Few authors have studied the effects of gender on the outcome of ACL reconstruction in athletes. This retrospective- prospective study compared the treating results using the patellar tendon (LP) and hamstring (StG) techniques in men and women. We followed 40 athletes (23 males, 17 females) from population of 120 patients operated at Institute for Orthopedic Surgery Banjica". There were 13 males and 7 females in the LP group and 11 males and 9 females in the StG group. Patients were operated by the same surgeons within 6 month from injury and underwent the same rehabilitation program. After an average of 24 months they were assessed by clinical evaluation, knee laxity analysis and standard knee scores. Among LP patients there were no significant differences between males and females regarding knee evaluation form, laxity or functional tests. Females in the hamstring group had significantly grater laxity and significantly higher deficit in flexion and extension. We suggest further studies on the clinical significance of these findings, particularly on their ramifications of return to sports and rehabilitation of female athletes.

Objective: This study aims to compare the functional tests after anterior cruciate ligament reconstruction (ACLR) with and without meniscal repair after the rehabilitation program and before returning to sports. Material and Methods: Patients who underwent ACLR using hamstring tendon autograft during 2016-2017 were invited to participate in this study and divided into 2 groups including with and without meniscal repairs according to the surgical reports. A group of ACLR with meniscal repair required the conservative anterior cruciate ligament (ACL) rehabilitation program because the non-weight-bearing approach should be applied during the first 6 weeks. These patients were followed up clinically until the rehabilitation program finished. The functional tests were applied with the 4 single-leg hop tests, as reported in the limb symmetry index (LSI). Results: Forty-three patients were enrolled in the program. These patients were divided into 2 groups: ACLR with meniscal repair (n=20) and ACLR without meniscal repair (n=23). It was found that there was no statistically significant difference between the two groups with respect to duration for completing the rehabilitation program (p-value=0.38). Also, there was no statistically significant difference between the two groups with respect to the LSI of all 4 singleleg hop tests of duration for completing the rehabilitation program. Conclusion: The conservative ACL rehabilitation program after meniscal repair surgery did not affect the function tests in terms of duration for completing the rehabilitation program before return to sports (RTS).

Female athletes are more likely to sustain an anterior cruciate ligament (ACL) injury than male athletes. Previous study has showed that female individuals had larger anterior knee laxity than their male counterparts [1]. Researchers have also reported that knee laxity and hyperextension knee were a possible factor contributing to ACL injury [2]. Loudon showed that a person with hyperextension knee, either healthy or ACL-injured, had poorer proprioceptive control. Even more, ACL-injured subjects with hyperextension knee demonstrated a declined function of proprioception feedback loop and the ability to initiate protective reflexes [3].

Background Patellar and hamstring tendon autografts are the most frequently used graft types for anterior cruciate ligament reconstruction, but few direct comparisons of outcomes have been published. Hypothesis There is no difference in outcome between the two types of reconstruction. Study Design Prospective randomized clinical trial. Methods After isolated anterior cruciate ligament rupture, 65 patients were randomized to receive either a patellar tendon or a four-strand hamstring tendon graft reconstruction, and results were reviewed at 4, 8, 12, 24, and 36 months. Results Pain on kneeling was more common and extension deficits were greater in the patellar tendon group. There were greater quadriceps peak torque deficits in the patellar tendon group at 4 and 8 months but not thereafter. In the hamstring tendon group, active flexion deficits were greater from 8 to 24 months, and KT-1000 arthrometer side-to-side differences in anterior knee laxity at 134 N were greater. Cincinnati knee scores, International Knee Documentation Committee ratings, and rates of return to preinjury activity levels were not significantly different between the two groups. Conclusions Both grafts resulted in satisfactory functional outcomes but with increased morbidity in the patellar tendon group and increased knee laxity and radiographic femoral tunnel widening in the hamstring tendon group.

Background Recently, more anatomic anterior cruciate ligament reconstructions have been developed to improve knee laxity. Purpose The objective of this study is to assess knee kinematics after double-bundle reconstruction with hamstring tendon and after anatomically oriented reconstruction with a patellar tendon using navigation during surgery. Study Design Cross-sectional study; Level of evidence, 3. Methods Eighty knees received double-bundle reconstruction with a hamstring tendon graft, and 45 knees received anatomically oriented reconstruction with a patellar tendon graft. Before reconstruction, knee laxity was measured using a navigation system. After the posterolateral bundle or anteromedial bundle was temporarily fixed during double-bundle reconstruction, knee laxity was measured to assess the function of each bundle. After double-bundle reconstruction or anatomically oriented reconstruction with patellar tendon, knee laxity was measured in the same manner. Results Both double-bundle reconstruction and anatomically oriented reconstruction similarly improved knee laxity compared With before reconstruction in all knee flexion angles. Regarding the function of the anteromedial and posterolateral bundles in double-bundle reconstruction, the 2 grafts showed contrasting behavior. The posterolateral bundle restrained tibial displacement mainly in knee extension, whereas the anteromedial bundle restrained it more in the knee flexion position. The posterolateral bundle has a more important role in controlling rotation of the tibia than the anteromedial bundle. Conclusion Although the posterolateral bundle has an important role in the extension position, the anteromedial bundle is more important in the flexion position. Therefore, both bundles should be reconstructed to improve knee laxity throughout knee range of motion. Even with single-bundle reconstruction using a patellar tendon, anatomic reconstruction might improve knee laxity similar to double-bundle reconstruction.

Background: despite the large number of works covering the rupture of the anterior cruciate ligament of the knee joint, today there are no generally accepted tactics of physical therapy after this injury. The issue of staged rehabilitation of persons after autoplasty of the anterior cruciate ligament needs to be clarified. Objective: to develop an effective program of complex physical therapy for persons after autoplasty of the anterior cruciate ligament at the follow-up stage based on comparisons of rehabilitation programs of the two medical centers. Materials and Methods. The clinical trial involved 26 patients of different ages and genders from two medical centers (by 13 subjects) at the follow-up stage after autoplasty of the anterior cruciate ligament. Original rehabilitation program with using crossovers, balancing platforms, massage rollers, kinesiotaping and CPM was developed. Amplitude of knee flexion and extension, manual and muscular testing and some cardiovascular parameters (heart rate, systolic and diastolic blood pressure) were analyzed before and after the rehabilitation program in all participants from medical center 1 (original program) and for all participants from medical center 2 (standard program). Standard statistics was used to describe and compare the results. Results: After the course of therapy, the patients in both centers achieved the same rates of active flexion and extension of the knee, but patients from the 1 medical center reached them on average 5-6 weeks after the start of therapy. Conclusions: There is an advantage of using a comprehensive program of physical therapy (with using multi-function simulators, balancing platforms, massage rollers, kinesio-taping and CPM simulators) for individuals after autoplasty of the anterior cruciate ligament at the follow-up stage.
