Anterior cruciate ligament
Posterior drawer test, the posterior cruciate ligament. Apley test: patient lies prone and flexes the knee to 90 degrees. The examiner places his hand on the heel of the foot and presses firmly, opposing the tibia to the femur, then rotates internally and externally to detect any clicks, locking or pain in the knee. Internal rotation detects meniscal tear on lateral meniscus; external rotation- medial meniscus. Ballottement procedure: with patients knee extended, the examiner applies downward pressure on the suprapatellar pouch with the thumb and index finger of one hand, and then pushes the patella sharply downward against the femur with a finger of the other hand. An effusion can be detected if a tapping or clicking is sensed while the patella is pushed against the femur. Valgus stress test: bend patient knee laterally (valgus stress) while the knee joint is 30 degrees flexed. Excessive lateral movement indicates medial collateral ligament. Varus stress test: the opposite to valgus stress test, and indicated lateral collateral ligament injury. McMurray's test assesses the integrity of meniscus. This test is performed with the patient lying supine and knees fully flexed, so that the heels approach the buttocks. The examiner stabilizes the knee with thumb and index finger, and holds the heel with the other hand. The knee joint is internally rotated and extended to 90 degrees, while a medially bending (varus) stress is applied. Palpable or audible click, or limited extension of knee, will indicated a torn lateral meniscus. The same procedure can be repeated with external rotation of the knee, extend from full flexion to ninety degrees, while applying laterally bending (valgus) stress. Passive findings will indicate a damaged medial meniscus.
