60 participants in 2 patient groups

High-intensity laser therapy

Active Comparator group

Description:

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 hotpack, which is used as a superficial heater, is applied to the knee area for 30 minutes, wrapped in two layers of towels. As analgesic current, conventional TENS is applied to the knee area for 30 minutes with 4 electrodes at 80 Hz frequency, 200 ms current duration. Flow intensity is adjusted according to the patient's tolerance, and the current intensity is increased as the patient's sense of current decreased in the following periods. HILT 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.

Treatment:

Other: high-intensity laser therapy

Other: sham high-intensity laser therapy

Sham high-intensity laser therapy

Sham Comparator group

Description:

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.

Treatment:

Other: high-intensity laser therapy

Other: sham high-intensity laser therapy
