Summary

This study will observe patients with lower limb varicose veins who also have knee pain. Many patients with varicose veins experience swelling, heaviness, or aching in the legs, and some also report pain in or around the knee. Previous studies suggest that venous reflux and poor circulation may increase discomfort in the knee, especially when knee osteoarthritis is present.

The purpose of this study is to evaluate whether treatment of varicose veins with standard endovenous procedures can improve knee pain and function. Participants will undergo standard vein treatment as part of their clinical care. We will follow them for changes in knee pain, quality of life, and leg symptoms over time.

This study does not assign patients to experimental interventions. Instead, it collects information before and after treatment to better understand the relationship between varicose veins and knee pain relief. Findings from this study may help doctors identify which patients are most likely to benefit from venous treatment in terms of both leg and knee symptoms.

Conditions

  • Varicose Veins of Lower Limb
  • Chronic Venous Insufficiency, CVI
  • Knee Pain Chronic
  • Knee Osteoarthritis

Interventions

PROCEDURE

Endovenous Ablation for Varicose Veins

Participants will receive standard endovenous treatment for lower limb varicose veins as part of their routine clinical care. The procedure may include radiofrequency ablation (RFA), endovenous laser ablation (EVLA), or other accepted thermal ablation techniques, with or without adjunctive phlebectomy or foam sclerotherapy if clinically indicated. The intervention is performed under tumescent local anesthesia by vascular surgeons according to established guidelines. No experimental techniques or investigational devices are used.
