Endoscopic Flexor Hallucis Longus Transfer vs Minimally Invasive Repair in Acute Achilles Tendon Rupture
Study Details
Study Description
Brief Summary
The goal of this observational study is to compare the outcomes of two different surgical techniques (Endoscopic Flexor Hallucis Longus transfer - Group 1 vs Minimally Invasive primary repair - Group 2) for patients with acute Achilles tendon rupture. The main questions to be answered are:
-
Which group's patients are more satisfied?
-
Which group's patients appear to have a greater complication rate?
-
Which group's patients have greater calf and ankle circumference compared to the unaffected limb?
-
Which group's patients have greater passive and active range of ankle motion compared to the unaffected limb?
-
Are group 1 patients characterized by strength deficit in hallux flexion power?

Detailed Description
Two separate foot and ankle surgeons in Northern Greece prefer to use a different surgical technique in their respective patients with Acute Achilles tendon rupture.
The first one (A.E.) prefers to perform only Endoscopic Flexor Hallucis Longus transfer, while the second one (P.S.) prefers to perform only Minimally invasive primary repair assisted by the Achillon device (Percutaneous Achilles Repair System - PARS). They both agreed to enroll their recently operated patients (last 5 years) in this retrospective study, which will be conducted by the researcher (M.K.). The patient's study may be retrospective, nevertheless, the patients were randomly chosen and enrolled by a prospectively designed study protocol. Each surgeon applied the respective surgical treatment modality regardless of each patient's characteristics, biometrics, or comorbidities. Inclusion and Elimination criteria will be applied. The patient's satisfaction will be evaluated with the Achilles Tendon Total Rupture Score (ATRS). Complications will be documented. Calf and ankle circumference will be measured and compared to the contralateral healthy limb. Ankle passive and active range of motion will be measured and compared to the contralateral healthy limb. Possible correlations will be investigated regarding patient age, BMI, history of smoking, level of activity, and comorbidities.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Endoscopic Flexor Hallucis Longus transfer / Group 1 Patients with acute Achilles tendon rupture managed with Endoscopic Flexor Hallucis Longus transfer by one surgeon (A.E.) in one hospital (General Hospital of Naoussa, Naoussa, Greece), all of which followed the same rehabilitation protocol. |
Procedure: Surgery for the treatment of Acute Achilles tendon rupture
Two different surgical techniques were applied in two different patient groups for the same disease. Their outcomes are evaluated and compared
|
| Minimally Invasive Primary repair / Group 2 Patients with acute Achilles tendon rupture managed with Minimally Invasive Primary repair by one surgeon (P.S.) in one hospital (St. Luke's Hospital, Thessaloniki, Greece), all of which followed the same rehabilitation protocol. |

Outcome Measures
Primary Outcome Measures
- Patient Satisfaction assessed with the Achilles Tendon Total Rupture Score [More than 12 months postoperatively]
Evaluated and quantified with the Achilles Tendon Total Rupture Score (minimum value = 0 - worst outcome, maximal value = 100 - best outcome)
Secondary Outcome Measures
- Complication Rate [More than 12 months postoperatively]
Complications will be recorded and categorized: Rerupture, Infection, Nerve injury, Miscellaneous
- Calf Circumference [More than 12 months postoperatively]
Calf circumference measured 15 cm distally to the inferior pole of the patella. Contralateral limb calf circumference will also be measured. The Calf Circumference Difference will be calculated and compared between the two groups.
- Ankle Circumference [More than 12 months postoperatively]
Ankle circumference measured 8 cm proximally to the lateral malleolus. Contralateral limb ankle circumference will also be measured. The Ankle Circumference Difference will be calculated and compared between the two groups.
- Ankle joint Range of Motion [More than 12 months postoperatively]
Active and Passive Ankle joint Range of Motion will be calculated with an electronic goniometer. Contralateral limb Range of Ankle joint Motion will also be measured. The Range of Motion Difference will be calculated and compared between the two groups.
