Participants in group 2 will receive MWM technique treatment 3 times a week for 4 weeks. The patient should lie face down with a pillow over the knee and the physiotherapist should stand on the contralateral side for the application. The physiotherapist passes the belt around the waist to the patient's tibia edge. The knee is stabilized with one hand while the leg is supported with the other hand. The knee is moved medially without applying too much force through the belt and the patient is asked to stretch. If there is no pain, the movement is indicated. If pain occurs during the movement, the same procedure is performed for the lateral side by changing the position. It is important that the arch remains horizontal and does not cause rotation of the hip. The movement will be repeated 3 times at the point where there is no pain.

Participants in group 1 will receive conservative treatment 3 times a week for 4 weeks. Conservative treatment includes hot packs and traditional transcutaneous electrical nerve stimulation (TENS), an electrotherapy.

All participants in the study will receive 20 minutes of hot pack application to the knee area each session by a physiotherapist. All participants in the study will receive TENS for 20 minutes each session from the physiotherapist, who will place personalized electrodes around the knee joint and adjust the current to the level the person can tolerate.

Mobilization Technique

VAS, which digitizes parameter values that cannot be measured numerically, was used to evaluate the pain intensity of the participants. The two extreme values of the parameter to be measured are written on the scale as 0 and 10. The person is asked to mark the value that best suits him/her on the scale. For pain, no pain and very severe pain; It is specified as 0 and 10. The person chooses a value according to his/her pain

SF-36, developed in 1992, consists of 36 items providing measurement to the following 8 dimensions: physical functioning (10 items), social functioning (2 items), role limitations due to physical problems (4 items), role limitations due to emotional problems (3 items), mental health (5 items), energy/vitality (4 items), pain (2 items), and general health perception (5 items). An increase in the score indicates a higher rate of improvement in health status.

This survey is conducted to evaluate how much the routine activities in the participants' lives are affected by the knee problem. The survey included the following parameters: pain, physical function, and stiffness. A Likert system ranging from 1 to 5 is used. As the value increases, the intensity of the parameters increases

To assess the participants' sense of proprioception, the method of actively reproducing the passive position without supporting the limb was used. In this assessment, where the angle is measured with a goniometer, the person closes their eyes. The limb is passively moved to the target angle and the person is asked to concentrate on the position. After 10 seconds, the starting point of the movement is returned. The person tries to find the target angle by actively moving the same limb. If the angle achieved at the end of the movement is different from the target angle, the difference is recorded as the deviation angle (used to 15° and 45° knee flexion).
