MDR - M/L Taper With Kinectiv Technology Stems and Necks

December 27, 2024 updated by: Zimmer Biomet

Post-market Clinical Follow-up Study to Provide Safety, Performance and Clinical Benefits Data of the M/L Taper With Kinectiv Technology Stems and Necks

The objective of this consecutive series PMCF study is to collect data confirming safety, performance and clinical benefits of the M/L Taper with Kinectiv Technology Stems and Necks when used for primary or revision total hip arthroplasty (implants) at 1,2,5 and 10-year follow-up*. ML Taper with Kinectiv Technology has been on the market since 2008, but has insufficient long term clinical data. Therefore, a prospective aspect to the study will be necessary to reach the 10-year time point.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The objective of this consecutive series PMCF study is to collect data confirming safety, performance and clinical benefits of the M/L Taper with Kinectiv Technology Stems and Necks when used for primary or revision total hip arthroplasty (implants) at 1,2,5 and 10-year follow-up*. ML Taper with Kinectiv Technology has been on the market since 2008, but has insufficient long term clinical data. Therefore, a prospective aspect to the study will be necessary to reach the 10-year time point.

The primary objective is to confirm safety of the study products. This will be assessed by recording the incidence and frequency of revisions, complications, and adverse events. Relationship of the events to either implant or instrumentation should be specified.

The secondary objective is the assessment of performance and clinical benefits by analyzing recorded patient-reported clinical outcomes measures (PROMs).

*Follow-up with the patient at the 10 year time point will be collected by the site prospectively and the 1, 2 and 5 year time point data will be collected by the sponsor retrospectively from an existing database including ML Taper with Kinectiv Technology patients from a Zimmer Biomet hip registry.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Device safety assessed through the frequency and incidence of revisions, complications and adverse events
Time Frame: Out to 10 Years.
The primary objective of this study is the assessment of the safety by analyzing implant survivorship. This will be established by recording the incidence and frequency of revisions, complications, and adverse events. Relation of the events to either implant or instrumentation should be specified.
Out to 10 Years.
Device safety assessed through radiographic assessments
Time Frame: Out to 10 Years
The primary objective of this study is to assess the safety of the device by reviewing radiographic data post implantation for each patient. A radiograph will be taken at each follow-up time point and reviewed by the surgeon to assess the frequency and incidence of any device related issues that may show up.
Out to 10 Years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Device Performance and Benefits evaluated through the Harris Hip Score outcome measure.
Time Frame: Out to 10 Years
The HHS is divided into 4 sub-categories; pain (44 points), function (47 points), range of motion (5 points), and absence of deformity (4 points). Patients select a discrete set of answers which correspond to predefined point allocations based on the category. To obtain a final score, these values are summed.
Out to 10 Years
Device Performance and Benefits evaluated through the EuroQolo Five Dimensions Questionnaire (EQ5D) outcome measure.
Time Frame: Out to 10 Years

The EQ-5D measures 5 dimensions of general health; mobility, self-care, usual activities, pain/discomfort, and anxiety/depression, with a total of 5 questions. It is accompanied by the patient's self-assessment with the VAS. There are three versions of the EQ-5D; 3 level (3L), 5 level (5L), and a youth (Y) version based off of the 3L model.

Each dimension is assigned one of three discrete levels for evaluation on the day of administration for the three level evaluation:

Level 1 - No problems, no disability Level 2 - Some problems, moderate disability Level 3 - A lot of problems, severe disability

The final score is a five digit composite of the responses ranging between 33333 - 11111 with 243 possible combinations in between for the 3L test. The 5L test can measure 3,125 different health states and ranges between 55555-11111.
Out to 10 Years
