Extensively Porous-Coated Stems Demonstrate Excellent Long-Term Survivorship in Revision Total Hip Arthroplasty.

Background: Extensively porous-coated cylindrical stems have demonstrated excellent results in revision total hip arthroplasties (THAs). However, most studies are midterm follow-ups and of modest cohort size. This study aimed to evaluate long-term outcomes of a large series of extensively porous-coated stems.

Measuring standing hindfoot alignment: reliability of goniometric and visual measurements.

Objective: To examine the reliability of a functional weight-bearing measure of hindfoot alignment, the standing tibiocalcaneal angle (STCA), and to compare the relative reliabilities of goniometrically and visually estimated STCAs.

Design: Prospective blinded comparison.

Setting: Sports medicine center.
