**Core Concept**
Inversion injuries at the ankle can cause damage to the ligaments, bones, and other soft tissues surrounding the ankle joint. The most commonly affected structures are the lateral collateral ligaments, the anterior talofibular ligament, and the deltoid ligament on the medial side.

**Why the Correct Answer is Right**
Inversion injuries at the ankle can lead to ligament sprains, particularly of the anterior talofibular ligament (ATFL), which is the most commonly injured ligament in ankle inversion injuries. The ATFL is responsible for stabilizing the ankle joint and preventing excessive inversion. When this ligament is torn or stretched, it can cause pain, swelling, and instability in the ankle joint.

**Why Each Wrong Option is Incorrect**
**Option A:** Fracture of the medial malleolus is not a typical consequence of inversion injuries, as the force of inversion usually affects the lateral side of the ankle. However, fracture of the lateral malleolus or the fibula can occur, making this option incorrect.

**Option B:** Osteochondral fractures of the talus can occur due to the force of inversion, particularly if the talus is driven against the posterior margin of the tibia. This is a possible consequence of inversion injuries, making this option incorrect.

**Option C:** Peroneal tendon injuries can occur due to the force of inversion, particularly if the peroneal tendons are pinched or stretched as the foot inverts. This is a possible consequence of inversion injuries, making this option incorrect.

**Clinical Pearl / High-Yield Fact**
Inversion injuries at the ankle can be prevented by strengthening the peroneal muscles and improving ankle stability through exercises such as heel raises and balance training.

**Correct Answer:** A.
