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
Tarsometatarsal Joint, Left
Revision of the left tarsometatarsal joint corrects a prior surgical outcome at the Lisfranc complex, where the midfoot bones articulate with the metatarsal bases, an area often stabilized surgically after fracture-dislocation or progressive arthritic collapse. The considerable mechanical demand placed on this junction during push-off can cause fixation hardware to loosen or fracture, or fusion attempts to fail to consolidate, leading to persistent pain and midfoot instability that revision surgery aims to resolve through repositioning, replacing, or removing the previously placed material. Precise documentation of the type of correction performed, whether adjusting an existing device, substituting new hardware, or removing malfunctioning components, is essential given the load-bearing role of this joint in normal foot mechanics.
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: 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.
