2. Knee Tests & Disorders Flashcards
Medial mensiscus palpation
Palpable in IR; Pain with ER if injured
Lateral Collateral Ligament Palpation
Palpable in Tailor’s position
(Common) Peroneal/Fibular Nerve
Behind fibular head; posterior & lateral branches
Valgus Stress Test of Knee
Tests for instability of MCL; tests for sprain of MCL. Apply Valgus pressure (try to force leg into knock-kneed position)
Varus Stress Test of Knee
Tests for instability of LCL. Apply Varus pressure (try to force leg into bow-legged position)
Anterior Drawer Test
Tests ACL instability by pulling tibia anteriorly; if tibia can be pulled forward, ACL is not intact
Posterior Drawer Test
Tests PCL instability by pushing tibia posteriorly; if tibia can be pushed back, PCL is not intact
Lachman Test
Tests ACL instability by pulling tibia anteriorly; if tibia can be pulled forward, ACL is not intact
Modifid Lachman Test
Hang lower leg off table; Use table to stabilize upper leg. Tests ACL instability by pulling tibia anteriorly; if tibia can be pulled forward, ACL is not intact
Pivot Shift Test
Tests ACL instability; Valgus stress with IR; Perform in ext and at 30; Difficult test used by orthopaedists
Apply’s Compression (Grind test)
Tests meniscal tears; Place downward pressure on the ankle and IR/ER; Pain w/ IR = Lat mensiscus tear; Pain w/ ER = Med meniscus tear; Also painful with injured capsule & ligaments
Apply’s Distraction
Tests capsule and ligament sprains; Pull ankle upward and IR/ER; Pressure taken off meniscus; Pain w/ IR = lat side; pain w/ ER = med side
McMurray’s Test
PRIMARY MENISCUS TEST!!! Passively flex hip & knee and ER, then passively extend hip and knee in IR & pull knee lat; CLICKING & PAIN INDICATIVE OF MENISCUS TEAR
Patella Crunch Test (Clarke’s)
Tests for Patellofemoral Syndrome; 1) Patient contracts quad; 2) Patient contracts quad while provider applies slight pressure; 3) Patient contracts quad while provider applies more distal pressure
Apprehension Test of Knee
Attempt to displace patella laterally; Positive = pain & fear of dislocation
Knee Effusion Test
Milk edema to one side and release
Ballotable Test
Push down on patella and watch it float up; incative of edema
Bounce Home Test
AWEFUL TEST!!! DON’T EVER DO THIS!!! Place patient leg into 30 flex; as s/he relaxes, drop leg into extension and watch for it to bounce back
Quadricep Muscle Contusion - Mechanism
Mechanism = Direct blows
Quadricep Muscle Contusion - S/Sx
S/Sx = pain, edema, ecchymosis, decreased knee ext
Quadricep Muscle Contusion - Complication
Complication = Myositis Ossificans
Myositis Ossificans
Development of bone in muscle due to calcification during inflam. process; Develops from blood pooling close to bone; Start massaging quickly to push blood away from area of injury
Quadricep Muscle Strain - Mechanism
Mechanism = Forceful overstretch or contraction
Quadricep Muscle Strain - S/Sx
S/Sx = point tender; edema; spasm; pain on extreme flex & resistive ext
