WARSAW — Texas-based surgical funding company MedStar has been court-ordered to turn over information pertaining to DePuy-manufactured artificial hips.

According to a Reuters report, Johnson & Johnson-owned DePuy requested the order in light of lawsuits filed by surgery patients who received the artificial hips. In response, U.S. District Judge, David Katz, ordered MedStar to provide the information no later than Nov. 13, stating it was necessary in order to assess whether liens placed against 11 personal-injury settlements are valid.

The report went on to day that DePuy expressed concern that MedStar may be attempting to gain excess profits on the liens, which they say should not have cost more than $336,000 but that MedStar said cost $1.5 million. MedStar founder, Dan Christensen, denied these claims by DePuy.
