Outcomes and Complications of Endoscopically-assisted Percutaneous Achilles Tendon Repair

      Introduction

      Open repair of acute Achilles tendon rupture is considered as a standard surgical treatment while percutaneous technique has gained increasing popularity especially under endoscopic control. However, there is a lack of currently research reporting outcomes and complications following this technique.

      Methods

      A retrospective chart reviews with prospectively collecting data were performed in 30 patients with 30 legs who underwent endoscopically-assisted percutaneous Achilles tendon repair using 6-portal technique between 2008 and 2015. The minimum follow up to be included in the study was 6 months (mean, 49.3 months; range, 6 to 76 months). The primary outcome was FAAM, SF-36, and VAS. The secondary outcomes included operative time, recovery time, and complications.

      Results

      There were 30 patients (24 male and 6 female) with mean age of 36.7 years. An average of tourniquet time was 39.6 minutes (range, 23-67 minutes). There was significant improvement of VAS (7.1/10 to 0.1/10), SF-36 (PCS (38.8 to 49.9) and MCS (49.0 to 51.8)), FAAM (Activity, 19.0 to 88.4 and Sport, 0 to 65.6). An average time to return to activity of daily living, work, and sports were 6 weeks, 7 weeks, 3.6 months respectively. The complications included hypertrophic scar without pain (6.7%), superficial wound infection (3%). There was no re-rupture, deep vein thrombosis, sural nerve injury, and painful scar in this study.

      Conclusion

      Endoscopically assisted percutaneous Achilles tendon repair demonstrated significant improvement in terms of functional outcomes as measured with the FAAM, SF-36, and VAS. This technique is safe and feasible for treatment patients with acute rupture of Achilles tendon.
