Hemi Knee Arthroplasty
Device: iDXA knee software
||Endpoint Classification: Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
||Evaluation of Orthopedic Knee Measurement Using Lunar iDXA
Primary Outcome Measures:
| Study Start Date:
| Study Completion Date:
| Primary Completion Date:
||September 2011 (Final data collection date for primary outcome measure)
Device: iDXA knee software
Following surgery, subjects who have undergone knee arthroplasty will have the knee that has undergone arthroplasty (post-operative) scanned at least 8 weeks after surgery.
During one visit, each subject will have the post-operative knee scanned 1 time using Lunar orthopedic application, and 3 times with the subject repositioned between scans using the Lunar orthopedic knee application (total of 4 scans). Lunar iDXA measurement procedures will be done
