Arthroscopic Ankle Arthrodesis

Preparation

The decision to perform ankle arthrodesis is always preceded by a detailed orthopaedic evaluation and diagnostic work-up.

The qualification process may include:

• specialist consultation,
• evaluation of joint function and stability,
• imaging diagnostics,
• assessment of the severity of degenerative changes,
• analysis of foot alignment and gait biomechanics,
• review of previous treatments and their effectiveness,
• discussion of the patient’s expectations and functional goals.

Arthroscopic ankle arthrodesis may be considered in patients whose chronic pain and joint damage significantly affect daily function, walking comfort, and lower-limb stability.

The procedure may be indicated in cases of:

• advanced ankle osteoarthritis,
• chronic pain limiting daily activities,
• ankle instability,
• post-traumatic conditions following fractures and injuries,
• deformities affecting biomechanics and limb function,
• degenerative changes resulting from previous trauma,
• overload of other foot structures caused by abnormal joint mechanics,
• failure of conservative treatment, including rehabilitation, pain management, offloading strategies, and other therapeutic approaches.

Arthroscopic ankle arthrodesis is generally not considered a first-line treatment. It is most often recommended when previous treatment methods no longer provide satisfactory improvement.

Convalescence

Recovery after arthroscopic ankle arthrodesis requires time, appropriate protection of the operated limb, and gradual rehabilitation.

During the initial recovery period, patients are typically advised to:

• walk with crutches,
• limit weight-bearing on the operated leg,
• attend regular follow-up appointments to monitor bone fusion,
• gradually increase activity according to the surgeon’s recommendations.

Rehabilitation is planned individually and focuses on improving function, restoring safe movement patterns, and helping the body adapt to the new biomechanics of the foot and ankle.

Over time, the body adapts to the altered biomechanics, while surrounding foot joints partially compensate for the loss of ankle motion.

Precautions

Advanced ankle joint degeneration tends to progress over time.

Without appropriate treatment, patients may experience:

• increasing pain,
• worsening deformity,
• declining mobility,
• overload of other foot structures,
• reduced quality of life.

Although ankle fusion can provide pain relief and improved stability, it permanently eliminates movement within the ankle joint. For this reason, qualification for surgery requires careful assessment of the patient’s joint condition, symptoms, lifestyle, and functional expectations.

Important factors considered before surgery include:

• severity of joint degeneration,
• pain intensity,
• functional limitations,
• joint alignment,
• lifestyle and individual needs,
• previous treatment history.

Surgical treatment is typically considered when pain and loss of function begin to significantly affect quality of life.

Benefits

The primary objective of arthroscopic ankle arthrodesis is to significantly reduce or completely eliminate pain.

Potential benefits include:

• reduced chronic ankle pain,
• improved limb stability,
• greater comfort while walking,
• improved confidence during movement,
• better quality of daily life,
• improved function in everyday activities,
• reduced soft tissue disruption compared with open surgery,
• improved postoperative comfort in selected patients.

The arthroscopic approach may also offer:

• small surgical incisions,
• reduced surgical trauma,
• shorter hospital stay,
• faster return to daily activities,
• lower risk of complications compared with traditional open surgery.

For many patients, the greatest benefit is the elimination of chronic pain that previously limited walking and everyday activities.

What is arthroscopic ankle arthrodesis?

Arthroscopic ankle arthrodesis is a surgical procedure designed to permanently fuse the ankle joint.

It is performed to relieve pain, improve stability, and enhance everyday function in patients with advanced ankle joint damage or chronic pain that does not respond sufficiently to conservative treatment.

How is the procedure performed?

The surgery is performed using an arthroscope, a thin camera inserted into the joint through small incisions.

During the procedure, the surgeon removes damaged joint surfaces, prepares the bones for fusion, positions the joint in optimal alignment, and stabilises the bones using implants, most commonly compression screws.

What does ankle fusion mean?

Ankle fusion means that the bones forming the ankle joint are permanently joined together.

This eliminates painful movement within the damaged joint. Although ankle motion is lost, many patients walk more comfortably and confidently after surgery because chronic pain is reduced or eliminated.

When should arthroscopic ankle arthrodesis be considered?

The procedure may be considered in cases of advanced ankle osteoarthritis, chronic pain affecting walking and daily activities, ankle instability, post-traumatic conditions, ankle deformities, and unsuccessful conservative treatment.

It is mainly intended for patients whose goal is to regain comfort, stability, and confidence while walking.

What results can be expected?

The main goal is significant pain reduction or complete pain relief.

Patients may experience improved limb stability, greater walking comfort, reduced pain, and improved quality of daily life.

Although ankle fusion eliminates movement within the joint, surrounding foot joints may partially compensate for the loss of ankle motion over time.

Why choose the arthroscopic technique?

The arthroscopic technique allows the procedure to be performed through small incisions with reduced soft tissue trauma.

Potential benefits include smaller incisions, less soft tissue disruption, shorter hospital stay, faster return to daily activities, lower risk of complications compared with traditional open surgery, and improved postoperative comfort.

Why should treatment not be delayed?

Advanced ankle degeneration may progress over time.

Without appropriate treatment, patients may experience increasing pain, worsening deformity, declining mobility, overload of other foot structures, and reduced quality of life.

In appropriately selected cases, surgery may help stop this progression and restore greater comfort in daily activities.

What does recovery involve?

Recovery requires protection of the operated limb, follow-up appointments, and gradual rehabilitation.

Patients are usually advised to walk with crutches, limit weight-bearing on the operated leg, and gradually increase activity according to the surgeon’s recommendations.

Rehabilitation is planned individually and helps the body adapt to the new biomechanics of the foot and ankle.

Is it possible to walk normally after ankle fusion?

In many cases, yes.

Although the ankle joint is permanently fused, the body gradually adapts to the new biomechanics. Neighboring joints may compensate for some of the lost movement, and many patients regain greater stability and confidence while walking than they had before surgery.

What are the indications for arthroscopic ankle arthrodesis?

The procedure may be indicated in cases of advanced ankle osteoarthritis, chronic pain limiting daily activities, ankle instability, post-traumatic changes, deformities affecting biomechanics, degenerative changes after trauma, overload of other foot structures, and failure of conservative treatment.

How is a patient qualified for surgery?

Qualification is based on a comprehensive orthopaedic assessment.

This may include specialist consultation, evaluation of joint function and stability, imaging diagnostics, assessment of degenerative changes, analysis of foot alignment and gait biomechanics, review of previous treatments, and discussion of the patient’s functional goals.

Is ankle arthrodesis a first-line treatment?

No. Arthroscopic ankle arthrodesis is generally not considered a first-line treatment.

It is most often recommended when previous treatment methods no longer provide satisfactory improvement and the main goal becomes long-term pain relief, enhanced stability, and improved quality of daily life.
