Randomization for “Retro versus Trans Articular Drilling for Juvenile Osteochondritis Dissecans of the Knee: A Multicenter, Randomized Controlled Study” is a two-part process.

Part 1: The Research Coordinator enters the subject into the randomization system once the subject has consented to be a part of the trial. This way the subject will be in the system by the time s/he has surgery for the surgeon to randomize.

Helpful hits:

  1. When you enter a patient into the randomization system, the first two digits, which indicates the institution a patient is from, are automatically generated and entered. You only need to enter the set of three digits indicating the patient number and the letter indicating the side (ie If the patient ID was 11-001-R, all you enter is 001-R).
  2. When the surgeons go in to randomize a patient, they have to enter a time and date of the surgery that has to be within 96 hours following whatever time they are currently in the system. The default is to record the current time and date as most surgeons will be randomizing in the OR. If an error message pops up, make sure that the time showing is not preceding the current time, otherwise it will not go through.
