Do Certain Biomarkers Accurately Reflect Articular Cartilage Change Due To Physical Activity?, Alyssia Evans, Matthew Seeley
Do Certain Biomarkers Accurately Reflect Articular Cartilage Change Due To Physical Activity?, Alyssia Evans, Matthew Seeley
Journal of Undergraduate Research
Knee injury and pathology are common problems for Americans who are physically active; they affect half of all Americans who are over the age of 65, and the related annual costs are nearly twenty billion dollars. Knee pain alters running and walking neuromechanics1, and may be deleterious to knee articular cartilage. Researchers have hypothesized that if abnormal gait mechanics, due to knee pain persist, the resulting mechanical and physiological circumstances could influence genesis and progression rate of chronic knee joint pathologies, including knee osteoarthritis.

During ambulation, lower-extremity joint angles and net moments influence knee joint load. It is unclear which mechanical variables most strongly correlate with acute articular cartilage (AC) catabolism in response to ambulation. Purpose: To determine which mechanical variables are most strongly correlated to acute AC catabolism, and to test the acute effect of ambulation speed on AC catabolism, while controlling for load frequency. Methods: 18 able-bodied subjects (9 male, 9 female; age = 23 ± 2 y; mass = 68.3 ± 9.6 kg; height = 1.70 ± 0.08 m) completed three separate ambulation sessions: slow (preferred walking speed), medium (+50% of …
The Effect Of Anterior Knee Pain On Serum Cartilage Oligomeric Matrix Protein And Muscular Cocontraction During Running, Scott T. Woodland
The Effect Of Anterior Knee Pain On Serum Cartilage Oligomeric Matrix Protein And Muscular Cocontraction During Running, Scott T. Woodland
Theses and Dissertations
Knee pain can alter lower-extremity neuromechanics and often results in functional disability. The relationship between lower-extremity neuromechanical alterations, due to anterior knee pain, and articular cartilage condition is unclear. The purpose of this study was to determine the independent effect of anterior knee pain during running on articular cartilage condition, as reflected by serum cartilage oligomeric matrix protein concentrations and muscle cocontraction duration. Seven men and five women completed a 30-min run in three different sessions: control (no infusion), sham (isotonic saline infusion), and pain (hypertonic saline infusion). Saline was infused into the right infrapatellar fat pad for the duration …
