(654 days)
No
The document describes a physical medical device (a knee spacer) made of bone cement and does not mention any software, algorithms, or data processing that would indicate the use of AI or ML.
Yes
The device is used as an adjunct in total knee replacement for septic processes, implying a therapeutic purpose to aid in recovery or treatment of the infection and subsequently the knee replacement.
No
Explanation: The device, Spacer-K, is described as a temporary knee prosthesis used as an adjunct in total knee replacement for septic processes. Its function is to mimic a total knee prosthesis, not to diagnose a condition.
No
The device description explicitly states that the device is a physical, two-component implant made of gentamicin/polymethylmethacrylate bone cement.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Spacer-K Function: The description clearly states that Spacer-K is a temporary implantable device used in the body during a surgical procedure (total knee replacement). It mimics a knee prosthesis and is made of bone cement.
The intended use and device description are entirely focused on an implantable surgical device, not a device used to test samples outside the body.
N/A
Intended Use / Indications for Use
Spacer-K is indicated for temporary use (maximum 180 days) as an adjunct in total knee replacement (TKR) in skeletally mature patients undergoing a two-stage procedure due to a septic process. Spacer-K is only indicated for an implantation period of 180 days or less. Because of the inherent mechanical limitations of the device material (gentamicin/polymethilmethacrylate), Spacer-K is only indicated for patients who will consistently use traditional mobility assist devices (e.g. crutches, walkers, canes ) throughout the implantation period.

§ 888.3560 Knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis.
(a)
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).(b)
Classification. Class II.

DEVICE DESCRIPTION
The Spacer-K is a temporary device that mimics a "total knee prosthesis". The two-component unconstrained design incorporates a femur and tibial component, it's fully formed by gentamicin/polymethyImethacrylate (PMMA) bone cement.
INDICATIONS FOR USE
Spacer-K is indicated for temporary use (maximum 180 days) as an adjunct in total knee replacement (TKR) in skeletally mature patients undergoing a two-stage procedure due to a septic proccss. Spacer-K is only indicated for an implantation period of 180 days or less. Because of the inherent mechanical limitations of the device material (gentamicin/polymethilmethacrylate), Spacer-K is only indicated for patients who will consistently use traditional mobility assist devices (e.g. crutches, walkers, canes ) throughout the implantation period.
SUBSTANTIAL EQUIVALENCE:
The modified Spacer-K device has the same design, incorporates the same materials, has equivalent performance and mechanical characteristics, and has the same shelf and packaging as the predicate Spacer-K device (K032522). Additionally, the modified Spacer-K device has a similar gentamicin release profile as that of the predicate Biomet Stage One Disposable Cement Spacer Mold for Temporary Knee Prosthesis with Reinforcement Stem (K050210) when used with predicate Biomet Cobalt G HV Bone Cement (K051532).

Dear Mr. Sarabia:
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 (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. 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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
