Abstract
Background:
Roughly 30% of patients with chronic lateral ankle instability (CLAI) have
long-lasting painful instability requiring surgical intervention. Ligament
reconstruction with the traditional open method and using tendon allografts
can provide sufficient mechanical stability for severe CLAI. Arthroscopic
ligament reconstruction with tendon allograft has recently been introduced
to treat CLAI.
Purpose:
In this study, we describe an arthroscopic ligament reconstruction procedure
involving the use of the tendon allograft for patients with CLAI, and we
compare the efficacy of this procedure with open ligament reconstruction
with tendon allograft.
Study Design:
Cohort study; Level of evidence, 3.
Methods:
We enrolled 10 patients (4 men and 6 women) with CLAI (mean age, 37.3 years;
range, 16-57 years) who underwent arthroscopic ligament reconstruction with
tendon allografting between November 2017 and June 2019. The control group
consisted of 10 patients who received open tendon allograft reconstruction.
Preoperative and 2-year postoperative functional outcomes were evaluated
using the American Orthopaedic Foot & Ankle Society ankle-hindfoot scale
(AOFAS), Karlsson Ankle Functional Score (KAFS), pain visual analog scale
(VAS), 12-Item Short Form Health Survey (SF-12), and Tegner activity score
(TAS).
Results:
The mean operative time was 118 and 110 minutes in the arthroscopic and open
groups, respectively. At 2-year follow-up, scores on the AOFAS improved
significantly compared with preoperatively, from 71.3 to 96.4
(P = .006) in the arthroscopic group, and from 68.6 to
96.7 (P = .005) in the open group. The postoperative AOFAS,
VAS, KAFS, and SF-12 scores did not differ significantly between the 2
groups; however, the TAS score was significantly higher in the arthroscopic
reconstruction group compared with in the open group (7 vs 6.1,
respectively; P = .01).
Conclusion:
Arthroscopic ligament reconstruction with tendon allografting resulted in
sufficient ankle stability and no donor-site morbidity. This procedure can
yield similar functional outcomes to open reconstruction technique and may
be an option for the management of CLAI.
