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: 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: 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.
