The purpose of this study is to examine the relationship between muscle activation and heart rate on joint generalized inflammation and arthritis development.

Study summary:

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.


Inclusion Criteria: - Age 40 or older - Potential candidate for knee arthroscopy for medial - Meniscal tear confirmed on MRI - Prior meniscal resection at least 1 year prior with a persistent knee effusion - Body mass index between 25-35 kg/m2 Exclusion Criteria: - Knee injury in the 1 month before the initial study evaluation - Knee surgery within 1 year before the initial study evaluation - Pace-maker or defibrillator, 2nd or 3rd degree heart block, or other abnormal rhythms - Current diagnosis of diabetes mellitus, a fasting glucose>100mg/dl or >140 mg/dl 2 hour after a glucose challenge - Current diagnosis of an inflammatory condition (e.g. rheumatoid arthritis, gout, etc) - Untreated thyroid disease - Morbid obesity (body mass index >35) - Neuropathy or nerve damage - Stroke or transient-ischemic attacks (mini-stroke) - Recent diagnosis of congestive heart failure or heart attack - Use of prednisone or chemotherapy, steroid or other joint or ant-inflammatory agents in the past 3 months - Current use of medications that influence heart rate - Cognitive impairment that limits your ability to provide informed consent - Pregnancy
