Patients in the cryotherapy group will have the ice water in their cryotherapy device maintained continuously for 2 days from initial application as this is the reported time of average patient disability and children typically return to school by post-operative day 3. The device will not be placed directly on the skin to minimize tissue damage. An additional protective barrier pad included with the cold therapy device will provide a barrier between the skin and the cooling device. This allows for continuous cooling at a higher target skin temperature. Aside from the cryotherapy, all surgical treatment will be standard of care.
