ACL reconstruction hamstring graft shows strong outcomes and fewer re-tears using preserved tibial insertion techniques.
When it comes to restoring knee stability after ligament injury, ACL reconstruction hamstring graft surgery remains a leading solution. In this article, we examine the technique that preserves the tibial insertion of the hamstring tendon, a method gaining traction among orthopedic surgeons.
The information presented here is drawn from the comprehensive systematic review and meta-analysis titled “Outcomes of hamstring graft with preserved tibial insertion for ACL reconstruction: systematic review and meta-analysis” published in the European Journal of Orthopaedic Surgery & Traumatology.

The ACL reconstruction hamstring graft protocol traditionally involves harvesting the semitendinosus and gracilis tendons and detaching them from their tibial insertion. However, newer approaches retain this tibial insertion, forming what’s known as a non-detached hamstring tendon (NDHT) graft.
Preserving the tibial insertion offers theoretical advantages:
The systematic review showed that NDHT protocols were applied in multiple configurations, but always with a preserved insertion. Surgeons adapted existing arthroscopic workflows to fit this refined technique. The ACL reconstruction protocol hamstring graft with preserved insertion often includes careful preservation of soft tissue during harvesting, precise tunnel placement, and dual fixation mechanisms.
In terms of ACL reconstruction hamstring graft recovery, the study reported encouraging outcomes. Patients receiving an NDHT graft experienced:
The ACL reconstruction hamstring graft rehab protocol doesn’t differ drastically from traditional recovery programs, but the biologically favorable conditions may support smoother progress. Some hypotheses suggest that proprioception and neuromuscular control could recover more naturally thanks to the preserved nerve fibers.
The ACL reconstruction rehabilitation protocol for hamstring grafts remains structured around milestones:
Notably, one finding highlighted that for an ACL reconstruction with hamstring graft, the recovery time may be positively influenced by improved early graft maturity, as shown on MRI by lower signal intensity at both 4 and 18 months.
The ACL reconstruction with hamstring graft technique has evolved thanks to biomechanical and imaging research. In the preserved-insertion approach:
The study also explored different surgical methods, including the arthroscopic ACL reconstruction hamstring graft and its compatibility with non-detached protocols. While technically more demanding, this technique can be safely executed by experienced surgeons.
MRI follow-ups showed more favorable signal-to-noise ratios in NDHT cases, supporting better graft ligamentization. This may be a key argument in favor of the ACL reconstruction using hamstring graft with preserved insertion.
Regarding the ACL reconstruction hamstring graft procedure, the review emphasized:
While promising, the technique is not without challenges. Some studies mentioned ACL reconstruction hamstring graft problems such as surgical complexity or variability in tunnel placements. However, these were not statistically significant compared to DHT protocols.
The meta-analysis highlighted:
When evaluating ACL reconstruction with hamstring graft rehab protocol, studies comparing DHT vs NDHT showed no statistically significant differences in function, but a favorable trend for NDHT in stability and imaging.
For patients undergoing ACL reconstruction surgery with hamstring graft, choosing a technique that retains the tibial insertion may represent a step toward better long-term outcomes. The review even reported that hamstring graft preparation for ACL reconstruction plays a crucial role in successful integration and recovery.
Current evidence suggests that preserving the tibial insertion in ACL reconstruction surgery hamstring graft techniques provides similar, if not better, outcomes than conventional detached methods. While further research is needed, particularly with longer follow-up durations, the NDHT approach appears promising for enhanced graft stability and integration.
