Anterior Cruciate Ligament (ACL) Reconstruction Augmented With Bone Marrow Concentrate, Demineralized Bone Matrix, Autograft Bone, and a Suture Tape (The Fertilized ACL).

ABSTRACT:

Purpose

To examine the early clinical outcomes as well as safety of the Fertilized anterior cruciate ligament (ACL) reconstruction procedure.

Methods

A total of 16 consecutive patients with a mean age of 24 years (range, 16-45 years), who had been treated with the fertilized ACL were evaluated and followed over 2 years. Four patients underwent reconstruction using an FGL GRAFTLINK allograft (LifeNet Virginia Beach, VA) and 12 using quadriceps autografts. All patients received the fertilized ACL as previously described using bone marrow composite, demineralized bone matrix, and an internal brace (Arthrex, Largo, FL). Clinical outcomes at 2 years including International Knee Documentation Committee and Marx scores were evaluated. Complication rates, including return to operating room, arthrofibrosis, infection, and rerupture rates, were also assessed.

Results

All patients were followed for 6 months and all were released to full activity. In total, 11 of 16 patients were available for 2-year follow-up after the fertilized ACL reconstruction. At 2 years, the average International Knee Documentation Committee and Marx scores were 81 (standard deviation, 5.9) and 9 (standard deviation, 5.7), respectively. One patient required a return trip to the operating room for manipulation under anesthesia. No reruptures were observed at the 2-year mark. Nine of 11 patients had returned to their preinjury activity status at 2 years.

Conclusions

The fertilized ACL, which adds biology and an internal brace to an ACL reconstruction, is a reliable and safe option when performing an ACL reconstruction. Very low complication risks were seen in this consecutive series followed for 2 years. Patients consistently returned to their preinjury activity status.

Project description:PurposeTo compare the (1) rates of complications and reoperations, (2) rate of anterior cruciate ligament (ACL) graft failure, and (3) patient-reported outcomes (PROs) among patients after hamstring autograft ACL reconstruction (ACLR) with and without independent suture tape reinforcement at a minimum 2-year clinical follow-up.MethodsWe performed a 1:2 matched-cohort comparison of patients who underwent hamstring autograft ACLR with and without independent suture tape reinforcement between July 2011 and July 2017. Patients were matched according to age, sex, body mass index, preinjury Tegner activity score, and concomitant meniscal injury. Medical records were reviewed for demographic characteristics, additional injuries, and concomitant procedures. PRO scores (including Tegner activity, Lysholm, and International Knee Documentation Committee scores) and physical examination findings were collected both preoperatively and at a minimum of 2 years postoperatively.ResultsOverall, 108 patients who underwent ACLR were included: 36 patients (mean age, 25.3 years; range, 13-44 years) with independent suture tape reinforcement and 72 patients (mean age, 24.9 years; range, 13-54 years) without suture tape reinforcement. Overall, 5 of 36 suture tape patients (14%) and 10 of 72 control patients (14%) underwent reoperations. At an average follow-up of 26.1 months in the suture tape cohort and 31.3 months in the control cohort, 1 patient in the suture tape cohort and 4 patients in the control cohort experienced graft failure. There were no statistically significant differences between the suture tape and control groups regarding return-to-sport rate (89% and 88%, respectively), postoperative International Knee Documentation Committee score (94.4 and 93.8, respectively), and postoperative Lysholm score (95.6 and 94, respectively). There was a statistically significant difference between the suture tape and control groups in postoperative Tegner activity score, at 7.1 (95% confidence interval, 6.5-7.6) and 6.4 (95% confidence interval, 6.2-6.6), respectively (P = .026).ConclusionsACLR with hamstring autograft and independent suture tape reinforcement was performed safely with low rates of complications, graft failure, and reoperations with similar PROs, function, and return-to-sport rates when compared with hamstring autograft ACLR without suture tape reinforcement at a minimum 2-year follow-up.Level of evidenceLevel III, retrospective comparative study.
