Harnessing the Power of Water: A Scoping Review of Hydrokinesiotherapy as a Game-Changer in Knee Osteoarthritis Management

Abstract

Background: Knee osteoarthritis (OA) is a prevalent condition that significantly impairs pain, mobility, and quality of life. Hydrokinesiotherapy, a water-based exercise therapy, is gaining traction as a potential alternative to traditional land-based rehabilitation for managing knee OA symptoms. Methods: This scoping review aimed to evaluate the effectiveness of hydrokinesiotherapy compared to standard land-based physical therapy and self-administered exercise regimens in improving pain, joint mobility, quality of life, and physical function in patients with knee OA. Five randomized controlled trials (RCTs) were included, assessing outcomes using measures such as the WOMAC score, Visual Analog Scale (VAS), and SF-12. The studies were critically appraised using the PEDro scale and the RoB-2 tool to determine the quality and risk of bias. Results: Hydrokinesiotherapy consistently demonstrated superior outcomes in pain reduction, joint mobility, and physical function across all studies. Patients in the hydrokinesiotherapy groups reported significant improvements in pain and mobility, which were strongly associated with enhanced quality of life. The review also highlighted the potential for hydrokinesiotherapy to serve as an effective alternative or complement to land-based exercises, particularly in populations experiencing severe symptoms. Conclusions: Hydrokinesiotherapy is an effective intervention for managing knee OA, offering significant improvements in key clinical outcomes. Given its benefits, hydrokinesiotherapy should be considered a valuable addition to knee OA treatment protocols. However, further research is needed to confirm long-term effects and to explore ways to improve accessibility to this therapeutic option.
