In short
Achilles debridement treats chronic Achilles tendinopathy that has not settled with non-surgical treatment. Thickened, degenerate tendon tissue and inflammation are removed so healthier tendon can heal; if a large part of the tendon is involved it may be repaired or reinforced, sometimes with a tendon transfer. It is usually a day case. You are protected in a boot or cast, move into normal shoes at 6 to 12 weeks, return to golf and gym by 8 to 12 weeks and higher-impact sport by 3 to 6 months.
- Anaesthetic
- General or regional anaesthetic
- Hospital stay
- Usually a day case
- Walking afterwards
- Limited at first, increasing in a boot
- Full recovery
- 3 to 6 months; comfort improves for up to 12 months
Why is surgery sometimes needed?
Achilles debridement surgery is used to treat chronic Achilles tendinopathy when pain persists despite non-surgical treatment. Over time, part of the tendon can become thickened, inflamed or degenerated, causing pain with walking, exercise and footwear. Debridement removes unhealthy tendon tissue and inflammation, allowing healthier tendon to heal and function more effectively.
What does the operation involve?
- The procedure is usually performed as a day case under general or regional anaesthetic
- An incision is made along or beside the Achilles tendon
- Damaged or inflamed tendon tissue is carefully debrided (removed)
- Associated problems such as inflamed bursae or bone irritation may be treated at the same time
- If a significant portion of tendon is involved, repair or reinforcement may be performed, sometimes requiring the transfer of another tendon
- The wound is closed and the ankle protected in a boot
The exact technique depends on whether the tendinopathy is mid-portion or insertional, and Prof Mason will discuss this with you beforehand.
Recovery: what to expect
0 to 2 weeks
- Your ankle is protected in a boot or cast, depending on tendon involvement
- Elevation is important to control swelling
- Weight-bearing may be limited initially
- Stitches are removed at 10 to 14 days
2 to 6 weeks
- Gradual increase in weight-bearing in the boot as advised
- Gentle ankle movement exercises may begin
- Swelling and stiffness are normal
6 to 12 weeks
- Transition from boot to normal footwear
- Physiotherapy focuses on restoring movement, strength and tendon loading
- Walking distances gradually increase
3 to 6 months and beyond
- Continued strengthening and return to low-impact exercise such as cycling or swimming
- Most patients return to golf, gym and casual hiking by 8 to 12 weeks
- Higher-impact sports by 3 to 6 months depending on comfort
- Final comfort levels may continue to improve for up to 6 to 12 months
Recovery varies with the exact procedure and with each person. You will get a plan specific to your operation.
Expected outcomes
Before surgery
- Persistent Achilles pain despite physiotherapy
- Pain with walking, running or stairs
- Stiffness, swelling or thickening of the tendon
- Reduced activity and exercise tolerance
After surgery
- Reduced pain over time
- Improved tendon comfort and strength
- Increased walking and activity tolerance
- Gradual return to exercise
Tendon healing continues for many months and physiotherapy is crucial for a good outcome. Return to sport is gradual and tailored to symptoms. Most patients achieve meaningful pain relief and improved function. Recovery time varies depending on the extent of debridement and whether additional procedures were required.
