Additive positive effects of kinesthesia and balance exercises in knee OA have been demonstrated. Used in clinical applications, they should be able to increase the functional capacities of patients. Long-term studies about efficacy and cost-effectivity of these exercises are needed.

Group exercise in hospital may be more effective than home-based exercises at reducing impairment associated with ankylosing spondylitis.

Dry needling appears to be an effective treatment method in relieving the pain and tenderness of myofascial trigger points.

Further data pertaining to other countries would be interesting to uncover whether ethnic differences also affect cartilage thickness. Collaborative use of MSUS seems to be promising in this regard.

Objectives The 3 aims of the work were to identify population subgroups that can benefit the most from viscosupplementation (VS), to provide recommendations on injection techniques, and to discuss VS appropriateness in clinical situations that are commonplace in daily practice. Methods The task force members voted on their degree of agreement on 27 statements, 36 recommendations, and 22 clinical scenarios using a 9-point scale. The strength of agreement/appropriateness/recommendation (SOA/SOR) was classified as strong if the median agreement score was ≥8. The level of consensus (LOC) was also obtained. Results Among the assumed predictors for VS failure, obesity, radiographic severity, large synovial fluid effusion, severe patellofemoral involvement, major malalignment, and gross joint instability received a large majority of agreements. The lateral mid-patellar approach was recommended for knee injection. Imaging guidance was unanimously recommended for hip and ankle. Agreement was achieved to strictly respect the dosing regimen proven by controlled trials. There was agreement for treating with VS patients with mild to moderate knee and hip OA, with normal weight or moderate overweight, insufficiently improved by first-line therapies, or who do not wish get oral treatment or who have contraindications to pain killers. The group considered the patient's wishes as a key element in therapeutic decision making. Conclusion Based on literature data and clinical experience, the EUROVISCO group proposed a set of recommendations for optimizing the results of VS, aimed to help practitioners, especially in some cases in which the patients' specificities make the therapeutic decision difficult.
