Determining the change in length of the anterolateral ligament during knee motion: A three-dimensional optoelectronic analysis.

Background: The variation of the anterolateral ligament (ALL) length during knee motion is still unclear, and the knee position in which a reconstruction graft should be tensioned remains controversial. The objective of this study was to determine the variation of the ALL length during knee motion using a three-dimensional optoelectronic system.

Methods: Kinematic analyses of 20 cadaveric knees were performed using a Motion Analysis® system.

Ten-Year Clinical and Radiological Outcomes of 100 Total Hip Arthroplasty Cases with a Modern Cementless Dual Mobility Cup.

Introduction: The original cementless Sunfit® dual mobility cup (SERF, Décines, France) exhibited limited osseointegration due to its hydroxyapatite and alumina coating. We hypothesized that replacement of the alumina with plasma-sprayed titanium + hydroxyapatite and improvement of the external geometry (Sunfit TH®) would not increase the risk of aseptic loosening. The primary goal of this study was to determine the survivorship and clinical and radiological outcomes among patients with the Sunfit TH® implant.
