Post Approval Study of the Commercially Available U-Motion II+ Acetabular System and UTF Reduced Stem
This is a prospective, single arm, multi-center, post-approval study designed to evaluate the
 short and long term clinical performance and safety in subjects receiving primary total hip
 arthroplasty (THA) with the U-Motion II+ Acetabular System and UTF Reduced Stem.
This is a prospective, single arm, multi-center, post-approval study designed to evaluate the
 short and long term clinical performance and safety in subjects receiving primary total hip
 arthroplasty (THA) with the U-Motion II+ Acetabular System and UTF Reduced Stem. The
 acetabular and femoral components will be uncemented. Study outcomes will be analyzed and
 published when 1.) all enrolled and implanted subjects complete their 6-week follow up, 2.)
 all implanted subjects complete their 2-year follow up, 3.) at the conclusion of the study.

 It is anticipated that up to 200 subjects will be enrolled at up to 5 sites. The subjects
 will be evaluated at predetermined intervals: baseline, procedure/ discharge and 6 weeks, 3
 months, 6 months, 12 months, and 24 months post treatment for primary analysis and annually
 up to 5 years for device survivorship. The estimated study duration from first enrollment
 through completion of the final report is expected to be approximately 7 years.

 This study will be conducted at up to 5 investigational sites in the United States with
 previous clinical research experience and with adequate population of orthopedic patients
 requiring primary total hip arthroplasty.
Inclusion Criteria:

 Subjects must meet all of the following criteria to be considered for inclusion in the
 study.

 1. Subject is between 18 and 75 years of age

 2. Subject is indicated for a unilateral or bilateral total hip arthroplasty (THA) based
 on the approved labeling of the device

 3. Subject has no history of previous prosthetic replacement device or orthopedic
 surgeries on the operative hip

 4. Subject is willing and able to provide informed consent to participate in the study;

 5. Subject is willing and able to understand the purpose of the study, his/her role, and
 is available to return to the clinic/hospital for all required follow-up visits;

 Exclusion Criteria:

 -  Subjects will be excluded if, in the opinion of the Investigator, the subject does not
 qualify based on approved labeling requirements or Subject Inclusion criteria.
