Summary

Focused ESWT significantly improves the subjective Lysholm score , KOOS and reduces donor-site morbidity compared to non-ESWT group.

Abstract

【Purpose】The purpose of this study was to investigate the influence of repetitive focused extracorporeal shockwave therapy (ESWT) on clinical outcome and donor site morbidity after ACL reconstruction with Quadriceps Tendon Bone (QTB) autograft.
【Material and Methods】In this prospective controlled study, a total of 60 consecutive patients underwent primary ACLR using Quadriceps Tendon Bone (QTB) autograft performed by single surgeon (HF). Patients were randomized into two groups (ESWT group/n=30, control group/n=30). Patients in the ESWT group received focused shockwave therapy 3, 5 and 7 weeks after ACL surgery.To evaluate donor site pain, numerical rating scale (NRS) score was used.NRS, functional scores (Lysholm score and KOOS) and complication were assessed at 3 months (baseline), 6 months, and 9 months postoperatively.
Data were compared between the ESWT and control groups.
NRS, Lysholm score, and KOOS showed significant improvement in the ESWT group compared with the control group for all time-points (p < 0.01).
【Discussion】 In conclusion, focused ESWT significantly improves the subjective Lysholm score , KOOS and reduces donor-site morbidity compared to non-ESWT group.
