Postoperative Orthopedic Wound Dressing Using Sterile Versus Clean Non-Sterile Technique: A Prospective Randomized Pilot Study
This prospective randomized pilot study found no difference in surgical site infection rates between sterile and clean non-sterile glove techniques for postoperative wound dressing in selected elective orthopedic procedures, suggesting that the latter is a safe and potentially cost-effective alternative.

After a surgeon closes an incision, the work is not quite finished. The wound must be cared for as it heals, a process that involves changing the bandage that covers the cut. For decades, the standard rule in hospitals has been that anyone touching that fresh wound must wear sterile gloves, the kind that are free of all germs and come in sealed packages. This rule is based on the idea that keeping the environment completely free of bacteria is the only way to prevent a surgical site infection, a complication where bacteria invade the healing tissue, causing pain, swelling, and sometimes requiring more surgery. However, in many parts of the world, sterile gloves are expensive and require significant resources to maintain. This has led medical teams to wonder if the strict requirement for sterile gloves is truly necessary for every single patient, or if a simpler approach using clean, non-sterile gloves might work just as well for certain types of low-risk surgeries.
A team of researchers at Hamad Medical Corporation set out to test this question directly. They focused on patients undergoing specific, low-risk elective orthopedic procedures, such as knee arthroscopy, reconstruction of the anterior cruciate ligament, or fixing simple fractures in the arm or ankle. These are operations where the risk of infection is already known to be very low, typically less than one percent. The researchers wanted to see if the method used to change the bandage after the surgery made a difference in whether an infection developed. They designed a study where adult patients were randomly assigned to one of two groups. In the first group, nurses changed the dressings using sterile gloves. In the second group, nurses used clean, non-sterile gloves. Both groups followed the same strict rules for cleaning their hands and preparing the skin with an antiseptic solution before touching the wound. The only difference was the type of gloves worn during the dressing change.
The study involved twenty-five patients who underwent these procedures. Thirteen patients received dressings with sterile gloves, while twelve received dressings with clean, non-sterile gloves. The nurses performed the first dressing change on the fifth day after surgery and checked the wounds again at two weeks and six weeks. The researchers looked specifically for signs of a serious infection, such as redness spreading more than one centimeter from the incision, swelling, or pus that would require antibiotics or further surgery. They also tracked whether patients had to return to the hospital, needed more operations, or had to take antibiotics after leaving the hospital.
The results were clear and straightforward. Over the six-week follow-up period, not a single patient in either group developed a clinically significant infection. The rate of infection was zero for the sterile group and zero for the clean non-sterile group. There were no differences in how long patients stayed in the hospital, and no one required readmission or additional surgery due to infection. The study also found that the process of using clean gloves was feasible and well-tolerated, with no complications arising from the technique itself.
These findings suggest that for selected, low-risk orthopedic surgeries, the use of clean, non-sterile gloves for postoperative wound care appears to be just as safe as using sterile gloves. The researchers emphasize that this does not mean sterile techniques are unimportant; rather, it suggests that once the surgery is over and the wound is closed, the extreme sterility of the gloves may not be the deciding factor in preventing infection, provided that other hygiene standards are met. The authors note that because this was a small pilot study, the results are preliminary. They call for larger, more extensive trials to confirm these findings and to fully understand the cost savings that could be achieved if hospitals could safely switch to clean gloves for these specific types of patients. Until such larger studies are completed, the current evidence offers a promising hint that the strict requirement for sterile gloves might be relaxed for certain low-risk cases without compromising patient safety.
