If the tibia pulls forward or backward more than normal, the test is considered positive. Excessive displacement of the tibia anteriorly suggests that the anterior cruciate ligament is injured, whereas excessive posterior displacement of the tibia may indicate injury of the posterior cruciate ligament.

The drawer sign: The examiner stands behind the dog and places a thumb on the caudal aspect of the femoral condylar region with the index finger on the patella. The other thumb is placed on the head of the fibula with the index finger on the tibial crest. The ability to move the tibia forward (cranially) with respect to a fixed femur is a ...
An additional test of posterior cruciate ligament injury is the posterior sag test, where, in contrast to the drawer test, no active force is applied. Rather, the person lies supine with the leg held by another person so that the hip is flexed to 90 degrees and the knee 90 degrees. [ 3 ]
Posterior drawer test and tibial sag tests can determine the integrity of the posterior cruciate ligament. Similar to anterior drawer test, the knee should be flexed 90 degrees and the tibia is pushed backwards. If the tibia can be pushed posteriorly, then the posterior drawer test is positive.
Anterior cruciate ligament surgery is a complex operation that requires expertise in the field of orthopedic and sports medicine. Many factors should be considered when discussing surgery, including the athlete's level of competition, age, previous knee injury, other injuries sustained, leg alignment, and graft choice.
Lachman & Posterior drawer tests - Increased anterior translation on the Lachman test is found when the patient has had a combined ACL and PLC injury. Increased posterior translation on the posterior drawer test indicates a combined posterior cruciate ligament tear with the PCL injury.
Some retailers are using President-elect Donald Trump's proposed tariffs to urge consumers to shop now, suggesting if the import duties go into effect next year, a range of goods could cost ...
The posterior cruciate ligament (PCL) is a ligament in each knee of humans and various other animals. It works as a counterpart to the anterior cruciate ligament (ACL). It connects the posterior intercondylar area of the tibia to the medial condyle of the femur. This configuration allows the PCL to resist forces pushing the tibia posteriorly ...
