Endoscopic Posterior Ankle Decompression and Release After Total Ankle Arthroplasty

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Background:

• Total ankle arthroplasty (TAA) aims to restore ankle function but can result in postoperative complications.
• Bony impingement and ankle stiffness, particularly in dorsiflexion, are common issues following TAA, even with accurate component placement.
• Persistent stiffness may necessitate surgical intervention beyond standard procedures.

Purpose of the Study:

• To describe the technical details of endoscopic posterior ankle decompression and release.
• To provide a solution for managing persistent ankle stiffness after TAA.
• To outline indications for posterior ankle decompression in TAA patients.

Main Methods:

• Endoscopic visualization of the posterior ankle.
• Decompression of the posterior ankle gutter.
• Release of the deep posterior deltoid ligament and posterior talofibular ligament.
• Management of bony impingement and soft tissue contractures.

Main Results:

• Successful decompression of the posterior ankle.
• Improved ankle dorsiflexion.
• Resolution of bony impingement symptoms.
• Minimally invasive approach with potential for faster recovery.

Conclusions:

• Endoscopic posterior ankle decompression is an effective technique for addressing persistent stiffness after TAA.
• This procedure can alleviate bony impingement and restore dorsiflexion.
• It is indicated when conservative measures and standard surgical releases fail to resolve posterior ankle restriction.
