You are evaluating the normal patellar positioning during the motion of knee extension to knee flexion in a patient that complains of knee pain. Under normal conditions you will expect:

A snowmobile driver left the trail and struck a tree. The driver’s left knee was flexed at approximately 90 degrees and the tibia was impacted anteriorly creating a vector force in a posterior direction (from anterior to posterior). What would this mechanism of injury MOST result in?

The deep segmental muscles that collaborate with the lumbar intra-abdominal pressure and resultant stability of the lumbar spine are:
From flexion to extension the patella glides superiorly, whi…
From flexion to extension the patella glides superiorly, which muscle helps to stabilize the patella the most during the end range of extension?

The effects of rotation of the knee on the menisci are dissimilar, thus their injury rate is different because:
The talocrural joint has an oblique axis which during non-we…
The talocrural joint has an oblique axis which during non-weight bearing dorsiflexion, in the transverse plane around a vertical axis facilitates the combined motion of:
