Title : Short-term clinical and functional outcomes of all-inside ACL reconstruction surgery
Abstract:
Background: The role of the All-inside Anterior Cruciate Ligament (ACL) reconstruction technique remains dubious in several aspects. This study aims to report the outcome and complications of All-inside ACL reconstruction in a series of patients with an ACL tear.
Methods: In the current prospective study, fifty patients with a primary ACL tear treated with all-inside ACL reconstruction techniques were included. The grafts were harvested from the autologous semitendinosus muscle. Outcome measures were evaluated before and one year after the surgery including the Lachman test, Pivot-shift test, International Knee Documentation Committee (IKDC), and Lysholm scores. Quantitative evaluation of side-to-side anterior tibial translation was performed using a KT-1000 arthrometer.
Results: The Lachman test and Pivot shift test were significantly improved after the operation (p<0.001, p<0.001, respectively). The mean postoperative IKDC score was 96.1±7.1 (range 70-100). According to the Tegner Lysholm knee scoring scale, the knee functions were excellent, good, and fair in 44 (88%), 3 (6%), and 3 (6%) patients, respectively. The mean side-to-side difference of anterior tibial translation was 1.1±1 mm. A significant positive correlation was found between the IKDC scores and the number of physiotherapy sessions (r=0.504, p<0.001). No graft failure was observed. Two patients had knee laxity on the final examination.
Conclusion: All-inside ACL reconstruction results in significant improvement in the objective outcomes and has acceptable subjective results.
