In medical astrology, you are ascendant, the 7th house ruler is the physician, and the 10th house shows the cure.
Your doctor looks pretty good, Mercury in rulership and exaltation.
You are not in great shape, but you don't need astrology to tell you that. Moon-Saturn conjunction on the ascendant can well be indicative of a chronic bone problem, and maybe something hormonal, that's difficult to diagnose - moon/Saturn is also at the bendings (square to the nodes).
Here's my concern: The tenth house, a/k/a the cure (surgery in this case) does not look like it would prove useful right now. You've got a fallen sun sitting on the MC, and the ruler of the MC is in detriment in the 11th house/12th sign.
Can you talk to your surgeon or doctor about any alternatives, or tests that might not have been done yet that could be useful before trying surgery again? Again, it looks like he or she is a capable person, so they might be amenable to this.
