Understanding Knee Special Tests
What Are Knee Special Tests?
Knee special tests are structured physical examination maneuvers designed to evaluate specific structures within the knee joint, such as ligaments, menisci, tendons, and articular surfaces. They help clinicians determine the presence, extent, and nature of injuries or degenerative conditions affecting the knee.
Why Are They Important?
- Accurate Diagnosis: They assist in identifying specific injuries, such as ligament tears or meniscal damage.
- Guiding Treatment: Proper assessment informs targeted rehabilitation or surgical intervention.
- Monitoring Progress: They are useful in tracking recovery over time.
- Educational Tool: PDFs compiling these tests serve as excellent learning and reference materials.

Common Knee Special Tests: An Overview
Ligament Stability Tests
These tests evaluate the integrity of the anterior and posterior cruciate ligaments (ACL and PCL), as well as the collateral ligaments.
- Lachman Test: Assesses ACL integrity by checking anterior tibial translation relative to the femur.
- Anterior Drawer Test: Similar to Lachman but performed in a different position; assesses ACL damage.
- Posterior Drawer Test: Evaluates PCL stability through posterior tibial translation.
- Valgus Stress Test: Tests the medial collateral ligament (MCL).
- Varus Stress Test: Assesses lateral collateral ligament (LCL).
Meniscal Tests
Meniscal injuries are common in athletes and active individuals. The following tests help identify meniscal tears:
- Apley’s Test: Compression and distraction maneuvers to detect meniscal lesions.
- McMurray Test: Flexion and rotation of the knee to reproduce pain or clicking associated with meniscal tears.
- Thessaly Test: Weight-bearing rotational test performed at 5 and 20 degrees of knee flexion.
Patellar and Patellofemoral Tests
These tests evaluate patellar stability and tracking:
- Apprehension Test: Assesses patellar dislocation tendency.
- Clarke’s Sign: Checks for patellofemoral pain during quadriceps contraction.
- McConnell Test: Evaluates patellar tracking with specific positioning.
Other Important Tests
Additional assessments include:
- Ely’s Test: Checks for rectus femoris tightness.
- Thessaly Test: For meniscal pathology.
- Bounce Home Test: Detects meniscal or cartilage lesions.
