Clinical Effect of Endoscopic Surgery for Delayed Wound Healing After Achilles Tendon Suture

This study proposes endoscopic surgery for delayed wound healing after Achilles tendon suture which is a brand new treatment，and retrospectively analyzed the clinical data of 4 cases treated with this treatment. The analysis results of the clinical efficacy of the method can serve as a reference for clinical and surgical decision-making and prognosis assessment.

Study Overview

• Status: Completed
• Conditions: Wound Healing
• Intervention / Treatment: Other: Self-control

Detailed Description

Background: Delayed wound healing is a kind of postoperative complication of Achilles tendon suture. Conventional surgical approach is open surgery in order to clean the wound, which requires multiple dressing changes and involves a longer recovery period. We recently developed arthroscopic surgery for delayed wound healing after Achilles tendon suture. This therapy may be an alternative approach to open surgery.

Purposes: In this paper we evaluate the long-term efficacy of endoscopic surgery for delayed wound healing after Achilles tendon suture.

Patients and Methods: Clinical data of 4 patients with delayed wound healing after Achilles tendon suture who underwent endoscopic surgery from April 2008 to October 2017 at our institute were retrospectively analyzed. There were 3 males and 1 females with age of 39-60 years, the follow-up period was 8-43 months). All the patients had unilateral tendon rupture with 3 cases on the left and 1 cases on the right. Scores on Visual analogue scale(VAS) and the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale were used. The postoperative outcome was evaluated on the basis of Victorian Institute of Sport Assessment-Achilles score and Achilles tendon total rupture score (ATRS).

Study Population

4 patients with delayed healing after Achilles tendon suture surgery who were treated at our institution, in the period from April 2008 to July 2019. The patients were 3 men and 1 woman, aged 39 to 60 years. Among them, 3 had surgery on the left Achilles tendon and 1 had surgery on the right Achilles tendon. The time from the first operation (Achilles tendon suture) to foreign body reaction ranged from 1 month to 5 months.

Description

Inclusion Criteria:

• The diagnostic criteria for delayed wound healing after Achilles tendon suture are met, namely the presence of skin necrosis, wound nonunion, or delayed wound healing.

Exclusion Criteria:

• The expected healing time of wounds with regular dressing changes is <2 weeks.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Visual Analogue Scale	Use Visual Analog Scale(VAS) to evaluate the pain recovery of patients who received endoscopic surgery. VAS ranges from 0 to 10, higher scores mean a worse outcome.	8 months to 4 years after the surgery
American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Score	Use American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Score(AOFAS) to evaluate the function recovery of patients who received endoscopic surgery. AOFAS ranges from 0 to 100, higher scores mean a better outcome.	8 months to 4 years after the surgery
Victorian Institute of Sport Assessment-Achilles	Use Victorian Institute of Sport Assessment-Achilles(VISA-A) to evaluate the pain and movement recovery of patients who received endoscopic surgery. VISA-A ranges from 0 to 100, higher scores mean a better outcome.	8 months to 4 years after the surgery
Achilles tendon total rupture score	Use Achilles tendon total rupture score(ATRS) to evaluate the function and movement recovery of patients who received endoscopic surgery. VISA-A ranges from 0 to 100, higher scores mean a better outcome.	8 months to 4 years after the surgery
Tegner knee motion score	Use Tegner knee motion score to evaluate the sports ability of patients who received endoscopic surgery. Tegner knee motion score ranges from 0 to 10, higher scores mean a better outcome.	8 months to 4 years after the surgery
