Migration pattern of a cobalt-chrome monoblock acetabular component after metal-on-metal hip resurfacing.

Objectives: The purpose of this study was to study the initial fixation and migration pattern of a monoblock acetabular component used for a metal on metal hip resurfacing using Einzel Bild Roentgen Analyse (EBRA).

Methods: 99 patients with a mean age of 49.6 years (range 28.

The knee adduction moment during gait is associated with the adduction angle measured during computer-assisted total knee arthroplasty.

Computer-assisted surgery can be used to measure 3-dimensional knee function during arthroplasty surgery; however, it is unknown if the movement of the knee measured during surgery is related to the in vitro, dynamic state of the knee joint, specifically the knee adduction moment during gait, which has been related to implant migration. The purpose of this study was to determine if the preoperative adduction moment is correlated with the knee abduction/adduction angle measured intraoperatively. A statistically significant correlation was found between the mean (r(2) = 0.
