Brief Summary

Knee osteoarthritis (OA) can result in significant pain and limitation of function. A number of topical non-steroidal anti-inflammatory drugs have been shown to reduce pain in this condition. This study examines a different topical approach, utilizing a topical anesthetic agent, to evaluate if application of such an agent would provide relief of exercise-induced knee pain in people with knee OA.

Outcome Measures

Primary Outcomes (1)

  • Index Knee Pain Scores on a Numeric Rating Scale (NRS)

    Subject rated index knee pain 5 minutes after stopped experimental exercise (with intervention). Index knee pain was reported using the Numeric Rating Scale, a scale from 0 to 10 where 0 = no pain and 10 = the worst pain possible.

    5 minutes after stopped exercise, performed 1 hour after intervention (patch application)

Study Arms (2)

Synera

ACTIVE COMPARATOR

lidocaine/tetracaine patch with heating component which consists of iron powder, activated carbon, sodium chloride, wood flour, water and filter paper.

Drug: Synera

Inactive Patch

PLACEBO COMPARATOR

placebo patch identical in appearance and composition (namely, the heating components) to the active patch other than lacking the lidocaine and tetracaine active ingredients.

Drug: Inactive patch

Interventions

SyneraDRUG

70 mg lidocaine/ 70 mg tetracaine topical patch applied once for 12 hours

Also known as: lidocaine/tetracaine
Synera

placebo patch applied once for 12 hours

Also known as: placebo
