Abstract

Background: Appropriate graft tension and secure graft incorporation in bone tunnels are essential for successful anterior cruciate ligament (ACL) reconstruction using hamstrings tendon autografts. The WhipKnot™ soft tissue cinch, introduced by Smith and Nephew in 2004, is an alternative option to the commonly used whipstitch technique during preparation of the hamstring autograft in ACL reconstruction.

Aims: To investigate the effectiveness of the WhipKnot™ soft tissue cinch and technique during the preparation of the tendon graft for ACL reconstruction.

Method: A total of 33 ACL reconstruction operations performed between February 2011 and December 2011 were included in this study. These were performed by a single senior surgeon who used the Whipknot™ technique for the preparation of each graft. Four were used for each operation; two for each end of the harvested hamstrings tendons, including semitendinosus and gracilis tendons respectively.

Results: In total, 132 WhipKnots were used during the knee operations. Use of the WhipKnot™ technique resulted in successful graft preparations, tensioning and effective graft placement in the tibial and femoral tunnels in almost all instances. Only one case of WhipKnot™ failure (slippage) was recorded.

Conclusion: These results indicate that the Whipknot™ technique is a safe, reliable and practical option for the preparation of the hamstrings autografts.
