Background. Research aim was to analyze the quadriceps muscle strength recovery after anterior cruciate ligament reconstruction using electrical stimulation and physical therapy. Methods. There were two randomly selected groups, with eight people in each group. The selection criteria were that the subjects had to have anterior cruciate ligament operation six weeks prior and were very active physically. One group was for research (study group), the other one for reference (control group). The study group had electrical stimulation combined with physical therapy exercises two times a week, for 45 minutes. The control group had exercises to strengthen the quadriceps muscle also two times a week, for 45 minutes. Both groups were tested before and after the research. The things evaluated during the test were – visual pain scale (VAS) scores, quadriceps muscle strength during extension and flexion using (R. Lovett) scoring system and goniometry showing degrees of extension and flexion. Results. Comparing both study and control groups, there was statistically signifcant improvement (p < 0.05), however the study group recovered faster and had statistically greater benefts. Conclusions. After 6 weeks of physiotherapy, the range of motion, quadriceps muscle strength increased and pain decreased in the operated leg. 1. After 6 weeks of physiotherapy and electrical stimulation, the range of motion, quadriceps muscle strength increased and pain decreased in the operated leg. 2. After 6 weeks of physiotherapy and electrical stimulation, the range of motion, quadriceps muscle strength, pain in the operated leg changed more in the study group than in subjects who received only physical therapy.Keywords: anterior cruciate ligament, electrical stimulation, quadriceps muscle, ligament reconstruction, muscle strength.

Context: To treat anterior cruciate ligament (ACL) injury, ACL reconstruction (ACLR) surgery is currently a standard of the care. However, effect of graft type including bone–patellar tendon–bone (BTB), hamstring tendon, or iliotibial band (ITB) on thigh size, knee range of motion (ROM), and muscle strength are understudied. Objective: To compare postoperative thigh circumference, knee ROM, and hip and thigh muscle strength in adolescent males who underwent ACLR, based on the 3 different autograft types: BTB, hamstring (HS), and ITB. Setting: Biomechanical laboratory. Participants: Male ACLR patients who are younger than 22 years of age (total N = 164). Intervention: At 6- to 9-month postoperative visits, thigh circumference, knee ROM, and hip and thigh muscle strength were measured. Main Outcome Measures: Deficits of each variable between the uninvolved and ACLR limb were compared for pediatric and adolescent ACLR males in the BTB, HS, and ITB cohorts. Baseline characteristics, including physical demographics and meniscus tear status, were compared, and differences identified were treated as covariates and incorporated in analysis of covariance. Results: Data were from 164 adolescent male ACLR patients [mean age 15.7 (1.2) years]. There were no statistical differences in thigh circumference, knee ROM, hip abductor, and hip-extensor strength among the 3 autografts. However, patients with BTB demonstrated 12.2% deficits in quadriceps strength compared with 0.5% surplus in HS patients (P = .002) and 1.2% deficits in ITB patients (P = .03). Patients with HS showed 31.7% deficits in hamstring strength compared with 5.4% deficits in BTB (P = .001) and 7.7% deficits in ITB (P = .001) groups at 6- to 9-month postoperative visits. Conclusion: Adolescent male ACLR patients with BTB and HS autografts demonstrated significant deficits in quadriceps and hamstring strength, respectively, at 6 to 9 months postoperatively. Minimal lower-extremity strength deficits were demonstrated in pediatric male ACLR patients undergoing ITB harvest.

Context: Anterior cruciate ligament (ACL) injuries are a common and devastating injury in women’s soccer. Several risk factors for ACL injury have been identified, but have not yet been examined as potentially dynamic risk factors, which may change throughout a collegiate soccer season. Design: Prospective cohort study. Methods: Nine common clinical screening assessments for ACL injury risk, consisting of range of motion, movement quality, and power, were assessed in 29 Division I collegiate women’s soccer players. Preseason and midseason values were compared for significant differences. Change scores for each risk factor were also correlated with cumulative training loads during the first 10 weeks of a competitive soccer season. Results: Hip external rotation range of motion and power had statistically significant and meaningful differences at midseason compared with preseason, indicating they are dynamic risk factors. There were no significant associations between the observed risk factor changes and cumulative training load. Conclusions: Hip external rotation range of motion and power are dynamic risk factors for ACL injury in women’s collegiate soccer athletes. Serial screening of these risk factors may elucidate stronger associations with injury risk and improve prognostic accuracy of screening tools.

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

Abstract Anterior Cruciate Ligament (ACL) tear is one of the most common knee injuries. The ACL reconstruction surgery aims to restore healthy knee function by replacing the injured ligament with a graft. Proper selection of the optimal surgery parameters is a complex task. To this end, we developed an automated modeling framework that accepts subject-specific geometries and produces finite element knee models incorporating different surgical techniques. Initially, we developed a reference model of the intact knee, validated with data provided by the OpenKnee project. This helped us evaluate the effectiveness of estimating ligament stiffness directly from MRI. Next, we performed a plethora of “what-if” simulations, comparing responses with the reference model. We found that a) increasing graft pretension and radius reduces relative knee displacement, b) the correlation of graft radius and tension should not be neglected, c) graft fixation angle of 20 degrees can reduce knee laxity, and d) single-versus double-bundle techniques demonstrate comparable performance in restraining knee translation. In most cases, these findings confirm reported values from comparative clinical studies. The numerical models are made publicly available, allowing for experimental reuse and lowering the barriers for meta-studies. The modeling approach proposed here can complement orthopedic surgeons in their decision-making.
