Effects of Exercise Versus Topical Agents on Knee Osteoarthritis

The Comparison of the Effectiveness of Exercise and Topical Agent Treatments in Knee Osteoarthritis: A Randomized Controlled Trial

Osteoarthritis, a chronic and degenerative joint disease, is the most common type of arthritis and affects more than 300 million adults worldwide. Osteoarthritis, which is characterized by joint pain and stiffness, has negative consequences for function, participation and quality of life, which are important components of health. The knee joint is the most common joint in terms of osteoarthritis and is more common in individuals over 50 years of age. There is no proven definitive treatment in today's literature for common osteoarthritis, which is one of the important causes of the global disease burden. However, since it is a progressive disease with varying degrees of severity, it is a chronic problem that requires long-term treatment. According to current clinical guidelines prepared by the working groups of the International Osteoarthritis Research Society (OARSI) and the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases ESCEO , treatment typically includes physiotherapy interventions with the use of non-steroidal anti-inflammatory drugs (NSAIDs) and analgesics, including intra-articular injections of corticosteroids; In more severe cases, joint replacement surgery is recommended. The aim of this research project is to examine the effectiveness of a supervised exercise program applied in combination with NSAID-specific topical agents, in comparison with groups receiving only topical agents or only exercise treatments.

Voluntary participants who have been diagnosed with knee osteoarthritis will be included in the study. Signed voluntary consent will be obtained from participants. Participants will be divided into tree groups. Study groups will be as follows: a) exercise, b) exercise & topical agent, c) topical agent.

Individuals with a diagnosis of knee osteoarthritis who underwent supervised exercise under the guidance of a physiotherapist for 6 weeks, 2 days a week.

Individuals with a diagnosis of knee osteoarthritis who had supervised exercise under the guidance of a physiotherapist for 6 weeks, 2 days a week, and in addition to this program, they used diclofenac gel 2 times a day, 4 days a week.

Individuals with a diagnosis of knee osteoarthritis using diclofenac gel twice a day, 4 days a week, for 6 weeks

Diclofenac gel application to the knee joint twice a day, four days a week, in addition to a supervised exercise program under the supervision of a physiotherapist for 6 weeks.

On this scale, "0" indicates the absence of pain, and "10" indicates the most severe pain imaginable (17). Patients will be asked to rate the severity of their knee pain with a number between 0 and 10 using this scale. The minimum clinically significant difference value (MCID) of this valid and reliable pain scale is 1.74 points.

WOMAC assesses the level of difficulty, pain and joint stiffness experienced by the patients during their physical functions. WOMAC score is a 5-point Likert-type scale, high scores indicate poor status and consist of a total of 24 questions.

For 40mHYT, patients will be asked to walk as fast as possible on a flat and hard surface, on a 10-meter marked walking path. Walking time will be measured in seconds with a stopwatch. The test will be repeated three times and the arithmetic mean of these measurements will be recorded as the result value. Considering the age range of the patients, it was planned to allow a one-minute rest period between retests.

Patients will be asked to climb 10 pre-marked 20 cm high steps as quickly as possible on a standard ladder. The test time will be measured in seconds with a stopwatch. The test will be repeated 3 times and the average value will be recorded in seconds. Similarly, in this evaluation, patients were given a one-minute rest period between 3 repetitions of the test.

During the assessments, three repeat measurements will be made using an electronic goniometer. For goniometric measurement, the pivot point will be placed on the lateral condyle of the femur. The fixed arm will be held parallel to the lateral midline of the femur. The movable arm will follow the movement of the fibula.

SF-12 is the abbreviated version of the SF36 Quality of Life Scale and is frequently preferred for ease of use. It has 2 components, physical and mental, scored between 0 and 50. A high score from the score indicates health-related well-being and increased quality of life, while a decrease indicates worsening.

It will be used to evaluate patient satisfaction. It is designed to determine the amount of improvement or worsening of the patient over time. In our study, GRC consisting of 5 levels between -2 and +2 value ranges (-2: I am much worse, -1: I am worse, 0: I am the same, 1: I am better, 2: I am much better) was preferred.
