There is no difference in recurrence between class 3 versus class 2 stocking, however compliance is higher for class 2.

There is variation in the compression afforded between different brands of class 2 and 3 stockings.

Patients with chronic venous leg ulcers and superficial venous reflux should be considered for superficial venous surgery to prevent recurrence.

Surgery does not improve ulcer healing but does significantly reduce recurrence rates at 12 months.

Healing rates are significantly increased within a specialist leg ulcer care setting (Ref 51).

Costs are lower per leg healed within a specialist

clinic compared to costs within a non-specialist clinic.

Larger case load with specialist leg ulcer clinics are recommended as the optimal service for community treatment of venous leg ulcers.
