Background:
The debate continues regarding the best way to manage partial anterior cruciate ligament (ACL) tears.
Objectives:
To prospectively compare the clinical outcomes of remnant-preserving augmentation (RPA) and double-bundle reconstruction (DBR) in patients with ACL tears.
Methods:
In this prospective study, we included 13 cases of RPA and 30 cases of DBR with a follow-up period of 6 months, 12 months and 24 months. We clinically compared the preoperative and postoperative range of motion, Knee Society Score (KSS), Visual Analog Scale (VAS), Lysholm score, Tegner activity score, Short Form Health Survey (SF-36), thigh and calf circumference and anterior translation (Using the KT-1000 knee arthrometer).
Results:
There were no significant differences in Lysholm score, Tegner score, VAS or KSS within the two groups at any time. The KT-1000 arthrometer results were higher in the RPA group at 6 months than in the DBR group; however, it did not reach statistical significance.
Conclusions:
We found no significant differences between the two specific groups leading us to believe that RPA may play a role in reconstruction when only a single bundle is injured.
