Purpose
The infrapatellar branch of the saphenous nerve (IPBSN) is a cutaneous nerve of the lower extremity that emerges distally to the adductor or the subsartorial canal.
Its anatomical features are well-known to be varied both between individuals,
as well as within the both limbs of the same person,
and include e.g.
emergence in respect to the sartorius muscle (SaM),
its course,
branching and morphometrics.
Iatrogenic injuries to the said nerve may occur during surgical procedures on the anteromedial side of the knee,
resulting in sensory symptoms,
neuropathic pain and uncomfortable neuromas.
One of such risky treatments involves the hamstring tendon autograft whilst reconstructing the anterior cruciate ligament,
though it is said to cause less neurological complications than the bone-patellar tendon-bone autograft.
The primary outcomes of this study involved characterisation of the IPBSN’s anatomical features.
Evaluation of iatrogenic injury risk to the nerve during the hamstring tendon grafting by the use of various incision techniques over the pes anserinus was the secondary goal of this analysis.
