Objective:
This study aimed to compare two methods of wound skin closure-staples versus vertical mattress nylon sutures-in patients undergoing primary total hip (THR) and total knee replacements (TKR). The comparison was for wound complications as a primary outcome, and satisfaction of patient and nurse as secondary outcomes.
Method:
A prospective cohort study was conducted at an academic teaching hospital. All the patients who were admitted for either primary THR or TKR from September 2018 to September 2019 were included. Revision surgeries, patients >85 years of age, and those who were on steroid therapy were excluded. Patients were divided into two groups (staples and sutures) to compare the two methods of wound closure. Patients in each group were assessed for characteristics such as age, sex, weight, height, comorbidities, smoking status, postoperative wound complications, reoperation and patient/nurse satisfaction.
Results:
A total of 100 patients met the inclusion criteria. In the staples group (n=50), 26 patients underwent THR while 24 patients underwent TKR. In the sutures group (n=50), 23 patients underwent THR and 27 patients underwent TKR. Overall, there was no significant difference between the two groups (staples versus sutures) in terms of wound complications (p=0.401), patient satisfaction (p=0.357) and nurse satisfaction (p=0.513). Further analysis compared THR and TKR subgroups (THR staples versus THR sutures and TKR staples versus TKR sutures). The results showed no significant difference between the staples and sutures subgroups of THR and TKR in terms of wound complications, patient satisfaction and nurse satisfaction.
Conclusion:
In THR and TKR, there was no significant difference between either vertical mattress nylon sutures or staples primary skin closure in terms of wound complications and patient satisfaction in this study. The decision on wound closure method should be based on the availability of resources in the institution/country.
