Rounding Up the Latest Devices in Joint Replacement Surgery

The joint replacement segment makes up more than one-third of the global orthopedic market, so it’s no surprise that companies are pouring resources into the development of products that are designed to help surgeons perform safer and more effective procedures. Here are eight recent introductions that address periprosthetic joint infection, complex revision procedures, minimally invasive shoulder surgeries and cementless personalized knee arthroplasty.

Infection Management for Complex Joint Revisions

Biocomposites introduced SYNICEM hip, knee and shoulder preformed spacers in the United States. The antibiotic-loaded preformed spacers are designed to deliver a prolonged local concentration of gentamicin while preserving articular space, limb length, and joint stability during two-stage revisions. Available in a comprehensive range of sizes and styles, the SYNICEM spacer range includes a choice of Charnley and Müller hip spacer designs, and specific left and right geometries for each knee. SYNICEM spacers have been successfully used for more than 20 years in over 70 countries.

Expanded Indications for Fracture Fixation

Catalyst OrthoScience’s Catalyst Fracture Shoulder System received FDA 510(k) clearance for additional indications that now include anatomic (total or hemi) shoulder procedures, giving surgeons flexibility to treat complex proximal humeral fractures with a single, streamlined platform for both anatomic and reverse replacements. In anatomic indications, Catalyst Fracture utilizes Catalyst’s ellipsoid head design, shown to better restore natural anatomy compared to traditional spherical head designs.

Minimally Invasive Shoulder Replacement

Johnson & Johnson MedTech commenced U.S. launch of INHANCE INTACT, a complete instrumentation system specifically developed for subscapularis-sparing total shoulder arthroplasty. The tissue-sparing approach achieved with INHANCE INTACT instrumentation allows surgeons to perform shoulder replacement procedures with enhanced joint visualization and enables patient shoulder movement as early as day one post-op, making it well-suited for the ASC setting.

Versatile Hemiarthroplasty for the Hip

Maxx Orthopedics received FDA clearance for the Libertas Hip Portfolio, which includes Taper Reduced, Mini Taper Reduced, Coated (collared and non-collared) and Cemented Stems. Libertas Bipolar combines a cobalt-chromium outer shell with an ultra-high molecular weight polyethylene liner and a factory-assembled retention ring. Designed for use with 28mm femoral heads, the system delivers an efficient and reproducible solution for fracture management, osteonecrosis and revision hip applications.

Stable Kinematic Alignment

Medacta commenced the Japanese launch of GMK SpheriKA, reportedly the first and only knee implant optimized for kinematic alignment, following its successful introduction in Europe and the United States. Built on the clinical history of the GMK Sphere Ball-in-Socket design, GMK SpheriKA has been designed to offer patients an implant that feels natural and stable during everyday activities. It also helps surgeons accommodate a broader range of anatomies while optimizing knee function and improving overall stability, addressing some of the key limitations found in conventional knee replacement designs.

Proactively Preventing Joint Infections

Onkos Surgical received FDA 510(k) clearance for the ELEOS Proximal Tibia with NanoCept Antibacterial Technology, marking the first clearance for the technology since it was granted De Novo authorization in 2024. NanoCept fights against intraoperative bacterial contamination by targeting bacteria present in the O.R. that may settle on devices before they’re placed in patients. In preclinical studies supporting the original De Novo market authorization, NanoCept demonstrated up to a 99.999% kill rate of bacteria commonly found in the O.R.

Personalized Cementless Knee Replacement

restor3d announced the successful completion of the first clinical cases using the iTotal Identity CR 3DP Porous Fully Personalized Total Knee Replacement, the first fully personalized, cementless total knee replacement offering within the company’s Identity platform. Built on restor3d’s digital-to-implant design workflow, the system integrates CT-based planning, automated personalization and 3D-printed porous structures on all metallic components to deliver optimal fit, fixation, and function for every patient. The cementless system leverages restor3d’s proprietary TIDAL Technology on the tibia, femur and patella implants.

Advances in Total Hip Replacement

Zimmer Biomet received Japan’s Pharmaceutical and Medical Devices Agency approval for the iTaperloc Complete and iG7 Hip System, the world’s first approved orthopedic implants with Iodine Technology that inhibits bacterial adhesion on the implant surface. iTaperloc and iG7 combine the clinical heritage of the Taperloc Complete Hip System and the efficiency and performance of the G7 Acetabular System with Iodine Technology. Iodine is a biocompatible, essential body nutrient that does not cause antibiotic resistance and is commonly used in medicine as an antiseptic. Iodine Technology applies iodine to the implant’s surface during the manufacturing process to inhibit biofilm formation.

The company also received FDA 510(k) clearance to market the G7 TM Acetabular System, a next-generation implant engineered to address challenging primary and revision hip replacement surgeries.
