Primary Purpose: Diagnostic
|Official Title:||Evaluation of Orthopedic Knee Measurement Using Lunar iDXA|
- Efficacy of Lunar orthopedic knee software. [ Time Frame: 5 months from starting study. ]This study will compare the bone density and bone mass measurements acquired with Lunar orthopedic knee software and for the same scans acquired with Lunar orthopedic software. A determination of precision of bone measurements acquired and analyzed with Lunar orthopedic knee software.
|Study Start Date:||July 2011|
|Study Completion Date:||September 2011|
|Primary Completion Date:||September 2011 (Final data collection date for primary outcome measure)|
Experimental: Post-operative knee replacement
Subjects that have had a hemi knee replacement of one knee at least 8 weeks ago had the post-operative knee scanned using the orthopedic hip application and the Lunar orthopedic knee application.
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
