Abstract: A sterile surgical sheet comprising two parallel slits and bands of adhesive bonding for prepping a patient for bilateral knee replacement surgery and providing adequate shielding from an upper thigh tourniquet. The sheet is of one-piece construction and utilizes two parallel slits for placement around a patient's legs to maintain a sterile field and seal off a tourniquet area. Outer sections of material are wrapped around and over each leg from the outside, while an inner section between the slits is folded over the patient's groin and over the outer section wrapping. Bands of adhesive bonding along the slits secure the folded assembly against the patient's legs and ensure the sheet does not come unwrapped. This provides doctors and nurses with a bounded sterile region and uninhibited access to a patient's legs. The one-piece drape provides convenience for users and reduces effort when preparing a patient prior to surgery, eliminating the use of multiple, overlapping sheets that are prone to separation.
