Intended Use

The Stryker Global Modular Replacement System, Modular Replacement System and Modular Rotating Hinge Knee Component are sterile, single-use devices intended for use in situations where there is a need for replacement of bone due to radical bone loss. This loss can be related to oncology, trauma or failed previous prosthesis. Specific Indications for Use are listed below.

Device Story

Modular orthopedic system for extensive bone reconstruction of femur and proximal tibia; used in oncology, trauma, and revision arthroplasty. Components include stemmed femoral/tibial parts, intercalary segments, and rotating hinge knee assembly (bushings/axle). Used in clinical/surgical settings by orthopedic surgeons. Devices replace diseased or damaged bone segments to restore limb function. System is modular, allowing surgeon to assemble components intraoperatively to match patient anatomy. Output is a structural prosthetic replacement. Benefits include limb salvage and restoration of joint stability in cases of severe bone loss.

Clinical Evidence

No clinical data required or provided. Substantial equivalence is based on identical technological characteristics and design to the predicate device.

Technological Characteristics

Modular orthopedic prosthesis system. Materials and design are identical to predicate. Components include stemmed femoral/tibial segments, intercalary pieces, and rotating hinge knee assembly. Sterile, single-use. Intended for use with bone cement (for specific components).

Indications for Use

Indicated for patients requiring extensive reconstruction of femur/proximal tibia due to radical bone loss from oncology (tumor resection), acute trauma, or revision of failed arthroplasty. Includes limb salvage procedures, prosthetic knee fusion, and total femoral replacement. Contraindications not explicitly listed beyond general device labeling updates.

Regulatory Classification

Identification

A hip joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a hip 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 an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).

Dear Julia Bally:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

# Additional Predicate Device Used to Support Substantial Equivalence:

# Reason for 510(k) Submission:

The purpose of this "Change Being Effected" bundled submission is to add a contraindication to the labeling of the subject Global Modular Replacement System, Modular Replacement System, and Modular Rotating Hinge Knee Component. Additionally, MRI Safety information is being updated to align with the example labeling provided in the FDA guidance document "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment" (dated October 10, 2023), and clerical updates are also being made to the IFUs.

# Device Description:

The Global Modular Replacement System (GMRS) is comprised of a number of components that are intended to be used in conjunction with each other, or in conjunction with components of the Modular Replacement System (MRS) or the Modular Rotating Hinge Knee System (MRH). The Modular Rotating Hinge Knee System is a tricompartmental knee system. The system consists of a stemmed femoral component and a stemmed tibial bearing component connected by a set of bushings and an axle. The MRH Tibial Rotating component is a part of the MRH system and mates with the GMRS Standard Proximal Tibia. These devices are intended to be used in clinical situations where there is radical bone loss of the femur and/or proximal tibia. This radical bone loss can be related to oncology (tumor), trauma or failed previous prosthesis.

#### Intended Use:

The Stryker Global Modular Replacement System, Modular Replacement System and Modular Rotating Hinge Knee Component are sterile, single-use devices

intended for use in situations where there is a need for replacement of bone due to radical bone
