Added value of ultrasound-guided percutaneous needle tenotomy over hydrodissection and physiotherapy in chronic lateral elbow tendinopathy: a pilot randomized controlled trial.

Aim Of The Study: There is no consensus on the most suitable non-surgical treatment of chronic lateral elbow tendinopathy. The aim of this pilot randomized controlled trial was to evaluate the size of effect of ultrasound-guided percutaneous needle tenotomy.

Material And Methods: Three intervention arms were formed: 1) percutaneous needle tenotomy, hydrodissection, and physiotherapy; 2) hydrodissection and physiotherapy; and 3) physiotherapy alone.

Late Onset Metallosis after Revision Total Knee Arthroplasty with Metal-Backed Patellar Component In Situ.

We describe a small case series with severe metallosis after revision total knee arthroplasty (TKA) due to metal-backed patellar component failure. Metallosis is a rare complication after TKA, which may cause systemic and local symptoms. In our cases, diagnosis of metallosis was supported by radiographic imaging and aseptic aspiration.
