Study Summary
The Purpose of this trial is to evaluate the use of a cross-over trial design in an osteoarthritis population. We will determine the inter- and intra-subject variability in osteoarthritis (OA) endpoints and evaluate if efficacy can be detected by measuring OA endpoints following treatment with 2 different types of analgesics in a crossover study of this design.
Primary Outcome
The severity of arthritis pain in participant's signal knee at the time of the visit was assessed using an 11-point NRS, ranging from 0 (no pain) to 10 (worst possible pain), where higher scores indicate worse pain.
Interventions
- DRUG placebo
- DRUG Oxycodone
