McConnell test for chondromalacia patellae
McConnell test for chondromalacia patellae(mĭk-ŏn′ĭl)
[Jenny McConnell, Australian physiotherapist]
A clinical test used to identify softening of the articular cartilage of the patella (chondromalacia patellae). With the patient seated, the femur externally rotated, and the knee flexed to 120°, the patient performs a 10-second isometric contraction. If the patient experiences pain during the contraction, the knee is passively extended and supported by the clinician, who then manually glides the patella medially. The knee is returned to the position that produced pain, and the patient again performs an isometric contraction while the medial position of the patella is maintained. If the amount of pain experienced is decreased, chondromalacia patellae is suspected. The test is then repeated at 90°, 60°, 30°, and 0° of knee flexion.
