BACKGROUND The quadriceps femoris may be a reliable reference to proper alignment in total knee arthroplasty (TKA). We previously showed the quadriceps vector (QV) to be the most parallel to the spherical axis (SA-center hip to center medial condyle)

Modular neck components in total hip arthroplasty enhance intraoperative flexibility and ease of revision. Femoral modular components allow alteration of neck length, version, and offset once the femoral stem has been implanted, leading to purported

The use of femoral stems with dual-taper modularity in total hip arthroplasty offers increased flexibility in restoring hip-center anatomy. Independent of femoral fixation, the modular neck offers the surgeon additional options in recreating femoral

The functional flexion axis (FFA) is the principal axis around which the knee moves and thus, by definition, does not move in vertical displacement relative to the tibia. The transepicondylar axis (TEA) has been reported to coincide with the FFA. If

Modular femoral neck use in total hip arthroplasty (THA) affords the operating surgeon increased intra-operative flexibility with regard to offset, version, and leg length. Proponents also advocate a reduced dislocation rate, reduced impingement issu

There continues to be controversy about the kinematics of the human knee. This study used seven knees from cadavers moved by pulling on the quadriceps tendon in an open chain fashion using video motion analysis to determine the instantaneous helical

It is common to assert that restoration of normal knee kinematics is essential for the best functional result after knee arthroplasty. Previous studies using the progression of the geometric centre axis have suggested that kinematics after unicompart

The quadriceps is the primary extensor of the knee. Its vector, which is perpendicular to the flexion axis of the knee, is important in understanding knee function and properly aligning total knee components. Three-dimensional (3-D) imaging enables e

Use of gentamicin-impregnated methylmethacrylate beads is a relatively new and effective method of treating osteomyelitis. Although previous studies have concluded that such therapy is associated with low systemic toxicity, no data are available rela
