Pain over the front of the knee is common after surgery or trauma but often a definite diagnosis is difficult to make. Over the past year we have seen five cases in which the pain could be ascribed to damage to a branch of the infrapatellar branch of the saphenous nerve. Two were subsequent to trauma and three to surgical procedures. In all five cases surgical exploration gave symptomatic relief. Eight cadaveric knees were prosected to explore further the anatomy of this nerve in relation to the injuries. Injury to one of these branches should be considered in cases of persistent anterior, anteromedial or anterolateral knee pain or neurological symptoms following surgery or trauma.

“…Since IPBSN runs superficially right below the knee, there is significant chance of injury due to trauma or and iatrogenic procedure [ 7 8 9 10 ]. Clinically, patients with IPBSN lesion complain of pain and sensory disturbance such as numbness, lack of feeling, or paresthesia on the anteroinferior and medial knee.…”

“…This, in turn, effects the nature and duration of the treatment plan. Furthermore, the source of the knee pain is not always clear; knee/leg pain may be mistaken for an abnormality arising from a variety of anatomic structures, focal to the knee joint or actually emanating from another body part, such as the lumbar spine in the form of radicular symptoms or actual lumbar radiculopathy [ 10 11 ]. Therefore, IPBSN nerve conduction studies are critical and integral for the purpose of ruling in, or gruling out, a focal knee joint problem or medical issue arising from other etiology when IPBSN injury is suspected.…”

ObjectiveTo determine the optimal stimulation and recording site for infrapatellar branch of saphenous nerve (IPBSN) conduction studies by a cadaveric study, and to confirm that obtained location is practically applicable to healthy adults.MethodsTwelve lower limbs from six cadavers were studied. We defined the optimal stimulation site as the point IPBSN exits the sartorius muscle and the distance or ratio were measured on the X- and Y-axis based on the line connecting the medial and lateral poles of the patella. We defined the optimal recording site as the point where the terminal branch met the line connecting inferior pole of patella and tibial tuberosity, and measured the distance from the inferior pole. Also, nerve conduction studies were performed with obtained location in healthy adults.ResultsIn optimal stimulation site, the mean value of X-coordinate was 55.50±6.10 mm, and the ratio of the Y-coordinate to the thigh length was 25.53%±5.40%. The optimal recording site was located 15.92±1.83 mm below the inferior pole of patella. In our sensory nerve conduction studies through this location, mean peak latency was 4.11±0.30 ms and mean amplitude was 4.16±1.49 µV.ConclusionThe optimal stimulation site was located 5.0–6.0 cm medial to medial pole of the patella and 25% of thigh length proximal to the X-axis. The optimal recording site was located 1.5–2.0 cm below inferior pole of patella. We have also confirmed that this location is clinically applicable.

“…Injury of the infrapatellar nerve (IPN), a branch of the saphenous nerve (SN), is not an uncommon event. It has been reported as a complication of arthroscopic procedures, surgery, and knee trauma [1‐9]. In addition, a syndrome of IPN entrapment also has been reported [10].…”
