Consent✅ - this is a beauty 🤓
Elite runner
Crampy, aching lateral knee pain - onset at around 20-30 mins
Seen multiple clinicians - had numerous injections including ITB plus extensive rehabilitation - refractory
Almost 'claudicant' in nature - settles quickly on cessation of exercise - spreads both proximal & distal to lateral joint line
No spinal symptoms & LSp assessment clear
No lateral compartment pathology eg meniscal tear
Had popliteus tendinopathy on US, but minimal response to my initial diagnostic injection
POCUS video -
The inferolateral genicular neurovascular bundle ('pepper pot' structure) is seen compressed under the distal ITB on active knee flexion : terminal extension
Patient localises pain in this area with probe pressure
Injection - hydrodissection (CSI, LA) - fluid seen separating plane just superficial to NV bundle
100% pain relief on extended treadmill test beyond 45 mins 👍
I wonder how many recalcitrant 'ITB' cases are actually neurovascular in aetiology? 🧐
Plan - considering angiography, MR neurography & possible distal ITB release at Gerdy's tubercle if not responsive to injection
