The document describes a knee replacement system and its components, focusing on mechanical testing and equivalence to predicate devices. There is no mention of AI or ML in the intended use, device description, or performance studies.
Yes.
The device is a knee replacement system intended to treat painful and disabling joint diseases, restore knee joint configuration and function, correct deformities, and address failed previous procedures, which clearly falls under the definition of a therapeutic device.
No
The device description and intended use indicate that the LOSPA II Knee System (EXULT Knee Replacement System) is a knee replacement system used for the treatment of diseases and conditions affecting the knee, such as arthritis and deformities. It is a therapy device, not a diagnostic device.
No
The device description explicitly states that the additional components are "Femoral Components and Instrumentation system," which are physical hardware components for knee replacement surgery.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This testing is done outside of the body.
- Device Description and Intended Use: The description clearly states that the LOSPA II Knee System is a knee replacement system, consisting of femoral components and instrumentation. Its intended use is for the surgical treatment of knee joint diseases and deformities. This is a device that is implanted within the body.
Therefore, based on the provided information, the LOSPA II Knee System is a surgical implant, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use

- Revised Size 12 PS, CR Femoral Component -
- Additional Size 13 PS, CR Femoral Component -
- -Instrumentation
The subject LOSPA II Knee System (EXULT Knee Replacement System) components specification inclusions are a line extension of Femoral Components and Instrumentation system. The following are the additional components,
A) LOSPA II Femoral Component (PS-type and CR-type)
Femoral Components of LOSPA II Knee System (EXULT Knee Replacement System) are designed based on Femoral Components of LOSPA II Knee System. Femoral component has two different types which match to Tibial Insert types: PS-type and CR-type. There is one additional size, #13 of each design (CR and PS), each for left and right sides, and one modified size #12 (CR and PS, each left and right). For both CR and PS designs, the ranges of dimensions are the same. All femoral components are manufactured from cobalt-chromium-molybdenum alloy conforming to ASTM F75. Standard Specification for Cobalt-28 Chromium-6 Molybdenum Alloy Castings and Casting Alloy for Surgical Implants (UNS R30075)
B) Instrumentation
There are additional instruments for use with the system implant components.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The LOSPA II Knee System (EXULT Knee Replacement System) additional components were justified by a series of testing requirements conducted on the worst-case predicate components of the system to demonstrate substantial equivalence and included methods described in the following standards: ASTM F1800: ASTM F1223; ASTM F2083: ASTM F1814, ISO 14243 and ISO 21536, which consisted of tibial plate fatigue testing, constraint testing, contact analysis, insert disassembly testing, tibial insert post shear testing, wear testing, dislocation/jump distance and range of motion. Mechanical testing of the additional components was not necessary as the minor size changes are consistent with the previously evaluated predicate device components.

§ 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.
