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.

The purpose of our study was to analyze the graft contact stress at the tunnel after transtibial single-bundle (SB) and transportal double-bundle (DB) anterior cruciate ligament (ACL) reconstruction. After transtibial SB (20 cases) and transportal DB (29 cases) ACL reconstruction, the three-dimensional image of each patient made by postoperative computed tomography was adjusted to the validation model of a normal knee and simulated SB and DB ACL reconstructions were created based on the average tunnel position and direction of each group. We also measured graft and contact stresses at the tunnel after a 134 N anterior load from 0° to 90° flexion. The graft and contact stresses became the greatest at 30° and 0° flexion, respectively. The total graft and contact stresses after DB ACL reconstruction were greater than those after SB ACL reconstruction from 0° to 30° and 0° to 90° knee flexion, respectively. However, the graft and contact stresses of each graft after DB ACL reconstruction were less than those after SB ACL reconstruction. In conclusion, the total graft and total contact stresses after DB ACL reconstruction are higher than those after SB ACL reconstruction from 0° to 30° and 0° to 90° knee flexion, respectively. However, the stresses of each graft after DB ACL reconstruction are about half of those after SB ACL reconstruction.

AbstractSingle-bundle (SB) anterior cruciate ligament (ACL) reconstruction is increasingly used in a large number of patients and it allows obtaining very good clinical and subjective results; however, functional tests show a persistent rotational instability. Biomechanical studies seem to indicate that double-bundle (DB) ACL reconstruction allows to obtain increased anterior and rotational stability compared with SB. The aim of this prospective randomized controlled study was to compare the clinical outcome and the possible osteoarthritic evolution of patients treated either with a SB (freehand transtibial femoral tunnel) or with a DB technique (outside-in for posterolateral femoral tunnel/inside-out for anteromedial femoral tunnel) at a final follow-up of 6 years. A total of 60 patients with complete ACL rupture (age, 16–40 years) were prospectively randomized to SB (n = 30) or DB (n = 30) groups. Patients were evaluated preoperatively and after surgery at 6 months, 1, 3, and 6 years with Lysholm score, International Knee Documentation Committee (IKDC) form, and KT-2000 (Medmetric Corp). The degree of osteoarthritis (OA) based on the Kellgren–Lawrence grade was also assessed. No significant differences in background factors between the two groups were observed. Homogeneity was also found in term of preoperative Lysholm score, IKDC, and KT-2000 between SB and DB groups. After 6 months from surgery, both groups showed significant improvements for Lysholm, IKDC, and KT-2000 score with respect to preoperative observations (p < 0.001); however, no significant differences have been observed in term of postoperative values between SB and DB groups at each time point (6-year evaluation: Lysholm score 98.14 ± 10.03 and 97.22 ± 12.82; IKDC normal + nearly normal 95 and 100%; KT-2000 1.68 ± 1.26 and 1.03 ± 1.92 for SB and DB, respectively; all p > 0.05). At the final follow-up, three patients (11.11%) in the DB group and two patients (7.69%) in the SB group presented signs of OA progression. Our study did not reveal any advantages in using DB ACL reconstruction in mid- to long-term follow-up in term of clinical outcome and knee stability, as well as in term of OA progression.

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.

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.
