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: Percutaneous

Percutaneous describes entry by needle or instrument puncture through the skin or mucous membrane to reach the site of the procedure, without cutting the tissue open or using a visualizing scope. It differs from Open in that the site itself is never exposed, and from Percutaneous Endoscopic in that no endoscope is used to see internal structures. Common examples include needle biopsies and injections.

Device: External Fixation Device

This is the general external fixation device value, used when pins or wires anchored in bone are connected to a stabilizing frame outside the body to hold a fracture or joint in position, without specifying a more particular frame configuration. It contrasts with the more specific External Fixation Device subtypes - Monoplanar, Ring, Hybrid, and Limb Lengthening - which describe the frame's geometry or added lengthening function.

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.
