Questions to Ask an Orthopedic Surgery Expert Witness at Deposition (2026 Guide)

By John Mahoney · Updated 2026-09-01 · 18 questions in 4 concession chains

You are about to cross-examine someone with two decades of training you don't have, on their home turf, about the thing they do every day. That asymmetry is the defining problem of medical-expert depositions — and it gets worse in multi-defendant malpractice cases, where two to four different specialties can be in play in a single case and you have to be conversant in all of them by deposition day.

Orthopedic experts testify about compartment syndrome, post-operative infection, hardware complications, and nerve injury. Compartment-syndrome cases in particular are timing cases — and the orthopedic literature’s own teaching about warning signs is the plaintiff’s best material.

The answer to the asymmetry is not to learn orthopedic surgery — it is structure. A concession funnel asks the expert to agree, one fact at a time, to propositions so orthodox that refusing them costs more credibility than granting them. The questions below are a generic-case-safe starting bank, organized into the four chains that structure works through.

How to use these questions

Every question below follows three rules of expert cross-examination: it is leading (it states a fact and asks for agreement), it contains one fact (no compounds — a compound question lets the witness answer the easy half), and it belongs to a concession chain (each answer narrows the room the next answer can live in). Ask them in order. When you get the concession, stop — do not ask the "why" question that lets the expert explain it away.

Chain 1 — Qualifications, retention & scope

Goal: establish on the record that this is a paid, retained witness who never touched the patient, and fix the boundaries of what they actually practice.

Doctor, you were retained by opposing counsel in this case, correct?
You are being compensated for your time reviewing this case and for your testimony today, correct?
You never examined or treated the patient in this case, correct?
Everything you know about this case comes from the materials counsel selected and sent to you, correct?
Orthopedic surgery includes subspecialty areas — spine, trauma, joint replacement, hand — and you do not practice all of them, correct?

Chain 2 — Bases-of-opinion lockdown

Goal: freeze the universe. After this chain, any new document, new basis, or new opinion at trial is impeachment material.

You have now told us every document and material you reviewed in forming your opinions, correct?
You are not relying on anything outside that file for the opinions you will give in this case, correct?
You have told us every opinion you intend to offer at trial, correct?
You agree that an opinion you cannot state to a reasonable degree of medical probability is speculation, correct?

Chain 3 — Substantive concessions: compartment syndrome and post-operative warning signs

No orthopedic expert can deny the core teachings about compartment syndrome — they are drilled into every resident. That makes them the safest possible foundation for a timing case.

Compartment syndrome is a surgical emergency, correct?
Pain out of proportion to the injury is a recognized warning sign of compartment syndrome, correct?
Delay in treating compartment syndrome can cause permanent damage, correct?
Neurovascular checks after an injury or surgery exist to catch these complications early, correct?
Signs of infection after an orthopedic procedure call for evaluation, correct?
The imaging in this case is objective data — the films are what they are, correct?

Chain 4 — Closing the doors

Goal: end with the record sealed. These questions convert silence into a commitment that nothing new is coming at trial.

You are not offering any opinions in this case beyond the ones we have discussed today, correct?
You have not held back any opinion or criticism that you intend to offer at trial, correct?
You are not offering any opinion about the physical-therapy or rehabilitation care in this case, correct?

These are the generic questions. Your case isn't generic.

Where lawyers get burned deposing orthopedic surgery experts

Letting "patients vary in pain" defeat the warning sign

The defense line is that pain is subjective and post-operative pain is expected. Do not argue pain thresholds. Lock the concession that escalating pain — pain that is worsening despite treatment — is exactly the pattern the warning sign describes, then walk the chart’s pain entries in time order.

Conflating hardware failure with hardware placement

Hardware can fail without negligence; hardware can also be malpositioned from the start. Experts blur the two because the first is defensible. Use the imaging to make the expert commit to position at each film before discussing failure.

Skipping the documentation gaps in neurovascular checks

Orders for checks are not the same as performed checks. If the flowsheet has gaps, walk them one by one. An expert who fills gaps with "it was surely done" is now testifying from assumption, and has said so on the record.

FAQ

What questions should I ask an orthopedic surgery expert witness at deposition?

Work in four concession chains: (1) qualifications, retention, and scope — establish the expert was retained, is compensated, never treated the patient, and what they do and do not practice; (2) bases-of-opinion lockdown — pin every document reviewed and every opinion they intend to offer; (3) the orthopedic surgery-specific substantive chain — well-established propositions such as "Compartment syndrome is a surgical emergency"; and (4) closing the doors — confirm on the record that no undisclosed opinions remain. Every question should be leading, contain one fact, and build on the prior answer.

How do I cross-examine a medical expert when I never went to medical school?

You don't out-doctor the doctor — you build concession chains from propositions so well-established that a credible orthopedic surgery expert cannot refuse them, then apply those concessions to the facts in the chart. The expert's medical training becomes your asset: the more orthodox the proposition, the more it costs them to fight it. The asymmetry problem is real — especially in multi-defendant cases with two to four specialties — which is why the questions are organized as funnels rather than as debates.

What are the biggest traps when deposing an orthopedic surgery expert witness?

The classic traps are arguing about subjective pain thresholds instead of locking in that escalating pain despite treatment is the textbook warning pattern, letting the expert blur hardware malposition with later hardware failure, and failing to walk the documentation gaps in ordered-but-unrecorded neurovascular checks.
