We report a case of leakage of irrigation fluid into the extraarticula
r soft tissue, due to rupture of a Baker's cyst during arthroscopy of
the knee joint. A four - quadrant fasciotomy of the calf musculature w
as performed to prevent the devasting ischemic complications of an imm
inent compartment syndrome. A survey of the literature reveals no cons
ensus regarding the treatment of such complications. On the contrary,
some authors recommend avoiding fasciotomy and waiting for spontaneous
reabsorption of the irrigation fluid.
