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, Right

Revision at a tarsal joint on the right side pertains to the cluster of articulations among the calcaneus, talus, navicular, and cuboid, an area sometimes fused or reconstructed to manage severe flatfoot deformity, arthritis, or post-traumatic instability. When hardware such as screws, plates, or a fusion cage placed at one of these joints backs out, breaks, or fails to achieve solid union, revision restores proper alignment of the hindfoot and midfoot and may involve removing broken fixation, correcting positioning, or replacing components. Given the complexity and number of individual articulations within the tarsal region, precise identification of which joint underwent the original procedure is important, and documentation should clarify whether the revision addresses malposition, mechanical complication, or displacement of previously 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: Autologous Tissue Substitute

Autologous Tissue Substitute identifies a device value where material harvested from the patient's own body, such as an autograft, is used to replace or reconstruct a body part. Its defining feature is tissue origin from the patient, setting it apart from Nonautologous Tissue Substitute, sourced from a donor or animal, and Synthetic Substitute, made of manufactured material.

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.
