Treatment of chronic recurrent synovial fistulae with myofascial flaps

Chronic recurrent synovial fistulae of the knee are uncommon. They can occur as a surgical complication or as a consequence of traumatic injuries. Conservative treatment is usually adequate for initial management, but no consensus exists about the treatment for chronic or recurrent cases and the literature on the subject is scarce. Two cases are presented in which initial conservative and subsequent conventional surgical management failed and reconstruction with regional myofascial flaps was required.
