Clinical Trial Summary

The aim of this study is to evaluate the effects of high intensity laser therapy (HILT) on range of motion, pain, quality of life, muscle strength and femoral cartilage thickness in patients with knee osteoarthritis.

Description:

Patients who are admitted and diagnosed with knee osteoarthritis based on anamnesis, physical examination and imaging methods are included in the study.

Intervention

Other:
• high-intensity laser therapy
A total of 15 sessions of hotpack, TENS and exercise program will be applied to the patients for three weeks, 5 days a week, 1 session a day. The patients in the HILT group will be treated with a BTL 6000 brand device (Figure 5) for 3 sessions of high-intensity laser with a power of 10.0 w in the first week, energy density of 12 j/cm², every 25 cm² for 2 minutes in analgesic mode, and 5 sessions in the following 2 weeks. While 6 sessions of .0 w power, energy density of 120 j/cm², each 25 cm² for 10 minutes, will be applied in biostimulant mode for 6 sessions for three weeks, is applied in analgesic mode for 3 sessions every other day in the first week, and 6 sessions every other day in the biostimulant mode for the next two weeks, for a total of 9 sessions for three weeks.
• sham high-intensity laser therapy
Hotpack, TENS and exercise program applications will be applied to the patients in the same way as in the HILT group, 5 days a week, 1 session a day, a total of 15 sessions for three weeks. HILT is administered as a placebo for three weeks, 3 sessions a week, every other day, for a total of 9 sessions.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Visual Analog Scale (VAS) Change from baseline in pain on the VAS at month 3	Visual Analog Scale (VAS) is used to measure and monitor the intensity of pain. This is a 10 cm ruler that describes painlessness at one end and the most severe pain at the other. A patient scores his/her pain from 0 to 10.	Baseline and month 3
Secondary	Knee joint range of motion Change from baseline in knee joint on the measuring the range of motion at knee joint at month 3	The range of motion of the patients, consisting of knee flexion and extension, is actively evaluated with a goniometer. In the measurement of the flexion angle, the patient is lying in the prone position and the extension angle is measured as the limitation of extension when the knee joint is at 0 degrees	Baseline and month 3
Secondary	Femoral cartilage thickness Change from baseline in knee joint on the measuring the femoral cartilage thickness at month 3	Femoral cartilage thickness is measured by the same physician by placing the probe axially in the suprapatellar region by ultrasonography while the patient is lying on his back and the knees are in maximum flexion. The distance between the thin hyperechoic line at the synovial cartilage interface and the sharp hyperechoic line at the cartilage-bone interface is defined as cartilage thickness	Baseline and month 3
Secondary	SF-36 quality of life scale Change from baseline in physical and mental functions on SF-36 quality of life scale at month 3	The SF-36 scale measures 8 dimensions of health and consists of 36 items; physical function (10 items), social function (2 items), role related to physical functions limitations (4 items), role limitations due to emotional problems (3 items), mental health (5 items), energy/fatigue (4 items), pain (2 items), and general perception of health (5 items). It is evaluated between 0 and 100 points; 0 represents poor health, 100 represents good health. There are two summary components, the physical component and the mental component	Baseline and month 3
Secondary	Western OntarioMacMaster (WOMAC) Change from baseline in pain and physical functions on Western OntarioMacMaster scale at month 3	It is widely used in studies with knee OA patients. The scale, each question of which is evaluated with a 5-point Likert scale, consists of 24 questions. It is filled by patients. There are pain, physical function and stiffness subscales. Pain subscale is evaluated with five items and is scored between 0-20. The hardness subscale has two items and is scored between 0-8. Function subscale consists of 17 items and is scored between 0-68. A high score indicates poor function, pain or stiffness.	Baseline and month 3
Secondary	Isokinetic muscle strength measurement Change from baseline in knee joint on the measuring the isokinetic muscle strength at month 3	Knee isokinetic muscle strength is measured with the Biodex System-3 isokinetic device . At 60° and 180° angular velocities, the range of motion was 90° flexion 0° extension, after three repetitions at each angular velocity; Measurements are made in a single set-five repetitions with 10 seconds of rest between repetitions	Baseline and month 3
