Abstract
Background: One of the most common orthopedic complaints is direct or indirect trauma to the knee with torn anterior cruciate ligament (ACL). Reconstruction of the torn ACL is emphatically offered in active individuals as by this operation, we prevent osteoarthritis, knee instability and injury to the meniscus. There are numerous methods for graft fixation in the femoral tunnel in ACL reconstruction. If the graft proves to be stable after the operation, patients would not complain of giving way knee joints. In this clinical trial, we compared transfemoral pinning with endobutton fixation of hamstring graft in arthroscopic ACL reconstruction by examining knee stability and use of other relevant functional tests.
Methods: Fourteen Patients who had undergone arthroscopic ACL reconstruction in Shariati Hospital during the years 2008-2009 and were being followed up were evaluated at least 15 months post-operatively by physical examination and the use of an
arthrometer made by the Faculty of Mechanics of Sharif Technical University.
Results: The results showed that two out of seven patients in which their ACL had been reconstructed by hamstring graft fixation by endobutton technique, and in one out of seven patients who had undergone ACL reconstruction by hamstring graft fixation through transfemoral pinning, Lachmann test (in 25 position) was greater than 5 mm but there were not any complaints of giving way knee joints.
Conclusion: The clinical results of ACL reconstruction by transfemoral pinning technique seems to be superior to the reconstruction by endobutton technique.

Abstract
Background: Anterior cruciate ligament (ACL) reconstruction is a first choice treatment for ACL-deficient knees, and arthroscopic single-bundle reconstruction has been widely accepted around the world in this regard. Although, such single-bundle reconstructions result in sufficient knee stability in most cases, but some patients have not been satisfied with postsurgical results in both short-term and long term clinical studies. One of the reasons for these unsatisfactory results could be related to the fact that normal function of the native ACL has not been restored by the traditional ACL reconstruction which uses only a single-bundle graft. The natural ACL consists of a 3-dimensional structure with multibundle fascicles, which can be anatomically divided into 2 main bundles, the anteromedial (AM) and the posterolateral (PL) bundles named for the orientation of their tibial insertions. The purpose of the present study was to compare double-bundle and single-bundle ACL reconstruction.
Methods: Twenty-two patients with anterior cruciate ligament tear who were candidates for ACL reconstruction were enrolled in the study undertaken in Shariati Hospital from 2009 to 2010. Fourteen patients underwent single-bundle and 8 patients double-bundle ACL reconstruction. The patients were evaluated by arthrometer and physical examination in postoperation follow up visit at least 9 months after the operations.
Results: Four out of 14 patients with single-bundle reconstruction had knee joint translation greater than 5 mm but nobody had knee translation more than 5 mm in the double-bundle reconstruction group.
Conclusion: Double-bundle ACL reconstruction seems to be more stable than single-bundle ACL reconstruction.

Abstract
Background: The goal of this study was to evaluate, functional capacity of the knee in flexion and internal rotation after hamstring ligament harvest for Anterior Cruciate Ligament (ACL) reconstruction.
Methods: Fifty patients (male and 18-45 years old) with isolated ACL injury, randomly allocated in two equal groups (in one group, ACL reconstruction was performed with Tibialis Posterior allograft and in another group with quadruple hamstring ligament auto graft) and before and 6 months after surgery in both groups isokinetic flexion strength and isometric internal rotation strength of knee evaluated with Biodex System 4 dynamometer and rotational torque recorder, in order. Isokinetic flexion strength evaluated in sitting and prone position the later position was performed for deep flexion strength evaluation. Also subjective and objective assessment of all patients pre operatively and 6 months post operatively was documented with International Knee Documentation Committee (IKDC) questionnaire. In this study for first time, rotational torque strength of knee was recorded with new design measure, from isometric aspect and not isokinetic.
Results: Although significant improvements in IKDC scores, flexion and internal rotation capacity of the knee were observed in both groups, post operatively in respect to pre operatively there was no significant difference between 2 groups. (P<0.05 or more than 95% confidence Interval of the difference)
Conclusion: This study demonstrates that ACL reconstruction surgery, improves knee performance in flexion and internal rotation, regardless of hamstring tendon harvesting. Considering potential complications of allograft (for example: transfer of harmful diseases from donor to recipient), it is logical to use hamstring auto graft ligament for ACL reconstruction surgery. Because result of this study is not longstanding follow up and limited to male sex, for more worthfull conclusion, we suggest future study in both sex and with long duration of follow up.

Abstract
Background: The amount of anterior tibial translation during rehabilitation exercises is a key factor in organizing exercise regimen after anterior cruciate ligament injury. Excessive anterior tibial translation could increase the magnitude of tension imposed on injured and reconstructed anterior cruciate ligament knees. Forward lunge and open-kinetic knee extension exercises are commonly used in anterior cruciate ligament rehabilitation. However, there is insufficient data about the amount of anterior tibial translation in the eccentric and concentric phases of these exercises. This study compared the amount of anterior tibial translation in the eccentric and concentric phase of the lunge and seated knee extension in anterior cruciate ligament deficient and intact knees.
Methods: Using a non-probability sampling method, 14 men with unilateral anterior cruciate ligament rupture were selected for participation in this cross-sectional study. Participants were recruited from the university’s physiotherapy clinics. A uni-plane fluoroscope was used to image the knee joint while participants performed the forward lunge and open-kinetic knee extension exercises with the intact and injured legs in random order. Fluoroscopy imaging was performed in the radiology center at Sina Hospital, Tehran, Iran, from September 2013 to February 2014. Two factorial mixed ANOVA was used to analyze the data.
Results: There were no significant differences in the anterior tibial translation between the limbs and contraction phases during the lunge exercise. During open-kinetic knee extension, the anterior tibial translation in anterior cruciate ligament deficient knees was significantly more than that of healthy knees at 0⁰ (P=0.007). The anterior tibial translation in the eccentric phase of open-kinetic knee extension at flexion angles of 0⁰ (P=0.049) and 15⁰ (P=0.024) was significantly greater than that in the concentric phase.
Conclusion: In the lunge exercise, the amount of anterior tibial translation was similar between the eccentric and concentric phases and the intact and anterior cruciate ligament deficient knees, however, during open-kinetic knee extension exercise, in the eccentric phase was greater than that in concentric, and in the intact knees was greater than that in the intact knees, at 0-15⁰ angles.

Abstract
Background: Recently, the surgical methods are used in patients with anterior cruciate ligament rupture and have been associated with successful results. There are different results in the term of using of the surgical methods for anterior cruciate ligament that often is associated with some complications such as infection, static laxity, remaining the pain, need to recurrence surgery, and limitation in the range of motion. Therefore, in this study, we aimed to compare outcomes of anterior cruciate ligament reconstruction with the fixed loop and the adjustable loop.
Methods: This cross-sectional study was done on 60 patients undergoing anterior cruciate ligament reconstruction referred to Kashani Hospital of Isfahan, Iran, from March 2017 to February 2019. Also, this study was approved in the Isfahan University of Medical Sciences, Isfahan, Iran. 30 patients were assigned to a fixed loop and 30 patients under the adjustable loop method. Postoperative outcomes were compared with the fixed loop group and the adjustable loop group.
Results: The frequency of static laxity below 8 mm in the fixed loop group was 83.3% and the frequency of static laxity below 8 mm in the adjustable loop was 76.7%. There was no significant difference between the fixed loop group and the adjustable loop group based on static laxity. Also, no infection was seen in the fixed loop group and the adjustable loop group. There was no significant difference between the fixed loop group and the adjustable loop group in terms of range of motion and knee score before and after surgery. After surgery, 96.7% of the fixed loop group and 86.7% of the adjustable loop group returned to normal activity. There was no significant difference between the fixed loop group and the adjustable loop group in terms of return to normal activity and satisfaction.
Conclusion: Using the fixed loop is effective, useful, and with low-complication for the patients with anterior cruciate ligament and also using the adjustable loop grafts is effective, useful, and with low-complication for the patients with the anterior cruciate ligament rupture.
