BACKGROUND The authors report the results of preserving the infrapatellar branch of the saphenous nerve during unicompartmental knee arthroplasty to prevent lateral skin numbness. METHODS All 100 cases had medial compartmental osteoarthritis and a minimally invasive technique had been used. The mean follow-up duration was two years and eight months (range, 24 to 42 months). RESULTS The clas...

OBJECTIVE To show a rare lesion that sometimes simulates vascular disorder of the lower extremities. METHOD Three patients were operated and the follow-up period was eight months, the surgical technique was neurotomy of the infrapatellar and descendent branches. RESULTS In two cases there were almost total pain resolution, and in other case improvement only. CONCLUSION Surgical treatment ...

Knee pain is one of the most frequent complaints evaluated by orthopedic surgeons. It encompasses a broad range of pathology and can present in a variety of ways. Most of this pain can be attributed to essential structures of the knee, including the menisci, cruciate or collateral ligaments, and articular cartilage. However, there are underrecognized structures in and around the knee that can f...

BACKGROUND Standard knee arthroscopy portals are frequently used to address retropatellar chondral pathology. Alternative portals may offer a safe and simple substitute, particularly when reaching the base of deep lesions is required. PURPOSE To describe and assess the safety of accessory retropatellar portals. STUDY DESIGN Descriptive laboratory study. METHODS An anatomic study was perfo...

BACKGROUND Total knee arthroplasty (TKA) is a common procedure resulting in significant post-operative pain. Percutaneous cryoneurolysis targeting the infrapatellar branch of the saphenous nerve and anterior femoral cutaneous nerve could relieve post-operative knee pain by temporarily blocking sensory nerve conduction. METHODS A retrospective chart review of 100 patients who underwent TKA was...

Neuralgia of the saphenous nerve (SN) is a rare clinical syndrome simulating a vascular disorder of the lower extremities. In four cases, the presenting complaint was persistent pain on the medial aspect of the knee. Examination revealed tenderness over the site of exit of the SN form the femoral canal. Femoral nerve motor conduction, quadriceps H-reflex and EMG of the leg muscles were normal. ...

Background Injury to the infrapatellar branch of the saphenous nerve (IPBSN) is common after arthroscopic ACL reconstruction with hamstring tendon autograft, as reported in up to 88% of the cases. Due to close relationship between the IPBSN with pes anserine tendons insertion skin incision may sever IPBSN while harvesting gracillis and semitendinous tendons. As the IPBSN course at the anterior ...
