Device Story

Smith & Nephew knee systems (total, unicompartmental, patello-femoral, hinge) are orthopedic implants used in primary and revision knee arthroplasty. These devices replace damaged joint surfaces to restore function and reduce pain. Implants are surgically placed by orthopedic surgeons in hospital or surgical center settings. This submission updates labeling to include Magnetic Resonance (MR) safety information. No changes were made to device design, materials, manufacturing, or sterilization. The update ensures clinicians have appropriate MR safety parameters for patients with these implants. Benefits include continued clinical utility of existing knee systems with clarified MR compatibility, facilitating safe diagnostic imaging for patients.

Clinical Evidence

No clinical data provided. Substantial equivalence is supported by bench testing for MR safety, including magnetically induced displacement force (ASTM F2052), torque (ASTM F2213), RF-induced heating (ASTM F2182-19e2, IEC 60601-2-33, ISO/TS 10974:2018E), and MR image artifact (ASTM F2119).

Technological Characteristics

Orthopedic knee implants (total, unicompartmental, hinge, patello-femoral). Materials and design are identical to previously cleared predicates. MR safety testing conducted per ASTM F2052, ASTM F2213, ASTM F2182-19e2, and ASTM F2119. Sterilization and manufacturing processes remain unchanged.

Indications for Use

Indicated for patients with rheumatoid arthritis, post-traumatic arthritis, osteoarthritis, degenerative arthritis, failed osteotomies, failed unicompartmental or total knee replacement, functional deformity, or fractures unmanageable by other techniques. Specific systems indicated for primary/revision surgery where cruciate/collateral ligaments are incompetent or absent. Patello-femoral system indicated for degenerative arthritis in distal femur/patella, patellar dislocation/fracture, or failed previous surgery.

Regulatory Classification

Identification

A knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a knee joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a tibial component or components and a retropatellar resurfacing component made of ultra-high molecular weight polyethylene. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).

The technological characteristics, function of the devices, packaging and sterilization remain unchanged. As these products have been in distribution for several years, some parts have undergone changes in the technological characteristics that were assessed in compliance with the FDA's guidanceon "Deciding When to Submit a 510(k) for a Change to an Existing Device" or the FDA predecessor guidance on how to review changes to an existing device. These are not cumulative changes for all Smith & Nephew Knee Systems, but are rather specific changes that only affect certain parts. In the context of this submission, no modifications have been made to the device design, materials, sterilization, or the manufacturing process of the previously cleared devices due to the addition of MR Labeling for this 510(k). # Indications for Use # Legion Hinge - 1.

Magnetically induced displacement force (ASTM F2052) - 2. Magnetically induced torque (ASTM F2213) - 3. Radiofrequency (RF) induced heating (ASTM F2182-19e2, IEC 60601-2-33, ISO/TS 10974:2018E) - 4. MR image artifact (ASTM F2119) MR Safety testing/ assessments support the appropriate MR parameters and symbols found in the subject device labeling. As these products have been in distribution for several years, bacterial endotoxin testing was completed in previous submissions. The addition of the MR safety information to thelabeling does not affect the pyrogenicity, therefore, the subject Smith & Knee Systems are still expected to met the acceptable endotoxin limits as stated in the FDA Guidance, "Submission and Review of Sterility Information in Premarket Notification (510(k)) Submissions for Devices Labeled as Sterile," "Pyrogen and Endotoxins Testing: Questions and Answers," and ANSI/AAMI ST72. {23}------------------------------------------------ # Substantial Equivalence Information The subject Smith & Nephew Knee Systems are identical in design, technological characteristics, function of the devices, packaging and sterilization to the commercially available predicate devices, including substantially equivalent letter to file parts, listed in Table 6.1 below. | Manufacturer | Description | Submission<br>Number | Clearance<br>Date | |----------------------|----------------------------------------------------|------------------------------------------|------------------------------------------------------| | Smith & Nephew,Inc. | ANTHEM Total Knee System | K142807<br>K170648 | 12/22/2014<br>05/11/2017 | | Smith & Nephew,Inc. | Genesis Uni Knee System | K030301<br>K912735 | 02/25/2003<br>12/27/1991 | | Smith & Nephew,Inc. | JOURNEY BCS and II Knee<br>Systems | K042515<br>K111711<br>K140555 | 03/14/2005<br>09/16/2011<br>05/29/2014 | | Smith & Nephew,Inc. | JOURNEY II CR Knee System | K113482<br>K121443 | 02/27/2012<br>08/13/2012 | | Smith & Nephew,Inc. | JOURNEY II Uni Knee System | K152315 | 10/28/2015 | | Smith & Nephew, Inc. | JOURNEY II UK Knee System | K190085 | 2/11/2019 | | Smith & Nephew,Inc. | JOURNEY II XR Bi-Cruciate<br>Retaining Knee System | K152726 | 10/21/2015 | | Smith & Nephew,Inc. | JOURNEY PFJ System | K051086 | 05/31/2005 | | Smith & Nephew,Inc. | JOURNEY Uni Knee System | K061011<br>K061779<br>K073175<br>K102069 | 07/11/2006<br>08/04/2006<br>12/20/2007<br>10/05/2010 | | Smith & Nephew, Inc. | Legion Hinge Total Knee System | K151118<br>K081111 | 07/28/2015<br>07/23/2008 | {24}------------------------------------------------ | Manufacturer | Description | Submission<br>Number | Clearance<br>Date | |----------------------|------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------| | Smith & Nephew,Inc. | Legion Total Knee System | K041106<br>K043440<br>K060742<br>K071071<br>K072531<br>K073325<br>K091543<br>K100897<br>K112941<br>K162775<br>K180334 | 07/01/2004<br>02/18/2005<br>05/03/2006<br>09/19/2007<br>12/06/2007<br>12/20/2007<br>12/21/2009<br>05/13/2010<br>12/20/2011<br>01/13/2017<br>03/05/2018 | | Smith & Nephew,Inc. | ZUK Unicompartmental Knee<br>System | K033363<br>K122529 | 01/16/2004<br>11/16/2012 | | Smith & Nephew, Inc. | ENGAGE Partial Knee System | K190439 | 11/21/2019 | | Smith & Nephew, Inc. | Porous Patella and Porous Tibial<br>Baseplates | K211221 | 10/01/2021 | # Conclusion In summary, the only differences between the subject devices, including substantially equivalent letter to file catalog items and the commercially available predicate devices were supporting MR safety testing/assessment and the addition of MR safety information to the labeling. These differences are not critical to the intended therapeutic, diagnostic, prosthetic, or surgical use of the subject devices. The subject Smith & Nephew Knee Systems are identical in function, design features, materials, sterilization, manufacturing methods and operational principles to what was previously 510(k) cleared and do not affect the safety and effectiveness of the subject devices when used as labeled. Due to the supporting documentation within this filing, it is conducted that the subject device(s) are substantially equivalent to the predicate device(s).
