Objective: To evaluate surgical outcomes using sets of techniques to achieve single dry dressing for two weeks post total knee replacement (TKR) at Dr. Sulaiman Al-Habib Hospital, Riyadh, Saudi Arabia.
Material and methods: A prospective study comprised of 110 consecutive unilateral total knee replacements was conducted at the orthopedic department of Dr. Sulaiman Al-Habib Hospital, Suwaidi, Riyadh, KSA. Patients of both genders underwent knee replacement surgery due to primary knee osteoarthritis, Kellgren-Lawrence grades 3 and 4. Routine investigations and fitness evaluations of patients were carried out preoperatively. Preoperative minimal use of a tourniquet and release prior to arthrotomy closure; intravenous tranexamic acid, no drains; capsule infiltration with local anesthetics without adrenaline; tight closure with barbed sutures up to the skin in three layers; skin glue; Aquacel dressing; adductor canal block; and continuation of oral anticoagulant for four weeks.
Results: A total of 110 cases were included, of which 81 (73.6%) were females and 29 (26.4%) were males. The mean age of the study population was 60.5+10.3 years (48 to 88 years). The mean BMI in our patients was 30.57+10.5 kg/m2. Most patients were morbidly obese 13 (30.95%). The mean preoperative Hb% was 13.07+1.6 g/dl, while the mean postoperative Hb% was 12.58+1.9 mg/dl with a p-value of 0.28, which was non-significant statistically. Only two patients needed a change of Aquacel wound dressing for ooze. None of our patients developed deep venous thrombosis (DVT) or an infection.
Conclusion: A sequential use of sets of techniques is observed to be associated with improved outcomes in terms of blood loss, wound infection, mobility, and patient satisfaction, leading to the ultimate end point of dry Aquacel wound dressing.
