Summary

Background: Osteoarthritis (OA) is one of the most common joint diseases that most often causes physical disability. Physical therapy modalities, exercise programs and intra-articular injections are widely used in the treatment of OA. Purpose: The aim of this study is to investigate the effects of adding different exercise treatments to hyaluronan injection on proprioception, muscle strength and quality of life in patients with knee OA. Methods: A total of 54 patients were included in the study and were randomized into three groups. Quadriceps strengthening exercises were applied to the patients in Group 1, a home exercise program was applied to the patients in Group 2, and no exercise program was applied to the patients in Group 3. Additionally, all patients received patient education and intra-articular hyaluronic acid injection into the symptomatic knee. Standard forms were filled out to evaluate the patients' pain, functional status and quality of life. Muscle strength and proprioception were evaluated with an isokinetic dynamometer. Changes in the patients' walking parameters were evaluated by gait analysis. Evaluations were made at the beginning of treatment, at the end of treatment, and at the 3rd and 6th months of treatment.

Detailed description

Background: Osteoarthritis (OA) is one of the most common joint diseases that most often causes physical disability. The most common type of osteoarthritis with the highest incidence in the clinic is knee osteoarthritis. Physical therapy modalities, exercise programs and intra-articular injections are widely used in the treatment of knee OA. Purpose: The aim of this study is to investigate the effects of adding different exercise treatments to hyaluronan injection on proprioception, muscle strength and quality of life in patients with knee OA. Methods: A total of 54 patients with stage II and III primary knee OA were included in the study. The patients included in the study were divided into 3 groups by randomization. For randomization, envelopes containing the letters A, B and C were prepared for the patients included in the study. The patients included in the study randomly selected one of the envelopes. Patients who chose the envelope with the letter A were included in the 1st group, patients who chose the envelope with the letter B were included in the 2nd group, and patients who chose the envelope with the letter C were included in the 3rd group. The researchers who made the assessment measurements were unaware of which patient was in which group. Statistical analysis of the results was performed by a biostatistician who had no information about the therapies the patient groups received. Quadriceps strengthening exercises were applied to the patients in Group 1 with the isokinetic dynamometer device, a home exercise program was applied to the patients in Group 2, and no exercise program was applied to the patients in Group 3. Additionally, all patients received patient education and intra-articular hyaluronic acid injection (once a week, 3 times in total) into the symptomatic knee. Standard forms were filled out to evaluate the patients' pain, functional status and quality of life. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Lequesne knee index and The Health Assessment Questionnaire (HAQ) scales were used to evaluate the patients' functional status and quality of life. Visual Analogue Scale (VAS) was used to evaluate the pain conditions of the patients. Muscle strength and proprioception were evaluated with an isokinetic dynamometer. Changes in the patients' walking parameters were evaluated by gait analysis. Evaluations were made at the beginning of treatment, at the end of treatment, and at the 3rd and 6th months of treatment.

Conditions

• Knee Osteoarthritis

Interventions

Type	Name	Description
OTHER	Intra-articular hyaluronic acid injection	Hyaluronic acid was injected into the symptomatic knees of the patients a total of 3 times, once a week for 3 weeks. Injections were administered by the physician using a lateral approach with the patient lying on his back and the knee in full extension. After each injection, patients were warned to apply cold to avoid possible local reactions and not to overload for 24 hours. Hyaluronic acid preparation was in the form of 2.5 ml solutions obtained biotechnologically, containing 10 mg sodium hyaluronan in each milliliter. The hyaluronan in solution was of medium molecular weight (0.9 million daltons) but still lower molecular weight than the hyaluronan in normal healthy synovial fluid.
