46The goal of this clinical research study is to determine if there is a difference in time to meet return to sport criteria for Pediatric patients with apophysitis of the knee who receive iontophoresis with Dexamethasone Sodium Phosphate (DSP) and Physical Therapy (PT) as those who receive iontophoresis with placebo and PT or PT alone.
Approximately 147 patients will be enrolled in this study.
Iontophoresis is a treatment that allows medication to be delivered across your skin to the painful area without having to have an injection into your muscle or soft tissue, through a vein in your arm, or taking a pill. Instead, liquid medication is placed on a patch (like a large Band-Aid) and then placed on your knee over the location where it hurts. A plastic device, like a battery, is then attached to the patch for three minutes. During this time, this device begins to deliver the medication through your skin and into the area that hurts, and also charges the patch so it can continue to deliver the medication for two hours once the device is removed. The medication is delivered by a mild electrical current. The most common drug used with iontophoresis for pain caused by such things as apophysitis of the knee is dexamethasone sodium phosphate (dexamethasone).
This is an investigational study. Dexamethasone is a steroid medication that has been approved by the U.S Food and Drug Administration (FDA) to treat many types of problems (such as joint problems, skin and allergy problems, eye, stomach, and lung problems), but has not been approved to treat apophysitis of the knee using iontophoresis. In this study, it is an experimental drug.
Participants will be randomized to one of three treatment groups:
Physical therapy with iontophoresis using Dexamethasone
Physical therapy with iontophoresis using an inactive drug called a placebo
Physical therapy alone
Participants will be asked to attend study visits twice/week for up to 8 weeks or until they are able to pass the Return To Sport Checklist, whichever is sooner. Participants will the receive a 30-Day Follow Up phone call and complete a survey at the 90-Day mark, making each participant's study duration approximately five (5) months.

Iontophoresis is a non-invasive delivery mechanism for transmitting a medication to a local area of the body. The I-Bresis™ System and I-Bresis™ Patch will be the delivery system used for this study. The I-Bresis™ Patch is an adhesive patch. 1.5 ml of the dexamethasone sodium phosphate (4ml/1mL) will be placed on one side and 1.5 ml of 0.9% sodium chloride (saline) solution will be placed on the other. Duration of exposure: 123 minutes. Frequency of exposure: twice per week for a total of 12 sessions over a maximum of 8 weeks or until Return to Sport Criteria are met, whichever is sooner. Participants will also receive the standard PT protocol for apophysitis of the knee. This will involve up to 20 visits.
