Influence of Bundle Diameter and Attachment Point on Kinematic Behavior in Double Bundle Anterior Cruciate Ligament Reconstruction Using Computational Model

A protocol to choose the graft diameter attachment point of each bundle has not yet been determined since they are usually dependent on a surgeon’s preference. Therefore, the influence of bundle diameters and attachment points on the kinematics of the knee joint needs to be quantitatively analyzed. A three-dimensional knee model was reconstructed with computed tomography images of a 26-year-old man. Based on the model, models of double bundle anterior cruciate ligament (ACL) reconstruction were developed. The anterior tibial translations for the anterior drawer test and the internal tibial rotation for the pivot shift test were investigated according to variation of bundle diameters and attachment points. For the model in this study, the knee kinematics after the double bundle ACL reconstruction were dependent on the attachment point and not much influenced by the bundle diameter although larger sized anterior-medial bundles provided increased stability in the knee joint. Therefore, in the clinical setting, the bundle attachment point needs to be considered prior to the bundle diameter, and the current selection method of graft diameters for both bundles appears justified.

Double Bundle Acl Reconstruction

Although the importance of the anterolateral stabilizing structures of the knee in the setting of anterior cruciate ligament (ACL) injuries has been recognized since many years, most of orthopedic surgeons do not take into consideration the anterolateral structures when performing an ACL reconstruction. Anatomic single or double bundle ACL reconstruction will improve knee stability, but a small subset of patients may experience some residual anteroposterior and rotational instability. For this reason, some researchers have turned again towards the anterolateral aspect of the knee and specifically the anterolateral ligament. The goal of this review is to summarize the existing knowledge regarding the anterolateral ligament of the knee, including anatomy, histology, biomechanics and imaging. In addition, the most common anterolateral reconstruction/tenodesis techniques are described together with their respective clinical outcomes.

Background: The effects of remnant tissue preservation on tunnel enlargement after anatomic double-bundle anterior cruciate ligament (ACL) reconstruction have not yet been established. Hypothesis: The preservation of ACL remnant tissue may significantly reduce the degree and incidence of tunnel enlargement after anatomic double-bundle ACL reconstruction, while the remnant-preserving procedure may not significantly increase the incidence of tunnel coalition after surgery. Study Design: Cohort study; Level of evidence, 2. Methods: A total of 79 patients underwent anatomic double-bundle ACL reconstruction. Based on the Crain classification of ACL remnant tissue, 40 patients underwent the remnant-preserving procedure (group P), and the remaining 39 patients underwent the remnant-resecting procedure (group R). There were no differences between the 2 groups concerning all background factors, including preoperative knee instability and intraoperative tunnel positions. All patients were examined using computed tomography and a standard physical examination at 2 weeks and 1 year after surgery. Results: During surgery, the femoral and tibial anteromedial (AM) tunnel sizes in both groups averaged 6.6 and 6.5 mm, respectively. The femoral and tibial posterolateral (PL) tunnel sizes in both groups averaged 6 and 6 mm, respectively. There were no differences in the intraoperative tunnel positions and tunnel sizes between groups. Concerning the femoral AM tunnel, the degree of tunnel enlargement in the oblique coronal and oblique axial views in group P was significantly less than that in group R ( P = .0068 and .0323, respectively). Regarding the femoral AM tunnel cross-sectional area, the degree and incidence of tunnel enlargement in group P were significantly less than those in group R ( P = .0086 and .0278, respectively). There were no significant differences in tunnel coalition between groups. In each group, there were no significant relationships between tunnel enlargement and each clinical outcome. Conclusion: Remnant preservation in anatomic double-bundle ACL reconstruction reduced enlargement of the femoral AM tunnel and did not increase the incidence of tunnel coalition. This is one of the advantages of remnant-preserving ACL reconstruction.

Double Bundle Acl Reconstruction

The anterior cruciate ligament (ACL) consists of 2 bundles: a slightly larger anteromedial bundle and a posterolateral bundle, named according to their relative tibial insertion sites. Both bundles are crucial to knee stability. Although it is more technically demanding, a double bundle ACL reconstruction restores the knee biomechanics better and provides more rotational stability than a single bundle ACL reconstruction. Intermediate and long-term clinical investigation including the measurement of rotational laxity and the evaluation of osteoarthritic change is needed to confirm biomechanical and short-term clinical outcomes.

Objective. A nonrandomized clinical study was performed to compare the clinical and radiological outcome between double-bundle and single-bundle anterior cruciate ligament (ACL) reconstructions with semitendinosus tendon in athletes. Material and methods. We examined 70 patients with unilateral anterior cruciate ligament injury. They were followed up for a mean of 24 months. Each group of 35 patients underwent either double- or singlebundle ACL reconstruction. The mean age of the patients was 24.7 years (range, 18–35 years). There were no differences between two groups regarding age at surgery, sex, follow-up period, period before surgery, combined meniscus injuries, athletic activity level, and International Knee Documentation Committee (IKDC) and Tegner scores. All patients followed the same postoperative program. They were evaluated using manual knee laxity tests, knee extension and flexion strength testing. General knee condition was evaluated by the IKDC and Tegner scores. Results. The results were excellent and good in 32 (91.4%) patients after double-bundle ACL reconstruction and in 30 (85.7%) patients after single-bundle ACL reconstruction, evaluating by IKDC system. However, statistical analysis showed no significant difference between the two groups regarding all IKDC-categorized data (P=0.87). The average scores of Tegner activity in double-bundle and single-bundle groups were 8.0 and 8.1, respectively. Conclusions. This trial showed no significant difference between the double and single-bundle ACL repairs.

Abstract Background In anterior cruciate ligament (ACL) reconstruction, the clinical outcome and level of post-operative pain are important factors. To date there have been no studies evaluating differences in post-operative pain between single bundle and double bundle ACL reconstruction with a hamstring graft. Hypothesis/purpose We hypothesized that post-operative pain in single bundle ACL reconstruction would be less than in double bundle ACL reconstruction. This study was to compare post-operative pain between patients undergoing single bundle versus double bundle ACL reconstruction. Study design Cohort study. Methods This was a retrospective study comparing post-operative pain scores between single bundle and double bundle ACL reconstruction. Each patient was given our standard regimen of oral diclofenac (25 mg/tab) three times per day and paracetamol (500 mg/tab) six times per day for 1 day post-operatively. If the patient complained of moderate to severe pain (pain numeric rating scale (PNRS) > 3), 3 mg of morphine was injected intravenously every 3 h for 24 h and 1 mg of morphine as a rescue medication every 1 h for 24 h. PNRS and morphine consumption were recorded at 4-h intervals for 24 h. Results 209 patients were included in this study of whom 102 and 107 patients received single bundle and double bundle ACL reconstruction, respectively. The average post-operative pain scores of the single bundle group were lower at all time points. Linear mixed effect regression analyses showed that the single bungle group had lower post-operative pain than the double bundle group after adjusting for confounders (beta = − 0.45; 95% CI = − 0.838, − 0.062) but there was no statistically significant difference between numbers of bundle ACL reconstruction with regard to morphine consumption. Conclusion Single bundle ACL reconstruction had significantly lower post-operative pain scores than double bundle ACL reconstruction. Clinical relevance Double bundle ACL reconstruction results in higher post-operative pain, which may slow the start of rehabilitation and reduce patient satisfaction. In middle-aged adult patients with low-demand activities, we suggest performing a single bundle ACL reconstruction.

Background: Remnant tissue preservation may be important in improving graft healing after anterior cruciate ligament (ACL) reconstruction, but it has yet to be established whether remnant tissue preservation improves the control of pivot-shift laxity. Hypothesis: The amount of ACL graft coverage with preserved remnant tissue improves the control of pivot-shift laxity, as qualitatively determined with an electromagnetic device. Study Design: Cohort study; Level of evidence, 3. Methods: The 3-dimensional kinematics were evaluated intraoperatively using an electromagnetic sensor system in 38 patients at the time of anatomic double-bundle ACL reconstruction with remnant tissue preservation and again at a minimum of 12 months postoperatively. The magnitude of the peak coupled anterior tibial translation (pCAT) and the maximal acceleration of posterior translation (APT) during the pivot-shift test were evaluated. The degree of graft coverage by remnant tissue was determined arthroscopically at the end of surgery, which was evaluated quantitatively using a scoring system (0-9 points). The relationship between the values during the pivot-shift test and preoperative and intraoperative factors were assessed. Results: The mean (±SD) side-to-side difference of the pCAT (ΔpCAT) was significantly ( P < .0001) improved from 14.0 ± 5.0 mm to 2.6 ± 1.1 mm. Also, the mean side-to-side difference of the APT (ΔAPT) was significantly ( P < .0001) improved from 525.6 ± 99.7 mm/s2 to 32.9 ± 23.6 mm/s2. The mean initial graft coverage score was 5.3 ± 2.6. The correlation analysis demonstrated that the degree of initial graft coverage was significantly correlated with the ΔpCAT ( r = −0.517, P = .0007) and ΔAPT ( r = −0.532, P = .0005). The status of the reconstructed graft at second-look arthroscopic surgery showed no significant correlations with the degree of initial graft coverage or the results of the pivot-shift test. Conclusion: The present study demonstrated that the preservation of ACL remnant tissue in anatomic double-bundle ACL reconstruction appears to improve the control of pivot-shift laxity at a minimum of 12 months postoperatively, as measured by an electromagnetic device. This improvement was significantly affected by the degree of intraoperative graft coverage with preserved remnant tissue.

AbstractKnee joint infections constitute a rare but devastating complication after anterior cruciate ligament (ACL) reconstruction. We hypothesized that effective infection therapy and graft preservation is possible following a standard treatment protocol. We retrospectively analyzed all patients admitted to our center with suspected infection of the knee after ACL reconstruction between 2010 and 2012. Following a standardized protocol, blood samples were drawn and synovial fluid was analyzed. Furthermore, the protocol consisted of arthroscopic lavages and debridements of the anterior and posterior joint compartments over three incisions, and targeted antibiotic therapy over a period of 6 weeks. Surgeries were repeated every 2 days until clinical signs of infections resolved, but at least two times. Mean observation period was 10 months. Forty-one patients aged 31 ( ± 9.9) years and admitted 14 ( ± 7.5) days after ACL reconstruction were included. Pathogens were found in 34 patients and coagulase-negative staphylococci were isolated most commonly (31 isolates in 28 patients). Quinolones were the most commonly used antibiotic agents. Mean number of operations was 3.8 ( ± 1.4). Following the standard protocol, primary successful infection treatment with graft preservation was possible in 37 of the included 41 patients. Graft preservation was achieved in 100% of the included patients with Gaechter stage 1 and 2 infections. Knee joint infection after ACL reconstruction was successfully treated following a standardized protocol, and graft preservation was reliably achieved especially in cases with infections at an early stage.
