Supplying the ASC Surge: Adapting Orthopedic Logistics for Outpatient Surgery
Key Takeaways:
- ASC Growth Trends: By 2028, more than 60% of joint replacements will be performed in Ambulatory Surgery Centers (ASCs).
- Importance of Pre-Sterilized Kits: ASCs require pre-sterilized, operating room-ready kits, as they depend on just-in-time delivery and do not have in-house sterilization capabilities.
- The Value of Late-Night Fulfillment: Providing urgent, next-day deliveries helps maintain revenue by building surgeon loyalty and preventing missed procedures.
- Efficiency of Regional Hubs: Establishing regional distribution hubs can minimize lead times, speed delivery, and lower shipping costs.
- Need for Real-Time Visibility: Tracking every implant and kit by lot number, serial number, and Unique Device Identifier (UDI) enhances audit preparedness and improves field inventory control.
The Outpatient Revolution in Orthopedic Logistics
The field of orthopedics is experiencing a significant transformation. Over the past decade, many orthopedic surgeries—particularly total joint replacements, spine procedures, and sports medicine operations—have shifted from traditional hospital settings to ASCs. Cost considerations, advancements in surgical technologies, and patients’ preferences for outpatient care drive this change. As a result, the volume of procedures performed at ASCs has increased by over 50% in the last ten years, with projections indicating that more than 60% of all joint replacements could be outpatient by 2028.
This shift calls for more than minor adjustments; it necessitates a complete rethinking of orthopedic logistics. Traditional hospital-based distribution models cannot adequately meet the needs of ASCs, which operate with smaller facilities, faster turnaround times, limited inventory, and no on-site sterilization.
To succeed in this evolving environment, orthopedic original equipment manufacturers (OEMs) must partner with logistics providers capable of delivering supplies to ASCs with precision, speed, and compliance. Millstone Medical Outsourcing is at the forefront of this essential evolution.
The Unique Orthopedic Logistics Demands of ASCs
Supplying ambulatory surgical centers (ASCs) presents distinct logistics challenges compared to hospitals. ASCs operate with leaner setups, typically lacking large stockrooms and on-site sterilization departments. Every implant, surgical kit, and disposable item must arrive pre-sterilized, ready for the operating room, and just in time.
Given the higher daily case volumes and smaller batch sizes, OEMs must reconsider their inventory flow strategies to prevent overwhelming ASCs from causing case cancellations.
Timing is also crucial. Many surgeries in ASCs are scheduled with little notice, requiring flexible fulfillment that can adapt to daily or hourly changes. Unlike hospitals that maintain extensive safety stock inventories, ASCs depend on vendors for precise deliveries—no more, no less.
If implants, instruments, or accessories do not arrive on time, they can lead to delayed or canceled procedures, wasting operating room resources, frustrating surgeons, and jeopardizing revenue for the facility and the OEM.
Common Pitfalls When Serving the ASC Market in Orthopedic Logistics
Many OEMs and logistics providers struggle to meet the needs of ASCs because they rely on outdated hospital-based supply models.
For instance, shipping bulk inventory can overwhelm the limited storage space available at ASCs. Additionally, slow sterilization workflows can delay the readiness of surgical kits. A lack of visibility into field inventory can lead to stockouts, resulting in case cancellations. Most importantly, logistics providers that do not offer late-night fulfillment options fail to support urgent or additional surgeries scheduled outside of regular business hours.
The consequences of these issues include lost revenue, frustrated surgeons, and damaged OEM reputations. In today’s ASC-driven market, these risks are simply unacceptable.

How Millstone Solves the ASC Logistics Challenge
Millstone Medical Outsourcing strategically addresses the challenges that ASCs face.
Small-Batch, Pre-Sterilized, OR-Ready Distribution
Millstone’s ISO Class 7 cleanrooms enable us to build and package fully sterile surgical kits explicitly tailored for each Ambulatory Surgery Center’s (ASC) scheduled procedures. Our small-batch distribution model eliminates the need for large storage spaces and ensures that every implant, instrument, and disposable item arrives pre-assembled, pre-labeled, and ready for immediate use in the operating room (OR).
By pre-validating sterilization workflows, we eliminate delays that typically occur when OEMs send “clean” products that require additional sterilization. ASCs no longer need to worry about sterilizing kits on-site, because everything arrives ready for the OR with Millstone.
Late-Night Fulfillment for Urgent Add-Ons
With Millstone’s late-night order processing available until 10 PM CST, OEMs can effectively support last-minute urgent surgeries. Whether it’s an emergency add-on or a surgeon needing to fill an extra operating room block, we ensure same-day processing and overnight shipping to accommodate next-morning surgical schedules.
This flexibility allows OEMs to maintain strong relationships with ASCs and surgeons by never missing a case, even when schedules change at the last minute.
Strategic Hub Locations for Regional Distribution
Millstone’s distribution centers are strategically positioned near significant logistics corridors, enabling same-day or next-day delivery to key ASC markets.
With outpatient orthopedic surgeries expected to grow by 7–10% annually over the next several years, having access to regional hubs allows OEMs to scale their deliveries without experiencing bottlenecks or increased freight costs.
Proximity is not only crucial for speed; it also enhances predictability, control, and cost efficiency.
Real-Time Inventory Visibility
Our real-time inventory management system tracks every implant, instrument, and surgical set by lot and serial number. OEMs can quickly monitor inventory levels, track expiration dates for sterile items, and forecast replenishment needs based on surgical demand.
We ensure full Unique Device Identification (UDI) compliance, guaranteeing that every shipment meets regulatory requirements and supports rapid recall capabilities when necessary.
Seamless Reverse Logistics for Returns
Surgical teams frequently return surgical sets and unused implants after canceling or rescheduling cases. Millstone’s closed-loop reverse logistics system ensures that returned inventory is scanned, inspected, reprocessed, and redeployed within 48 hours whenever possible. This quick turnaround minimizes waste, keeps valuable assets in circulation, and reduces replenishment costs for OEMs supporting dynamic ASC networks.
Strategic Benefits of an ASC-Focused Logistics Model
By tailoring orthopedic logistics to meet the specific needs of ASCs, Millstone provides significant advantages:
- Increased Surgeon and ASC Satisfaction: Reliable deliveries and complete surgical kits eliminate delays, fostering loyalty among surgeons and centers.
- Reduced Operating Costs: Smaller shipments, real-time visibility, and optimized inventory cycles help to lower unnecessary carrying costs and expedited shipping expenses.
- Enhanced Regulatory Compliance: Pre-sterilized and traceable shipments simplify the process of preparing for audits and ensure better documentation for patient safety.
- Easier Market Expansion: OEMs can expand into more ASCs without establishing local warehouses or increasing field sales inventory.
- Scalable Growth Infrastructure: Millstone’s regional hub model and cleanroom facilities can grow alongside OEM demand, effectively supporting national and regional expansion plans for ASCs.
