Abstract:
Aim: To evaluate the clinical response to augmenting ultrasound-guided tenotomy (USGT) with an amniotic membrane (AM) allograft injection. Design: Retrospective study. Materials & methods: Subjects underwent either a USGT (N = 16) or a combined USGT plus AM injection (N = 14). Results: Both groups demonstrated a significant reduction in pain from baseline starting after 2 weeks in the USGT plus AM group (p = 0.036) and after 8 weeks in the USGT group (p = 0.021). The reduction in pain was sustained for the entire duration of the study (52 weeks). There was no significant difference in pain levels at 26- or 52-week follow-up or patient satisfaction between the two groups. Conclusion: USGT with or without AM allograft injections results in a significant reduction in pain with high patient satisfaction.
