Study Population |
Patients who received Wright Medical Technology metal-on-metal hips in the post-market environment.
|
Sample Size |
120 control patients, 380 with THA, 10 clinical sites
|
Key Study Endpoints |
Serum and whole blood cobalt and chromium level comparison between unrevised and revised subjects. Secondary endpoints include ALTR, radiographic outcomes, Harris Hip Scores
