## Core Concept
The management of intra-articular fractures involves a comprehensive approach to restore joint function, prevent post-traumatic arthritis, and minimize complications. Intra-articular fractures occur within the joint space, involving the articular cartilage and bone. The primary goals of management are to achieve anatomical reduction, stable fixation, and early mobilization.

## Why the Correct Answer is Right
The correct approach to managing intra-articular fractures includes **arthroscopic evaluation and management** (Option C), which allows for direct visualization of the joint, assessment of the fracture, and precise reduction and fixation under arthroscopic guidance. This method offers the advantage of minimally invasive surgery, potentially reducing recovery time and improving outcomes. Anatomical reduction and internal fixation (Option D) are also crucial, as they help in restoring the joint surface anatomy and providing stable fixation to allow early mobilization.

## Why Each Wrong Option is Incorrect
- **Option A:** While closed reduction and immobilization (Option A) may be suitable for some types of fractures, they are generally not adequate for intra-articular fractures, which require more precise reduction and stabilization to prevent malunion and post-traumatic arthritis.
- **Option B:** Open reduction and external fixation (Option B) might provide stability but often do not allow for the precise articular surface reconstruction needed for intra-articular fractures. External fixation is more commonly used for fractures with significant soft tissue damage or complex instability.

## Clinical Pearl / High-Yield Fact
A key point to remember is that **intra-articular fractures require surgical intervention** in most cases to achieve anatomical reduction and stable fixation, thereby reducing the risk of post-traumatic arthritis and improving functional outcomes. Early intervention and precise surgical techniques are critical.

## Correct Answer Line
**Correct Answer: C.**
