Anatomical study of the infrapatellar branch of the saphenous nerve using ultrasonography

Abstract

The infrapatellar branch of the saphenous nerve can be depicted by ultrasonography. Precise mapping of its anatomical course may have significant clinical applications.

“…As an example, the infrapatellar branch of the saphenous nerve (IPBSN) is solely a sensory nerve that innervates the anterior and inferior parts of the knee capsule as well as the skin over the antero-medial knee [52][53][54][55][56]. Several studies (including two randomized, double-blinded, placebo-controlled trials) have examined the efficacy of a selective nerve block of the IPBSN for treatment of postoperative knee pain [57][58][59][60][61].…”

“…In this study, the IPBSN was located using anatomical landmarks [54]. Subsequently, a method for locating the anterior femoral cutaneous nerve (AFCN), which innervates the anterior superior part of the knee capsule and may offer additional postoperative relief, was defined and validated in a cadaveric model [64].…”

“…Finding consistency within IPBSN branching has been the aim of many studies since. 2,9,14,16,18,34 Despite our relatively small sample size of 10 cadaveric knees, the relationship between the IPBSN and bony landmarks was no different than those reported in the large seminal study by Mochida and Kikuchi. 24 In their study of 129 knees, these authors reported an insignificant difference in the mean distance from the IPBSN to the midpatella in left (52.2 mm) and right (54.2 mm) knees.…”

“…4 Ultrasound with or without Doppler can be used to preidentify the nerve. 2,18 We personally recommend a superficial-only skin incision and the use of a blunt-tipped trocar. Additionally, structures such as the superior medial and lateral genicular arteries and the medial patellofemoral ligament occur at the region under investigation.…”

“…However, the nerve can be difficult to visualize in the medial aspect of the knee [2,3]. We currently identify and mark the maximum point of tenderness along the course of the infrapatellar nerve and scan for the nerve between the fascial planes.…”
