K910992 is an FDA 510(k) clearance for the AMK TOTAL KNEE SYSTEM W/DU PONT ENHANCED UHMWPE. Classified as Prosthesis, Knee, Patellofemorotibial, Semi-constrained, Cemented, Polymer/metal/polymer (product code JWH), Class II - Special Controls.

Submitted by Depuy, Inc. (Warsaw, US). The FDA issued a Cleared decision on August 10, 1992 after a review of 522 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Orthopedic FDA review panel, regulated under 21 CFR 888.3560 - 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.
