Pes Anserine bursitis

Had pes anserinus in right knee for 3 months now. Been diagnosed + had an ultra sound scan showing it as mild bursitis. Left knee shows the same, but no pain in that one. The condition slowly buikt up for months leading up to my current state. Had physio and doing on going stretches etc...but still not right and today lifted something and the pain has come back with a vengeance. I've had enough of the loss of mobility and booked myself in for a cortisone injection under ultra sound into the bursa sack to try to relieve the pain. Is this a good idea?

Hi Graham - yes, as long as you’ve failed at doing decent rehab/physio. Steroids get a pretty bad rap (deservedly so) when injected into joints but into soft tissue like bursa it’s seen as a means to an end. The steroid acting life is only 2 weeks at best but the pain relieving effect will last for much longer. However you will need to get to grips with why you got (bilateral) PB and make sure you address the cause and not just get rid of the symptoms. Might be worth trialing some orthotics, no stretches and some decent gluteal based rehab for hip control and not knee function. The Guru
