Wound Closure Techniques for Total Knee Arthroplasty: An Evidence-Based Review of the Literature

Ultimately, no optimal closure technique has been developed, and current studies do not provide a clear evidence-based answer. This field needs much more evidence-based studies before one can draw conclusions. Even though some of these studies are prospective and randomized, they may not be generalizable. Also, many of the studies have small numbers and are subject to type II errors and fragility. Certainly, more studies are needed to truly understand the advantages and disadvantages of these new methods. Nevertheless, this review allows orthopedists to evaluate the differences between closure methods.
