Knee Examination - Orthopaedics

To clarify, from the Journal of Clinical Examination re McMurray's: To assess for a medial meniscal tear, flex the knee fully and externally rotate the foot. Apply a valgus force to the lower leg.  Now, extend the knee and note the presence of a painful click over the medial joint line as the femur passes over a tear in the meniscus. For lateral meniscal tear, flex the knee fully and internally rotate foot. Now, apply a varus force to the lower leg.  Extend the knee and note the presence of a click with pain over lateral joint line. Note, a negative McMurray’s test does not exclude a meniscal tear. The McMurray test had a sensitivity of 53 percent and a specificity of 59 percent.
