MDR - PMCF Study for Taperloc Complete Stems

Study Overview
=================
Brief Summary
-----------------
The objective of this consecutive series PMCF study is to collect data confirming safety, performance, and clinical benefits of the Taperloc Complete stems when used for primary or revision total hip arthroplasty (implants) at 1,3,5,7 and 10-year follow-up*. Since Taperloc Complete was introduced to the EU in 2010, all available retrospective data will be collected from each patient and a prospective aspect to the study will be necessary to reach the 10-year time point.

Detailed Description
-----------------
The objective of this consecutive series PMCF study is to collect data confirming safety, performance, and clinical benefits of the Taperloc Complete stems when used for primary or revision total hip arthroplasty (implants) at 1,3,5,7 and 10-year follow-up*. Since Taperloc Complete was introduced to the EU in 2010, all available retrospective data will be collected from each patient and 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). *The most recent available data will be used. If any of the listed time points are not available, data will be used from last available time point and follow-up will move forward at the closest available time point

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Device Safety assessed through the frequency and incidence of revisions, complications and Adverse Events. | The primary objective of this study is the assessment of 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 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Device Performance and Benefits evaluated through the Harris Hip Score | 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 Oxford Hip Score | The OHS is a patient-completed, 12-question evaluation. Each item is scored from 1 to 5, with 1 representing best outcome/least symptoms and 5 representing worst outcome/most symptoms. | Out to 10 Years |
