Suprapatellar Fat Pad Impingement due to Vascular Lesion: A Case Report

Area of Science:

• Orthopedic surgery
• Vascular lesions
• Pediatric orthopedics

Background:

• Suprapatellar fat pad impingement is a potential cause of anterior knee pain.
• Vascular lesions are an uncommon etiology of suprapatellar fat pad issues.
• Diagnosis often involves imaging and clinical evaluation.

Observation:

• A 15-year-old male presented with anterior knee pain and swelling.
• Tenderness and pain were noted in the suprapatellar region, especially with terminal extension.
• Imaging suggested a vascular lesion within the suprapatellar fat pad.

Findings:

• The patient underwent arthroscopic debridement of the suprapatellar lesion.
• Post-operatively, the patient regained full terminal knee extension.
• Histopathological examination of excised tissue is crucial for definitive diagnosis.

Implications:

• Arthroscopic debridement is an effective treatment for vascular lesions of the suprapatellar fat pad.
• Surgical intervention can successfully alleviate pain and restore function in refractory cases.
• This case highlights the importance of considering vascular lesions in the differential diagnosis of suprapatellar pain.
