Background. Researchers have investigated changes at the donor site for hamstrings and patellar tendons to be consistent with regeneration in anterior cruciate ligament reconstruction (ACLR). Recently free quadriceps tendon has emerged as a potential autograft for ACLR. The objective of this study was to investigate the changes at the quadriceps tendon (QT) donor site after primary ACLR by serial ultrasound.
Methods. The donor site was studied preoperatively, 2 weeks and 6 months postoperatively by serial ultrasound in 16 patients who underwent ACLR using QT autograft. QT structure, length, width, and thickness were studied at 1, 3 and 5 cm from the superior pole of the patella.
Results. There was no difference in thickness of QT preoperatively and 6 months postoperatively. But the mean thickness of QT changed postoperatively from 0.9, 1.0 and 1.0 mm at 2 weeks to 5.1, 4.9 and 4.6 mm at 6 months, which was significant. There was a difference in mean width at 6 months postoperatively (22.8, 21.5 and 20.9 mm) compared to preoperative (24.3, 24.6 and 23.5 mm) and 2 weeks postoperative (24.4, 24.0 and 23.6 mm) measurements. There was no change in length (L) of the QT between times frames. The central third of QT regained its uniform echogenicity and punctate appearance 6 months postoperatively in all cases.
Conclusion. The ultrasonography findings at the donor site are consistent with regeneration, but further imaging and histological examination are required to verify morphology and quality of regenerate.
