K945028 is an FDA 510(k) clearance for the FINN KNEE SYSTEM. Classified as Prosthesis, Knee, Femorotibial, Constrained, Cemented, Metal/polymer (product code KRO), Class II - Special Controls.

Submitted by Biomet, Inc. (Warsaw, US). The FDA issued a Cleared decision on February 14, 1996 after a review of 489 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Orthopedic FDA review panel, regulated under 21 CFR 888.3510 - the FDA orthopedic device regulatory framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Orthopedic submissions.
