BACKGROUND Osteoarthritis (OA) is now increasingly recognized as being related to the whole joint instead of the cartilage alone. In particular, the importance of subchondral bone in OA pathogenesis has drawn a lot of interest. The aim of this study is to investigate subchondral bone microstructural features in two femoral condyles of human knee osteoarthritis. METHODS Eighty subjects were en...

  Congenital dislocation of the knee (CDK) is a rare disorder. We report the case of a 7-year-old girl with bilateral knee stiffness, marked anterior bowing of both legs, and inability to walk without aid. Radiologic investigation revealed bilateral knee joint dislocation accompanied by severe anterior bowing of both tibia proximally and posterior bowing of both femur distally, demonstrating ...

Standard-length porous-coated tapered femoral stems perform exceedingly well in primary total hip arthroplasty (THA) at long-term follow-up. Nevertheless, there are multiple reasons to strongly consider the relatively new concept of short tapered stems. First, there is already a wide variation in the lengths of "standard" components and the ideal length is unknown. The goal of tapered stems is ...

J Bone Joint Surg [Br] 2004;86-B:1047-9. Received 4 March 2003; Accepted after revision 29 August 2003 Fractures and plastic deformities of the forearm are common in children. While axial deformities are easily recognised and treated, bowing of the radius may be overlooked. Physiological bowing is essential for full rotation of the forearm. We have used the method of Schemitsch and Richards to ...

Objectives Global sagittal spinal imbalance leads to compensatory pelvic retroversion and femoral flexion that is far from economical standing posture. Recent reports showed spinal instrumentation surgery provided remarkable restoration of spinal alignment and better health-related quality of life (HRQOL) by adult spinal deformity surgery. However, there is a few previous reports about the impa...

BACKGROUND Anatomic femoral tunnel placement for single-bundle anterior cruciate ligament (ACL) reconstruction is now well accepted. The ideal location for the tibial tunnel has not been studied extensively, although some biomechanical and clinical studies suggest that placement of the tibial tunnel in the anterior part of the ACL tibial attachment site may be desirable. However, the concern fo...

This article examines how the relationship between sagittal and coronal anatomy, anterior cruciate ligament (ACL) graft dimensions, and tibial and femoral tunnel placement affects the posterior cruciate ligament (PCL) and roof impingement, and their undesirable clinical consequences of motion loss and instability. Based on these interrelationships, a variety of checkpoints are defined that can ...

The current study used video clips of bowing actions depicted by three-dimensional computer graphics. The bend angle (15 degrees and 45 degrees) and duration of the bent posture (0-4.5 seconds) were varied. In the first experiment, the participants rated their subjective impressions of the bowing actions. The bowing actions that were made at a 45 degrees angle and held for more than 1 second we...
