“…Moreover, various factors such as the material shape and geometry, surface finish, and bearing surface affect the durability of a component, and the surgical approach used and the expertise of the surgeon may also affect its survivorship 18 . Other important factors that can influence the in vivo wear properties of the bearing surface are the shelf life and sterilization environment (air or an inert environment) of the polyethylene 19,20 . Regardless of these factors, the method of fixation of the acetabular component also affects survivorship of this component.…”

“…Calvert, et al reported more than 100% volumetric wear reduction of HXLP vs. conventional polyethylene in a randomized prospective study [3]. Long-term data reported by Engh et al showed the wear rate of conventional polyethylene to be 0.23 mm 3 /year as opposed to 0.04 mm 3 /year in HXLP [7]. The mechanical strength of a third-generation highly crosslinked polyethylene (X 3 , Stryker Orthopaedics, Mahwah, NJ) as measured by yield and ultimate fatigue has also been reported to be not significantly different from conventional polyethylene [6].…”

Background Total hip arthroplasty (THA) is one of the most successful surgical interventions devised in modern times. Attempts to change the current THA procedure with unproven innovations bring the risk of increased failure rates while trying to improve the benefit of the surgery. Questions/Purposes This manuscript examines the evolution of THA at the Rothman Institute illustrating the key elements that lead the success of this procedure at this institution. These key elements include femoral stem design, use of highly crossed-linked polyethylene and use of pain and rehabilitation protocols. We attempted to describe the long-term results regarding safety, effectiveness, and durability of specific THA implant designs used at this institution drawing on reported evidence in the literature. Methods The authors performed a review of peer-reviewed articles related to the Rothman Institute's experience with THA. Results Total hip arthroplasty is an efficient, safe, and durable procedure. It is a highly successful operation to restore function and improve pain. The survivorship of THA procedures at the Rothman Institute is higher than 99% at 10 years based on mechanical failure. The use of collarless, tapered wedge femoral stem, highly crossed-linked polyethylene, and improved pain rehabilitation protocols have contributed to this success. Conclusions There is a well-documented long-term survivorship after THA. Future innovation in THA should address new challenges with younger and more demanding patients, rather than change current methods that have a proven good survivorship. This innovation depends mainly upon improvements in the bearing surfaces and advances in pain control and rehabilitation.

“…The 5 different cups evaluated included different radii, porous-coating, macrotextured surfaces and peripheral fins designs and we could not detect a better intraoperative fixation for any 1 design (8, 26). To date, although porous-coated ingrowth cups are widely used, different uncemented fixation types consistently provide excellent results in terms of bone fixation (27–29).…”
