Bilateral nerve entrapment in the popliteal space

Area of Science:

• Orthopedic Surgery
• Neurology
• Musculoskeletal Disorders

Background:

• Nerve entrapment in the popliteal space is a rare cause of knee pain.
• Idiopathic cases present diagnostic challenges, particularly with posterior knee pain.
• Activity-related pain and localized tenderness are key indicators.

Observation:

• A rare case of bilateral idiopathic nerve entrapment was identified.
• The condition affected the popliteal space, leading to significant knee pain.
• Physical examination revealed localized tenderness over the affected area.

Findings:

• Surgical decompression of the entrapped nerves provided complete symptom relief.
• The patient experienced sustained relief, remaining symptom-free five years post-surgery.
• This case highlights the importance of considering nerve entrapment in differential diagnoses.

Implications:

• Highlights nerve entrapment as a crucial differential diagnosis for posterior knee pain.
• Emphasizes the effectiveness of surgical decompression for idiopathic popliteal nerve entrapment.
• Suggests that prompt diagnosis and surgical intervention can lead to long-term pain relief and improved function.
