| Is genu valgum associated with a small or large Q-angle? | Large |
| Which direction does the patella usually dislocate? | Lateral |
| What is another name for patellofemoral syndrome and why? | Runners knee - results from excessive running, especially downhill |
| What is patellofemoral syndrome? | Pain resulting from repetitive microtrauma caused by abnormal tracking of the patella relative to the patellar surface of the femur |
| What is the most common knee injury in contact sports? | Ligament sprains, when foot is fixed in the ground |
| Which meniscus is more susceptible to tearing and why? | Medial because it is less mobile |
| Do meniscal repairs always need to be done? | No - because of the generous blood supply to this area |
| What is arthroscopy? | Endoscopic examination that allows visualization of the interior of the knee joint cavity with minimal disruption of the tissue |
| What is joint effusion? | Escape of fluid from blood or lymphatic vessels, results in increased amounts of fluid in the joint cavity |
| What three bony points are used as landmarks for needle insertion while aspirating a knee? | Gerdy's tubercle Lateral epicondyle of femur Apex of patella |
| Which bursa of the knee can be ruptured by friction between skin and patella? | Prepatellar bursa |
| Which bursa of the knee can be injured by excessive friction between the skin and tibial tuberosity? | Subcutaneous infrapatellar bursa |
| which bursa injury results in edema between the patellar ligament and the tibia, superior to the tibial tuberosity? | Deep infrapatellar bursa |
| Which bursa may be injured from abrasions or penetrating wounds? | Suprapatellar bursitis |
| What is another name for popliteal cyst? | Baker cysts |
| What are popliteal cysts? | Abnormal fluid filled sacs of synovial membrane in the region of the popliteal fossa |
| What is a popliteal cyst almost always a complication of? | Chronic knee joint effusion |
| What are shin splints? | Edema and pain the area of the distal 2/3 of the tibia |
| What do shin splints result from? | Result from repetitive microtrauma of TA which causes small tears in the periosteum covering the shaft of the tibia and/or fleshy attachments to overlying deep fascia of the leg |
| What features are unique about the human foot? | Medial migration of distal attachment of fibularis longus across sole of foot and fibularis tertius attachment to the base of the 5th MT |
| What nerve winds subcutaneously around the fibular neck? | Common fibular nerve |
| What is ski boot syndrome? | Compression of deep fibular nerve |
| What can be responsible for recurrent stretching of the superficial fibular nerve causing pain along the lateral side of the leg and dorsum of ankle and foot? | Chronic ankle sprains |
| What is the fabella and where is it located? | Sesamoid bone in the proximal portion of the lateral head of the gastroc |
| What nerve roots does the calcaneal tendon reflex test? | S1 and S2 |
| What is another name for a gastroc strain? | Tennis leg |
| What is calcaneal bursitis caused by? | Excessive friction on the bursa as the tendon continuously slides over it |
| If someone has an accessory soleus where does it appear? | As a distal belly medial to the calcaneal tendon |
| Where can the posterior tibal pulse be palpated? | Between the psoterior surface of the medial malleolus and the medial border of the calcaneal tendon |
| What position should you have the patient in to palpate the posterior tibial pulse and why? | Inversion of the foot to relax the flexor retinaculum |
| When is intermittent claudication present? | During walking, but disappears after rest |
| What is intermittent claudication characterized by? | Leg pain and cramps |
| What is is intermittent claudication caused by? | Narrowing or occlusion of leg arteries |
| Where can point tenderness be felt with plantar fasciitis? | Porximal attachment of the plantar aponeurosis to the medial tubercle of the calcaneus and on the medial surface of this bone |
| What actions cause pain with plantar fasciitis? | Passive extension of the great toe and DF of ankle and/or WB |
| What can a contusion of the extensor digitorum brevis muscle be confused with and why? | A severely sprained ankle because a contusion and tearing of these muscle fibers result in a hematoma that produces edema anteromedial to the lateral malleolus |
| What nerve roots are associated with the plantar reflex? | L4, L5, S1, S2 |
| If one has medial plantar nerve entrapment where is a good place to check this? | Medial side of the sole and in the region of the navicular tuberosity |
