Key takeaways:
- Revision ACL reconstruction with lateral extra-articular tenodesis had better outcomes vs. isolated revision ACL reconstruction.
- Patients with an isolated ACL reconstruction had increased rotational instability.
DENVER — Kostas J. Economopoulos, MD, discusses a study presented here that showed lateral extra-articular tenodesis may improve outcomes in patients with an intact graft and residual instability vs. revision ACL reconstruction alone.
Economopoulos, an assistant professor of orthopedics at Mayo Clinic Arizona, and colleagues retrospectively reviewed data from 47 patients with medial meniscal tears after ACL reconstruction and an intact or partially torn ACL graft with an exam consistent with residual or recurrent rotational instability. Researchers stratified patients based on whether they underwent lateral extra-articular tenodesis (LET) alone (n = 19), LET with revision ACL reconstruction (n = 12) or isolated revision ACL reconstruction (n = 16).
“We did find that the isolated LET and the LET with revision ACL reconstruction showed better patient-reported outcomes compared to those patients who had a revision ACL reconstruction on its own,” Economopoulos told Healio at the American Orthopaedic Society for Sports Medicine Annual Meeting.
Economopoulos said patients with an isolated revision ACL reconstruction had more rotational instability postoperatively compared with patients who received an LET.
“We think that using an LET in patients with residual rotational instability is a great option for these patients,” Economopoulos said. “And in some ways, an isolated LET is just as functional as doing a revision ACL reconstruction with an LET but avoids the complications and the morbidity associated with a revision ACL in a patient with an intact graft and a residual instability.”
