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

Ankle Joint, Right

Revision at the right ankle joint addresses problems with a previously placed device or graft, most often a total ankle arthroplasty component that has loosened, subsided into the talus or tibia, become infected, or worn unevenly under the biomechanical stresses of ambulation. Because the ankle mortise is a tightly constrained hinge formed by the tibia, fibula, and talus, малейшее malalignment or bone loss around an implant can cause pain, instability, or impingement, so revision surgery frequently involves removing polyethylene inserts, exchanging metal components, or grafting bone defects before reseating hardware. Documentation should specify whether the correction involves adjusting the position of an existing device, replacing a component outright with new hardware, or removing material without replacement, since each corresponds to a different qualifier and reflects a distinct amount of reconstructive work at this weight-bearing joint.

Approach: Percutaneous Endoscopic

Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.

Device: Infusion Device

Infusion Device denotes a device left in place to deliver medication, fluids, or other substances into a body part over time, such as an intrathecal or epidural pump. It is distinct from devices that merely monitor or mechanically support tissue, since its function is ongoing pharmacologic or fluid delivery rather than structural replacement. Common placements include the spinal canal, peritoneal cavity, and vascular access sites.

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.
