The Effectiveness of BETY in Knee Osteoarthritis With Intra-Articular Injections

Condition(s) studied

Investigational drug(s) / intervention(s)

BETY: Participants in this group will follow a traditional exercise program consisting of active range-of-motion exercises for the knee joint, isometric muscle strengthening, and stretching exercises targeting the lower extremity muscle groups.

Study summary

Osteoarthritis (OA) is the most common condition in middle-aged and elderly populations; it causes pain and physical disability and is characterized by cartilage degeneration, changes in bone tissue, inflammation of the synovial membrane, and an increased inflammatory response. Because pain and depression often co-occur in individuals diagnosed with OA, the concepts of disability and health-related quality of life caused by the disease have become more decisive than radiological joint damage. The chronic nature of the disease, like other chronic conditions, encompasses a range of biopsychosocial impacts, including pain, fatigue, sleep disturbances, functional loss, anxiety, depression, and social isolation. This complex structure is accompanied by a pattern in which inflammatory processes are triggered. Recently, intra-articular injections (such as Platelet-Rich Plasma Therapy (PRP), Hyaluronic Acid (HA), PRP+HA combinations, Corticosteroids, Prolotherapy, and Stem Cells) have been accepted as a treatment for OA. Regarding the mechanism of these intra-articular injections, it has been reported that a combination of various anabolic and anti-inflammatory cytokines may treat inflammation associated with the early stages of OA. It has been demonstrated that, through the effects of various growth factors, these treatments have a positive impact on chondrogenesis and mesenchymal stem cell proliferation by increasing anti-inflammatory mediators and reducing pro-inflammatory mediators.

Bilişsel Egzersiz Terapi Yaklaşımı - BETY (Cognitive Exercise Therapy Approach in english) is an exercise approach based on the biopsychosocial model. BETY consists of innovations in function-oriented body stabilization exercises (FoGSE), chronic pain management (BETY-Nociplastic Pain Management (BETY-NPM)), emotion-mood information management (dance therapy-authentic movement), and sexuality information management. The aim of this study is to investigate the effectiveness of BETY, which is often initiated following intra-articular injections-a treatment frequently chosen for individuals diagnosed with knee osteoarthritis (OA).

Eligibility

Primary outcome measure(s)

• BETY-BQ — 6 months
  The BETY-BQ was developed on rheumatic patients and was introduced to the literature as a standardized biopsychosocial measurement tool as a result of improving the definitions of recovery from patients with expert opinions and statistical analysis. Scoring of the scale is done using a 5-point Likert system, each item is scored between 0 and 4 points, and a high total score in the scale consisting of a total of 30 items indicates a high biopsychosocial impact.
• Muscle Strength — 6 months
  Muscle strength will be assessed using the Biodex System 3 Pro® isokinetic device (Biodex Medical Systems Inc., Shirley, NY, USA). Before the first assessment, participants will be recruited to a familiarization session. Each assessment will be preceded by a 10-minute warm-up walk and participants will perform knee flexor and extensor maximal concentric isokinetic muscle strength tests at angular velocities of 180°/s (10 repetitions) and 60°/s (5 repetitions) with a 30-second rest interval. Peak torque (PT) and average power (AP) will be recorded in Newtons (Nm) and watts (W) per meter.
