No. 004: January-February 2020

This month, we are honored to feature an interview with Dr. André Ferreira, orthopedic surgeon and successor to Gérard Gacon at the Clinique du Parc in Lyon. Trained within the Lyon school of arthroplasty, Dr. Ferreira has developed a career defined by consistent engagement with the technical evolution of hip and knee replacement. A proponent of double mobility and cementless fixation, he has extended his influence internationally through his role in organizing the Lyon Hip Arthroplasty congress, fostering public-private partnerships at a global level.

The scientific articles in this issue address several interconnected dimensions of hip surgery and implant technology. The mechanics and clinical implications of acetabular reaming are examined alongside radiological modes of fixation of a tapered, wedged proximally coated femoral stem, providing surgeons with both technical and evaluative perspectives on primary arthroplasty. Complementing these, a study on weight limits associated with commonly used femoral stems for total hip arthroplasty addresses critical patient safety considerations in implant selection. The integration of digital technology is explored through an analysis of robotic-assisted total hip arthroplasty: from planning to robotization, while contributions in shoulder surgery examine innovations in AC-joint reconstruction using low-profile implants.
