Background to Appley's
[edit | edit source]
The Appley's grind test is used to evaluate individuals for problems of the meniscus in the knee. This test is named after Alan Graham Appley (1914 - 1996), a British orthapedic surgeon, who discovered this assessment technique[1].Diagnosis of meniscal injuries can be difficult as the menisci are avascular and have no nerve supply on their inner two thirds, resulting in very little pain or swelling when an injury occurs[2]
Test Description
[edit | edit source]
Appley's grinding test involves placing the patient in the prone position with the knee flexed to 90 degrees[3]. The patient's thigh is then rooted to the examining table with the examiner's knee. The examiner laterally and medially rotates the tibia, combined first with distraction, while noting any excessive movement, restriction or discomfort. The process is then repeated using compression instead of distraction[2]. If rotation plus distraction is more painful or shows increased rotation relative to the normal side, the lesion is most likely to be ligamentous[2]. If the rotation plus compression is more painful or shows decreased rotation relative to the normal side, the lesion is most likely to be a meniscus injury[2].
Reliability of The Test[edit | edit source]
Many studies have attempted to quantitate the reliability of various physical examination findings. In a prospective study comparing preoperative joint line tenderness to arthroscopic findings of meniscal tears, the sensitivity of joint line tenderness was found to be 86% and 92% with an overall accuracy rate of 74% and 96% for the medial and lateral meniscus, respectively, another study found similar results, with joint line tenderness having a sensitivity of 74%. The only significant McMurray sign to correlate with a meniscal injury was a “thud” elicited on the medial joint line with a medial meniscal tear. However, the McMurray and Apley tests were found by others to have less than 75% sensitivity for diagnosing meniscal tears.5
Sensitivity of the Test
[edit | edit source]
Diagnostic accuracy studies of meniscal tests are described to have poor methodologic quality with highly heterogeneous results, therefore poor value for clinical practice.6 A recent meta-analysis reports sensitivity and specificity to be 60% and 70% respectively.7
