• General knee-specific outcome measure for patients with ligament or meniscal injuries.
• Evaluating symptoms, function, and sports activity across a variety of knee conditions (ACL/PCL, Meniscus, Patellofemoral).
• Pre- and post-operative monitoring of surgical interventions.

• Symptoms: 7 items (Pain, Stiffness, Swelling, Locking, Giving way).
• Sports Activity: 2 items (Highest level of activity without symptoms).
• Function: 2 items (Current vs. Pre-injury function).

Scores range from 0 to 100. Higher scores represent better function and fewer symptoms.

The IKDC is generally considered more responsive to change across a broader spectrum of knee pathologies than the Lysholm score, which is more focused on instability (ACL/meniscus).

• An IKDC score of 100 indicates perfect function in both ADLs and high-demand sports.
• Minimal Clinically Important Difference (MCID): A change of ~11.5 points for ligament/meniscus injuries.
• Serial IKDC tracking is highly correlated with long-term patient satisfaction after ACL reconstruction.

• Score Improvement: Demonstrates effectiveness of current rehab/surgical strategy.
• Plateauing Scores: May indicate a need for more intensive strengthening or a change in surgical approach (e.g., cartilage restoration).
• Low Activity Scores: Focus on "Sport-Specific Drills" if the "Activity" domain is the primary driver of the low score.
