Controlled dynamic stretch orthoses

Summary

Postoperative knee stiffness and arthrofibrosis are common complications following knee surgeries. There is currently a range of conservative and surgical options for this, such as physiotherapy and manipulation under anaesthesia. Controlled dynamic stretch (CDS) orthoses are devices worn around the knee that contain an adjustable, spring-loaded hinge that apply a prolonged, dynamic stretch to the knee structures in order to stimulate growth of the contracted tissue and increase range of motion. It is proposed that CDS orthoses could reduce the need for surgical interventions, lead to shorter rehabilitation times, reduce the number of outpatient sessions required, and are suitable for home-based rehabilitation..

Health Technology Wales researchers searched for evidence on the clinical and cost effectiveness of CDS orthoses for postoperative knee stiffness and arthrofibrosis.

Based on the evidence identified, HTW’s Assessment Group concluded not to progress this topic to evidence appraisal.
