- Active reduction “quad activation” of posterior tibial subluxation: This test is absolutely not as complicated as it sounds. It is pretty easy. Your doctor will simply ask you to raise your heels two to three centimeters and see how that changes the contour of your knee. If you have a posterior cruciate ligament tear, your knee will recover its normal position.
- Thessaly test: This test is designed to detect a meniscal tear, which is another common cause of chronic knee pain. Standing with both knees partially flexed, your doctor will ask you to lift one leg and stand with the other while holding their hands for support. Then you will be prompted to make rotation movements with your trunk. When this test triggers pain in the medial or lateral joint line, it suggests a meniscal tear.
- Ballottement test: This is a practical test to evaluate joint effusion. It simply consists of pushing the patella very quickly and seeing how it returns to its initial position. In case of a significant knee joint effusion, the patella will strike the trochlea and then flow back to the original position.
