- Published papers on anatomic anterior cruciate ligament (ACL) reconstruction often lack details in the description of the surgical procedure, and there are large variations in anatomic ACL reconstruction techniques. We aimed to develop a validated checklist to be used for anatomic ACL reconstruction. First, a list of all potential items that could be used in the checklist was generated. Thirty-four ACL experts were selected to participate in an anonymous online survey to rate the importance of these items on a scale of 1 to 4 (with a score of 4 having the most importance). The results were verified by surveying a large sample of 959 orthopaedic specialists who are peer reviewers for four major orthopaedic journals. Items were included in the final checklist if they received an importance score of 3 or 4 from at least 75% of the survey takers. The survey response rate was 79% (twenty-seven of thirty-four) of the ACL experts and 40% (379 of 959) of the peer reviewers. The final Anatomic ACL Reconstruction Checklist includes seventeen items with a maximum score of 19 points. The final checklist underwent preliminary testing for internal consistency, intertester reliability, and validity. Cronbach's alpha for internal consistency was 0.82, and the intraclass correlation coefficient (ICC) for intertester reliability was 0.65. This large survey-based study on anatomic ACL reconstruction resulted in the development of the Anatomic ACL Reconstruction Checklist; preliminary evidence for interpretation of the scores is provided.

- PURPOSE: One of the templates in the development of "anatomic" anterior cruciate ligament (ACL) reconstruction has been basic science studies focusing on comparing various aspects of ACL reconstruction in order to optimize surgical technique. However, often such papers lack necessary data in the methods section to ascertain the proposed surgical technique as anatomic. The goal of this systematic review was to evaluate basic science studies on anatomic ACL reconstruction. METHODS: A systematic electronic search was performed using the MEDLINE and EMBASE databases. Studies that were published from January 1995 to April 2009 were included. Only basic science studies on human cadavers that reported "anatomic" ACL reconstruction and written in English were included. Variation in surgical technique and reporting of surgical description were assessed. RESULTS: Eighteen studies were included in this systematic review. Only the fixation method, graft type and tension pattern were reported in the majority studies. Notchplasty and radiographic documentation were grossly underreported. Other surgical data were reported at best in two-thirds of the studies. There was a large variation in the reported surgical techniques among the included studies. Due to the aforementioned, it was not deemed possible to pool data of the included studies. CONCLUSION: For most variables in the surgical technique description, there was sizeable underreporting resulting in an inability to pool the outcomes. To provide literature that holds up to the current high level of medical research, authors are encouraged to report their surgical technique in a thorough manner, similar to high-level clinical trials. LEVEL OF EVIDENCE: Systematic review, Level II.

- The anterior cruciate ligament has been and is of great interest to scientists and orthopaedic surgeons worldwide. Anterior cruciate ligament reconstruction was initially performed using an open approach. When the approach changed from open to arthroscopic reconstruction, a 2- and, later, 1-incision technique was applied. With time, researchers found that traditional arthroscopic single-bundle reconstruction did not fully restore rotational stability of the knee joint and a more anatomic approach to reconstruct the anterior cruciate ligament has been proposed. Anatomic anterior cruciate ligament reconstruction intends to replicate normal anatomy, restore normal kinematics, and protect long-term knee health. Although double-bundle anterior cruciate ligament reconstruction has been shown to result in better rotational stability in both biomechanical and clinical studies, it is vital to differentiate between anatomic and double-bundle anterior cruciate ligament reconstruction. The latter is merely a step closer to reproducing the native anatomy of the anterior cruciate ligament; however, it can still be done nonanatomically. To evaluate the potential benefits of reconstructing the anterior cruciate ligament in an anatomic fashion, accurate, precise, and reliable outcome measures are needed. These include, for example, T2 magnetic resonance imaging mapping of cartilage and quantification of graft healing on magnetic resonance imaging. Furthermore, there is a need for a consensus on which patient-reported outcome measures should be used to facilitate homogeneous reporting of outcomes.

- BACKGROUND:There have been numerous studies on anterior cruciate ligament (ACL) reconstruction. Considering the vast number of studies, a quick assessment reveals rather few with a high level of evidence. PURPOSE:The primary aim was to categorize the study type and level of evidence of studies on primary ACL reconstruction by applying the level of evidence rating system proposed by the Oxford Centre for Evidence-Based Medicine. The secondary aims were to correlate the level of evidence with the impact factor of the journal, to evaluate the level of evidence over time, and to evaluate the geographic distribution of the included studies. STUDY DESIGN:Systematic review. METHODS:An electronic search was performed using the databases PubMed, EMBASE, and Cochrane Library. Studies published from January 1995 to August 2011 were included. Therapeutic studies written in English that report on isolated primary ACL reconstruction with clinical outcome measurements related to the reconstruction were included. Categorization and implementation of the level of evidence were performed. Correlation between the level of evidence and the impact factor of the journal was analyzed together with linear regression models to reveal any significant trends over time. RESULTS:A total of 7154 studies were analyzed, of which 1510 were included. Analysis of the study types revealed that case series (n = 494; 32.7%) was the most frequent study type. Randomized controlled trials represented 9.2% (n = 139) of the sample, whereas meta-analyses were rare. Single-bundle studies were the most common studies (n = 1333; 88.3%), followed by double-bundle (n = 98; 6.5%) and single- versus double-bundle (n = 79; 5.2%). The journals Arthroscopy, Knee Surgery Sports Traumatology Arthroscopy (KSSTA), and American Journal of Sports Medicine (AJSM) represented 43.5% (n = 657) of the included studies. Arthroscopy had the highest number of publications in general and in level 4 and 5 studies, whereas AJSM had the lowest number of the 3. AJSM had the highest number of level 1 and 2 studies in general. The mean level of evidence calculated without level 5 studies was 3.15 for Arthroscopy, 3.20 for KSSTA, and 2.9 for AJSM. There was a significant correlation (P < .05) between the impact factor of the journal and mean level of evidence of the journal and the proportion high level of evidence studies (levels 1 and 2). There was a significant (P < .05) trend toward higher mean level of evidence over time. CONCLUSION:Most therapeutic studies on primary ACL reconstruction were of low level of evidence, and there was a positive correlation between the journal's impact factor and the mean level of evidence and the proportion of high level of evidence studies. There was significant trend toward higher mean level of evidence over time.
