Abstract: BACKGROUND: Anterolateral impingement associated with
intra-articular synovitis, scarring, and fibrosis is a less recognized feature
in patients with chronic lateral ankle instability. The aim of our study was to
ascertain the incidence of intra-articular synovitis, osteochondral lesions
(OCLs), impingement lesions (both intra- and extra-articular), and other
associated pathologies in patients undergoing modified Broström-Gould ankle
ligament reconstruction. METHODS: We performed a retrospective review of all
patients who underwent arthroscopically assisted modified Broström-Gould ankle
ligament reconstruction for symptomatic recurrent ankle instability. Patients
who had previous ankle surgery or inflammatory arthropathy were excluded. Ankle
arthroscopy was performed prior to reconstruction in all patients. Data were
obtained from clinical and radiological records including magnetic resonance
imaging scans. Arthroscopic findings were recorded in detail intraoperatively. A
total of 100 patients (53 females and 47 males) with an average age of 37 years
(range, 15-65 years) were reviewed over a 10-year period. RESULTS:
Sixty-three patients (63%) had intra-articular synovitis mostly in the anterior
and/or anterolateral compartment, which required arthroscopic debridement.
Seventeen patients (17%) were found to have OCLs, and 12 (12%) patients had
anterior bony impingement lesions. CONCLUSION: This study found a high
incidence of anterior/anterolateral synovitis in patients with chronic lateral
ankle instability. However, there was a relatively low incidence of anterior
bony impingement lesions or OCLs in our series.
LEVEL OF EVIDENCE: Level IV,
retrospective case series.
