From 1984 to 1993, 49 cases with varioussoft tissue defects around the knee were treated with pedicled calf myocutaneous flap, lateral sural cutaneous artery island skin flap, saphenous neurovascularskin flap and fasciocutaneous flap. The postoperation results were sucessful in 47 cases, and failure 2 cases, in one case with flap infection and theother with scar formation surrounding the knee. Both the failure cases were cured with split skin graft. The patient were followed up for an average of three and a halfyears, the knee function was almost completely regained, and the blood supply of the flaps, the elasticity and colour of the flaps were similiar to that of the normal skin, without being cumbersome. The sensation of the saphenous neurovascular flaps and the lateral suralcutaneous artery island flaps was preserved, except partial numbness was presented at the distal part of the flaps. Operative indications and selection of cases were discussed.
