Overview

Exploratory study examines tendon properties' impact on outcomes post-ACLR using BPTB autograft, indicating possible recovery correlations.

Key Points

  • To assess the relationship between patellar tendon structure and patient-reported outcome measures after ACL reconstruction with BPTB autograft.
  • Analyzed 34 individuals post-ACLR with BPTB autograft.
  • Conducted assessments at 1, 3-4, and 6-9 months after surgery.
  • Used B-mode ultrasound and shear wave elastography for tendon property measurements.
  • Applied simple and multiple linear regressions to evaluate correlations with PROMs.
  • Negative correlation between shear modulus at 1 month and ACL-RSI scores at 6-9 months (p = 0.022).
  • Positive correlation between viscosity at 3-4 months and TSK-11 scores at 6-9 months (p = 0.016).
  • Positive correlation between thickness at 6-9 months and KOS-ADLS scores at 6-9 months (p = 0.031).
  • No significant relationships found between involved limb properties and PROMs after adjusting for covariates.
