I'd see if your surgeon's office could fax you their rehab protocol which will outline what you should be doing at each week post-op; the main thing is not to put undue stress on the repair; you'd be safe lying down, putting your ankle above your heart level and wiggling the toes (not ankle just yet) frequently to help control swelling then let the doc fit your brace; you really should wear the brace at a comfortable angle when moving about just in case you trip and suddenly put weight through the foot; this is admittedly conservative advice, but why risk re-injury?
