Clinical Study Demonstrates Benefits of Photobiomodulation Therapy After Total Knee Replacement

  • Reading time:3 mins read

We’re pleased to announce that our medical device was used in a recent clinical study evaluating the effects of photobiomodulation therapy (PBMT) following total knee arthroplasty (TKA). The study, now published on PubMed, offers new evidence supporting the role of PBMT in reducing postoperative swelling and improving early mobility outcomes.

Study Overview

Objective:
To assess whether PBMT, when used alongside standard postoperative care, can reduce swelling and enhance functional recovery after knee replacement surgery.

Design:

  • Single-center, nonblinded randomized clinical trial
  • 30 patients undergoing primary TKA
  • Control group (n=15): Standard postoperative care
  • PBMT group (n=15): Standard care + PBMT from postoperative day 1 to 5
  • Outcomes measured:
    • Swelling (via bioimpedance analysis)
    • 2-minute walk test (2MWT)
    • Active range of motion (aROM)
    • Visual Analogue Scale (VAS) pain score

Key Findings:

  • PBMT group showed significantly reduced swelling by postoperative day 6.
  • Improved early mobility: PBMT group walked 27 m in 2MWT vs. 16 m in control group.
  • No significant difference in aROM or pain scores.
