Restoration® Modular Revision Hip System Post Market Study

A Prospective Open-Label Evaluation of the Restoration® Modular System

The purpose of this study is to demonstrate survivorship of the femoral stem at 5 years.

The two-piece modular revision stem components are intended to be used for primary or revision total hip arthroplasty, as well as in the presence of severe proximal bone loss. This study evaluates the System in revision cases only. The stems are intended to be used with Stryker Orthopaedics femoral heads, unipolar and bipolar components, and acetabular components. These femoral stems are designed to be press fit into the proximal femur.

In addition to demonstrating survivorship at 5 years, this study will seek to gain information on four secondary objectives: radiographic stability, Harris Hip Scores, SF-36 general well-being assessment, and safety profile.

Inclusion Criteria:

• Candidates for cementless revision of a failed femoral prosthesis.

• Male and non-pregnant female patients ages 18 to 85 years of age at the time of surgery.

Exclusion Criteria:

• Patients with ongoing infection.
• Patients who are severely immunocompromised.
• Patients who are prisoners.
