Knee Osteoarthritis and Rehabilitation

May 22, 2024 updated by: METEHAN YANA, Karabuk University

Knee Osteoarthritis and Lazer Therapy

Osteoarthritis (OA) is a chronic degenerative disease of articular cartilage that causes hypertrophic changes in bone. OA is a non-inflammatory progressive musculoskeletal disease and is one of the most common degenerative diseases in the general population. OA is characterized by progressive cartilage destruction in load-bearing joints, subchondral sclerosis, osteophyte formation, and some biochemical and morphological changes in the synovial membrane and joint capsule. Common symptoms of knee osteoarthritis are; Knee pain that increases with activity, limitation of normal joint movement of the knee, edema, and knee pain that begins with prolonged sitting.

The aim of this study is to evaluate the effects of laser treatment applied in addition to conventional physiotherapy on pain, function, muscle strength and balance in patients with knee osteoarthritis who received PRP.

Detailed Description

OA is a non-inflammatory progressive musculoskeletal disease; damage begins in the cartilage and causes changes in the joint structure over time. Although intra-articular injection approaches have been frequently used in the treatment of OA recently, intra-articular injections known as Platelet Rich Plasma (PRP) have also started to be used frequently. Today, the areas of use of laser therapy have increased. When the laser beam is applied, it is absorbed by the tissue or scattered back. Laser has photochemical, thermal and ionizing effects on tissues. Laser has an analgesic effect by increasing endorphin synthesis and reducing C nerve fiber activation. Laser indirectly increases microcirculation by increasing temperature in the tissue. Although there are various studies on treatment options for OA in the literature, no studies have been found to investigate the effectiveness of laser treatment applied in addition to conventional treatment after PRP. In our study, we aimed to evaluate the effects of laser treatment applied in addition to conventional physiotherapy on pain, function, muscle strength and balance in patients with knee osteoarthritis who received PRP.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Conventional treatment
Within the scope of conventional treatment, individuals were given Transcutaneous Electrical Nerve Stimulation (TENS), infrared, US and exercise therapy.
In the study group, low-dose laser treatment was applied in addition to conventional treatment. Chattanoga Group Therapeutic Laser device was used for laser treatment. Laser treatment was applied to 8 sensitive points around the knee for 1 minute, for a total of 8 minutes. Laser treatment was applied continuously, with a wavelength of 830nm and a power of 6J.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pain severity
Time Frame: Baseline and 2 weeks post-intervention
Knee pain severity will measured using the Visual Analog Scale. Scale (VAS). The VAS is a 10 cm scale, where 0 represented no pain and 10 represented unbearable pain. Pain intensity was recorded by measuring the point marked between 0- 10.
Baseline and 2 weeks post-intervention
Function
Time Frame: 2 weeks post-intervention
WOMAC will be used to evaluate the degree of physical function. This scale has a total of 24 questions and 5 answers between 0-4 for each question. A high score indicates that the symptoms are severe.
2 weeks post-intervention
MUSCLE STRENGTH
Time Frame: Baseline and 2 weeks post-intervention
Hip, knee flexor and extensor muscle strengths will be measured using a manual dynamometer.
Baseline and 2 weeks post-intervention
BALANCE
Time Frame: Baseline and 2 weeks post-intervention
Dynamic balance of individuals through the Modified Star Balance Test will be evaluated.
Baseline and 2 weeks post-intervention
