Dermal hypoesthesia is a well-recognized sequelae of total knee arthroplasty (TKA). However, it is poorly documented. Thirty-five knees were evaluated for hypoesthesia among 26 patients after TKA to determine the incidence, area affected, and change over time in situ. All knees sustained an area of hypoesthesia, showing diminution over time. All were affected lateral to the medial parapatellar incision. A 71% decline of the area affected was seen over the first 2 years after surgery. All patients had some residual hypoesthesia with a mean of 33 cm2 at 2 years.
皮肤感觉减退是全膝关节置换术（TKA）公认的后遗症。然而，相关记录较少。对26例患者行TKA术后的35个膝关节进行感觉减退评估，以确定发病率、受影响区域及随时间的原位变化。所有膝关节均有感觉减退区域，且随时间逐渐减小。所有病例均在髌旁内侧切口外侧出现感觉减退。术后前2年，受影响区域面积下降了71%。所有患者均有一定程度的残余感觉减退，2年时平均面积为33平方厘米。
