The Impact of Photobiomodulation Therapy on Swelling Reduction and Recovery Enhancement in Total Knee Arthroplasty: A Randomized Clinical Trial.

Total knee arthroplasty (TKA) is commonly performed for severe osteoarthritis but often results in significant postoperative swelling and discomfort, impacting early rehabilitation. Photobiomodulation therapy (PBMT), utilizing low-level laser therapy (LLLT), has emerged as a potential adjunctive treatment to alleviate these symptoms. In this single-center, nonblinded prospective randomized clinical trial, conducted from May to July 2024, 30 patients undergoing primary TKA were enrolled and divided into two groups.
