When examining a knee for a meniscal injury the commonly described tests are the McMurray Test and Apley Test.  However, these tests have sensitivities of 48-68% and 41% respectfully, and specificities of 86-94% and 86-93% respectfully.  Depending on whether you are looking at the medial or lateral meniscus.
当检查膝关节半月板损伤时，最常用的是McMurra试验和Apley试验。但是，这两个试验敏感性分别为48%-68%和41%，特异性为86%-94%和86%-93%。取决于你是要检查内侧或外侧半月板。
The Tessaly Test that was first described in 2005 can be performed with knee in either 5 or 20 degrees of flexion and has a senstivity of 89-92% and specificity of 96-97% when performed in 20 degrees flexion.  The test also tends to be easier to perform.
在2005年首次报道的Tessaly试验要使膝关节弯曲5°或20°，当在膝关节弯曲20°检查时，敏感性为89-92%，特异性为96-97%，这个试验也更容易操作。
To perform the test:
如何操作：

•Stand on affected leg only with the other leg held up in the air.  The examiner holds hands for balance.
• 用要检查的腿站立，将另一条腿抬高凌空。检查者扶住患者的双手，保持平衡。
•Flex knee to be test to 20 degrees
•将膝关节弯曲20° 。
•Internally and Externally Rotate Knee
•向内和向外旋转膝关节。
•Positive test is pain at medial or lateral joint line with possible locking/catching sensation
•阳性试验为内侧或外侧关节线上出现疼痛，可能伴有关节“锁定”或“阻滞”感。
Essentially you and your patient will look like you are doing the twist as they rotate their knee with you holding their hands.
你和你的病人看起来好像再做扭转动作， 因为在他们旋转他们的膝关节时，你在扶住他们的双手。
