IBISG Summary
This Editorial Commentary examines the clinical and biomechanical evidence supporting suture tape augmentation of posterior cruciate ligament reconstruction. The authors discuss its potential role in reducing persistent postoperative laxity by providing load-sharing support to the reconstructed graft during rehabilitation and healing.
Key Findings
The evidence discussed suggests that suture tape augmentation may reduce clinical and radiographic laxity and improve return to previous activity levels compared with PCL reconstruction alone. Biomechanical studies have also reported increased load to failure and reduced graft elongation. However, existing clinical studies have limitations, and improvements in patient-reported outcomes and graft failure rates have not been demonstrated consistently.
Why This Research Matters
Persistent laxity remains a recognised concern following posterior cruciate ligament reconstruction. Suture tape augmentation may protect the graft from excessive loading while allowing the graft and tape to share load rather than completely shielding the graft. The commentary supports its use but also highlights the need for appropriately powered randomised clinical trials before definitive recommendations can be made.
