Allofit® IT With HXPE in Total Hip Arthroplasty

Status Active, not recruiting

Clinical Trial Summary

The study design is a multi-center, prospective, non-controlled, consecutive cohort postmarket clinical follow-up study to obtain survival and outcome data on the Allofit IT Shell in combination with Longevity Liners in primary total hip arthroplasty.

Clinical Trial Description

The study will involve orthopedic surgeons skilled in total hip arthroplasty and experienced with the implants subject of this study. In total, 5 centers will be involved. This number of clinical sites will permit assessment of the consistency among a multitude of Investigators. A total number of 200 subjects will be included in the study. It is anticipated that each clinical site will enroll 40-60 eligible study subjects, who have provided written informed consent. Ethics Committee (EC) approval for each site has to be obtained prior to conducting this research. Sequentially, all eligible patients will be offered study enrollment at each center to avoid potential selection bias. All potential subjects will be required to participate in an informed consent process and sign an EC approved written informed consent prior to study enrollment. It is anticipated the enrollment period may be 12 months or longer to assure an adequate number of cases at each site. Each case enrolled will receive an Allofit IT HXPE Bearing System. The study is designed to be prospective to ensure that the study population is representative of the type of population that the device is intended to treat. The subjects included will be candidates for All subjects will undergo preoperative clinical, functional and radiographic evaluations, total hip arthroplasty, immediate post-operative evaluations and post-operative clinical, functional and radiographic evaluations at 6 months (± 1 month), 1 year (± 2 months), 2 year (± 2 months), 3 year (± 2 months), 5 year (± 2 months), 7 year (± 2 months), and 10 year (± 2 months). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
