Insights

The FDA approval of Oxford® Cementless Partial Knee represents a significant market opportunity for Zimmer Biomet. This device addresses a clear gap in the U.S. market as the only FDA-approved cementless partial knee implant, backed by impressive clinical data showing 94.1% implant survival rate at 10 years. The technology's track record of over 300,000 procedures globally and superior outcomes compared to traditional cemented implants positions ZBH for potential market share gains in the $8.5 billion knee replacement market.

The cementless approach offers compelling advantages: improved surgical efficiency, reduced OR time and better long-term fixation. These benefits could drive adoption among surgeons and healthcare facilities looking to optimize costs and improve patient outcomes. The Q1 2025 launch timeline gives ZBH time to properly train surgeons and build a strong commercial foundation.

This approval has significant revenue implications. The partial knee replacement market segment is growing faster than total knee replacements, driven by younger, more active patients seeking less invasive options. The cementless technology's reduced OR time and elimination of cement-related costs provide compelling economic benefits for healthcare facilities. The lifetime warranty offering is a strategic differentiator that could accelerate market adoption and protect pricing power.

Based on the device's established success in other markets and unique position as the only FDA-approved cementless partial knee in the U.S., this could generate meaningful revenue growth for ZBH's knee segment starting in 2025, potentially adding $200-300 million in annual revenue within 3-4 years of launch.

WARSAW, Ind., Nov. 25, 2024 /PRNewswire/ -- Zimmer Biomet Holdings, Inc. (NYSE and SIX: ZBH), a global medical technology leader, today announced U.S. Food and Drug Administration (FDA) Premarket Approval Application (PMA) Supplement approval for the Oxford® Cementless Partial Knee. The approval is based on safety and effectiveness data from an Investigational Device Exemption (IDE) study and non-clinical testing for cementless partial knee replacement (PKR).1 The Oxford Cementless Partial Knee allows surgeons to perform a PKR with improved fixation,2 better long-term implant survival rate2,3 and improved efficiency in the operating room4 (OR) compared to the Oxford Cemented Partial Knee procedure.  Following more than 20 years of clinical experience and over 300,000 procedures across Canada, Europe, Middle East, Africa, and Asia,5 the Oxford Cementless Partial Knee is now the only FDA-approved cementless partial knee implant in the U.S.

"Cementless knee replacement procedures are increasingly preferred by surgeons seeking to improve surgical efficiency. The Oxford Cementless Partial Knee is coming into the U.S. with a proven track record of retaining more healthy anatomy with a less invasive approach and improved outcomes6 as compared to a total knee replacement," said Joe Urban, President, Knees at Zimmer Biomet. "We are excited to address the unmet U.S. demand for a cementless partial knee with a new offering which has 20 years of clinical experience in more than 50 countries.5"

Compared to traditional partial knee replacements that use bone cement to secure the implant in place, a cementless approach allows patients' natural bone growth to secure the implant for better long-term fixation.2 The Oxford Cementless Partial Knee features a mobile bearing that can move with the femoral component throughout the entire range of motion to mimic natural knee movement. This design provides better range of motion, a more natural feel and a more stable implant-to-bone fixation for improved long-term implant survival.2,3 The system's tibial and femoral components have a titanium and hydroxyapatite coating to promote bone growth into the implant7. The UK national joint registry has more than 33,000 patients treated with Oxford Cementless Partial Knees recorded with a 94.1% rate of implant survival at 10 years after surgery,3 which is higher than the average 10-year survivorship for all other partial knees (89.9%).3 Enthusiasm and usage of partial knee replacement continues to grow around the world as published research continues to demonstrate that PKR in appropriate cases provides improved patient outcomes compared to TKR.6

"For younger and more active patients, the Oxford Cementless Partial Knee amplifies the benefits of a traditional partial knee replacement by offering knee flexion that resembles natural knee movement, and stronger adhesion of the implant to the bone for better long-term durability," said Adolph V. Lombardi Jr., MD, FACS, President of JIS Orthopedics in New Albany, Ohio. "In my own practice, a cementless approach has increased OR efficiency by shortening my surgery time and reducing costs associated with cement preparation."

Since its initial launch in England in 2004, the Oxford Cementless Partial Knee has become the preferred partial knee implant for Zimmer Biomet's European customers.5

As part of the U.S. nationwide launch in Q1 2025, Zimmer Biomet will provide FDA-required training, focusing on the cementless surgical technique and proper patient selection. For patients in the U.S., the Oxford Partial Knee is the only implant with a lifetime limited warranty that covers the cost of Zimmer Biomet replacement implants.*

Important Safety Information:

The Cementless Oxford Partial Knee System is intended for use in unilateral knee procedures with osteoarthritis or avascular necrosis limited to the medial compartment of the knee. It is intended to be implanted without the application of cement for patients whose clinical condition would benefit from a shorter surgical time compared to the cemented implant. The Oxford Partial Knee is not indicated for use in the lateral compartment or for patients with ligament deficiency, or for use in simultaneous bilateral surgery or planned staged bilateral procedures. Potential risks include, but are not limited to, loosening, dislocation, fracture, wear and infection, any of which can require additional surgery.
