Cementless Total Hip Arthroplasty in Young Patients

The International Society for Technology in Arthroplasty (ISTA)



Abstract

Cementless arthroplasty has progressed substantially in the recent decades from pressfit implantation to porous-coated and later HA-coated implant fixation as its ultimate current state-of-the-art incarnation. As a consequence ever younger and older patients have received the benefits of hip and other arthroplasty although attention to age-related factors is key to success. Key factors for success, from the implant perspective, are adequate primary stability of the device in the bone supported by design and surface structure variables that together with optimal implant biocompatibility result in durable osseo-integration of the device. The high activity levels of younger patients but similarly the generally inferior muscular condition of elderly patients require special attention for the stability of the hip joint with avoidance of impingement. Also bone quality may be a topic for consideration to avoid problems. Excellent survival rates past twenty years are documented in both literature and registries with quantitative studies confirming the excellent implant stability and bone quality. With an optimal consideration for patient related factors as well as anatomic reconstruction of the arthroplasty, modern cementless arthroplasty provides every patient an outlook on both excellent long term functionality and survival.
