restor3d's U.S. Food and Drug Administration approval this past spring for the first all-metal patient specific instrument (PSI) in ankle arthroplasty could very likely bolster growth of the ankle replacement market, according to GlobalData. The market was estimated to be worth $309.1 million last year and is anticipated to double in size, reaching $618.7 million by 2033, the company predicts.
restor3d's newest product, Axiom PSR, joined Kinos Medical’s total ankle system, which hosts a portfolio of ankle implants.
“New developments in the patient-specific instrumentation space are sure to bolster and push forward the joint replacement market. With the approval of restor3d’s latest ankle arthroplasty product, there is a slight shift towards more customized surgeries, which are largely aided by advancements in 3D printing,” GlobalData Medical Analyst Aidan Robertson said.
The Axiom PSR functions as the bone contact interface to maintain the stability of the joint and incorporates radiographic markers to make fluoroscopic imaging possible. The all-metal resection guides, 3d printed at restor3d’s facility in Durham, N.C., ensure ideal anatomic fit and exact placement of the pre-planned cut required to place the Kinos Axiom Total Ankle System Implants. The system’s streamlined design features are focused to reduce operative time during total ankle surgeries.
“Patient-specific instrumentation works by collaborating with the operative surgeon in the design process and utilizing pre-operative imaging in order to manufacture an implant that meets the unique surgical needs of each patient," Robertson stated. "Essentially, the main goal of patient-specific instrumentation is to enhance surgical accuracy compared to that of standard instrumentation.”
While the Axiom is not the first PSI in ankle arthroplasty, it is the first all-metal PSI, made using titanium alloy to provide durability compared to implants made from ceramic or polyethylene. Although rare, one of the drawbacks of all-metal implants is patient allergic reactions to titanium.
“Standard instrumentation still dominates the ankle replacement market with major players such as Stryker and Zimmer Biomet, whereas PSI products make up a small portion. However, it is expected that the benefits of a customized surgical implant will continue to gain interest as more devices like the Axiom PSR become common in the market,” Robertson concluded.
