Detailed Description
Patients admitted to Istanbul University, Istanbul Faculty of Medicine, Department of Physical Medicine and Rehabilitation Outpatient Clinic with a diagnosis of knee osteoarthritis and who meet the inclusion criteria will be included in the study. Patients will be informed verbally and in writing about the purpose, duration and method of the study and will be asked to sign an "Informed Consent Form" after their consent is obtained.
In our study, the investigators aimed to evaluate the effects of dextrose prolotherapy and PRP injections in patients with chronic knee osteoarthritis. The duration of the study was determined as 8 months and it was planned to include 28 patients for each group to be randomized by computer program according to the order of application and 84 patients in total.
Patients who meet the inclusion and exclusion criteria will be randomized into 3 groups and the first group will receive Dextrose Prolotherapy and home exercise program, the second group will receive Platelet Rich Plasma injection and home exercise program, and the third group will receive saline injection and home exercise program.
After the application, patients will be questioned in terms of side effects and complications.
History and demographic characteristics such as age, gender, height, weight, marital status, educational level and occupation will be questioned, and medical history such as history of comorbidities and treatment approaches will be determined. In the physical examination, knee tests (ROM measurements, ligament tests, meniscus tests, tests for osteoarthritis) will be performed and TUG (Timed Up and Go) Test will be evaluated. Direct knee radiographs will be evaluated according to Kellgren-Lawrence Gonarthrosis Staging. The average and maximum level of pain during activity, at rest and at night will be questioned with the Visual Analog Scale (0-10 points). WOMAC pain score and WOMAC total scores will be questioned. Isokinetic muscle strength and proprioception will be evaluated with Biodex Isokinetic Dynamometer in our clinic. Functional status will be evaluated with Euro-Qol Quality of Life Scale. The evaluations will be performed by the researcher who is blinded to the applications.
Assessments will be made before treatment, 1 month, 3 months and 6 months after treatment.

Outcome Measures
Primary Outcome Measures
- Change from baseline pain score at 1-months, 3-months and 6-months [Baseline, 1-month, 3-month, 6-month]
Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) measures knee pain, stiffness, and physical function. The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function. The sum of the scores for the three subscales gives a total WOMAC score. High scores are associated with more pain, stiffness, and poor function, while low scores indicate well-being.
Secondary Outcome Measures
- Change from baseline stiffness and physical function at 1-months, 3-months and 6-months [Baseline, 1-month, 3-month, 6-month]
Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) measures knee pain, stiffness, and physical function. The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function. The sum of the scores for the three subscales gives a total WOMAC score. High scores are associated with more pain, stiffness, and poor function, while low scores indicate well-being.
- Change from baseline activity pain score at 1-months, 3-months and 6-months [Baseline, 1-month, 3-month, 6-month]
Visual Analogue Scale-Activity pain (0-10 point). Higher scores mean a worse outcome
- Change from baseline rest pain score at 1-months, 3-months and 6-months [Baseline, 1-month, 3-month, 6-month]
Visual Analogue Scale-Rest pain (0-10 point). Higher scores mean a worse outcome
- Change from baseline night pain score at 1-months, 3-months and 6-months [Baseline, 1-month, 3-month, 6-month]
Visual Analogue Scale-Night pain (0-10 point). Higher scores mean a worse outcome
- Change from baseline quality of life at 1-months, 3-months and 6-months [Baseline, 1-month, 3-month, 6-month]
The EuroQOL (EQ-5D-3L) scale is a scale developed to assess health-related quality of life and consists of two parts. The first part describes the health profile in 5 dimensions (mobility, self-care, social life, pain and psychological state). Each dimension includes 3 statements according to the degree of difficulty (1- some problem; 2-moderate; 3-much problem), the second part includes a visual analog scale (VAS) in which respondents rate their current health status from 0 to 100.
- Change from baseline functional balance at 1-months, 3-months and 6-months [Baseline, 1-month, 3-month, 6-month]
Timed Up and Go test requires the person to stand up from a standard chair in which they are sitting, walk 3 m at a comfortable speed to the marked place on the floor, turn around, walk backwards to the starting point and return to the sitting position in the chair. The time taken for the person to complete the test is measured in seconds. The timing of the test is related to the function.
- Change from baseline muscle strength and proprioception at 3-months and 6-months [Baseline, 3-month, 6-month]
Isokinetic muscle strength and proprioception will be evaluated with Biodex Isokinetic Dynamometer
