I've had the surgery on both wrists - the Right in Nov 1991 and the Left in Feb 1992. The R was convential since my R wrist area was so bad.. the L was endoscopic. Hopefully, yours is endoscopic.
I lost most of the 1992 season, plus I still have major problems, especially with the R hand. I have much less than 50% strength in my R... slightly more than 50% in my L.
Word of advice - DO the rehab. I'll repeat.. DO the rehab. Again, DO the rehab. I didn't and I am paying for it to this day. (My job at the time did not allow going to rehab 3x a week, minmum, for >1 hour rehab.)
