Clark's Test for Cartilage Damage

Aug 23, 2025

Overview

Clark's test is a clinical procedure used to assess for damage to the retropatellar cartilage by evaluating pain response during quadriceps contraction.

Clark's Test Procedure

  • The examiner applies gentle distal pressure on the patella, guiding it into the trochlear groove.
  • The patient is instructed to contract the quadriceps muscle while the examiner prevents the patella from moving proximally.

Interpretation of Results

  • Pain elicited during quadriceps contraction suggests possible damage to the retropatellar (articular) cartilage.
