Anatomic double-bundle ACL reconstruction with notchplasty improved anterior stability, and no harmful effects were found on patellofemoral joint findings, according to study results.
Researchers classified 73 patients who underwent anatomic double-bundle ACL reconstruction without notchplasty as the control group and 64 patients with 2-mm notchplasty as the notchplasty group. All patients were evaluated using loss of extension, patient’s subjective feeling of limited extension and pain at passive full extension, muscle strength, manual laxity tests, KT-1000 arthrometer measurement, patellofemoral joint findings, Tegner score, Lysholm score, subjective scores and time to return to sports.
The researchers also recorded tearing of the reconstructed ACL and additional synovectomy and measured both tibial and femoral tunnel positions using Rosenberg and lateral view radiographs.
Compared with controls, study results showed loss of extension and the feeling of limited extension were larger in the notchplasty group. Due to prolonged loss of extension, six patients in the notchplasty group required additional synovectomy compared with no patients in the control group.
Although the KT-1000 arthrometer measurement was better in the notchplasty group, six patients in the notchplasty group showed an over-constrained knee vs. one patient in the control group.
No between-group differences were found regarding muscle strength, patellofemoral findings, Lysholm score, Tegner score, subjective scores, time to return to sports, and other manual laxity tests or tunnel positions, according to the researchers.
