Low Level Laser Therapy Versus Short Wave Diathermy in Patients With Anterior Cruciate Ligament Tear

This clinical research study is comparing two non-surgical treatments-Low-Level Laser Therapy (LLLT) and Short Wave Diathermy (SWD)-to see which is more effective for people with a partial tear of the anterior cruciate ligament (ACL) in the knee. The ACL is a key ligament that helps keep the knee stable during movement. When partially torn, it can cause pain, weakness, and difficulty with walking or physical activities. LLLT, also called photobiomodulation, is a painless, light-based therapy that helps reduce swelling, relieve pain, and promote healing. SWD is a type of deep heat therapy commonly used in physiotherapy to improve circulation and tissue repair. This study will include 72 patients between 20 and 40 years old who have been diagnosed with a partial ACL tear through MRI. All participants will receive standard physiotherapy exercises and SWD, while half will also receive LLLT. The study aims to find out if adding LLLT can: Reduce knee pain Improve knee muscle strength Help patients perform daily activities more easily Each participant will be monitored for 6 weeks, with check-ins at the start, the 3rd week, and the 6th week. Pain levels, muscle strength, and knee function will be measured using reliable assessment tools. The results of this study may help guide better treatment options for people with ACL injuries who want to avoid surgery.
