Most commonly injured ligaments of Ankle is
**Core Concept**
The ankle is a complex joint supported by multiple ligaments, and injuries to these ligaments are common. The most frequently injured ligaments are those on the lateral side of the ankle.
**Why the Correct Answer is Right**
The lateral ligaments, specifically the **anterior talofibular ligament (ATFL)**, **calcaneofibular ligament (CFL)**, and **posterior talofibular ligament (PTFL)**, are most prone to injury due to the mechanism of most ankle sprains, which involves inversion of the foot.
**Why Each Wrong Option is Incorrect**
**Option A:** Injuries to the medial ligaments are less common due to the stronger support provided by the **deltoid ligament**.
**Option B:** The syndesmotic ligaments can be injured, but this is less common than lateral ligament injuries.
**Option D:** Other ligaments are less frequently injured in comparison to the lateral ligaments.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that the order of injury to the lateral ligaments typically follows a sequence from anterior to posterior, starting with the **ATFL**.
**Correct Answer:** D. Anterior talofibular ligament.
