Soft tissue reconstruction around joints such as the knee requires a few additional considerations compared with other regions. The overlying skin must be pliable, with adequate distensibility to maintain the range of motion as a hinge joint, and ideally be replaced with "like-for-like" tissue to restore its delicate contour. The advent of perforator flaps has provided reconstructive surgeons with thin, pliable flaps conferring superior aesthetic results, good preservation of joint range of motion, and less donor site morbidity. Utilizing locoregional options also allows replacement with "like-for-like." We retrospectively reviewed lower medial thigh perforator flaps performed for traumatic and debrided infected knee wounds, using a free-style approach to flap harvest. The described technique was found to be reliable, with consistent anatomy. All flaps survived and successfully covered small- to medium-sized critical defects in healthy individuals and those with multiple comorbidities.
与其他部位相比,膝关节等关节周围的软组织重建需要一些额外的考虑因素。覆盖其上的皮肤必须柔韧,具有足够的伸展性,以维持作为铰链关节的活动范围,理想情况下要用“同类”组织进行替代,以恢复其精致的外形。穿支皮瓣的出现为重建外科医生提供了薄而柔韧的皮瓣,能带来更好的美学效果,更好地保留关节活动范围,且供区并发症更少。利用局部区域的选择还能实现“同类”替代。我们回顾性分析了采用自由式皮瓣切取方法,为创伤性和清创后感染的膝关节伤口进行的大腿内侧下穿支皮瓣手术。结果发现,所描述的技术可靠,解剖结构一致。所有皮瓣均存活,并成功覆盖了健康个体以及患有多种合并症个体的中小面积关键缺损。
