Relaxin Influences Knee Laxity Changes Across the Menstrual Cycle: 2431 Board #4 June 2 9

RESULTS: Pain at exercise (on a visual analogue scale 0-10) was reduced from 6±2 to 2±2 at six weeks and 1±1 after 12 weeks of treatment. Morning stiffness was reduced at six weeks by 56% and 87% after 12 weeks. The degree of neovascularisation in PowerDoppler ultrasound was reduced from Öhberg degree 3+ to 0-1+ after 12 weeks as was the tendon diameter by 38% in grey scale ultrasound. VISA-P scores improved by 32% at six weeks and 51% at 12 weeks. Players were able to return to sport at mean 18±12 days after initiation of the weekly therapy. CONCLUSIONS: Combined focused shockwave & low level laser tendon therapy accompanied by daily eccentric training are able to improve patella tendon function with a sustained effect in soccer athletes with an early return to game play.
