Diagnosis Path: Diagnosis typically involves a combination of clinical evaluation and imaging techniques. Healthcare professionals may perform physical examinations to assess pain points, instability, and joint function.

Treatment Protocols: Treatment approaches aim to reduce symptoms and restore knee function. Common options include:
