- Cognitive impairment such that the individual is unable to give informed consent, complete study data collection tools or required study visits
- Age 29 years or less due to rarity of OA in this age group
- Body mass index (BMI) greater than 30kg/m(2) and BMI less than 20kg/m(2)
- Usage of nonsteroidal anti-inflammatory drugs (NSAIDs) will be allowed at study entry and during the conduct of the study. Patients will be asked to refrain from using muscle relaxers, other opioids apart from the study drug (MS Contin), AED's (anti-epileptic drugs), TCAs (tricyclic antidepressants), SSRIs (selective serotonin reuptake inhibitors) and benzodiazepines for pain control during part II and III. Patients will also be asked to refrain from having local joint injections with steroids or other agents.
