Hydrocolloid dressings are impermeable dressings that provide an optimal environment for wound healing. These dressings are very effective in healing chronic wounds but evidence regarding their use for the post-operative knee and hip surgery is scarce. Our experience shows that hydrocolloid dressing (Duoderm) helps in preventing not only superficial surgical site infection (SSSI) but also blister formation in patients undergoing lower limb orthopaedic surgery.
