It necessitates an immediate operative intervention because it could potentially jeopardise the arthroplasty or even the limb. Methods Sixteen consecutive patients with a mean age of 73 8 years range 47 to76 years over a 6-year period January 2003 to December 2008 with wound dehiscence after TKA were enrolled in the present study. Unilateral or bilateral fasciocutaneous V-Y flaps that are differently oriented depending on the local conditions of the tissues were used to reconstruct the soft tissues defects. Results In 15 of the 16 cases studied the wound was successfully covered with the presented technique while in 1 patient a partial flap loss occurred which was healed after surgical debridement and the application of vacuum system. No other complications occurred. Knee prosthesis was salvaged in all the patients with a good functional and esthetical outcome. Conclusions The presented reconstructive technique is a simple quick versatile and reliable solution for the coverage of soft tissue defects following TKA more than 2 cm width and grade 1 and 2 according to Laing classification provided the V-Y flaps are applied early in the postoperative period and no complex defects are involved. Background The potentially disastrous complication of an infection after total knee arthroplasty TKA often is heralded by the delay of wound healing or soft tissue necrosis and may jeopardize the prosthesis.
