Orthopedics This Week reports on HSS study findings published in JBJS Reviews by hip and knee surgeon Peter K. Sculco, MD, and colleagues, explaining the latest liner and shell options for primary total hip arthroplasty (THA). In the paper, the authors explain how liner design may affect functional anteversion, inclination, and jump distance.

Dr. Sculco explained, “Dislocations after primary THA are devastating adverse events for patients that are potentially avoidable in many instances. Recent years have seen a considerable increase in our understanding of prosthesis placement, design, and the spino-pelvic relationship as it relates to dislocation risk. In the setting of this new and developing understanding, we thought it would be valuable for the hip surgeon to have a comprehensive guide of currently available acetabular component and liner designs that may be applied at the individual patient level to help reduce dislocation risk.”

He continued, “This review may alter practice by serving as a foundational source of knowledge for acetabular component and liner design and function, thereby allowing the hip surgeon to select the optimal liner characteristics to mitigate the risk of dislocation after primary THA for their own patients.”
