A Clinical Trial to Evaluate the Safety and Effectiveness of OLIZ, a Photobiomodulation Medical Device for Surgical Site Pain Relief in Patients After Total Knee Arthroplasty

OLIZ device utilizes dual-wavelength technology combining specific red (660nm) and near-infrared (850nm) light parameters optimized for post-surgical tissue healing. The device features controlled power density, precise treatment duration protocols, and targeted application to knee arthroplasty surgical sites. Treatment parameters include specific irradiance levels, treatment session duration of 15 minutes, and 3 times of daily application frequency designed.
