Biospecimen Retention: None Retained

Biospecimen Description:

Estimated Enrollment:	32
Study Start Date:	May 2008
Estimated Study Completion Date:	May 2010
Estimated Primary Completion Date:	May 2010 (Final data collection date for primary outcome measure)

Groups/Cohorts
1 24 adults with meniscal damage for which arthroscopy is clinically indicated
2 8 adults who have already undergone meniscal resection to serve as positive controls

Detailed Description:

This study will test the hypothesis that knee trauma (as exemplified by the arthroscopy procedure) causes inflammation that alters muscle activation patterns locally and also disrupts the balance between parasympathetic-sympathetic reflexes. It is hypothesized that these factors contribute to development and progression of knee osteoarthritis.
