Primary ACL repair using Ligamys

What is it about?

A retrospective study was performed on prospectively collected data of 26 patients (28 ± 9 years, range 18–50 years; male/female = 17:9) who underwent biologically augmented ACL suture using dynamic intraligamentary stabilisation (DIS) device (Ligamys, Mathys, Switzerland) for ACL tear in an university-a liated specialised knee clinic. For clinical assessment, the Tegner and Lysholm score as well as IKDC score were used. KT-1000 or rolimeter arthrometer was used for assessment of anterior laxity forIKDC. Categorial values of anterior laxity were noted. Radi- ological follow-up consisted of weight-bearing anterior–pos- terior and lateral radiographs. In addition, adverse events such as ACL failure, arthro - brosis, pain > 3 on a visual analogue scale as well as need for and type of revision surgery was noted.

Why is it important?

Most of the clinical outcome studies dealing with ACL repair are from the developer’s perspective. It is a fact that these developer-initiated studies tend to interpret the results rather in favour than against their developed tech- nique or product. Hence, it was the purpose of the present independent investigator-initiated study to investigate the clinical and radiological outcomes as well as failure rate of patients who underwent an ACL suture using dynamic intraligamentary stabilisation device in a specialised inde- pendent knee clinic.

ACL suturing using the dynamic intraligamentary stabilisation device showed satisfying clinical results at 12-months follow-up. However, a retear rate of 15% and a reoperation rate of 35% due to retear or arthro brosis appear rather high. These results highlight the importance of adequate patient selection and the delicacy of the surgical procedure.
