Prolene is a brand of synthetic polypropylene used in monofilament nonabsorbable sutures and meshes. The suture is indicated for skin closure and general soft tissue approximation and ligation. Its advantages include minimal tissue reactivity and durability. Disadvantages include fragility, high plasticity, high expense, and difficulty of use compared to standard nylon sutures.
