RT Journal Article SR Electronic T1 Ruptured semimembranosus bursa--an unusual complication following sports injury of the knee. JF British Journal of Sports Medicine JO Br J Sports Med FD BMJ Publishing Group Ltd and British Association of Sport and Exercise Medicine SP 23 OP 24 DO 10.1136/bjsm.20.1.23 VO 20 IS 1 A1 F Andersen-Ranberg A1 N Hejgaard YR 1986 UL http://bjsm.bmj.com/content/20/1/23.abstract AB An exceptional complication of a slight sports injury of the knee with rupture of the semimembranosus bursa in a 29-year-old male football player is reported. The diagnosis was verified by immediate arthrography, consequently the possibility of thrombophlebitis could be ruled out. Anticoagulation is dangerous and contraindicated in rupture of the semimembranosus bursa due to the risk of developing compartment syndrome. Simple bed-rest for a week gave complete relief of pain.
