what force causes LCL sprains? | Varus force. |
what is the cause of ACL sprains? | non contact rotational or hyperextention |
what is the cause of PCL sprains? | hyperflexion or hyperextention while the knee is distracted. |

Special test to determine posterolateral rotary instability | dial test, external rotation recuvatum test, posterolateral drawer test, reverse pivot shift, and dynamic posterior shift test. |
what force causes meniscal tears? | rotation and flexion |
Which meniscus (medial or lateral) is involved in tears more often? | Lateral |
SIgns and symptoms of torn meniscus? | Locking and clicking |
Special Tests for meniscal tear | McMurray's, Apley's, and Thessaly test |

Signs and Symptoms of IT band friction synodrome | pt describes "burning" over the lateral femoral condyle that may radiate distallly. Pint tenderness where IT band passes over epicondyle. pain during MMTof hamstringsor quad but no pain in AROM/PROM |
Special Test for IT band friction syndrome | Noble compression test |
Special Test for IT band tightness | Ober's test. |
what force causes tibiofemoral joint dislocations? | knee hyperevtension combined with tibial rotation; postior displacement of the tibia with the knee flexed. Or an extreme force across the joint line can result in dislocation. |
Partial tibiofemoral dislocation (frank dislocation) should be suspected if... | If there is distal neurovascular symptoms and 3/4 of the knee ligaments are torn. |
