Summary

Osteoarthritis, the most common type of arthritis, is a chronic and degenerative joint disease. It has been reported to affect more than 300 million adults and elderly individuals worldwide. The joint most commonly affected by osteoarthritis is the knee joint and this condition is called gonarthrosis. The goal of treatment is to reduce symptoms and ultimately slow the progression of the disease with various treatment options throughout the course of the disease.Current clinical studies 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) According to the guidelines, treatment typically includes physiotherapy interventions with the use of non-steroidal anti-inflammatory drugs (NSAIDs) and analgesics, including intra-articular injections of corticosteroids. Exercise-oriented physiotherapy is one of the main approaches for the conservative treatment of gonarthrosis. The curative clinical effect of exercise therapy on pain and functional disability in gonarthrosis is important. The use of PRP in the treatment of gonarthrosis is based on the ability of platelets to release biologically active proteins and promote tissue healing. Since the cartilage tissue mainly affected in gonarthrosis has low healing potential, this feature of platelets becomes more important for the target tissue. Existing studies show that PRP is superior to hyaluronic acid in intermediate and initial gonarthrosis; on the other hand, less satisfactory results are reported in severe gonarthrosis, similar to viscosupplementation. Topically or orally administered NSAIDs form the backbone of pharmacological treatment in gonarthrosis. It is seen that both exercise, PRP and topical NSAID agents are among the recommendations in the treatment of gonarthrosis. However, there is insufficient evidence regarding the superiority and therapeutic efficacy of these three treatment approaches. The aim of this study is to determine the effectiveness of "exercise", "PRP" and "NSAID-specific topical agents" in the treatment of patients with gonarthrosis; pain, function, quality of life, and patient satisfaction.

Detailed description

Voluntary participants who have been diagnosed with gonarthritis 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) topical diclofenac, c) platalet-rich-plasma (PRP).

Conditions

• Gonarthrosis

Interventions

Type	Name	Description
OTHER	Exercise	The first 3 weeks of the exercise program will include range of motion exercises, isometric and isotonic strengthening exercises for the muscles around the knee and hip, and stretching exercises. In the following 3 weeks, resistance strengthening exercises and closed kinetic chain exercises will be added to the program.
OTHER	Topical Diclofenac	They will apply it around the knee joint 4 days a week, 2 times a day (every 12 hours), morning and evening for 6 weeks.
OTHER	Platelet-Rich-Plasma (PRP)	8 ml of blood will be taken from each patient in tubes containing 0.9 ml of 3.2% sodium citrate. Swing-out rotor (open-swing type) will be placed in the centrifuge with the tubes facing each other. After centrifugation, 2.5 cc of PRP product will be collected from each tube and the resulting PRP will be administered to patients by injection under sterile conditions.
