transepicondylar(More)
PURPOSE To identify the effects of using a Ti-Ni shape memory alloy ring shaped bone fixator (SMA-rBF) during the retrograde nailing of supracondylar femoral fractures. MATERIALS AND METHODS The authors reviewed 25 patients with a supracondylar femoral fracture treated by retrograde intramedullary nailing with or without SMA-rBF (group S, 12/25; group N,(More)
BACKGROUND Periprosthetic supracondylar fractures of the femur after total knee arthroplasty are not common but are usually difficult to treat due to the advanced age of patients and frequently accompanying osteoporosis. Retrograde intramedullary nailing can be effective in promoting healing of these fractures by providing sufficient stability, but the(More)
BACKGROUND The authors examined whether poor preoperative glucose control, as indicated by the hemoglobin A1c (HbA1c) level of more than 8%, is associated with postoperative wound and infectious complications in diabetic patients that have undergone total knee arthroplasty (TKA). METHODS One hundred and sixty-seven TKAs performed in 115 patients with type(More)
