Knee (Outline) Flashcards
what is ________ which is caused by posterior germination of the synovial membrane through the joint capsule into the popliteal fossa. Sweliing appears below joint line and may extend as dar as the mid calf. Large swelling may interfere w/ knee movements but otherwise asymptomatic.
baker’s cyst
what is ______ which is caused from inflammation of the bursa surrounding the knee because of repeated frictional forces. In chronic inflammation, bursar become distended and filled w/ fluid.
bursitis
prepatellar bursitis is also known as?
housemaid’s knee
infrapatellar bursitis is also known as?
clergyman’s knee
what is located between femur and quadriceps tendon?
suprapatellar
what is located between lateral tibial condyle and popliteus tendon?
popliteus
