ITBS: overuse injury from friction or pressure between ITB and lateral femoral condyle (LFC)
Occurs as response to repetitive overuse injury
Lateral synovial recess: incorrect term in some literature for space between ITB and LFC
There is no synovium in the space
"ITB recess" or "ITB space" may be better term
Iliotibial bursa: adventitious (i.e., not anatomic) bursa that may develop with ITBS
