|Osteoarthritis Avascular Necrosis of Bone of Hip Post-traumatic; Arthrosis Congenital Hip Dysplasia||Device: Vivacit-E Liner||Not Applicable|
Safety will be evaluated by monitoring the frequency and incidence of adverse events.
Performance will be determined by assessment of the overall pain and functional performances, survivorship, health status and radiographic parameters of all enrolled study subjects who receive the Vivacit-E HXPE Liner with the Continuum acetabular shell.
In addition, the implanted Vivacit-E HXPE Liners will be evaluated for bedding in, and linear and volumetric wear by the Martell 2-D method at 6 weeks and 1, 2, 4, & 5 years postoperatively.
Pain and functional performance will be measured using the Harris Hip and High Activity Arthroplasty Scores. Survivorship will be based on removal or intended removal of the device and through analysis of radiographs, and health status will be determined by evaluation of the EQ-5D.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||258 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||Post Market Clinical Follow-up Study of the Zimmer Vivacit-E Highly Crosslinked Polyethylene Liner Used With the Continuum Acetabular Shell|
|Study Start Date :||March 2013|
|Estimated Primary Completion Date :||March 2, 2026|
|Estimated Study Completion Date :||June 30, 2028|
All subjects enrolled receive the study implant.
Device: Vivacit-E Liner
All subjects enrolled will receive the Vivacit-E liner.
- Survival of the study device; whether or not it is still implanted in the subject [ Time Frame: 10 years ]Survival is classified as removal of the study device for any reason
- Incidence of treatment-emergent Adverse Events (safety) [ Time Frame: 10 years ]Safety is assessed by monitoring the frequency and incidence of all adverse events, with particular focus on those that may be related to the study device.
- Harris Hip Score [ Time Frame: 10 years ]Functional outcomes are measured with the Harris Hip Score, including range of motion, pain level, activity levels and patient satisfaction.
- Patient activity level [ Time Frame: 10 years ]Patient activity level is assessed with the High Activity Arthroplasty score, filled out by the patient.
- Patient Quality of Life [ Time Frame: 10 years ]This is another self-assessment by means of the EQ-5D score, which measures the patient's perceived quality of life.
- Radiographic analysis [ Time Frame: 2 years ]Patient x-rays will undergo a Martell analysis by Dr. John Martell to evaluate radiolucencies, osteolysis, sbusidence, cup migration and polyethylene wear.
