ACL Tear
Conditions
Brief summary
There is no consensus regarding the best surgical management of primary ACL tears. Recent evidence suggests that internal brace augmentation may increase load failure and therefore stabilize the graft in-situ at the time of ACL reconstruction. This prospective randomized controlled trial aims to compare the time to return to activity, and participant reported outcomes in participants with bone-tendon-bone ACL reconstruction with and without (control) internal brace augmentation.
Detailed description
Despite the wide variety of surgical approaches and grafts that can be used in an ACL reconstruction, graft failure and recurrent knee instability are nevertheless ubiquitous issues that have facilitated interest in ways to strengthen the graft at the time of surgery. While both animal and biomechanical models have strongly suggested improved graft strength and patient outcomes by utilizing suture tape augmentation in ACL reconstructions, there is scant clinical literature available to assess these extrapolations. A retrospective cohort study of 60 patients undergoing ACL reconstruction with a hamstring autograft or allograft (30 suture tape vs 30 no suture tape; mean age: 30), found shorter time to return to activity (9.2 months suture tape group vs 12.9 months no suture tape group; p=0.002), lower Western Ontario and McMaster University Osteoarthritis Indices (WOMAC) (2.2 suture tape group vs 6.2 no suture tape group; p=0.024), higher international knee documentation committee (IKDC) scores (87.6 suture tape group vs 73.2 no suture tape group; p=0.006), lower average pain on the national pain rating scale (NPRS) (0.6 suture tape group vs 1.66 no suture tape group; p=0.021) and no significant difference in range of motion in degrees (129 suture tape group vs 127 no suture tape group; p=0.46), knee injury and osteoarthritis outcome score (KOOS) (92.2 suture tape group vs 87.1 no suture tape group; p=0.68), or complications (13% suture tape vs 10% no suture tape; p\>0.05) at 2 years follow up. A retrospective cohort study of 108 patients undergoing ACL reconstruction with a hamstring autograft with and without suture tape reinforcement (36 suture tape vs 72 no suture tape; mean age: 25), found a significantly higher Tegner activity score (7.1 suture tape group vs 6.4 no suture tape group; p=0.026) but otherwise no significant difference in time to preinjury activity level (11.9 mos suture tape group vs 11.6 no suture tape group; p=0.59), range of motion (degrees) (136 suture tape group vs 137 no suture tape group; p=0.44) , Lysholm knee score (95.6 suture tape group vs 94 no suture tape group; p=0.165), IKDC score (94.4 suture tape group vs 93.8 no suture tape group; p=0.44), or complications (6% suture tape group vs 5% no suture tape group; p\>0.05) at 2 years follow up. A prospective cohort study of 50 ACL reconstructions with hamstring autograft with and without suture tape reinforcement (25 suture tape group vs 25 no suture tape group; mean age: 30), found a significant improvement in greater than 2 grades of Lachman testing from preoperative assessment compared to 6 months follow-up (68% suture tape group vs 32% no suture tape group; p=0.039) but no difference in Lysholm knee score at 6 months (87.0 suture tape group vs 87.0 no suture tape group; p=0.756). Moreover, none of the already-limited clinical data investigates the use of internal braces with bone-tendon-bone grafts, which are a popular choice for young adults and athletes. Furthermore, there are no current level 1 data on this subject. Therefore, this study aims to compare the time to return to pre- injury activity level, incidence of recurrent knee instability, and patient reported outcomes of patients treated with ACL reconstruction using bone-tendon-bone autograft with and without (control group) internal brace stabilization.
Interventions
PROCEDUREACL reconstruction with BTB autograft with internal brace augmentation (suture tape)
The ACL will be reconstructed using a participant's own patella tendon (BTB autograft), and the graft will be fortified by suture tape during the surgery in order to strengthen it.
PROCEDUREACL reconstruction with BTB autograft without internal brace augmentation (suture tape)
The ACL will be reconstructed using a participant's own patella tendon (BTB autograft). The graft will not be fortified by suture tape in this group. It will be used as is without any modification.
OTHERStandardized Rehabilitation Protocol
Participants will undergo a standardized rehabilitation protocol with twice weekly physical therapy
