Adhesive capsulitis and disorders of the intra-articular portion of the long head of the biceps brachii tendon are common causes of shoulder pain. Sonographic findings, coupled with clinical evaluation and medical history, are paramount for prompt diagnosis. Herewith, either to precisely confirm the pain generator(s) or to appropriately treat relevant cases, ultrasound-guided interventions are often required in daily clinical practice. Targeting the anatomical structures involved in the aforementioned pathological conditions, we briefly describe some technical tips and tricks as regards ultrasound-guided hydrodilatation of the shoulder capsule at the rotator interval.

Total knee arthroplasty is a common and successful treatment modality for knee arthritis that is refractory to conservative management strategies. Over 600,000 arthroplasties are performed per year in the United States, and this number is expected to increase in the coming years. Unfortunately, 8% to 34% of patients experience chronic pain after having a total knee arthroplasty. ⋯ In this article, we outline the work-up of a painful total knee arthroplasty. Then we provide a thorough review of interventional pain management strategies and highlight the pertinent literature. Lastly, we hypothesize future developments in the field that may provide better outcomes for patients suffering from painful total knee arthroplasty.

Review Comparative Study
Longevity and Utilization Cost of Rechargeable and Non-Rechargeable Spinal Cord Stimulation Implants: A Comparative Study.
Despite major advancements in features and capabilities of the implantable pulse generator (IPG), real-life longevity and cost-effectiveness studies to guide pain specialists to make the appropriate choice between rechargeable and non-rechargeable IPG are limited. Our study aimed to compare the longevity and cost effectiveness of rechargeable vs. non-rechargeable IPG and SCS systems. ⋯ Rechargeable IPG had increased longevity compared to their non-rechargeable counterparts, yet there was no significant difference in the actual longevity due to premature revisions or explantations between both SCS systems. Furthermore, non-rechargeable SCS systems were found to be the more cost-effective option when compared with rechargeable SCS systems.
