Inclusion Criteria

Patients with peripheral arterial disease in clinical stage 1-4 according to Rutherford-Becker classification.
Re-stenosis (=70% diameter reduction) or re-occlusion of the popliteal artery, confirmed by duplex sonography and/or angiography.
Re-stenosis or re-occlusion of the popliteal artery must not involve the superficial femoral artery and/or the anterior tibial artery and/or the tibiofibular trunk.
Have at least one open, nonstenosed (=50% diameter reduction) transtibial artery on the study leg.
Have at least one follow-up (including duplex sonography and/ or angiography), in a period of at least 12 months after re-intervention.

Exclusion Criteria

Patients with pAVK stage 0, 5, 6 according to Rutherford-Becker classification.
De novo stenosis or occlusion of the popliteal artery.
No relevant stenosis of the target lesion (<70% diameter reduction).
Ectasia or aneurysm of the popliteal artery (diameter of the target lesion >7mm)
Re-stenosis after previous surgical therapy.
Treated target lesion of popliteal artery extends to superficial femoral artery and/or anterior tibial artery and/or tibiofibular trunk.
Occlusion or relevant stenosis (>50% diameter reduction) of all arteries of the lower leg.
No follow-up examinations (including duplex sonography) of the target lesion available in a period of at least 12 months after the index procedure (lost-to-follow-up).
