Background: The indications for the addition of anterolateral soft tissue augmentation to anterior cruciate ligament (ACL) reconstruction and its effectiveness remain uncertain. Purpose: To determine if modified iliotibial band tenodesis (MITBT) can improve clinical outcomes and reduce the recurrence of ACL ruptures when added to ACL reconstruction in patients with a residual pivot shift. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: Patients with a primary ACL rupture satisfying the following inclusion criteria were enrolled: first ACL rupture, involved in pivoting sports, skeletally mature, no meniscal repair performed, and residual pivot shift relative to the contralateral uninjured knee immediately after ACL reconstruction. Patients were randomized to group A (no further surgery) or group B (MITBT added) and were followed up for 2 years. The patient-reported outcome (PRO) measures used were the International Knee Documentation Committee (IKDC) score, Knee injury and Osteoarthritis Outcome Score (KOOS) subscale of sport/recreation (Sport/Rec), KOOS subscale of quality of life (QoL), Lysholm knee score (LKS), Tegner activity scale (TAS), recurrent ACL ruptures, or need for further surgery in either knee. Analysis of variance was used to compare PROs; the Wilcoxon test was used for the TAS; and the chi-square test was used for recurrence of ACL ruptures, meniscal injuries, and contralateral ACL ruptures ( P < .05). Results: A total of 55 patients were randomized: 27 to group A (female:male ratio = 15:12; mean age, 22.3 ± 3.7 years) and 28 to group B (female:male ratio = 17:11; mean age, 21.8 ± 4.1 years). At 2-year follow-up, group A had a similar IKDC score (90.9 ± 10.7 vs 94.2 ± 11.2; respectively; P = .21), lower KOOS Sport/Rec score (91.5 ± 6.4 vs 95.3 ± 4.4, respectively; P = .02), similar KOOS QoL score (92.0 ± 4.8 vs 95.1 ± 4.3, respectively; P = .14), lower LKS score (92.5 ± 4.8 vs 96.8 ± 8.0, respectively; P = .004), lower TAS score (median, 7 [range, 7-9] vs 8 [range, 8-10], respectively; P = .03), higher rate of recurrence (14.8% vs 0.0%, respectively; P < .001), similar rate of meniscal tears (14.8% vs 3.6%, respectively; P = .14), and similar rate of contralateral ACL ruptures (3.7% vs 3.6%, respectively; P = .99) relative to group B. Conclusion: The augmentation of ACL reconstruction with MITBT reduced the risk of recurrent ACL ruptures in knees with a residual pivot shift after ACL reconstruction and improved KOOS Sport/Rec, LKS, and TAS scores.

AbstractIncreased laxity within the graft construct system can lead to graft failure after anterior cruciate ligament (ACL) reconstruction. Suboptimal cortical device positioning could lead to increased laxity within the system, which could influence the mechanics and function of the graft reconstruction. This study evaluates the benefit of intraoperative fluoroscopy to confirm device position on the femur during ACL reconstruction using cortical suspensory fixation. One hundred consecutive patients who underwent soft tissue ACL reconstruction using a suspensory cortical device for femoral fixation were retrospectively evaluated. Patients were split into two groups: Group A utilized anteromedial portal visualization and had intraoperative fluoroscopic imaging performed at the time of ACL graft fixation to confirm femoral device placement on the lateral femoral metaphyseal cortex. Group B utilized anteromedial portal visualization alone. Both groups had radiographic X-rays performed at the first postoperative visit to evaluate device location and all images were independently evaluated by three fellowship trained orthopaedic surgeons. Device position was classified as optimal if there was complete apposition of the entire device against the femoral cortex and suboptimal if it was > 2 mm off the cortex. Fisher's exact test, analysis of variance, and 95% confidence intervals were calculated to compare the groups for statistical significance. The results showed 0/60 (0%) patients in group A had suboptimal device position at postoperative follow-up, while 4/40 (10%) patients in group B had suboptimal device position (p = 0.013). There were no graft failures in group A and one graft failure in group B. There was a significant difference in cortical device position in patients who had intraoperative fluoroscopic imaging versus patients who had no intraoperative imaging. The use of confirmatory intraoperative imaging may be beneficial to confirm appropriate device location when using a femoral cortical suspensory fixation technique for ACL reconstruction.

Abstract Background We investigate the safety of the application of the Rigidfix cross-pin system via different tibial tunnels in the tibial fixation during anterior cruciate ligament (ACL) reconstruction. Methods Five adult fresh cadaver knees were fixed with the Rigidfix cross-pins in the tibial fixation site during ACL reconstruction. Two different tibial tunnel groups were established: in group A, the tunnel external aperture was placed at the 25° angle of coronal section; in group B, the tunnel external aperture was placed at the 45° angle of coronal section. The guide was placed at the plane 0.5 mm below articular facet through the tibial tunnel, with three rotation positions set at 0°, 30°, and 60° slopes. The incidences of iatrogenic injuries at tibial plateau cartilage (TPC), medial collateral ligament (MCL), and patellar tendon in three different slope angles were calculated in groups A and B and the results were analyzed by using chi square test. Results The iatrogenic injuries at MCL, TPC, and patellar tendon could occur after the Rigidfix cross-pin system was placed 5 mm below tibial plateau cartilage for ACL reconstruction. The incidences of TPC injury (χ2 = 5.662, P = 0.017) and MCL injury (P = 0.048, Fisher exact probability method) were significantly lower in group A than in group B. However, the incidence of patellar tendon injury showed no significant difference between these two groups (χ2 = 0.120, P = 0.729). Conclusions When the Rigidfix cross-pin system is used for ACL reconstruction at the tibial fixation site, the external aperture of tibial tunnel should not be placed at the excessively posterosuperior site, to avoid MCL and TPC injuries.

Introduction: The aim of this study is to evaluate advantages of close vs. open HTO of a group of patients who underwent a one-stage combined operation for chronic ACL rupture and early medial compartment arthritis. Material and Methods: We retrospective evaluated two series of patients operated on for anterior cruciate ligament (ACL) reconstruction combined with high tibial valgus osteotomy (HTO) for chronic anterior knee instability associated with medial tibio femoral osteoarthritis. Close HTO using rigid plate fixation and ACL reconstruction with bone patellar tendon bone graft was performed in Group A (7 patients). An open HTO using Puddu plate and ACL reconstruction with hamstring tendon graft was performed in Group B (9 patients). The mean age in Group A was 41 years old with an average varus of 8 degrees. Mean age in Group B was 42 years old and with 4 degrees of varus. Lysholm Score, HSS and Radiographs were performed. Results: Group A obtained a mean Lysholm score of 94, mean HSS of 91. Group B showed a mean Lysholm score of 83, mean HSS of 87. The mean follow-up was 5 years in both groups. In all cases osteotomies consolidated. Discussion: Technically we found that open HTO with hamstrings had several advantages such as lower risk of peroneal nerve injury, use of one incision, no problems as regards graft length, possibility of fixing the graft in the proximal tibia, maintenance of tibial slope and preservation of bone stock. The Open HTO need of osseous graft, may produce patella baja and the risk of nonunion is higher. This technique is indicated for relaxed medial collateral ligament. As regards the Close HTO there may be possibilities of a peroneal nerve injury, it may decrease the tibial slope, patellar ascent, loss of bone, the need to disrupt either the fibula or proximal tibio-fibular joint and may generate instability in the posterolateral corner and the screws could compromise the tunnels path. The advantages are provision of bone to bone contact with excellent union rates and the potential for full early weight-bearing. Conclusion: In spite of these issues, both procedures relieved pain and restored knee stability and the choice will depend on each particular case.

Background: Short-term and mid-term differences between hamstring and patellar tendon autografts for anterior cruciate ligament (ACL) reconstruction are well documented. Systematic reviews highlight the lack of long-term results between the two grafts. Hypothesis: Seventeen years after ACL reconstruction, no difference will be found in functional outcome, quality of life, and graft failure between patients with patellar tendon (PT) or semitendinosus and gracilis tendon (STG) autografts; however, a significant difference will be seen in the prevalence of osteoarthritis. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: Sixty-four patients were included in this prospective study (32 in each group). A single surgeon performed primary ACL reconstruction in alternating sequence. Forty-eight patients (24 in each group) were evaluated 17 years after ACL reconstruction: A clinical assessment was made based on the International Knee Documentation Committee (IKDC) form, instrumented laxity was measured with KT-1000 arthrometer, and radiography of the operated knee was conducted and assessed for degenerative disease. The Lysholm questionnaire and the Short Form–36 version 2 questionnaire were filled out by the patients. Results: At the 17-year follow-up, no statistically significant differences were seen with respect to graft failure (2 reruptures in the semitendinosus and gracilis tendon [STG] group [6.3%] and 3 reruptures in the PT group [9.4%]) and functional outcome. Increased instrumented laxity (>3 mm) measured with KT-1000 arthrometer was seen in significantly more patients in the STG group (8 in the STG group compared with 2 in the PT group; P = .03) with a mean side-to-side difference of 2.17 ± 1.86 mm in the STG group compared with 1.33 ± 1.93 mm in the PT group. A significant difference was found in frequency of knee osteoarthritis (OA)—100% in the PT group compared with 71% in the STG group ( P = .004). Patients in the PT group tended to have higher grade OA according to the IKDC grading system, with an average grade of 1.46 in the PT group compared with 1 in the STG group ( P = .055). The degenerative changes in the PT group were more common in the medial and patellofemoral compartments ( P = .003 and P = .04, respectively). Conclusion: Both autografts provided good to excellent subjective outcomes. No significant differences were noted in graft failure and clinical instability. However, significantly more patients in the STG group had increased instrumented anteroposterior translation measured with KT-1000 arthrometer, and there was a greater prevalence of knee OA at 17 years after surgery in the PT group.

Background: Increased tibial slope (TS) is believed to be a risk factor for anterior cruciate ligament (ACL) tears. Increased TS may also promote graft insufficiency after ACL reconstruction. Purpose: To delineate the relationship between TS and single as well as multiple graft insufficiencies after ACL reconstruction. Study Design: Cohort study; Level of evidence 3. Methods: We retrospectively identified 519 patients who had sustained ACL graft insufficiency after primary or revision ACL reconstruction (1 graft insufficiency, group A; 2 graft insufficiencies, group B; and ≥3 graft insufficiencies, group C). In addition, a subgroup analysis was conducted in 63 patients who received all surgical interventions by 2 specialized high-volume, single-center ACL surgeons. TS was measured by an observer with >10 years of training using lateral knee radiographs, and intrarater reliability was performed. Multiple logistic and univariate Cox regression was used to assess the contribution of covariates (TS, age, sex, and bilateral ACL injury) on repeated graft insufficiency and graft survival. Results: The study included 347 patients, 119 female and 228 male, who were 24 ± 9 years of age at their first surgery (group A, n = 260; group B, n = 62; group C, n = 25). Mean TS was 9.8°± 2.7° (range, 3°-18°). TS produced the highest adjusted odds ratio (1.73) of all covariates for repeated graft insufficiency. A significant correlation was found between TS and the number of graft insufficiencies ( r = 0.48; P < .0001). TS was significantly lower in group A (9.0°± 2.3°) compared with group B (12.1°± 2.5°; P < .0001) and group C (12.0°± 2.6°; P < .0001). A significant correlation was seen between the TS and age at index ACL tear ( r = −0.12; P = .02) as well as time to graft insufficiency ( r = −0.12; P = .02). A TS ≥12° had an odds ratio of 11.6 for repeated ACL graft insufficiency. Conclusion: The current results indicate that patients with a markedly increased TS were at risk of early and repeated graft insufficiency after ACL reconstruction. Because the TS is rarely accounted for in primary and revision ACLR, isolated soft tissue procedures only incompletely address recurrent graft insufficiency in this subset of patients.

Background: Heat necrosis due to motorized drilling during anterior cruciate ligament (ACL) reconstruction could be a factor in delayed healing at the bone–tendon graft interface. Hypothesis: The process of osteointegration could be enhanced using manual drilling. It reduces the invasiveness of mechanical-thermal stress normally caused by the traditional motorized drill bit. Study Design: Controlled laboratory study. Methods: ACL reconstruction using semitendinosus tendon autografts was performed in 28 skeletally mature female New Zealand white rabbits, which were randomly divided into 3 groups. In group A (n = 12), the tunnels were drilled using a motorized device; in group B (n = 12), the tunnels were drilled using a manual drill bit; and group C (n = 4) served as a control with sham surgical procedures. The healing process in the tunnels was assessed histologically at 2, 4, 8, and 12 weeks and graded according to the Tendon–Bone Tunnel Healing (TBTH) scoring system. In addition, another 25 rabbits were used for biomechanical testing. The structural properties of the femur–ACL graft–tibia complex, from animals sacrificed at 8 weeks postoperatively, were determined using uniaxial tests. Stiffness (N/mm) and ultimate load to failure (N) were determined from the resulting load-elongation curves. Results: The time course investigation showed that manual drilling (group B) had a higher TBTH score and improved mechanical behavior, reflecting better organized collagen fiber continuity at the bone–fibrous tissue interface, better integration between the graft and bone, and early mineralized chondrocyte-like tissue formation at all the time points analyzed with a maximum difference at 4 weeks (TBTH score: 5.4 [group A] vs 12.3 [group B]; P < .001). Stiffness (23.1 ± 8.2 vs 17.8 ± 6.3 N/mm, respectively) and ultimate load to failure (91.8 ± 60.4 vs 55.0 ± 18.0 N, respectively) were significantly enhanced in the specimens treated with manual drilling compared with motorized drilling ( P < .05 for both). Conclusion: The use of manual drilling during ACL reconstruction resulted in better tendon-to-bone healing during the crucial early weeks. Manual drilling was able to improve the biological and mechanical properties of bone–hamstring tendon graft healing and was able to restore postoperative graft function more quickly. Tunnel drilling results in bone loss and deficient tendon-bone healing, and heat necrosis after tunnel enlargement may cause mechanical stress, contributing to a delay in healing. Manual drilling preserved the bone stock inside the tunnel, reduced heat necrosis, and offered a better microenvironment for faster healing at the interface. Clinical Relevance: Based on study results, manual drilling could be used successfully in human ACL reconstruction, but further clinical studies are needed. A clinical alternative, called the original “all-inside” technique, has been developed for ACL reconstruction. In this technique, the femoral and tibial tunnels are manually drilled only halfway through the bone for graft fixation, reducing bone loss. Data from this study suggest that hamstring tendon–to–bone healing can be improved using a manual drilling technique to form femoral and tibial tunnels.

AbstractThere has been controversy about whether remnant tissue of anterior cruciate ligament (ACL) has to be preserved in ACL reconstruction. The purpose of the study was to compare clinical outcomes between groups of patients who underwent ACL reconstruction with bone-patellar tendon-bone (BPTB) autograft divided according to amount of ACL remnant and investigate effect of remnant preservation on outcomes of ACL reconstruction. A total of 185 patients who underwent ACL reconstruction with BPTB autograft were retrospectively reviewed. Patients were divided into four groups according to proportion of length of remnant tissue of injured ACL covering part of reconstructed ACL to total length of reconstructed ACL: group A included 83 patients with no remnant, group B consisted of 38 patients with remnant of < 1/3, group C consisted of 35 patients with remnant of 1/3 to2/3, and group D consisted of 29 patients with remnant of > 2/3. Primary outcome was International Knee Documentation Committee (IKDC) subjective score. Secondary outcomes were stability, range of motion, patient-reported outcomes determined by Lysholm knee scoring scale and Tegner activity scale, IKDC objective grade, and single hop for distance. Return to activity and near-return to activity were investigated. A minimum follow-up duration was 24 months. There was no statistically significant difference between four groups regarding postoperative anterior translation (p = 0.731), Lysholm knee score (p = 0.599), IKDC objective grade (p > 0.999), hop test (p = 0.878), and near-return to activity (p = 0.193). However, patients of group D had significantly better outcomes in IKDC subjective score (group A = 85.0 ± 5.9, group B = 84.9 ± 8.1, group C = 87.4 ± 6.4, group D = 89.2 ± 8.1, p = 0.017), Tegner activity scale (group A = 5.0 ± 1.1, group B = 5.2 ± 1.0, group C = 5.7 ± 1.3, group D = 5.9 ± 1.0, p = 0.001), and return to activity (group A = 25.3%, group B = 31.6%, group C = 45.7%, group D = 55.2%, p = 0.014). ACL reconstruction using BPTB autograft with remnant preservation did not provide better anterior stability compared with conventional ACL reconstruction. However, preservation of remnant of > 2/3 led to more improved activity-related clinical outcomes than no remnant preservation. In cases with substantial remnant tissue of injured ACL remaining, reconstruction of ACL while preserving as much remnant tissue as possible is recommended. This is a Level III, retrospective comparative therapeutic study.

Abstract Background For active patients with a tear of the anterior cruciate ligament (ACL) who would like to return to active level of sports, the current surgical gold standard is reconstruction of the ACL. Recently, there has been renewed interest in repairing the ACL in selected patients with a proximally torn ligament. Repair of the ligament has (potential) advantages over reconstruction of the ligament such as decreased surgical morbidity, faster return of range of motion, and potentially decreased awareness of the knee. Studies comparing both treatments in a prospective randomized method are currently lacking. Methods This study is a multicenter prospective block randomized controlled trial. A total of 74 patients with acute proximal isolated ACL tears will be assigned in a 1:1 allocation ratio to either (I) ACL repair using cortical button fixation and additional suture augmentation or (II) ACL reconstruction using an all-inside autologous hamstring graft technique. The primary objective is to assess if ACL repair is non-inferior to ACL reconstruction regarding the subjective International Knee Documentation Committee (IKDC) score at two-years postoperatively. The secondary objectives are to assess if ACL repair is non-inferior with regards to (I) other patient-reported outcomes measures (i.e. Knee Injury and Osteoarthritis Outcome Score, Lysholm score, Forgotten Joint Score, patient satisfaction and pain), (II) objective outcome measures (i.e. failure of repair or graft defined as rerupture or symptomatic instability, reoperation, contralateral injury, and stability using the objective IKDC score and Rollimeter/KT-2000), (III) return to sports assessed by Tegner activity score and the ACL-Return to Sports Index at two-year follow-up, and (IV) long-term osteoarthritis at 10-year follow-up. Discussion Over the last decade there has been a resurgence of interest in repair of proximally torn ACLs. Several cohort studies have shown encouraging short-term and mid-term results using these techniques, but prospective randomized studies are lacking. Therefore, this randomized controlled trial has been designed to assess whether ACL repair is at least equivalent to the current gold standard of ACL reconstruction in both subjective and objective outcome scores.

Background:Anterior cruciate ligament (ACL) reconstruction is a well-established surgical procedure for the correction of ACL ruptures. However, the incidence of instability following ACL reconstruction is substantial. Recent studies have led to greater insight into the anatomy and the radiographic characteristics of the native anterolateral ligament (ALL), along with its possible role in residual instability after ACL reconstruction.Method:The current paper describes a lateral extra-articular tenodesis to reconstruct the ALL during ACL procedures, using a short iliotibial band strip. The distal insertion of this strip is left intact on the anterolateral side of the proximal tibia, and the proximal part is fixed at the anatomic femoral insertion of the ALL.Results:Our technique avoids the sacrifice of one of the hamstring tendons for the ALL reconstruction. Additionally, there is no interference with the anatomical location or function of the LCL.Conclusion:Our technique offers a minimally invasive and nearly complete anatomical reconstruction of the ALL with minimal additional operative time.
