Background:The optimal treatment of acute Achilles tendon ruptures remains
controversial. When surgical repair is undertaken, the reported rate of
infections and wound-healing complications ranges from 2% to 5%.
Meta-analyses have demonstrated that minimally invasive approaches have
equivalent rerupture rates, a significantly lower risk of superficial
infections, and higher patient satisfaction rates compared with traditional
open Achilles repair techniques.Purpose:To review the clinical outcomes of acute, limited open Achilles tendon repair
using modified ring forceps and to analyze functional results using foot and
ankle–specific outcome measures.Study Design:Case series; Level of evidence, 4.Methods:The clinical records of 32 consecutive patients (mean age, 44 years) with 33
acute Achilles tendon ruptures were retrospectively reviewed. All patients
underwent limited open repair with modified ring forceps through a 2- to
3-cm midline incision. Suture placement into the tendon stumps was guided
using a pair of ring forceps bent 30°. Three No. 2 nonabsorbable sutures
were placed in the proximal and distal segments, the tendon ends were
reapproximated, and the sutures were tied to secure the tendon. Outcomes
from a 10-cm visual analog scale (VAS), the Foot and Ankle Ability Measure
(FAAM), and the Victorian Institute of Sport Assessment–Achilles (VISA-A)
were assessed.Results:At final follow-up (mean, 42.1 months [range, 6-90 months]), 31 of 32
patients (33 Achilles tendons) reported no pain in their Achilles, with a
mean Achilles VAS score of 0.7 ± 4.2 of 100. The mean postoperative VISA-A
score was 82.3 ± 19.5 of 100. The mean FAAM activities of daily living and
sports subscores were 96.5% ± 5.2% and 85.1% ± 21.2%, respectively.
Regarding current functional level, 19 of 33 tendons (57.6%) were rated as
“normal,” 10 (30.3%) as “nearly normal,” and 4 (12.1%) as “abnormal”; none
were rated as “severely abnormal.” There was 1 case (3.0%) of a superficial
infection; there were no cases of deep infections, sural neuritis, or
reruptures. The cost of the modified ring forceps technique is 5.3 to 12.1
times less than commercially available devices.Conclusion:Limited open Achilles repair with modified ring forceps provides an
economical repair with excellent pain relief, favorable functional outcomes,
and a very low complication rate at midterm follow-up.
