Wound closure after total knee replacement: Comparison between staples and sutures
Background and Objective: Total Knee Arthroplasty is a commonly performed procedure for arthritic knees. Preventing complications is of utmost importance for good functional outcomes and preventing morbidity. Wound closure after the procedure is as important as the replacement aspect of surgery.The objective of this study was to provide subjective and objective evidence of better closure technique and material; we conducted the study so that the outcome of TKA can be further improved.
Methods: We conducted a randomized trial at The Indus Hospital, Karachi, from December 2018 to June 2020. All patients from age 40 to 70 years who underwent total knee arthroplasty were included in the study. The wound of one knee was closed with Polypropylene (Prolene) sutures, and the other with staples. The wound was assessed independently by two assessors using Hollander’s score; lower score means a worse outcome. All data was entered and analyzed using STATA version 16.
Results: Thirty patients who underwent bilateral total knee replacement were included in the analysis, among which 71.8% were female. The average age of participants was 57.3 (± 7.5) years. The mean incision length on the right knee was 17.6 ± 1.1 cm, while on the left the incision length was 18.3 ± 1.2 cm. Overall, the mean Hollander score was significantly different among participants in the sutures and staples group in both the right (p-value=0.001) and left knees (p-value=0.001). The score was significantly higher in knees closed with sutures as compared to staples. Also, the mean Hollander score is significantly higher in females than males in both the right knee (B=0.56, p-value=0.049) and the left knee (B=0.38, p-value=0.044).
Conclusion: The study has shown that Hollander’s score was significantly higher in knees closed with sutures as compared to the patients in whom staples were used for wound closure.
