This week on PA Study Sesh, we will be covering disorders of the knee and proximal tibia.
* Medial and lateral collateral ligament injuries (MCL & LCL)
* MCL=valgus stress LCL= varus stress
* MCL more common than LCL injury
* Grade I & II (sprain & incomplete tear)= conservative
* Grade III (complete) = surgical
* ACL (anterior cruciate ligament) injury
* #1 knee ligament injury
* MOI: pivoting injury, may also be hyperextension
* Females > Males
* May have associated meniscus injury
* Patient supine
* Knee flexed 20-30 degrees
* Stabilize femur and pull tibia forward
* Lack of firm endpoint is positive
* Compare both sides
* Patient needs to be fully relaxed
* Anterior Drawer
* Hip & knee bent to 90
* Stabilize foot (sit on it)
* Thumbs on joint line & pull forward
* + translates anterior without a firm endpoint
* Diagnosis MRI. May consider Xray
* PT vs Surgery (primarily surgical for younger patients)
* PCL (posterior cruciate ligament)
* Dashboard injury
* Anterior force while knees are flexed
* Typically not seen in athletes
* Posterior Drawer Test
* Posterior Sag Sign
* Elevate leg and will see the leg “sag”
* Tx: surgical
* Meniscal Tears
* Medial 3x>>> lateral (lateral is injured less)
* Less mobile & more stress is able to be applied medially
* Degenerative or traumatic (twisting or hyperflexion)
* Joint line pain
* “locking”, popping, giving way
* Difficulty with stairs (up or down) & squats
* McMurray’s Test
* Lots of ways to describe
* Grab heel with one hand and joint line with another
* Medial= externally rotate heel, flex knee, extend while providing valgus stress
* Lateral= internally rotate heel, flex knee, extend while providing varus stress
* #1 knee complaint in primary care
* Injury to patellar cartilage
* Commonly seen in runners
* Pain “under” or “behind” patella
* crepitation
* + Long car ride or theatre sign
* Difficulty with stairs
* Look for malignment and improper patellar tracking
* + patellar glide, patellar grind, patellar apprehension. Used to assess mobility and associated pain with patellar movement
