Lateral ligament injuries of the
ankle are common in athletes. The majority of these patients can be treated
conservatively. However, patients with continuous pain and instability
affecting their ability to participate in sports can be treated surgically.
Chronic anterolateral ankle pain is a common complaint following ankle sprain
in athletes.
Although the exact definition of
the anterolateral aspect of the ankle is ambiguous, the area typically referred
to as anterolateral is composed of the capsule and ligament anteriorly, fibula
laterally, talus medially and inferiorly, and tibia medially and superiorly. To
date, arthroscopic examination and imaging studies have demonstrated
a variety of anterolateral ankle pathologies.
With respect to the anterolateral
region of the ankle, several pathologic conditions reportedly cause
“anterolateral ankle impingement”, including osteophytes, synovitis, thickened
scar tissue, an accessory anterior inferior tibiofibular (Bassett’s) ligament,
and loose bodies. Anterolateral impingement is defined by the presence of the
interposition of abnormal soft tissue.
