Special Test

Waldron Test

Waldron Test (or as it called a unilateral squat) is used to evaluate the presence of patellofemoral syndrome or the runner’s knee.

How do you perform the Waldron Test?

  • The patient stands on the involved leg, and the clinician sits or squats next to the patient.
  • Using the entire surface of the palm, the clinician exerts slight pressure in an anteroposterior direction against the patient’s patella.
  • From this position, the patient is asked to bend the knee slowly, if possible, to about 90 degrees, while the clinician palpates for crepitus and locking of the patella and assesses the course of movement of the patella.

What does a positive Waldron Test mean?

Waldron Test is positive if pain, crepitus or locking is present, indicating the presence of patellofemoral chondropathy or patellofemoral arthrosis.

Nijs et al.1 reported unimpressive positive and negative likelihood ratios for this test.

Patellofemoral syndrome

Patellofemoral syndrome is most common in young teenage girls and young men in their 20s. It’s the most common cause of anterior knee pain.

Other differential diagnosis of anterior knee pain include:

  1. Tears of the menisci
  2. medial synovial plica syndrome.
  3. inflammatory or degenerative arthritis.
  4. tumors of the joint.
  5. ligament injuries that mimic patellar instability.
  6. Osteochondritis dissecans of the medial femoral condyle.
  7. prepatellar bursitis.
  8. patellar tendinitis.
  9. inflammation of the patellar fat pad.
  10. Sindig Larsen Johansson syndrome.
