Objective: To identify and analyse existing data regarding knee ultrasound (US) feasibility in clinical practice. Material and methods: A systematic literature review was performed using the terms: (“knee”) AND (“ultrasound” OR “ultrasonography”) AND (“feasibility” OR “pilot” OR “proof of concept”). Feasibility studies regarding knee US or US aided maneuver involving knee joint, published during 2005-2015, were selected and evaluated against a complex framework constructed around mandatory key areas for feasibility studies: acceptability, demand, implementation, practicality, adaptation, integration and expansion. Results: One hundred and fifty-nine publications were identified, of which 9 were included in the final analysis: 6 dealt with the development and implementation of novel US scores, while the rest focused on implementing MSUS in clinical practice, evaluating the usefulness of articular cartilage US assessment and the feasibility of sonography for intra-articular knee injections, respectively. Six studies quantified feasibility as time spent for the evaluation, with only two addressing areassuch as acceptability, implementation and practicality, although none of these systematically assessed all feasibility domains. Conclusion: Knee US feasibility is still poorly addressed; the time required for US assessment is the main area addressed. This information gap should be properly addressed in future works, in order to ensure the right place for this technique.
