Operation Definition

Correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device

Procedure Overview

Revision procedures correct a malfunctioning device already implanted in a lower joint, or reposition a device that has shifted out of place, without necessarily removing and replacing the whole implant. Examples include tightening a loosened hip component, adjusting a worn knee liner, or repositioning a dislocated joint implant back into alignment. The reason for surgery is a problem with hardware from an earlier operation rather than new injury to native tissue.

These procedures are often needed years after an initial joint replacement, as components can loosen, wear, or shift with normal use. Surgeons aim to fix the specific mechanical problem while preserving as much of the existing implant and surrounding bone as possible, since more extensive revisions carry greater surgical risk and longer recovery.

Anatomy & Axis Detail

Tarsal Joint, Left

Revision of a left tarsal joint involves correcting a prior surgical intervention within the hindfoot or midfoot complex formed by the talus, calcaneus, navicular, and cuboid bones, an area frequently treated surgically for collapsing flatfoot, arthritic pain, or nonunion following fusion. Because these joints bear substantial load transfer between the ankle and forefoot, failed hardware or a pseudarthrosis at a fusion site can cause persistent pain and deformity, requiring the surgeon to remove or reposition fixation, exchange failed components, or address bone healing problems directly. Since the tarsal region encompasses several distinct articulations, the documentation should make clear exactly which joint's earlier procedure is being revised and whether the intervention constitutes correction, replacement, or removal of the implanted material.

Approach: External

External approach applies to procedures performed directly on the skin or mucous membrane, or on an accessible body surface, without any instrumentation passing through a puncture or orifice. It covers things like manual reduction of a fracture or excision of a skin lesion. It differs from Via Natural or Artificial Opening in that no internal passage is entered at all, only the exposed surface.

Device: Internal Fixation Device

Internal fixation device is the general value for hardware such as plates, screws, or rods placed within the body to stabilize bone or joint, used when a more specific configuration is not indicated. It stands in contrast to the named subtypes - Rigid Plate, Intramedullary, Sustained Compression, and Intramedullary Limb Lengthening - which specify how the hardware achieves stabilization.

Coding & Documentation

Documentation needs to identify that an existing device was the target of correction, whether through repositioning, adjustment, or partial component exchange, and that the fix did not amount to a full swap of the entire prosthesis. Notes describing loosening, malposition, or component wear typically support Revision. A common error arises when a full component exchange occurs during a documented revision surgery; if the entire device is replaced, the correct root operation is Replacement, even though the surgeon may call it revision arthroplasty.

Commonly Confused With

ReplacementRevision is most commonly confused with Replacement because both terms appear in the context of a failed prior implant; the difference is whether the existing device is corrected or repositioned versus entirely exchanged.
RemovalIt can also be confused with Removal, since Removal alone takes hardware out without correcting malfunction or reinserting anything in its place.
