FDA PRODUCT CODE · CLASS II
OIY — Prosthesis, Knee, Patellofemorotibial, Semi-Constrained, Cemented, Polymer + Additive/Metal/Polymer + Additive
Indicated for: 1. Painful and disabled knee joint resulting from osteoarthritis, rheumatoid arthritis, traumatic arthritis where one or more compartments are involved. 2. Correction of varus, valgus, or posttraumatic deformity. 3. Correction or revision of unsuccessful osteotomy, arthrodesis, or failure of previous joint replacement procedure. For cemented use.
What these counts are not
Clearance and recall counts are SPEQ’s aggregation of FDA’s own published records for the code. A recall count is a measure of history, not of a device’s safety, neither number is an FDA rating, and SPEQ is not affiliated with the FDA.
What this classification requires
Every statement below is FDA’s own classification record for this product code, quoted from the device classification field reference. The SPEQ reading beneath each one is SPEQ’s interpretation of what it means for the work, and is not FDA text.
510(K)
SPEQ READINGA premarket notification under 21 CFR Part 807 Subpart E is the route for this code. The submission argues substantial equivalence to a legally marketed predicate, so the engineering question is which predicate the design can actually be compared against, and the evidence question is what testing supports that comparison.
Class II (moderate to high risk): general controls and special controls
SPEQ READINGSpecial controls are the distinguishing feature: performance standards, guidance documents, patient registries or postmarket surveillance named for the device type. Find the special controls before designing the test plan — they usually name the tests.
Device is eligible for The Voluntary Malfunction Summary Reporting Program
SPEQ READINGMalfunctions for this code may be reported in periodic summary form rather than as individual MDRs under 21 CFR Part 803. Eligibility is a property of the product code; using it is a decision the manufacturer makes and must be able to justify.
Not exempt due to Good Manufacturing Practice (GMP)/Quality System
SPEQ READINGThe full Quality Management System Regulation (21 CFR 820, incorporating ISO 13485:2016) applies, and is what an FDA inspection of this device will be conducted against.
Device is implantable
SPEQ READINGImplant status raises the evidentiary bar on biocompatibility and on traceability from finished device back to material lot.
Device is not used for life sustaining purposes
SPEQ READINGNo life-sustaining designation attaches to this code.
Device is not a candidate for a third party review program
SPEQ READINGFDA reviews any premarket notification for this code directly.
Other product codes under 21 CFR 888.3560
One regulation usually governs several product codes. These share this code’s regulation, and therefore its classification basis.
21 CFR 888.3560 — Knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis
The classification regulation for this product code, as published by the Office of the Federal Register. This is the regulation text itself — no SPEQ interpretation appears in it.
(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.

The labeling is missing the size/diameter information.
Potential for delay in surgery and/or ball bearings to be left in the wound. Repeated cycles of sonic cleaning can break down the ball bearing retention feature (swage) on the shim. To prevent this, TASP shims must be manually cleaned and inspected per product insert, 87-6203-991-22.
