In order to permit soft tissue balance under more physiological conditions during total knee arthroplasties (TKAs), an offset-type tensor was developed to obtain soft tissue balancing throughout the range of motion with reduced patello-femoral (PF) and aligned tibiofemoral joints. The main purpose of the present study was to assess intra-operative soft(More)
The purpose of this study was to prove the hypothesis that soft tissues are well balanced using the gap technique with a navigation system in cruciate-retaining (CR) and posterior-stabilised (PS) total knee arthroplasty (TKA), leading to better clinical outcomes compared with the measured-resection technique. One hundred and thirty-five TKAs (90 CR and 45(More)
The purpose of this study was to test the hypothesis that intraoperative soft-tissue balance assessed by an offset-type tensor influences post-operative knee kinematics after cruciate-retaining (CR) total knee arthroplasty (TKA). The influence of intraoperative soft-tissue balance on knee kinematics in CR-TKA was retrospectively analysed in 30 patients.(More)
CXC chemokine receptor 4 (CXCR4) is a specific receptor for stromal-derived-factor 1 (SDF-1). SDF-1/CXCR4 interaction is reported to play an important role in vascular development. On the other hand, the therapeutic potential of endothelial progenitor cells (EPCs) in fracture healing has been demonstrated with mechanistic insight of(More)
Recent reports indicated that human isolated CD271+ bone marrow mesenchymal stromal cells (BM-MSCs) have a greater expansion and potential for multipotent differentiation including chondrogenesis than classical plastic adherent (PA) BM-MSCs in vitro. Therefore, we set up a hypothesis that CD271+ MSCs may have a greater chondrogenic potential than PA-MSCs in(More)
PURPOSE The use of musculoskeletal bioengineering and regenerative medicine applications in orthopaedic surgery has continued to evolve. The aim of this systematic review was to address tissue-engineering strategies for knee ligament reconstruction. METHODS A systematic review of PubMed/Medline using the terms "knee AND ligament" AND "tissue engineering"(More)
The purpose of this study was to investigate kinematic factors affecting postoperative knee flexion after cruciate-retaining (CR) total knee arthroplasty (TKA) by analysing pre- and postoperative knee kinematics. We retrospectively analysed 58 patients with osteoarthritis who received the same implant series. Pre- and postoperative kinematics were measured(More)
The first purpose of this study was to examine whether fluoroscopic-based navigation system contributes to the accuracy and reproducibility of the bone tunnel placements in single-bundle anterior cruciate ligament (ACL) reconstruction. The second purpose was to investigate the application of the navigation system for double-bundle ACL reconstruction. A(More)
Although implantation of crude bone marrow cells has been applied in a small number of patients for fracture healing, transplantation of peripheral blood CD34(+) cells, the hematopoietic/endothelial progenitor cell-enriched population, in patients with fracture has never been reported. Here, we report the first case of tibial nonunion receiving autologous,(More)
BACKGROUND It has been recently reported that human anterior cruciate ligament (ACL) ruptured tissue contains abundant vascular stem cells that contribute to tendon-bone healing in an immunodeficient rat model of ACL reconstruction. HYPOTHESIS Autologous ruptured ACL tissue has an effect on the maturation of bone-tendon integration in anterior cruciate(More)
