Purpose of the study: to provide a scientific basis for the recommendations on clinical use of lateral extraarticular tenodesis (LEAT) from semitendinosus tendon (ST) graft as an additional element for knee stability in anterior cruciate ligament (ACL) anatomical anterograde reconstruction. Patients and methods. Treatment results were evaluated for 162 patients (mean age 27.2±2.8) with marked rotational joint instability (Pivot shift test 3+) after arthroscopic anterior cruciate ligament reconstruction (ACL-R). In 44 (27.2%) observations ACL-R was supplemented by LEAT from ST (group 1), in 118 (72.8%) the isolated anatomical anterograde plasty of ACL was performed (group 2). Lysholm Knee Scoring Scale, KOOS and 2000 IKDC were used for the assessment of the results. Results. Follow up period made up at least 2 years. Statistically significant differences between the groups were recorded in 21 months after intervention and later. In 43 (97.7%) patients from the 1group and 111 (94.1%) patients from the 2group excellent and good results (A and B by 2000 IKDC) were achieved. In 1 (2.3%) and 7 (5.9%) patients the results were assessed as satisfactory (C by 2000 IKDC), respectively. No statistically significant differences between the groups were recorded by Lysholm Knee Scoring Scale and 2000 IKDC (p>0.05). The average scores by KOOS that indicated the presence of pathological processes in the knee joint and characterized patient’s sport activity were statistically (p

AbstractTo compare the clinical results and ligamentization of anterior cruciate ligament reconstruction (ACLR) between skeletally immature and mature patients. Two-hundred-and-two patients who underwent primary ACLR were evaluated retrospectively. The clinical outcomes were compared between skeletally immature (immature group 1, n = 27) and mature (control group 1, n = 175) groups. Graft ligamentization of the reconstructed anterior cruciate ligament (ACL) using magnetic resonance imaging (MRI) signal intensity at 6 months postoperatively was compared between immature group 2 (n = 16), which included participants from immature group 1, and control group 2 (n = 32), created by recruiting data-matched controls from control group 1. Immature group 1 had significantly higher revision (14.8%) and pivot shift test positive (22.2%) rates than control group 1 (2.9% and 4.0%, respectively) (P = 0.020 and 0.003, respectively). The signal intensity in immature group 2 were significantly higher at the mid-substance and distal site of the reconstructed ACL than those in control group 2 (P = 0.003 and 0.034, respectively). Skeletally immature patients had higher graft revision and residual rotational laxity rates. Reconstructed ACL in skeletally immature patients showed higher signal intensity on MRI at 6 months postoperatively.

Theobjectivewas to compare the effectiveness of isolated anatomical antegrade reconstruction of the anterior cruciate ligament (ACL) with bonetendon-bone autograft (BTB autograft) and in combination with lateral extra-articular tenodesis (LEAT) graft from the iliotibial tract (ITT).Material and methods. We analyzed 187 arthroscopic ACL reconstructions in patients with a Pivot shift test – 3+ degree. We performed an isolated ACL-R in 118 (63.1 %) patients in group 1 and added the LEAT from ITB to it in group 2.Results. According to IKDC-2000: 176 (94.1 %) patients were included in categories A and B, 11 (5.9 %) – in C. Significant differences in these groups appeared 15 months after the operation. According to KOSS: in group 2, the anterior and rotational knee stability, as well as the level of sports activity were higher, and pathological symptoms were less common.Conclusion. LEAT from ITB increases stability and functionality of the knee joint in patients with anatomical antegrade ACL reconstructions with BTB-autograft for terms over 15 months after the operation, and is an economically procedure.

This article aims to evaluate factors associated with chondral and meniscal lesions in primary and revision anterior cruciate ligament (ACL) reconstructions. ACL reconstructions from 2001 to 2008 at a single institution were retrospectively analyzed. Logistic regression was used to estimate the association between chondral and meniscal injuries and age, gender, tear chronicity, additional ligamentous injuries, sport type, and participation level. Of the 3,040 ACL reconstructions analyzed, 90.4% were primary reconstructions and 9.6% were revisions. Meniscal injuries were significantly lower in the revision group (44.0 vs. 51.9%; p = 0.01), while chondral injuries were significantly higher in the revision group (39.9 vs. 24.0%; p < 0.0001). Inspection of the small subgroup (n = 85) receiving both primary and revision ACL surgery at our center indicated that meniscal injuries at revision were evenly split between menisci with and without previous repairs, whereas the vast majority of Grade III and IV chondral lesions were new. More patients presented for surgery later in the revision group than in the primary group (56.5 vs. 35.3%; p < 0.0001). Male gender, primary reconstruction, and short interval (less than 2 weeks) between injury and surgery were associated with increased likelihood of meniscus tear. Age (greater than 22 years) and long interval (greater than 6 weeks) between injury to surgery and higher sport activity level were associated with chondral lesions. Revision ACL reconstructions are associated with a higher proportion of chondral lesions and a lower proportion of meniscal tears. Early primary and revision ACL construction is recommended to reduce the probability of chondral lesions.

Objectives: We investigated the effects anatomic or nonanatomic femoral tunnel positions and tunnel fixation methods obtained using two different surgery methods on tunnel widening and clinical results in anterior cruciate ligament (ACL) reconstructions. Methods: Patients with isolated anterior cruciate ligament rupture are included to study who don’t have intra-and extra-articular additional pathology of the knee, without previously a history of operations of both knees. 2 groups were created. Group 1 Aperfix implant were used which can be able to perform non anatomical femoral tunnel and intra tunnel fixation with transtibial technique. In Group 2 Endobutton CL implant were used which can make fixation from outside the cortex with anatomic femoral tunnel in use of anteromedial portal techniques. 27 patients (average age 29,33, range 18 to 55 years) in group 1 and 27 patients (average age 27,51, range 16 to 45 years) in group 2 totally 54 patients were performed surgery. All patients were assessed using the IKDC (International knee documentation committee), Tegner Activity Scala and Lysholm II Functional Scores. Muscle strength measurements in both groups compared to intact knee was measured with an isokinetic dynamometer Biodex System 3 Pro. The location of the femoral tunnel aperture and tunnel widening were imaged with 3D reconstructive computed tomography. All measurements were performed using the same software application by the same radiologist. Results: The two groups were similar with respect to age and sex distribution, operated side, the size of the tunnel created, and follow-up period (p>0.05). After surgery in both groups, the clinical scores showed significant improvement compared to preoperative (p=0,0001). However, postoperative clinical outcomes in the two groups did not show a difference significantly (p>0,005). Isokinetic muscle strength study showed significant differences between the two groups (p=0,0001). Location of femoral tunnel aperture on the medial wall of the lateral femoral condyle showed a significant differences in the two groups (p=0,0001). The expansion of proximal and distal femoral tunnel in two groups showed significant differences (p=0,0001). There was relationship between distal femoral tunnel widening and location of femoral tunnel aperture. Conclusion: Although there is no statistically significant difference between the two groups clinically, difference noticed in terms of isokinetic muscle strength may be due to differences in the degree of shift as a result of multiple loading depending on the biomechanical properties of materials. We thought that the difference seen in the widening of tunnel in the proximal or distal may be due to, the technique of graft fixation, the distance between the fixation point and the joint, and to the location of the femoral tunnel aperture on medial wall of lateral condyle from anatomical or non anatomical region. There is no golden standard in neither surgical technique nor material of fixation. Proper theoretical knowledge and extensive clinical experience are important in the light of an accurate surgical technique applied. We thought that information we have reached in our study should be supported by biomechanical studies

Background: Septic arthritis (SA) of the knee after anterior cruciate ligament reconstruction (ACLR) is a rare but potentially devastating condition. In certain cases, graft removal becomes necessary. Purpose: To evaluate clinical, subjective, and radiologic outcomes of patients with SA after ACLR and assess whether graft retention has superior clinical results as compared with graft removal. Study Design: Cohort study; Level of evidence, 3. Methods: All patients who were at least 12 months out from arthroscopic treatment of SA after isolated ACLR at our institution were eligible for inclusion. Patients were categorized into 2 groups: group 1, patients with initial graft retention; group 2, patients with initial graft removal. Group 2 was subdivided into 2 groups: group 2a, patients with graft reimplantation; group 2b, patients without graft reimplantation. Objective and subjective assessments were obtained at follow-up, including the International Knee Documentation Committee (IKDC) knee examination form, KT-1000 arthrometer measurements, WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) score, Lysholm score, and IKDC subjective evaluation. Radiologic assessment was performed with pre- and postoperative magnetic resonance imaging. Results: Of the 41 patients included, 33 (81%) were available for follow-up at a mean ± SD 54.7 ± 24.4 months at an age of 28.4 ± 9.3 years. When compared with patients from group 2 (n = 12), patients from group 1 (n = 21) obtained significantly better results on the objective IKDC score (normal or nearly normal: group 1, 66.6%; group 2, 36.4%; P = .047) and KT-1000 measurements (group 1, 1.3 ± 1.0 mm; group 2, 2.9 ± 1.5 mm; P = .005). Group 1 also scored better than group 2 on the Lysholm ( P = .007), IKDC subjective ( P = .011), and WOMAC ( P = .069) measures. Between groups 2a (n = 4) and 2b (n = 8), no significant differences in outcomes could be detected ( P values, .307-.705), although patients with anterior cruciate ligament graft reimplantation showed a clear tendency toward better results in objective and not subjective parameters. Magnetic resonance imaging evaluation showed higher rates of cartilage damage and meniscal tears among patients with graft resection versus graft retention. Conclusion: Patients with graft retention showed superior postoperative results when compared with patients who underwent initial graft resection, although subanalysis showed comparable outcomes between graft retention and reimplantation. Thus, while graft-retaining protocols should have the highest priority in the treatment of SA after ACLR, graft reimplantation should be performed in cases where graft resection becomes necessary, to avoid future cartilage and meniscal lesions. Finally, further studies with larger numbers of patients are needed to gain a better understanding of the outcomes of patients with SA after ACLR.
