Infrapatellar neuralgia is a neurological disorder due to a lesion or dysfunction of this nerve, and is accompanied by pain and neurological deficits in region of the infrapatellar branch of the saphenal nerve.
A direct traumatic lesion of this nerve, such as dashboard trauma, knee prostheses, arthroscopy, or meniscus surgery, can cause infrapatellar neuralgia.
Signs and symptoms
Patients with infrapatellar neuralgia complain of pain, sensory loss, hyperalgesia, and allodynia of the anterior-medial side of the knee lateral to the knee tendon.
Neurological examination can show allodynia and hypoalgesia in the region of the infrapatellar nerve.
