Localized Pigmented Villonodular Synovitis of the Posterior Knee Compartment with Popliteal Vessel Compression: A Case Report of Arthroscopic Resection Using Only Anterior Knee Portals

<div>(a) Lateral-view T2 sequence MRI of the left knee 6-month post arthroscopic resection of posterior-compartment PVNS, showing no more compressive effect on both the cruciate ligaments and the popliteal vessels. (b) There is a significant decrease in the soft tissue enhancement suggestive of decreased inflammation in the region of the resected lesion. There is no evidence of interval appearance of new susceptibility artifacts or blooming effect suggesting recurrence.</div>
