Bone Grafting Technique in Revision ACL Reconstruction: Coring Reamer and Dowel Trick

ABSTRACT: One- or two-staged bone grafting is sometimes required for tunnel malposition and/or tunnel widening in revision anterior cruciate ligament (ACL) reconstruction. The aim of this procedure is to restore the correct position of the ACL graft in the revision setting to provide a stable and functional ACL, thereby reproducing normal knee kinematics. We present a technique that allows for a cost-effective, convenient tunnel grafting of a femoral head allograft bone dowel into both femoral and tibial defects in revision ACL reconstruction. Technique Video Video Use of the cannulated Coring Reamer System (Arthex, Naples, FL) to perform the harvest. A 2.4-mm guide pin is placed through the femoral head and neck allograft, parallel to the neck axis. A coring reamer and plunger should be used to harvest a core diameter identical to that of the reamed tunnels. The coring reamer’s centralizing plunger with its guide pin should be left in its already cannulated position through the harvested core. This entire construct will be used to easily graft the associated tunnel. The allograft dowel is then marked 5 mm greater than the corresponding depth of the femoral socket, in accordance with the prior reaming depth. This step allows for compression of the cancellous portion of the bone dowel into the tunnel. At this mark, a narrow rongeur is used to weaken the bone dowel circumferentially, leaving a small bone bridge. The entire construct is then introduced via the tibial tunnel or anteromedial portal, depending on the trajectory previously used to ream the femoral tunnel. The plunger-pin-dowel construct is then advanced into the femoral tunnel by gently tapping a pin puller that is solidly gripping the guide pin. Once the femoral dowel is fully seated and flush with the opening of the femoral defect, the dowel’s bone bridge is then broken at the previously weakened site with the use of a probe. The remaining dowel is removed from the knee using a powered wire driver. (It will come out easily with the plunger-pin construct en bloc.) The remaining dowel is then repositioned into the tibial tunnel and tapped into position as desired. Using the remainder of the first dowel, a second one can be harvested easily if the tibial tunnel is not completely grafted.

Project description:BackgroundIndependent transtibial pullout repair is a common surgical technique for repairing lateral meniscus posterior root tears (LMPRTs). The shared anterior cruciate ligament (ACL) bone tunnel technique is an alternative technique for LMPRT repair combined with ACL reconstruction (ACLR) to avoid the establishment of additional bone tunnels.PurposeTo compare the clinical outcomes of the shared ACL bone tunnel versus the independent transtibial pullout techniques for LMPRT repair combined with ACLR.Study designCohort study; Level of evidence, 3.MethodsBetween March 2014 and February 2018, a total of 48 patients were diagnosed with ACL injury with concomitant LMPRT; 22 patients underwent independent transtibial pullout repair (group T), and 26 patients underwent the shared ACL bone tunnel technique (group S). At a follow-up of >2 years, we compared knee functional recovery using the Lysholm, Tegner, and International Knee Documentation Committee scores and the pivot-shift test. Lateral meniscal extrusion, and cartilage degeneration on magnetic resonance imaging (MRI) scans were also compared. The healing status of the lateral meniscus posterior root was compared using second-look arthroscopy and MRI.ResultsThe duration of surgery was significantly shorter in group S compared with group T (98.3 ± 11.1 vs 127.9 ± 17.5 min; P = .001). At final follow-up, there were no significant differences between the 2 groups in knee functional scores, pivot shift, or grade of cartilage degeneration. Lateral meniscal extrusion was decreased in group S compared with group T (2.41 ± 0.61 vs 1.59 ± 1.35 mm; P = .014). Second-look arthroscopy revealed stable healing in 16 of 18 patients (88.9%) in group S and 10 of 15 patients (66.7%) in group T (P = .38).ConclusionBoth the shared ACL bone tunnel and the independent transtibial pullout techniques led to satisfactory clinical outcomes. The shared ACL bone tunnel technique is the simpler of the 2 procedures for combined LMPRT repair with ACLR.

Project description:BackgroundGraft failure after anterior cruciate ligament reconstruction (ACLR) is a debilitating complication often requiring revision surgery. It is widely agreed upon that functional knee outcomes after revision ACLR (r-ACLR) are inferior compared with those after primary reconstruction. However, data are scarce on outcomes after multiple-revision ACLR (mr-ACLR).PurposeTo compare patient-reported knee function in terms of Knee injury and Osteoarthritis Outcome Score (KOOS) preoperatively and 1-year postoperatively after primary ACLR, r-ACLR, and mr-ACLR and evaluate the pre- to postoperative improvement in KOOS scores for each procedure.Study designCohort study; Level of evidence, 3.MethodsPatients from the Swedish National Knee Ligament Registry who underwent their index ACLR between 2005 and 2020 with a minimum age of 15 years at the time of surgery were included in this study. All patients had pre- and postoperative KOOS data. The 1-year postoperative KOOS and the pre- to postoperative changes in KOOS were assessed between patients who underwent primary ACLR and those who underwent subsequent r-ACLR and mr-ACLR.ResultsOf 20,542 included patients, 19,769 (96.2%) underwent primary ACLR, 760 (3.7%) underwent r-ACLR, and 13 (0.06%) underwent mr-ACLR. Patients who underwent r-ACLR had significantly smaller pre- to postoperative changes on all KOOS subscales compared with patients undergoing primary ACLR (P < .0001 for all). Furthermore, patients in the mr-ACLR group had significantly smaller changes in the KOOS-Pain subscale compared with patients in the r-ACLR group (-9 ± 23.3 vs 2.5 ± 18; P = .024).ConclusionThe study results indicated that while improvement is seen after primary ACLR, r-ACLR, and mr-ACLR, the greatest improvement in functional outcomes is observed after primary ACLR. Patients who underwent at least 1 r-ACLR, specifically mr-ACLR, had lower postoperative outcome scores, indicating that primary ACLR may provide the best chance for recovery after ACL injury.
