Official Description

Arthroscopy, ankle (tibiotalar and fibulotalar joints), surgical; debridement, limited

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Surgical arthroscopy of the ankle, specifically involving the tibiotalar and fibulotalar joints, is a minimally invasive procedure that allows for direct visualization and treatment of joint conditions. The primary purpose of this procedure is to perform limited debridement, which is the removal of damaged or diseased tissue within the joint. This technique is often utilized to address issues such as arthritis, where inflammation and degeneration of the joint surfaces can lead to pain and reduced mobility. During the procedure, the patient's leg is carefully positioned to facilitate access to the ankle joint, ensuring that the knee is bent and the lower leg is free to move. This positioning is crucial for the surgeon to effectively manipulate the instruments and visualize the joint. The use of a saline solution to inflate the joint space enhances visibility and allows for a thorough inspection of the joint for any signs of injury, disease, or infection. The procedure involves creating portals for the insertion of the arthroscope and surgical tools, enabling the surgeon to remove redundant cartilage, inflamed tissue, and bone spurs, ultimately smoothing the joint surfaces and improving function. The careful execution of this procedure is essential for achieving optimal outcomes and alleviating symptoms associated with ankle joint disorders.

1. Indications

The procedure is indicated for patients experiencing conditions that affect the ankle joint, particularly those related to arthritis. The following are specific indications for performing limited debridement via arthroscopy:

  • Arthritis - Patients suffering from various forms of arthritis, which can lead to joint pain, swelling, and reduced mobility.
  • Joint Pain - Persistent pain in the ankle joint that may be due to degenerative changes or inflammation.
  • Joint Swelling - Swelling in the ankle joint that may indicate underlying pathology requiring intervention.
  • Loose Bodies - Presence of loose fragments within the joint that can cause mechanical symptoms and discomfort.

2. Procedure

The procedure involves several key steps to ensure effective debridement of the ankle joint:

  • Positioning of the Patient - The patient is positioned with the leg resting on an L-shaped bar, ensuring that the thigh is supported while the knee is bent. This positioning allows the lower leg to swing freely, providing optimal access to the ankle joint.
  • Joint Distraction - The foot is secured in a bracelet, and the ankle joint is distracted to create space for the surgical instruments and enhance visibility during the procedure.
  • Creation of Anteromedial Portal - A needle is inserted into the anteromedial aspect of the joint, and saline is injected to inflate the joint space. After inflation, the needle is withdrawn, and an anteromedial portal is created for the insertion of the arthroscope.
  • Insertion of the Arthroscope - A trocar is placed in the anteromedial portal, allowing the arthroscope to be inserted. This instrument provides a visual field for the surgeon to inspect the joint for any signs of injury, disease, or infection.
  • Creation of Anterolateral Portal - An additional portal, the anterolateral portal, is created to facilitate the use of surgical instruments during the debridement process.
  • Debridement - A motorized shaver is utilized to remove redundant cartilage, inflamed tissue, and bone spurs (osteophytes) from the joint surfaces. This step is crucial for smoothing the joint surfaces and improving overall joint function.
  • Removal of Loose Fragments - Any loose fragments within the joint are carefully removed to prevent further mechanical irritation and discomfort.
  • Flushing the Joint - The joint is flushed with saline to clear away any debris resulting from the debridement process, ensuring a clean joint environment.
  • Closure of Portals - Upon completion of the procedure, the arthroscope and surgical tools are removed, and the portal incisions are closed to promote healing.

3. Post-Procedure

After the procedure, patients may experience some swelling and discomfort in the ankle joint, which is typical following arthroscopy. Post-procedure care may include rest, ice application, and elevation of the leg to minimize swelling. Patients are often advised to follow a rehabilitation program to restore mobility and strength in the ankle. Follow-up appointments may be scheduled to monitor the healing process and assess the effectiveness of the debridement. It is important for patients to adhere to their healthcare provider's instructions regarding activity restrictions and rehabilitation exercises to ensure optimal recovery.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
