Accuracy of the posterior drawer test

The posterior drawer test is not a very accurate assessment, and it is better to augment the examination with stress X-rays.

• Quote from peer-reviewed paper:

  "....While patients with [posterior tibial translation (PTT)] values ≥ 10 mm should undergo surgery, those with PTT values  < 10 mm may be treated conservatively...."

• Quote from peer-reviewed paper:

  "....Stress radiography was more sensitive for detecting posterior tibial translation than KT-1000 and KT-2000....posterior stress radiography with TELOS and kneeling stress radiography are the most reliable methods to evaluate posterior cruciate ligament laxity."
