Arthroscopic Debridement After Total Ankle Arthroplasty

Area of Science:

• Orthopedic surgery
• Foot and ankle reconstruction
• Minimally invasive procedures

Background:

• Residual pain after total ankle arthroplasty (TAA) is often due to impingement.
• Literature on arthroscopic debridement for post-TAA impingement is limited.
• This study investigates arthroscopic debridement for TAA patients with impingement pain.

Purpose of the Study:

• To evaluate the effectiveness of arthroscopic debridement in managing residual impingement pain after TAA.
• To assess the impact of arthroscopic debridement on pain and range of motion in TAA patients.

Main Methods:

• A case series of 12 patients who underwent arthroscopic debridement for post-TAA impingement pain.
• Patients were evaluated via chart review, clinical examination, and radiologic assessment.
• Average follow-up was 58.8 months, with debridement occurring an average of 38.2 months post-TAA.

Main Results:

• The median AOFAS hindfoot score improved significantly from 64.6 to 73.5 post-procedure (P < .05).
• Good pain relief was reported by 8 patients; partial relief by 4.
• Three patients with painful ankylosis experienced no improvement in range of motion.

Conclusions:

• Arthroscopic debridement is effective for residual impingement pain post-TAA in most cases (8/12) at 2-year follow-up.
• For painful ankylosis, arthroscopic debridement offers only partial pain relief and does not enhance range of motion.
