ABSTRACT

BACKGROUND:

The midline incision during total knee arthroplasty (TKA) is known to damage the infrapatellar branch of the saphenous nerve (IPBSN), leading to lateral flap numbness. The aim was to evaluate the rate of persistent skin numbness (RSN) and area of skin numbness (AON) after a lateral-based skin incision compared with the standard midline incision in bilateral TKA patients.

METHODS:

Thirty-six patients undergoing bilateral TKA were included and randomly assigned to receive the lateral skin incision (lateral side of the tibial tubercle) on one knee and the standard midline incision on the contralateral. All other surgical steps were identical. Primary outcomes were the RSN at 1 year and the AON at 6 weeks, 3, 6, and 12 months postoperatively. Kneeling ability test (KAT), operative time, and length of incision were also recorded.

RESULTS:

The lateral incision had half the RSN at 12 months compared to the midline incision (25% vs 53%; p = 0.01). The median AON at 1-year after surgery was 0 [0-0.5] cm2 in lateral incision vs 4 [0-7.5] cm2 in midline group (p < 0.001). KAT was minimally better in the lateral group at 110° of kneeling between 6-month to 1-year. Operative time and length of incision were similar between both groups.

CONCLUSION:

The lateral skin incision reduced RSN by approximately 50% compared with the midline incision. The AON in lateral incision was 4 cm2 smaller than midline at 1-year after surgery. Moving a skin incision more lateral may be considered to minimize the numbness after TKA.
