Dr. Shahan Yacoubian named in Los Angeles magazine as Super Doctors Rising Star

Dr. Shahan Yacoubian at Orthopaedic Surgery Specialists is listed in the Southern California’s Super Doctors Rising Stars Edition 2013, which is published in the August 2013 Los Angeles magazine (page S-11).  This honor ranks 2.5 percent of active Southern California physicians.

Selections for this honored list are made by the research team at Super Doctors, which is a service of Key Professional Media, Inc. Each year, the research team at Super Doctors goes through a thorough multi-phase selection process that includes a survey of doctors, an independent evaluation of candidates by the research staff, a peer review of candidates by practice area, and a good-standing and disciplinary check.

Dr. Shahan Yacoubian works on clinical orthopaedic trials

Dr. Shahan Yacoubian continues to remain on the forefront of hip and knee surgery. He is one of a few hip and knee surgeons participating in a multi-center evaluation of a newly modified knee replacement implant which uses Vitamin E in order to lengthen the life span of total knee replacements.

Knee replacements are commonly made up of 4 parts: A femoral component, a tibial component (both of which are typically made up of a metal alloy), a patella component, and a tibial polyethylene liner which is locked on to the tibial component. Both the tibial polyethylene liner and patella component are made of a plastic material which has historically been susceptible to wearing out over time. Recent advances in these materials now allows for Vitamin E (a powerful antioxidant) to be added to the plastic parts in order to improve their longevity.

As such, Dr. Shahan Yacoubian uses these implants in the total knee replacement surgeries he performs to provide patients with knee implants that will survive for the duration.
