Abstract:
Objective:To investigate the clinical effect of saphenous artery perforating branch flap in repairing anterior knee soft tissue defects with patella exposure.Methods:From July 2010 to September 2017, 12 patients whose patella exposed due to anterior soft tissue defects of knee were treated. The 12 cases included 8 males and 4 females, aged from 24 to 60 years (42.6 years on average). The causes of injury included car accident in 5 cases, rolling injury in 3 cases, burn and scald in 2 cases, and postoperative patella fracture in 2 cases. The areas of the wounds ranged from 6 cm × 5 cm to 8 cm × 7 cm. The wounds were repaired by saphenous artery perforating flaps with the area ranged from 7 cm × 6 cm to 9 cm × 8 cm, and the donor sites were repaired with free skin grafting.Results:All the 12 cases ended up with the wounds healed primarily and no postoperative complications. The 12 cases were followed up for 6 months to 24 months, with an average of 12 months. The color, texture and appearance of the flaps were good, the thickness of the flap were moderate, and the function of knee joint was recovered well. Skin flap sensation was graded according to the criteria of the British Medical Research Society: 2 cases for Grade S 3+, 6 cases for Grade S 3 and 4 cases for Grade S 2. Conclusions:Saphenous artery perforating flap is an effective method to repair anterior knee soft tissue defect and patella exposure.
