ISTA 2025 - Mid-Term Clinical and Radiographical Outcomes of a 3D Printed Porous Acetabular Shell in Primary Total Hip Arthroplasty

Description

This video transcript discusses the characteristics of cancellous bone and how they relate to the design and effectiveness of 3D printed acetabular shells, specifically the trident two from Stryker. The focus is on a seven-year clinical study involving 670 patients across 20 centers who received this implant. Key statistics include a gender breakdown of 44% men and 56% women, with a mean age of 62.8 years and an average BMI of 30. Most implants were unilateral, with only 3% being bilateral. The study evaluated adverse events and device survivorship, utilizing radiographic assessments by an independent reviewer to assess implant stability. Patient outcomes were measured using the Harris Hip score and EQ-5D tools for those with at least one year of follow-up. Overall, the study aims to report long-term outcomes to inform on the viability and effectiveness of the 3D printed implant in promoting biological fixation and osseointegration.
