The impact of orthotic therapy on instability and functional improvement in knee joint disease - A Systematic Review

Abstract

Abstract Purpose Joint instability is a common joint dysfunction and a cause of musculoskeletal disorder and pain after anterior cruciate ligament injury and osteoarthritis. The aim of this literature review is to review the existing evidence regarding the impacts of knee brace in persons with joint instability, or laxity after knee disease concerning physical and functional outcomes. Methods A systematic search was performed at MEDLINE, Central Register of Controlled Trials (CENTRAL), PubMed, and PEDro and Web of Science databases until April 2, 2022, with their language limited to English. Studies to be included were randomized controlled trials (RCTs), controlled clinical trials, and controlled experimental studies that included comparison of interventions and no interventions testing effectiveness of orthotics in joint instability symptom patients Results Total 250 studies were retrieved and 12 articles met the inclusion criteria. Beneficial effects of knee braces appear to vary with disease. Self-reported instability may be improved with orthotics, while its effects are unclear in an objective assessment of joint instability. However, improved subjective instability lead to improved physical function. Conclusion Our aim is to provide information to both healthcare professionals with updated and high-quality recommendations for the management of instability joint condition. It is concluded that orthotic therapy may have a certain effect on subjective evaluation in joint instability.
