How to Choose a Hip Replacement Surgeon in California: The 7-Point Checklist
By Trusted Surgeon Team —
To choose a hip replacement surgeon in California, verify seven things: (1) annual hip replacement volume, (2) experience with your specific surgical approach, (3) complication and readmission rates versus state benchmarks, (4) the hospital where they operate, (5) their California license and board record, (6) insurance and cost fit, and (7) how they answer five direct questions. Decades of research associate procedure-specific surgeon volume and experience with fewer complications and revisions — and nearly all seven checks can be made with public data before you ever sit in a consultation. Here is the checklist, with the evidence behind each point.
1. How many hip replacements does the surgeon perform each year?
This is the single most evidence-backed question in surgery. In a study of 37,881 hip replacements, patients of surgeons performing 35 or fewer per year had higher dislocation rates (1.9% vs 1.3%) and higher early revision rates (1.5% vs 1.0%) than patients of higher-volume surgeons (Ravi et al., BMJ 2014). A 2025 analysis of 283,888 New York hip replacements found infection rates of 0.5% for surgeons above 150 cases per year, versus 1.0% for low-volume surgeons (Di Pauli von Treuheim et al., Hip International 2025). A systematic review pooling the literature reached the same conclusion: higher-volume hip surgeons were consistently associated with fewer complications, shorter stays, and fewer revisions (Malik et al., J Arthroplasty 2018).
Ask for the number for hip replacement specifically — not total joint surgeries. Our surgeon volume evidence review covers this research in depth.
2. How experienced are they with your specific approach?
Anterior, posterior, or lateral — the approach your surgeon proposes has its own learning curve. A Dutch registry study of 15,875 hip replacements estimated the anterior-approach learning curve at roughly 100 cases (Peters et al., Acta Orthop 2022), and a 2024 population study found lower-volume anterior-approach surgeons had higher complication rates (Acta Orthopaedica 2024). The research points to a practical rule: the surgeon's track record with the approach they're proposing for you matters more than which approach it is.
3. What are their complication, readmission, and revision numbers?
Volume opens the conversation; outcomes finish it. Ask for infection, dislocation, readmission, and reoperation rates — and how they compare to the California average. A nationwide analysis of 5,106 US surgeons associated lower surgeon volume with higher dislocation rates (J Arthroplasty 2024), and registry data links surgeon and hospital volume to how much patients actually improve by their own report (J Arthroplasty 2023). A surgeon who tracks and shares these numbers is telling you something; one who can't is too.
4. Which hospital will the surgery happen in?
Surgeon and hospital volume are each independently associated with joint replacement outcomes (JAAOS 2022) — so an excellent surgeon at a low-volume facility is only half an answer. Ask why this hospital is right for your case, what its joint-replacement volume is, and who manages complications if they occur after discharge.
5. Is their California license record clean?
Five minutes on the Medical Board of California license lookup shows license status, board actions, and reported malpractice judgments. CMS datasets add Medicare procedure counts by physician. Court records complete the picture. This is public information you are entitled to check — and it's part of what our analysts review, alongside surgical registries and state reporting, in every Curated Surgeon Shortlist. The honest caveat we attach to all public data: it typically lags 1–2 years.
6. Do the insurance and cost numbers work?
Confirm the surgeon and the hospital and the anesthesiologist are in-network — they can differ. Ask for the CPT codes and get a written estimate; California prices for the same operation vary widely by city and facility. Price is not a quality signal in either direction, which is why cost is one checklist point, not the checklist.
7. How do they answer five direct questions?
Bring these to the consultation:
- How many hip replacements — with this approach — did you personally perform last year?
- What are your infection, dislocation, and readmission rates, and how do they compare to the California average?
- What percentage of your cases are revisions or complex cases?
- Who handles complications if they occur, and how is follow-up coordinated?
- Why this hospital for my case?
Specific, numerical, unhesitating answers are themselves a good sign. Vagueness — "a lot," "very rarely," "don't worry about that" — is a finding too.
Where can I verify all this myself?
Every check above runs on public data: the Medical Board of California, CMS physician datasets, surgical registries, court records, and hospital reporting. The data exists; the work is assembling it. Our data-driven guide to finding a trustworthy surgeon in California maps each source, and our methodology page shows exactly how we synthesize them — with a human analyst reviewing every case — into a ranked shortlist of three California surgeons with written rationale.
FAQ
How many hip replacements per year should my surgeon do? Research associates better outcomes with surgeons above roughly 35–50 hip replacements per year, and high-volume specialists in registry studies often exceed 100–150. Ask for the procedure-specific number, not total surgeries.
Does it matter if my surgeon is fellowship-trained? Board certification and fellowship training are baseline credentials worth verifying — but they are floor, not ceiling. Research points to annual procedure-specific volume and measured outcomes as the stronger differentiators among credentialed surgeons.
Is the anterior approach better than the posterior approach? The research suggests a more useful question: how experienced is your surgeon with the approach they're proposing? The anterior approach carries a learning curve of roughly 100 cases, and lower-volume anterior surgeons show higher complication rates. An experienced surgeon in either approach beats an inexperienced one in the "better" approach.
How do I check a surgeon's record in California? Use the Medical Board of California license lookup for license status, board actions, and malpractice judgments; CMS datasets for Medicare procedure volume; and court records for litigation history. All are public.
Should I get a second opinion before hip replacement? A second opinion validates the treatment plan — whether you need surgery. Surgeon selection answers who should perform it. They're different questions; careful patients answer both.
