Every surgery carries risk. The pages of disclosures and warnings you sign before a procedure are not legal theater — they document the fact that even well-performed operations sometimes produce bad outcomes. So when a surgery goes wrong, the first question a malpractice lawyer has to answer is the hardest one in this entire area of law: was this a known risk that materialized, or was it an error that crossed the line into malpractice?
What Informed Consent Actually Covers
The informed consent documents you sign before surgery describe the realistic complications a competent surgeon would discuss with you. For most major surgeries that includes:
- Risks of anesthesia, including rare cardiovascular and respiratory events.
- Infection at or below the surgical site.
- Bleeding, including the possibility of needing transfusion.
- Damage to nearby structures (nerves, blood vessels, adjacent organs) that a surgeon can encounter even when operating carefully.
- Specific procedure complications — for example, leak after bowel anastomosis, nerve injury after spine surgery, instrument failure during certain procedures.
- The possibility that the procedure will not achieve the intended result.
If one of these complications happens despite the surgeon doing everything correctly, that is generally a known risk — not malpractice. The legal system does not hold surgeons responsible for outcomes that fall within the band of known complications a competent operator could not have avoided.
The Errors That Are Not "Known Risks"
The errors that almost always cross the line into malpractice fall into categories courts and experts treat as "never events" — mistakes that should not happen under any reasonable interpretation of the standard of care.
Wrong-site, wrong-procedure, wrong-patient surgery
Operating on the wrong knee, the wrong kidney, the wrong vertebra, or the wrong patient entirely is not a known risk. Modern operating rooms have time-outs and verification protocols specifically designed to prevent this category of error. When wrong-site surgery happens, it is almost always because those protocols were not followed.
Retained surgical instruments or sponges
Leaving a sponge, needle, clamp, or other instrument inside a patient after closing is not a known risk. Operating rooms count instruments before and after every procedure. A retained object means the count was either not done or not done correctly.
Anesthesia errors that cause preventable harm
Anesthesia carries known risks, but specific anesthesia errors do not. Failing to recognize that a patient is becoming hypoxic, missing a drug allergy that was documented in the chart, administering the wrong concentration of a drug, or failing to manage the airway during a procedure are deviations from the standard of care, not known risks.
Damaging structures the surgeon should have identified and protected
This is the category that drives the most litigation and the most expert disagreement. The standard is whether a reasonably competent surgeon, operating in the same situation with the same view of the anatomy, would have identified and protected the structure that was injured. Some nerve and vessel injuries fall on the "known risk" side. Others — particularly injuries to clearly identifiable structures during routine procedures — fall on the malpractice side.
Failure to recognize and respond to a complication
Sometimes the surgery itself goes acceptably, but the postoperative care misses a developing complication. A patient who develops sepsis, abdominal bleeding, or a leak in the days after surgery should be monitored, evaluated, and treated. Failure to recognize the deterioration, or to act on it once recognized, is often where the case is made.
The standard is not perfection. The legal test asks what a reasonably competent surgeon in the same specialty would have done in the same situation — not what the best possible surgeon could have done. Hindsight is not the standard.
How Experts Evaluate the Distinction
The question of whether a surgical outcome was malpractice or a known risk is almost always decided by expert review of the records. Most jurisdictions require an outside surgeon in the same specialty to provide a sworn opinion, often before the case can even be filed. The expert reads the operative report, the imaging, the anesthesia record, the postoperative notes, and the hospital chart, then writes a clear opinion on whether the standard of care was met.
At The Alvarez Law Firm, Herb Borroto, M.D., J.D. reviews the records first, in-house. Because he has both medical and legal training, he can identify likely deviations before any outside expert money is spent. This screens out cases where the bad outcome was actually a known risk — which is fairer to clients and faster than the typical "send everything to an expert and see what comes back" approach.
The Records That Decide These Cases
Surgical malpractice cases turn on the operative report (the surgeon's own narrative of what happened), the anesthesia record (which is largely automated and hard to alter), the nursing notes, the recovery room flowsheet, the postoperative progress notes, and the imaging studies. When something has gone wrong, those records usually tell a consistent story — if you know how to read them.
Patients have a federal right to all of these records under HIPAA. Our companion guide on the records your lawyer needs walks through how to request them.
What This Means If You or a Family Member Had a Bad Surgical Outcome
The honest answer to "was this malpractice?" almost always requires the records. A free case review focused on a surgical outcome usually goes like this: tell us what happened, let us request the operative report and a few key documents, and within a couple of weeks we can give you a real answer rather than a hopeful guess.
If the surgery has already happened and you are wondering, do not wait. State filing deadlines vary significantly — most range from one to three years, with some allowing additional time under a discovery rule when the harm was not apparent at the time. Many states also require formal pre-suit steps that take additional months. The clock is running.
