Lasts Longer

A study published in the Journal of Bone & Joint Surgery compared normal corticosteroid injection with the extended-release suspension available at Primary Spine & Rehab.1 They treated 228 patients who had moderate to severe knee osteoarthritis. The extended-release injections provided quick pain relief, and compared to traditional corticosteroid injection, the pain relief was significantly better at weeks five through twelve. Measures of function and ability were also improved.

Ultrasound-Guided Injections
Ultrasound for guided joint injections

We use ultrasound guidance to ensure the accuracy of injections. When corticosteroid injections are not accurate, they can worsen pain. Even in expert hands, no matter how confident the doctor is, studies show that guiding injections by touch and feel has accuracy ranging from 27% to 68%.2 The accuracy of ultrasound-guided injections, on the other hand, ranges from 70% to 94%. Compared to traditional injection techniques, ultrasound-guided injections have achieve greater pain relief - in some cases three times more pain relief on patient-rated numeric scales.

Exercise Therapy

Our extended-release corticosteroid injections can create fast pain relief that lasts for months, but it's important to note that these treatments do nothing to address the underlying problem. In addition to improving the pain, we need to improve how the body area functions to prevent or minimize future damage to the joint. Primary Spine & Rehab stands out as an excellent choice for joint pain, because we offer fast, lasting, non-surgical relief, along with viscosupplementation, exercise therapy, and other treatments that can improve joint function.
