How to Evaluate Orthopedic & Sports Medicine Products: A Zimmer Biomet Quality Manager's 6-Step Checklist

When I first started quality-reviewing medical device portfolios, I assumed the implant with the most surgeon buzz was the one that deserved my sign-off. That assumption lasted about three months. Then I watched a promising hip line stumble in the field because the vendor's post-market surveillance team went quiet when I asked for registry-level outcomes. The implant was fine. The system around it wasn't.

I'm a quality/compliance reviewer at Zimmer Biomet. I don't place implants or talk to patients, and I don't sit in the OR. What I do is review product lines, clinical evidence, and quality documentation before they get added to what hospitals, surgery centers, and dental clinics can buy. On average I reject about one in seven first submissions I receive. In Q1 2024, that was 14 out of roughly 130 deliverables—almost all of them rejected for missing or inconsistent specification data rather than actual product defects.

This checklist is the one I'd hand to a procurement team or a clinical review board trying to make sense of a musculoskeletal product portfolio.

It's six steps. Steps 1 through 5 are the ones you already know you should be doing. Step 6 is the one most teams skip, and it tells you more about a vendor than the entire sales deck.

Step 1: Verify the clinical evidence baseline

Sales decks are not clinical evidence. Sorry, they aren't. For every product line up for review—knee, hip, sports medicine, dental reconstruction, whatever—ask for:

• Peer-reviewed studies published in the last five years, not the 1990s paper that keeps getting recycled in the bibliography.
• Registry data (National Joint Registry, AOANJRR, or your local equivalent), stratified by implant version where possible.
• Disclosure of which studies the vendor funded and which were independent.

This is also the time to check regulatory status. Which FDA 510(k) clearance or CE mark covers this exact device version? How long ago was it granted? What post-market surveillance obligations came with it? I can't tell you how many procurement conversations I've seen start with "we love this implant" and end with "oh wait, that size was never cleared."

Step 2: Scrape beyond the hero product in the portfolio

Approving a single product is easy. Approving a product system is harder. With a vendor like Zimmer Biomet, you're rarely looking at one device—you're looking at a portfolio across recon, sports medicine, dental, and enabling technology. The quality review should follow the same scope.

If you're evaluating Zimmer Biomet sports medicine products, for example, don't stop at the flagship anchor or graft system. Ask:

• Does the portfolio cover the full range of what your surgeons do, including biologics augmentation and revision cases?
• Are the instruments compatible across generations, or does adding a new product version mean buying an entire new tray?
• What's the shelf-life and backup-size situation? Expired implant inventory is a recurring quality complaint in hospitals, and it usually happens when procurement didn't check the product line's size range and turnover projections.

On the reconstruction side, make sure Zimmer Biomet dual mobility products are on your evaluation list. The dual mobility concept—a mobile polyethylene liner that articulates with both the femoral head and the outer shell—consistently shows lower dislocation rates in clinical literature, particularly for revision patients and older adults with higher instability risk. But here's the quality angle: the design rationale differs between manufacturers. Some use a captive liner with specific tolerance requirements; others rely on a different capture mechanism. Ask the vendor to walk you through their dual mobility engineering rationale in detail. If they can't, that's an answer too.

Step 3: Watch the surgical workflow, not just the implant

An implant that adds 30 minutes to an operation is a bad implant from the wallet's perspective. This is where robotics and enabling technology come into the picture.

Zimmer Biomet's ROSA platform is a good example because it's often misunderstood as a selling point rather than a workflow tool. When I review ROSA-related product lines, I check the same things I check for manual instruments: Does the planning-to-surgery process actually shorten the OR schedule? Is the intraoperative imaging protocol realistic for a busy surgical center? Are the technique guides written in a way an OR team can actually follow?

If a vendor won't let you shadow a live case or share the surgical technique guide before contract discussions, treat it as a yellow flag. In my experience, the right vendors are almost eager to show you the workflow, because it's where their product either wins or loses.

Step 4: Treat training as a deliverable, not a slide deck

A hospital can buy an excellent implant system and then watch it underperform because the training consisted of a 30-minute lunch-and-learn. Ask what the education pathway actually includes: cadaver lab slots, case observation at an experienced center, digital planning support for the first five real cases?

Zimmer Biomet invests heavily in medical education—cadaver labs, training centers, and digitized technique modules. It's not charity; it's a quality mechanism. Devices used by well-trained teams fail less. If the vendor you're evaluating can't point to a concrete training pathway, that's a data point.

Step 5: Demand post-market surveillance transparency

Just about every manufacturer produces a clean ISO 13485:2016 certificate. That's table stakes. The question is what happens when something goes wrong in the field.

Ask the vendor for post-market surveillance summaries from the last two years, field safety notices and their root-cause analyses, and how complaints are triaged. Even better, ask how your hospital's own usage data would feed back into their monitoring. Transparency in post-market review is one of the things that separates a mature quality system from a paper compliance program. I'd probably turn down a product line with perfect clinical data if the vendor couldn't explain how they track a device after it's out of their hands.

Step 6: Ask where the vendor's expertise ends

Here's the step I've never seen on another procurement checklist.

Sit down with the vendor and ask them, directly:

"What do you NOT provide? And who should we call instead?"

I'll give you honest answers from my side of the table. If a procurement lead asks me about a power wheelchair for patient mobility, I'll tell them that's outside Zimmer Biomet's scope. We build implants and surgical robotics, not rehab equipment. A specialized rehabilitation technology vendor is a better partner for that conversation. Same story with a cardiac monitor: if a hospital is outfitting a post-operative care unit and wants my opinion on patient monitoring, I can talk about what complications are relevant after joint replacement, but the cardiac monitor itself is a cardiovascular device question, and the right specialists are the companies that build those monitors.

It's also worth having a basic conversation about imaging. One procurement director asked me a dead simple question once: how does an MRI machine work, and does Zimmer-Biomet have experience supporting MRI-related procurement decisions? I had to be honest: I'm not an imaging physicist, so I can't speak to magnet engineering or sequence design. What we CAN do is tell you how our implants behave in the MRI environment—which materials are safe, what artifact patterns to expect. For the machine itself, you want an MRI vendor. That's their expertise, not mine. It's also why I tend to be skeptical when a device vendor claims competence across every corner of a hospital's equipment list. That's the old "we do everything" pitch, and in medical devices, it usually means they do a few things well and everything else at 70%.

The point isn't to catch a vendor off guard. It's to see whether they respect the boundary between what they've actually studied and what they haven't. A vendor who can say "this isn't our strength—here's who does it better" earns my trust for every other part of the engagement.

The mistakes that keep coming back to me

Three evaluation errors keep winding up on my desk:

1. Choosing an implant based on a single surgeon's anecdote. One surgeon's great experience is a story, not a trend. Registry data and multi-center studies are the trend.

2. Comparing only implant prices. The implant can be 8% cheaper and still lose because training is thinner, OR time is longer, or the instrument re-processing is more complicated. In a blind cost comparison in 2023, our team found a "budget" line running 11% over the premium line per procedure once those variables were included.

3. Asking the scope question too late. Asking "what else should we consider?" in week one is easy. Asking it in week eight, after the committee has already talked itself into a product, is nearly impossible. Put the scope question at the beginning of your review, not the end.

Bottom line

Quality reviews and professional boundaries share the same logic: the most useful answer is sometimes "this isn't us." I'd rather work with a specialist who knows their limits than a generalist who overpromises. Use this checklist for your next musculoskeletal product evaluation. Steps 1 through 5 will tell you whether a vendor is competent. Step 6 will tell you whether they're honest. You need both.
