Abstract
INTRODUCTION A lot of research addresses superiority of the two commonly used autografts bone-patellar tendon-bone (BPTB) and hamstring tendon for anterior cruciate ligament (ACL) reconstruction, without getting to consensus. While there are numerous studies and reviews on short- to mid-term follow-up, not much literature is available on long-term follow-up. As patients suffering ACL injuries are often of young age and high athletic activity, it is crucial to have the best evidence possible for graft choice to minimize consequences, like osteoarthritis later on. MATERIALS AND METHODS A search of the online databases, PubMed and Embase, was carried out last on 31st March 2022 for studies comparing BPTB and hamstring tendon (HT) autografts for ACL reconstruction in human patients with a minimum follow-up of 10 years. The methodological quality of each study has been evaluated using the modified Coleman Methodology Score. Results on the three variables patient-oriented outcomes, clinical testing and measurements and radiographic outcomes were gathered and are presented in this review. RESULTS Of 1299 records found, nine studies with a total of 1833 patients were identified and included in this systematic review. The methodological quality of the studies ranged from a Coleman Score of 63-88. Many studies reported no or only few statistically significant differences. Significant results in favour of BPTB were found for activity levels and for instrumented laxity testing with the KT-1000 arthrometer. Better outcomes for HT were found in IKDC-SKF, the KOOS, donor site morbidity, pivot shift test, radiographic osteoarthritis (IKDC C or D) and contralateral ACL rupture. No studies presented significant differences in terms of Lysholm Score or Tegner Activity Score, Lachman test, single-legged hop test, deficits in range of motion, osteoarthritis using the Kellgren and Lawrence classification or graft rupture. CONCLUSION We cannot recommend one graft to be superior, since both grafts show disadvantages in the long-term follow-up. Considering the limitation of our systematic review of no quantitative analysis, we cannot draw further conclusions from the many insignificant results presented by individual studies.

Abstract
Aim: Due to anatomic, biomechanical, kinematic, biological and clinical data obtained as a result of many studies related to treatment and rehabilitation of injuries to the anterior cruciate ligament (ACL), among the most studied anatomic structures in the human body, the literature is continuously being updated and improved. In this study, the aim was to holistically analyze scientific articles about the ACL published between 1980 and 2021 using a variety of statistical methods.
Material and Method: Articles published from 1980 to 2021 about the ACL were obtained from the Web of Science (WoS) database and analyzed using statistical methods and bibliometric approaches. To identify trend topics and global cooperation, and to complete citation analysis, network visualization maps were used. The exponential smoothing predictor was used to predict the number of articles that will be published in the next 5 years. Spearman’s correlation coefficient was used for correlation research.
Results: A total of 11,077 publications were identified. Of these publications, 9101 (82.1%) were articles. The top 3 countries contributing most to the literature were the USA (3894, 42.7%), Japan (879, 9.6%) and Germany (616, 6.7%). The top 3 active organizations were Pennsylvania Commonwealth System of Higher Education (n=468), University of Pittsburgh (440), and University of California system (279). The top 3 journals publishing most articles were the American Journal of Sports Medicine (n=1614), Knee Surgery Sports Traumatology Arthroscopy (1418), and Arthroscopy: The Journal of Arthroscopic and Related Surgery (915). The most effective journal according to mean number of citations per article was the Journal of Bone and Joint Surgery (average citation per document: 80.7). The most active author was Freddie H. Fu (n=278, from University of Pittsburgh).
Conclusion: In this comprehensive bibliometric research about the topic of ACL, with a trend toward increasing publication numbers in recent years, the summary information for 9101 articles published between 1980 and 2021 was shared. According to analysis results to determine trend topics, the keywords studied in recent years include return to sport, ACL injury, anterolateral ligament, pivot shift, quadriceps strength, KOOS, ACL tear, ACL repair, meniscal repair, knee ligaments, tibial slope, posterior tibial slope, return to play, adolescent, graft failure and lateral meniscus.

Persistent knee extension deficits are common after anterior cruciate ligament reconstruction: a systematic review and meta-analysis of randomised controlled trials. Knee Surg Sports Traumatol Arthrosc 2023:10.1007/s00167-022-07299-3. [PMID: 36705690 DOI: 10.1007/s00167-022-07299-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Accepted: 12/20/2022] [Indexed: 01/28/2023]
Abstract
PURPOSE Knee extension deficits complicate recovery from ACL injury and reconstruction; however, the incidence of knee extension loss is not well defined. The aim of this review was to identify the incidence of loss of extension (LOE) following ACL rupture and reconstruction, explore the definitions of knee extension deficits reported and identify prognostic factors affecting LOE incidence. METHODS A systematic search was conducted in Medline, Cochrane Library and PEDro for studies in publication up to November 2021, with no restrictions on publication year. References were screened and assessed for inclusion using predetermined eligibility criteria. Randomised controlled trials (RCTs) that quantified knee angle, loss of extension or incidence of extension deficit were included for quality assessment and data extraction. Statistical summaries were generated and meta-analyses performed in two parts to examine: (i) the probability of a datapoint being zero incidence compared to a nonzero incidence and (ii) the relationship between the predictors and nonzero LOE incidence. RESULTS A sample of 15,494 studies were retrieved using the search criteria, with 53 studies meeting eligibility criteria. The pooled results from 4991 participants were included for analysis, with 4891 participants who had undergone ACLR. The proportion of included studies judged at an overall low risk of bias was small (7.8%). The observed group and study were the most important predictors for whether a datapoint reported an incidence of extension deficit. Time to follow-up (P < 0.001) and graft type (P = 0.02) were found to have a significant influence on nonzero LOE incidence (%). Covariate adjusted estimates of average LOE indicated 1 in 3 patients presenting with LOE at 12 month follow-up, reducing to 1 in 4 at 2 years. CONCLUSIONS This review examined the definitions for the measurement and interpretation of postoperative knee extension and established the trajectory of knee extension deficit after ACL injury and reconstruction. While factors associated with loss of extension were identified, the exact trajectory of knee extension deficits was difficult to infer due to discrepancies in measurement techniques and patient variation. On average, 1 in 3 patients may present with loss of extension of at least 3 degrees at 12-month follow-up, decreasing to 1 in 4 at 2 years. These results may be used by clinicians as an upper threshold for acceptable complication rates following ACLR. Future work should focus on LOE as a clinically relevant complication of ACL injury and treatment with appropriate attention to standardisation of definitions, measurements and better understanding of natural history.

Abstract
Purpose To compare subjective outcomes and complications of anterior cruciate ligament reconstruction (ACLR) using either bone–patellar tendon–bone (BPTB) or quadriceps tendon (QT) autograft. Methods A retrospective analysis of prospectively collected data identified consecutive cohorts of patients undergoing ACLR with either BPTB or QT autograft. Patients with less than 12-month follow-up and those undergoing concomitant osteotomies, cartilage restoration, and/or other ligament reconstruction procedures were excluded. Pre- and postsurgical patient-reported outcomes including International Knee Documentation Committee, Knee Injury and Osteoarthritis Outcome Score, Patient-Reported Outcomes Measurement Information System (PROMIS), Single Assessment Numeric Evaluation, Tegner, and Marx were compared between groups. Complications requiring reoperation were recorded. Results One hundred nineteen patients met inclusion criteria, including 39 QT autografts and 80 BPTB autografts. Demographic information was comparable between groups. Mean follow-up was comparable between groups (QT 22.4 ± 10.6 months vs BPTB 28.5 ± 18.5 months, P = .06). At minimum 12-month follow-up (range 12.0-100.8 months), patients in both groups demonstrated statistically significant improvements in International Knee Documentation Committee (QT 60.0%, P < .0001; BPTB 57.7%, P < .0001), all Knee Injury and Osteoarthritis Outcome Score domains, PROMIS Mobility T-Score (QT 27.2%, P = .0001; BPTB 23.2%, P < .0001), PROMIS Global Physical Health (QT 14.4%, P = .002; BPTB 13.4%, P = .001), PROMIS Physical Function (QT 29.6%, P < .0001; BPTB 37.1%, P < .0001), PROMIS Pain Interference (QT –16.5%, P < .0001; BPTB –20.8%, P < .0001), Single Assessment Numeric Evaluation, (QT 76.9%, P < .0001; BPTB 73.3%, P < .0001), Tegner (QT 92.9%, P = .0002; BPTB 101.4%, P < .0001), and Marx (QT –26.6%, P = .02; BPTB –32.0%, P = .0002) with no statistically significant differences between the 2 groups. Overall postoperative reoperation rate did not differ between groups (QT 12.8% vs BPTB 23.8%, P = .2). Revision ACL reconstruction rate did not differ between groups (QT 5.1% vs BPTB 7.5%, P = .6). Conclusions Patients undergoing autograft ACLR with either BPTB or QT demonstrated significant subjective improvements in patient-reported outcomes from preoperative values and no statistically significant differences in outcomes between the groups. Complication and revision ACLR rates were similar between the 2 groups. Level of Evidence III, retrospective cohort study.

Abstract
PURPOSE The aim of this systematic review was to evaluate the impact of bone grafting of patellar defects on reported anterior knee morbidity and subjective outcomes after bone-patellar tendon-bone autograft reconstruction of the anterior cruciate ligament. METHODS A systematic electronic search of MEDLINE, Embase, Web of Science, and the Cochrane Library was carried out. All English-language prospective randomized clinical trials published from January 1, 2000, to July 24, 2020, were eligible for inclusion. All studies addressing patellar defect grafting were eligible for inclusion regardless of the timing of surgery, graft type, surgical technique, or rehabilitation protocol. RESULTS A total of 39 studies with 1,955 patients were included for analysis. There were 796 patients in the no patellar grafting (NPG) group, with a mean age range of 22.7 to 33.0 years, and 1,159 patients in the patellar grafting (PG) group, with a mean age range of 17.8 to 34.7 years. The visual analog scale pain score ranged from 1.2 to 5.1 in the NPG group compared with 0.3 to 3.7 in the PG group. The proportion of patients with anterior knee pain ranged from 19% to 81% in the NPG group and from 15% to 32% in the PG group. Moderate to severe kneeling pain was reported in 22% to 57% of patients in the NPG group and 10% of those in the PG group. The percentage of patients with at least 3° of extension loss ranged from 4% to 43% in the NPG group and from 2% to 11% in the PG group. CONCLUSIONS PG favors decreased anterior knee pain, kneeling pain, and extension loss compared with non-grafted defects; however, the functional outcomes are comparable. Owing to the heterogeneity in reporting, statistical conclusions could not be drawn. LEVEL OF EVIDENCE Level II, systematic review of Level I and II studies.

Abstract
OBJECTIVES To compare the long-term prognosis of patients with different types of grafts used in anterior cruciate ligament reconstruction (ACLR). METHODS PubMed, Ovid (MEDLINE and Embase) and the Cochrane library were searched up to Feb 2020. Eligible studies about different grafts in ACLR were searched for identifying the evidence comparing the long-term (mean or median follow-up time or the general description of the follow-up time≥2 years) knee outcomes of different grafts for ACLR. The final included articles and evaluation criteria were confirmed by the authors and senior clinicians to ensure the validity of the included articles. Lysholm score, the results of pivot shift test, Lachman test and International Knee Documentation Committee (IKDC) evaluation were selected as prognostic indicators. A Bayesian network meta-analysis was conducted. RESULTS A total of 30 articles were included in our network meta-analysis. Finally, we found that artificial graft or augmentation can provide the not bad Lysholm score but the worse result of IKDC evaluation for patients with ACLR compared with other types of grafts. Double-bundle hamstring autograft can provide a good Lysholm score as well as lower positive rate of pivot shift test and Lachman test. Patellar tendon autograft can provide the better result of IKDC evaluation. The patients with allogeneic tendon graft may get the higher positive rate of pivot shift test and Lachman test. Patients with single-bundle hamstring autograft may get the ordinary result of IKDC evaluation and Lysholm score. CONCLUSIONS Double-bundle hamstring autograft may be a better choice because of more items of good prognosis for the patients with ACLR. Patellar tendon autograft is a right choice which only shows the disadvantage on the Lysholm score. The prognosis of patients with single-bundle hamstring autograft is ordinary. The effect of artificial graft or augmentation needs more evidence to prove. Allogeneic tendon graft is not a better choice when compared with other grafts referred in our network meta-analysis. TRANSLATIONAL POTENTIAL STATEMENT In this study, we made a comprehensive comparison of the grafts commonly used in anterior cruciate ligament reconstruction. The evidence presented in this study provides a reference for clinicians to select a suitable anterior cruciate ligament graft.

Abstract
BACKGROUND Anterior cruciate ligament (ACL) injury can lead to reduced function, meniscal lesions, and early joint degeneration. Preservation of a torn ACL using the Internal Brace technique might re-establish normal knee kinematics, avoid donor-site morbidity due to tendon harvesting, and potentially maintain proprioception of the knee. METHODS Fifty subjects were recruited for this study between December 2015 and October 2016. Two groups of individuals who sustained a unilateral ACL rupture were included: those who underwent surgery with preservation of the injured ACL (Internal Brace technique; IB) and those who underwent ACL reconstruction using a hamstring tendon graft (all-inside technique; AI). Subjective self-administered scores were used: the German version of the IKDC Subjective Knee Form (International Knee Documentation Committee), the German version of the WOMAC (Western Ontario and McMaster Universities Arthritis Index), SF-36 (short form), the German version of the KOOS (Knee Osteoarthritis Outcome Score), and the German version of themodified Lysholm Score by Lysholm and Gillquist. Anterior tibial translation was assessed using the KT-1000 Arthrometer (KT-1000 Knee Ligament Arthrometer, MEDmetric Corp., San Diego, CA, USA). Magnetic resonance evaluation was performed in all cases. RESULTS Twenty-three subjects (46 %) were men, and the mean age was 34.7 years. The objective IKDC scores were "normal" in 15 and 14 patients, "nearly normal" in 11 and 7 patients, and "abnormal" in 1 and 2 patients, in the IB and AI groups, respectively. KT-1000 assessment showed a sideto-side difference of more than 3 mm on maximum manual testing in 11 (44 %) and 6 subjects (28.6 %) in the IB and AI groups, respectively. In the postoperative MRI, 20 (74 %) and 22 subjects (96 %) in the IB and AI groups had an intact ACL. Anterior tibial translation was significantly higher in the IB group compared with the AI group in the manual maximum test. CONCLUSIONS Preservation of the native ACL with the Internal Brace primary repair technique can achieve comparable results to ACL reconstruction using Hamstring autografts over a short term. Clinically relevant limitations such as a higher incidence of pathologic laxity, with patients more prone to pivot-shift phenomenon were observed during the study period.

Abstract
Purpose To evaluate the effectiveness of various graft options for anterior cruciate ligament reconstruction using network meta-analysis. Methods A medical literature search was conducted of PubMed, the Cochrane Library, Embase, SCOPUS, and Web of Science from their inception through March 1, 2019. The outcomes, including International Knee Documentation Committee (IKDC) form, Lachman test, Lysholm score, Pivot shift test, and Tegner score, were evaluated among graft options. Data extraction was carried out according to inclusion and exclusion criteria, and a network meta-analysis was performed using STATA 14.0. Results A total of 45 trials with 3992 patients were included. The forest plots revealed no significant differences in IKDC, Lysholm, or Tegner score among the grafts. In Lachman score, a significant difference was found in the comparisons of hamstring tendon allograft (HT-AL) versus patellar tendon autograft (PT-AU) and HT-AL versus hamstring tendon autograft (HT-AU). In pivot shift test, PT-AU was superior to all the other grafts, and quadriceps tendon autograft (QT-AU) was superior to HT-AL and artificial ligament (Art-L) in the number of cases with negative results. According to surface under the cumulative ranking area (SUCRA), PT-AU had the highest probability to be the best intervention in Lachman test and Tegner score; tibialis anterior tendon allograft (TA-AL) in IKDC and Lysholm score; and QT-AU in pivot shift test. Based on the cluster analysis of SUCRA, PT-AU was considered the most appropriate intervention by IKDC and Lachman test. Conclusion This study suggests that PT-AU may be the most appropriate graft for ACL reconstruction according to IKDC and Lachman test results. Level of Evidence Level I, network meta-analysis of randomized controlled trials.

Young age, female gender, Caucasian race, and workers' compensation claim are risk factors for reoperation following arthroscopic ACL reconstruction. Knee Surg Sports Traumatol Arthrosc 2020; 28:2213-2223.

Abstract
PURPOSE Given the increasing incidence of arthroscopic anterior cruciate ligament reconstruction (ACLR), mid- to long-term rates of reoperations were investigated on the ipsilateral knee following ACLR. METHODS New York Statewide Planning and Research Cooperative Systems (SPARCS) database was queried from 2003 to 2012 to identify patients with a primary ICD-9 diagnosis for ACL tear and concomitant CPT code for ACLR. Patients were longitudinally followed for at least 2 years to determine incidence and nature of subsequent ipsilateral knee procedures. RESULTS The inclusion criteria were met by 45,231 patients who had undergone ACLR between 2003 and 2012. Mean age was found to be 29.7 years (SD 11.6). Subsequent ipsilateral outpatient knee surgery after a mean of 25.7 ± 24.5 months was performed in 10.7% of patients. Revision ACLR was performed for nearly one-third of reoperations. Meniscal pathology was addressed in 58% of subsequent procedures. Age 19 or younger, female gender, worker's compensation (WC) insurance, and Caucasian race were identified as independent risk factors for any ipsilateral reoperation. An initial isolated ACLR and initial ACLR performed by a high-volume surgeon were found to be independently associated with lower reoperation rates. Tobacco use was not significant. Survival rates of 93.4%, 89.8% and 86.7% at 2-, 5- and 10 years, respectively, were found for any ipsilateral reoperation. CONCLUSION A 10.7% ipsilateral reoperation rate at an average of 25.9 (SD 24.5) months after ACLR and an overall ACLR revision rate of 3.1% were demonstrated by the analysis.

All-Inside Quadrupled Semitendinosus Autograft Shows Stability Equivalent to Patellar Tendon Autograft Anterior Cruciate Ligament Reconstruction: Randomized Controlled Trial in Athletes 24 Years or Younger. Arthroscopy 2020; 36:1629-1646. [PMID: 32059954 DOI: 10.1016/j.arthro.2020.01.048] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2019] [Revised: 12/20/2019] [Accepted: 01/18/2020] [Indexed: 02/02/2023]
Abstract
PURPOSE To compare clinical outcomes of knee anterior cruciate ligament (ACL) autograft reconstruction using all-inside quadrupled semitendinosus (AIST) versus bone-patellar tendon-bone (BPTB) in a high-risk athletic population 24 years or younger. METHODS Skeletally mature candidates younger than 24 years old with an ACL tear were randomized into either the AIST (n = 32) or BPTB (n = 32) group and were followed for 2 years. Magnetic resonance imaging scans were obtained at 1-year follow-up, and radiographs were obtained at 2-year follow-up. All surgeries were performed by a single surgeon using an anteromedial portal to establish the femoral tunnel. The primary outcome measure was KT-1000 stability testing. Secondary outcome measures included International Knee Documentation Committee (IKDC) Knee Evaluation Form, IKDC Subjective Form, Knee Injury and Osteoarthritis Outcome Score, Marx Activity Scale, visual analog pain scale, and SF-12 (Mental and Physical). RESULTS At 2-year follow-up, no statistical difference existed with KT-1000-measured side-to-side laxity between AIST (0.3 ± 0.7 mm, 95% confidence interval 0.0-1.0 mm) and BPTB (0.0 ± 0.8 mm, confidence interval CI -0.3 to 1.1 mm) (P = .197). In addition, no statistical differences between the groups were found for IKDC Subjective Form, Knee Injury and Osteoarthritis Outcome Score, Marx, SF-12 Mental, SF-12 Physical, or with regards to imaging findings. Patients with BPTB reported significantly greater postoperative pain scores at days 2 (P = .049), 3 (P = .004), and 7 (P = .015) and had significantly greater kneeling pain at 2 years (P < .019). A return to sport questionnaire at 2 years revealed no significant difference between the groups for returning to preoperative level of sport activity (83% AIST, 74% BPTB; P = .415). Two graft retears (7%; P = .222) occurred in the AIST group. Three patients in the BPTB group experienced ACL tears in the contralateral knee (9%; P = .239). CONCLUSIONS ACL reconstruction with an all-inside quadrupled semitendinosus autograft construct is equivalent to patellar BPTB autograft based on KT-1000 stability testing in athletes 24 years or younger. LEVEL OF EVIDENCE randomized controlled trial with 92% 2-year follow-up, Level I.

Abstract
BACKGROUND The type of graft for anterior cruciate ligament (ACL) reconstruction is still a topic of debate and there is still no clear consensus on the ideal graft for ACL reconstruction. PURPOSE This study was conducted to compare the outcome of ACL reconstruction surgery between hamstring tendon graft and bone-patellar tendon-bone (BPTB) graft. MATERIALS AND METHODS One hundred and sixty professional athletes were enrolled in the study. They were divided into two groups by computerized randomization. In Group I, ACL reconstruction was done using BPTB graft, and in Group II, ACL reconstruction was done using semitendinosus gracilis graft with preserved tibial insertion (STGPI). Postoperatively, patients were assessed for knee stability, Lysholm score, and WOMAC score. RESULTS Mean KT-1000 side-to-side difference at 1 year was 2.31 ± 1.68 mm in BPTB cohort and 2.52 ± 1.6 mm in STGPI cohort (P = 0.4); and at 2 years, it was 1.98 ± 1.62 mm in BPTB cohort and 2.23 ± 1.6 mm in STGPI cohort (P = 0.4). Mean Lysholm score at 2 years was 96.1 ± 5.81 in STGPI cohort and 97.3 ± 4.62 in BPTB cohort (P = 0.15). Mean WOMAC score at 2 years was 3.3 ± 2.76 in STGPI cohort and 2.84 ± 2.21 in BPTB cohort (P = 0.25). Graft rupture rate was 3.75%; 3 patients in each group had graft rupture. Kneeling pain was present in 15% (12/80) of patients with BPTB graft whereas none of the patients in STGPI cohort had kneeling pain. CONCLUSION There was no difference between two grafts in term of knee stability, visual analog scale score and functional outcome. However, hamstring tendon graft is associated with less donor site morbidity.

Abstract
ABSTRACT Introduction: Anterior cruciate ligament injury is one of the most prevalent musculoskeletal injuries. Therefore, several surgical techniques and graft types have been described for its reconstruction. Autologous hamstring tendon graft is one of the most frequently used, but use of the quadriceps tendon graft has gained prominence in recent years. Objective: To review the literature to compare the outcomes of patients undergoing anterior cruciate ligament reconstruction (ACLR) with quadriceps tendon (QT) autograft versus hamstring tendon (HT) autograft. Methods: A literature review was conducted through PubMed to locate studies (Level of evidence I-III) comparing the outcomes of the QT autograft vs. the HT autograft in patients undergoing primary ACL reconstruction. Patients were assessed on the basis of re-rupture rate, ligament instability, patient-reported outcome scores, previous pain, and isokinetic tests. Results: Six studies were selected according to inclusion criteria. A total of 481 patients were evaluated, 243 in the QT group and 238 in the HT group. The total re-rupture rate was 1.6% (8 of 481), with 6 in the HT group and 2 in the QT group, but with no statistical difference between groups. One study found increased ligament instability in the HT group and another study found greater instability in the QT group, both with statistical significance. Regarding the patient-reported functional scores, only 01 study found statistical difference, with better results in the QT group. There was no difference in previous pain between groups in the selected studies. Regarding the isokinetic test, one study found a difference in flexor force in the HT group (p <0.01), with no difference in extensor force, while another two studies found an increased extensor force deficit in the QT group within up to 01 year of follow-up. The flexor/ extensor muscle strength ratio was higher in the QT group in both studies. Conclusion: ACL reconstruction with QT graft presents re-rupture rates, ligament instability, functional scores and donor site morbidity that are similar to the HT graft, in addition to preserving greater flexor force in proportion to extensor force. Level of evidence: IV; Review study.

Superior knee flexor strength at 2 years with all-inside short-graft anterior cruciate ligament reconstruction vs a conventional hamstring technique. Knee Surg Sports Traumatol Arthrosc 2019; 27:3592-3598.

Abstract
PURPOSE To compare the "all-inside technique" for anterior cruciate ligament (ACL) reconstruction using a short, quadrupled semitendinosus tendon (ST4) autograft and suspensory cortical fixation on both the femoral and tibial side vs the "conventional technique" using a semitendinosus/gracilis (ST/G) autograft fixed with a suspensory device on the femoral side and with an interference screw on the tibial side, in terms of clinical and functional outcomes. METHODS A total of 90 patients were enrolled, randomised into two groups, and prospectively followed. Group A comprised 45 patients treated with the all-inside technique and Group B included 45 patients treated with the conventional ACL technique (55 males, 35 females; mean age 28.7 ± 11.3 years). Patients completed the Lysholm knee score, the International Knee Documentation Committee (IKDC) score, the Knee Injury and Osteoarthritis Score (KOOS), and the Knee Society Score (KSS) preoperatively and at 2 years postoperatively. Anterior tibial translation measurement (KT-1000 arthrometer) and isokinetic testing of the operative vs non-operative limb were also conducted and the limb symmetry index (LSI) was determined. RESULTS At 24 months, the Lysholm, IKDC, KOOS, and KSS scores between the two groups were similar (n.s.). Anterior tibial translation between the operative and non-operative knee was also similar among the two groups (n.s.). Patients of Group A had significantly higher mean LSIs in terms of flexor peak torque (1.0 ± 0.1 vs 0.9 ± 0.1; p < 0.001), time-to-peak (0.9 ± 0.1 vs 0.8 ± 0.1; p < 0.001) and total work (0.9 ± 0.1 vs 0.8 ± 0.1; p < 0.001) at 180°/s, and significantly better mean LSI for isometric flexor/extensor ratio at 90° (1.1 ± 0.3 vs 0.8 ± 0.2; p < 0.001). CONCLUSION The all-inside ACL reconstruction with an ST4 autograft and cortical button fixation on both ends is a viable alternative to the conventional technique. It affords preservation of knee flexor strength, which is of advantage, especially when treating athletes with ACL injury. LEVEL OF EVIDENCE I.

Abstract
BACKGROUND Arthroscopic anterior cruciate ligament (ACL) reconstruction with ligament advanced reinforcement system (LARS) had revealed good results with low complication and failure rate in series of studies. The specific candidates for ACL reconstruction with LARS are still unknown anyway. The purpose of this study is to evaluate the activity-related outcome in ACL reconstruction using LARS ligament. METHODS A total of 43 unilateral arthroscopic ACL reconstructions with LARS were collected and divided into two groups: group A (preinjury Tegner score ≥ 6, n = 20) and group B (preinjury Tegner score < 6, n = 23). We had analyzed the stability of knee and functional outcome with a minimum of 2-years follow up. RESULTS All patients were aware of improvement over the knee stability immediately after ACL reconstruction with LARS. The functional outcome of knee was improved in both groups by analysis with the Lysholm score and modified International Knee Documentation Committee (IKDC) score. The postoperative grading of the knee examination form of modified IKDC grade showed no statistical difference in both groups. CONCLUSION Arthroscopic ACL reconstruction with LARS was encouraged as an alternative option even in high sports demand patients.

Abstract
UNLABELLED Disruption of anterior cruciate ligament (ACL) is a common ligamentous injury of the knee. The best choice of graft for reconstruction remains undecided. This prospective, randomized clinical trial aimed to compare clinical results of bone-patellar tendon-bone (BPTB) grafts and four-strand semitendinosus-gracilis (QHT) grafts for ACL reconstruction over a 1-year follow-up interval in Indian population. METHODS 42 consecutive patients with ACL injury were recruited, by pick and draw method and allotted into two groups with 21 patients in each group. Group A patients underwent arthroscopic ACL reconstruction using BPTB graft while QHT autograft was used for patients in Group B. All the patients underwent standard ipsilateral arthroscopic ACL reconstruction procedure using a single incision, antero-medial (AM) portal technique for BPTB or the QHT autograft by a same surgeon. Patients were followed up regularly for a minimum period of 1 year. RESULTS After one year, the Cincinnati score was 91 ± 4.117 in BPTB group and 89.29 ± 5.371 in QHT group (P = 0.282). There was no significant difference between the two groups in the mean scores with respect to pain, overall activity level and running in the Cincinnati score. None of the patients complained of the knee giving way. Similarly, at 1 year, the Lysholm score was 92.84 ± 2.630 and 90.55 ± 2.395 in the two groups respectively (P = 0.842). There were no episodes of locking or instability and there was no significant difference in the mean Lysholm scores regarding pain and squatting. CONCLUSION There was no significant functional difference between the two grafts in terms of Lysholm and the Cincinnati score, anterior knee laxity and altered sensation over proximal leg. The patients with QHT groups performed better than BPTB functionally at 6 month so early return to sport is possible even with QHT autograft.

Abstract
BACKGROUND An infection after anterior cruciate ligament (ACL) reconstruction is a relatively rare but challenging complication. There are no meta-analyses comparing the incidence of infections after ACL reconstruction with the various available graft choices. PURPOSE To compare the incidence of infections after ACL reconstruction with bone-patellar tendon-bone (BPTB) autografts compared with hamstring autografts, with a secondary aim of comparing the incidence of infections after reconstruction with autografts compared with allografts. STUDY DESIGN Meta-analysis. METHODS A systematic review was performed to identify level 1 and 2 studies that reported the incidence of infections by graft type after ACL reconstruction. Studies that evaluated patients undergoing primary ACL reconstruction with an autograft, allograft, or combination of autograft and allograft and reported the number of postoperative infections by graft type utilized were considered for inclusion. Studies were excluded if they included revision ACL reconstruction or did not specify the number of infections by graft type. Study findings were reviewed, and meta-analysis was performed when data were sufficiently homogeneous. RESULTS Twenty-one studies meeting criteria were identified from the literature review. Meta-analysis revealed a significant difference in the incidence of deep infections between BPTB autografts and hamstring autografts, with the BPTB group displaying a 77% lower incidence of infections compared with the hamstring group (relative risk [RR], 0.23; 95% CI, 0.097-0.54). The incidence of infections was 66% lower with BPTB autografts compared with all other graft types, with a pooled RR of 0.33 (95% CI, 0.15-0.71). There was no significant difference in the incidence of infections after ACL reconstruction with autografts compared with allografts (RR, 1.035; 95% CI, 0.589-1.819). CONCLUSION The findings of this meta-analysis demonstrate a significantly lower incidence of deep infections after ACL reconstruction with BPTB autografts compared with hamstring autografts but not compared with allografts. CLINICAL RELEVANCE Although the overall infection rate after ACL reconstruction is relatively low, the significantly higher rate of infections with hamstring autografts compared with BPTB autografts should be a consideration when discussing graft choices for ACL reconstruction.

Abstract
INTRODUCTION The patellar tendon graft has long been the gold standard for ACL reconstruction. Recently semitendinosus and gracilis tendons graft have been used increasingly. We hypothetise that the Bone-Patella Tendon-Bone graft is a good and economical graft for the Indian population with no adverse effects of anterior knee pain or patellar tendon shortening. We believe that the early squatting and cross-legged sitting causes early and constant stretching of the tendon in our patients. This is responsible for the lesser incidences of adverse effects in the Indian population. MATERIAL AND METHOD In a retrospective study, the hospital database was scrutinized to shortlist patients who had undergone a bone-patella tendon-bone harvest for ACL or PCL reconstruction before 2013. Each patient was evaluated using the Lysholm score and the KOOS Score. VAS was also used, to evaluate for the amount of pain experienced by patients. The analysis of the quadriceps power along with the presence or absence of any extensor lag was made too. The modified Insall Salvati index was also calculated. RESULTS Forty-seven patients were shortlisted of which 25 patients were followed up with an average follow up of 94.5 months. Although some patients did complain of occasional pain with the average VAS score of 1.45; on analyzing the data it was evident that all our patients had excellent quadriceps power (5/5) with no extensor lag. The mean Lysholm score was 95.55, while the mean KOOS score was 94.17. The mean Insall index of 1.05 showed no significant patella baja in any of our patients. CONCLUSION It is ascertained that no significant retro-patellar pain or shortening of the patellar tendon occurs following a bone patella tendon bone harvest. The bone patella bone tendon graft is a suitable graft for ligament reconstruction with good functional outcome, and no significant adverse effect of patella baja or anterior knee pain in the Indian patients.

Abstract
Objective This prospective randomized study was performed to compare the outcomes of two operative methods of anterior cruciate ligament (ACL) reconstruction based on either bone–patellar tendon–bone (BTB) grafts or hamstring tendon (HT) grafts. Methods Among 100 patients, 96 completed the full follow-up period and were included in the final analysis (48 in the BTB group and 48 in the HT group). The patients were evaluated preoperatively and 1, 3, 6, and 12 months after ACL reconstruction. The Kujala score, Tegner score, and Knee injury and Osteoarthritis Outcome Score (KOOS) were among the parameters used to evaluate the patients. Results Both groups were comparable in terms of sex, age, and body mass index. None of the analyzed scores were significantly different between the BTB and HT groups at either the initial or last visit. Both groups demonstrated improvement at the 12-year follow-up according to the Kujala score and most categories of the KOOS. The Tegner activity level score showed significant improvement in the HT but not BTB group. Conclusion Patients undergoing ACL reconstruction with BTB and HT grafts show comparable improvement in functional results after 1 year of rehabilitation.

Abstract
BACKGROUND Semitendinosus and gracilis muscles are frequently harvested for autologous tendon grafts for cruciate ligament reconstruction. This study investigated the joint-stabilizing effects of these hamstring muscles in cases of insufficiency of the medial collateral ligament (MCL). HYPOTHESES First, both the semitendinosus and gracilis muscles can actively stabilize the joint against valgus moments in the MCL-deficient knee. Second, the stabilizing influence of these muscles decreases with an increasing knee flexion angle. STUDY DESIGN Controlled laboratory study. METHODS The kinematics was examined in 10 fresh-frozen human cadaveric knees using a robotic/universal force moment sensor system and an optical tracking system. The knee kinematics under 5- and 10-N·m valgus moments were determined in the different flexion angles of the (1) MCL-intact and (2) MCL-deficient knee using the following simulated muscle loads: (1) 0-N (idle) load, (2) 200-N semitendinosus (ST) load, and (3) 280-N (200/80-N) combined semitendinosus/gracilis (STGT) load. RESULTS Cutting the MCL increased the valgus angle under all tested conditions and angles compared with the MCL-intact knee by 4.3° to 8.1° for the 5-N·m valgus moment and 6.5° to 11.9° for the 10-N·m valgus moment ( P < .01). The applied 200-N simulated ST load reduced the valgus angle significantly at 0°, 10°, 20°, and 30° of flexion under 5- and 10-N·m valgus moments ( P < .05). At 0°, 10°, and 20° of flexion, these values were close to those for the MCL-intact joint under the respective moments (both P > .05). The combined 280-N simulated STGT load significantly reduced the valgus angle in 0°, 10°, and 20° of flexion under 5- and 10-N·m valgus moments ( P < .05) to values near those for the intact joint (5 N·m: 0°, 10°; 10 N·m: 0°, 10°, 20°; P > .05). In 60° and 90° of flexion, ST and STGT loads did not decrease the resulting valgus angle of the MCL-deficient knee without hamstring loads ( P > .05 vs deficient; P = .0001 vs intact). CONCLUSION In this human cadaveric study, semitendinosus and gracilis muscles successfully stabilize valgus moments applied to the MCL-insufficient knee when the knee is near extension. CLINICAL RELEVANCE In the valgus-unstable knee, these data suggest that the hamstring muscles should be preserved in (multi-) ligament surgery when possible.

Abstract
BACKGROUND There is no consensus in the current literature on which surgical options render the best long-term results after anterior cruciate ligament (ACL) reconstruction in terms of clinical outcomes and the development of radiographic osteoarthritis (OA). PURPOSE To investigate the long-term clinical and radiographic results after ACL reconstruction using either a patellar tendon (PT) autograft or a hamstring tendon (HT) autograft. STUDY DESIGN Randomized controlled trial; Level of evidence, 2. METHODS This multicenter study was based on 2 previous randomized cohorts consisting of 193 patients who underwent unilateral primary ACL reconstruction using either a PT autograft or an HT autograft. The index surgical procedure was performed between September 1995 and January 2000. Clinical assessments, including knee laxity measurements, functional outcomes, patient-reported outcomes, and bilateral standing radiographs, were performed at the final follow-up examination. RESULTS At the long-term follow-up, 147 (76%) patients were examined: 61 in the PT group and 86 in the HT group. The mean (±SD) follow-up time was 191.9 ±15.1 months for the HT group and 202.6 ± 10.4 months for the PT group. Knee laxity measurements revealed significantly more patients with a normal pivot-shift test finding in the HT group compared with the PT group (71% vs 51%, respectively; P = .048); however, no significant differences were found in terms of the manual Lachman test or the KT-1000 arthrometer manual maximum test. The patients in the PT group had significantly more difficulty knee walking (P = .049). There were no significant differences between the study groups in terms of patient-reported outcomes or range of motion in the reconstructed knee. In both groups, significantly more signs of radiographic OA were found in the reconstructed knee than in the contralateral healthy knee. However, there were no significant differences between the groups in terms of radiographic OA. CONCLUSION Only minor and mostly insignificant differences were found between the PT and HT autograft groups in this long-term randomized controlled trial. In both groups, significantly more signs of radiographic OA were found in the reconstructed knee than in the contralateral knee.

Abstract
One of the goals of the annual American Orthopaedic Association (AOA) meeting is to address controversy, both in leadership and clinical practice. A panel of experts in their respective fields presented the background and literature behind three "myths" in orthopaedic management and made conclusions as to their validity. First, Dr. Kocher took on the myth of prophylactic pinning on the contralateral "normal" side for a patient with a slipped capital femoral epiphysis. Second, Dr. Probe evaluated the myth that all intertrochanteric fractures are best treated with intramedullary devices. Last, Dr. Foster and Dr. Silvestri tackled the myth that autograft is always the best choice for anterior cruciate ligament (ACL) reconstruction. All three of these topics are subjects of current debate. The panel's careful examination of the available data along with their expertise in the management of these problems is presented in this thought-provoking JBJS Critical Issues article.

Abstract
BACKGROUND The reported prevalence of radiological osteoarthritis (OA) after anterior cruciate ligament (ACL) reconstruction varies from 10% to 90%. Purpose/ HYPOTHESIS To report the prevalence of OA after ACL reconstruction and to compare the OA prevalence between quadrupled semitendinosus tendon (ST) and bone-patellar tendon-bone (BPTB) grafts. The hypothesis was that there would be no difference in OA prevalence between the graft types. The secondary aim was to study whether patient characteristics and additional injuries were associated with long-term outcomes. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS Radiological examination results, Tegner activity levels, and Knee injury and Osteoarthritis Outcome Score (KOOS) values were determined in 135 (82%) of 164 patients at a mean of 14 years after ACL reconstruction randomized to an ST or a BPTB graft. Osteoarthritis was defined according to a consensus by at least 2 of 3 radiologists of Kellgren-Lawrence grade ≥2. Using regression analysis, graft type, sex, age, overweight, time between injury and reconstruction, additional meniscus injury, and a number of other variables were assessed as risk factors for OA 14 years after ACL reconstruction. RESULTS Osteoarthritis of the medial compartment was most frequent, with 57% of OA cases in the ACL-reconstructed knee and 18% of OA cases in the contralateral knee (P < .001). There was no difference between the graft types: 49% of OA of the medial compartment for BPTB grafts and 65% for ST grafts (P = .073). The KOOS results were lower for patients with OA in all subscales, indicating that OA was symptomatic. No difference in the KOOS between the graft types was found. Meniscus resection was a strong risk factor for OA of the medial compartment (odds ratio, 3.6; 95% CI, 1.4-9.3) in the multivariable logistic regression analysis. CONCLUSION A 3-fold increased prevalence of OA was found after an ACL injury treated with reconstruction compared with the contralateral healthy knee. No differences in the prevalence of OA between the BPTB and quadrupled ST reconstructions were found. An initial meniscus resection was a strong risk factor for OA; the time between injury and reconstruction was not.

Abstract
BACKGROUND Clinical outcomes of autograft and allograft anterior cruciate ligament (ACL) reconstructions are mixed, with some reports of excellent to good outcomes and other reports of early graft failure or significant donor site morbidity. OBJECTIVE To determine if there is a difference in functional outcomes, failure rates, and stability between autograft and allograft ACL reconstructions. DATA SOURCES Medline, Cochrane Central Register of Controlled Trials (Evidence Based Medicine Reviews Collection), Cochrane Database of Systematic Reviews, Web of Science, CINAHL, and SPORTDiscus were searched for articles on ACL reconstruction. Abstracts from annual meetings of the American Academy of Orthopaedic Surgeons, American Orthopaedic Society for Sports Medicine, and Arthroscopy Association of North America were searched for relevant studies. STUDY SELECTION INCLUSION CRITERIA FOR STUDIES WERE AS FOLLOWS: primary unilateral ACL injuries, mean patient age less than 41 years, and follow-up for at least 24 months postreconstruction. Exclusion criteria for studies included the following: skeletally immature patients, multiligament injuries, and publication dates before 1990. DATA EXTRACTION Joint stability measures included Lachman test, pivot-shift test, KT-1000 arthrometer assessment, and frequency of graft failures. Functional outcome measures included Tegner activity scores, Cincinnati knee scores, Lysholm scores, and IKDC (International Knee Documentation Committee) total scores. RESULTS More than 5000 studies were identified. After full text review of 576 studies, 56 were included, of which only 1 directly compared autograft and allograft reconstruction. Allograft ACL reconstructions were more lax when assessed by the KT-1000 arthrometer. For all other outcome measures, there was no statistically significant difference between autograft and allograft ACL reconstruction. For all outcome measures, there was strong evidence of statistical heterogeneity between studies. The sample size necessary for a randomized clinical trial to detect a difference between autograft and allograft reconstruction varied, depending on the outcome. CONCLUSIONS With the current literature, only KT-1000 arthrometer assessment demonstrated more laxity with allograft reconstruction. A randomized clinical trial directly comparing allograft to autograft ACL reconstruction is warranted, but a multicenter study would be required to obtain an adequate sample size.

Abstract
BACKGROUND There has been growing interest in anatomical reconstruction of the anterior cruciate ligament (ACL), including the use of double-bundle (DB) reconstruction techniques. HYPOTHESIS The DB technique will not be cost-effective when compared with single-bundle (SB) reconstruction. STUDY DESIGN Economic and decision analysis; Level of evidence, 1. METHODS A decision-analysis model with input values derived from the literature was used to estimate the cost-effectiveness of DB ACL reconstruction compared with SB ACL reconstruction. Effectiveness was based on the revision rate and the postoperative International Knee Documentation Committee (IKDC) score. RESULTS Sixty-four percent of DB knees result in an IKDC score of A, compared with 54% of SB knees. The incremental cost-effectiveness ratio of a DB reconstruction compared with an SB reconstruction was $6416 per quality adjusted life year in the baseline scenario and $64 371 per quality adjusted life year in the alternate scenario. The model is very sensitive to the proportions of IKDC A outcomes. The model is also sensitive to the utility values assigned to IKDC A and B outcomes and is less sensitive to the marginal cost of a DB reconstruction. CONCLUSION This preliminary analysis based on published clinical results to date shows DB ACL reconstruction may be cost-effective, despite increased upfront cost. More research is needed to confirm whether there is any difference in the distribution of IKDC outcomes between the 2 techniques. Perhaps more importantly, the lack of any other demonstrated clinical benefit from the DB technique questions the clinical relevance of this difference in IKDC scores. CLINICAL RELEVANCE Revision data and longer term outcomes after DB reconstruction and more reliable clinical utility data are needed to definitively compare the cost-effectiveness of DB and SB ACL reconstruction. Studies of ACL reconstruction and other sports medicine procedures should report the distribution of outcomes data to facilitate future analyses of clinical effectiveness.

Abstract
BACKGROUND Randomized controlled trials after anterior cruciate ligament reconstructions with long-term follow-up including assessment of health-related quality of life are rare. PURPOSE To compare clinical outcome and health-related quality of life 8 years after anterior cruciate ligament reconstruction using 2 types of graft. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS Long-term follow-up of 164 patients with anterior cruciate ligament injury randomized to arthroscopic reconstruction with a quadrupled semitendinosus graft or a bone-patellar tendon-bone graft was undertaken. After a mean 8 years, 153 patients were available for follow-up, including instrumented laxity, 1-legged hop test, a knee-walking test, and assessment with International Knee Documentation Committee, Lysholm, Tegner, and patellofemoral pain score. Health-related quality of life was assessed with Knee Osteoarthritis Outcome Score and Short Form-36. RESULTS Patients in both graft groups retained the same stability, knee function, and health-related quality of life. The patellofemoral pain score was similar for both groups; the bone-patellar tendon-bone group had more donor site morbidity from kneeling and knee walking. In the bone-patellar tendon-bone group, 19 patients had no kneeling problems, 23 slight problems, 31 moderate problems, and 5 unable to kneel. Corresponding figures for the semitendinosus group were 25, 32, 16, and 2 (P < .001). Patients with early reconstructions (<5 months) had a lower risk for meniscal injuries (37%) than did later reconstructed (62%, P = .008). Health-related quality of life regarding physical functioning in Short Form-36 was better for the early-reconstructed patients than for the later reconstructed (92 vs 85; P = .014). Patients without medial meniscal surgery had higher Knee Osteoarthritis Outcome Scores for all subscales than did patients with medial meniscal surgery, with most significant difference for sport and recreation (63 vs 75, P = .008). CONCLUSION In the long term, the semitendinosus graft provided similar stability, knee function, and health-related quality of life but with less kneeling morbidity than did the bone-patellar tendon-bone graft.

Abstract
BACKGROUND A more horizontal femoral tunnel has been emphasized for contemporary anterior cruciate ligament (ACL) reconstruction. However, lowering the femoral tunnel may result in a shorter tunnel. In addition, a more horizontally placed femoral tunnel may have inadequate bone stock at the posterior portion of the tunnel, which can lead to protrusion of the cross-pin (Rigidfix) system for femoral fixation. HYPOTHESIS A more horizontal femoral tunnel position, particularly via the anteromedial (AM) portal technique, will reduce femoral tunnel length, and a more horizontal femoral tunnel position and anterior-to-posterior pin insertion will increase the risk of Rigidfix pin protrusion. STUDY DESIGN Controlled laboratory study. METHODS In 10 cadaveric knees, we measured maximum lengths of the femoral tunnels at the positions of 11:30, 10:30, and 9:30 o'clock using the transtibial technique and at the 10:30 and 9:30 o'clock using the AM portal technique. Then, for each femoral tunnel via the transtibial technique at 11:30, 10:30, and 9:30 o'clock positions, tests were performed for 3 directions of Rigidfix pin insertion using the lateral epicondyle as an anatomical landmark, namely, 15 degrees anterior to posterior (A-P), neutral, and 15 degrees posterior to anterior (P-A). It was then determined whether pins protruded from the posterior cortex. RESULTS The lengths of femoral tunnels produced using the transtibial technique became shorter as the femoral starting position became more horizontal (51.1 mm, 40.0 mm, and 34.2 mm on average at the 11:30, 10:30, and 9:30 o'clock position, respectively). Tunnels made using the AM portal technique were significantly shorter than those made using the transtibial technique: by 7.6 mm at the 10:30 o'clock and 4.5 mm at the 9:30 o'clock positions on average (P < .001). In addition, increasing obliquity increased the likelihood of Rigidfix pin protrusion, especially when pins were inserted in the A-P direction. CONCLUSION The current effort to lower the femoral tunnel position in ACL reconstruction can shorten the tunnel length and compromise the graft fixation at the femur using the Rigidfix system. CLINICAL RELEVANCE When an intended femoral tunnel position is more horizontal than the 10:30 o'clock position for ACL reconstruction, a surgeon needs to be cautious regarding a short femoral tunnel, particularly when using the AM portal technique, and possible protrusion of the cross-pin (Rigidfix) fixator.

Abstract
BACKGROUND Despite the large number of anterior cruciate ligament reconstructions performed each year, there remains a significant controversy regarding the effect of the graft source on the functional outcome of patients. HYPOTHESIS There is no difference in outcomes of autograft versus allograft anterior cruciate ligament reconstructions. STUDY DESIGN Systematic review. METHODS The authors systematically identified prospective studies (Oxford level of evidence I or II only) that included autograft patients, allograft patients, or both. Objective outcomes that were reported were meta-analyzed; this included pivot-shift results, KT-1000 arthrometer results, International Knee Documentation Committee (IKDC) scores, Lysholm Scores, graft failures, and postoperative complications. Two statistical analyses were performed. First a primary statistical analysis was performed comparing pooled autograft data (bone-patellar-tendon bone and hamstrings combined) and pooled allograft data (bone-patellar-tendon bone and hamstrings combined). To have a more comprehensive understanding of the differences between each specific graft source, a secondary analysis was performed without pooling the data; this directly compared the 4 types of graft sources that were studied. RESULTS Over 400 scientific manuscripts were initially reviewed; 31 manuscripts fulfilled all of the search criteria. There were very few statistically significant differences between autograft and allograft tissue. The KT-1000 arthrometer laxity testing revealed a mean of 1.4 +/- 0.2 mm (weighted mean +/- standard error of the mean) for the allograft group compared with 1.8 +/- 0.1 mm for the autograft group (t = 2.40; P <.02). However, this difference was only for the mean score; there was no statistical significance when considering KT-1000 arthrometer measurements of greater than 3 or 5 mm. The percentage of patients receiving a final IKDC score of "A" (normal knee) was statistically significant for allograft tissue (43.9% +/- 5.5%) versus autograft tissue (28.2% +/- 1.0%) reconstructions. There was no statistically significant difference between the percentages of IKDC scores of A or B for patients receiving pooled allograft (82.9% +/- 4.2%) versus pooled autograft (87.2% +/- 0.9%) anterior cruciate ligament reconstruction (t = 1.01; P > .1). The graft failure rate was 4.7 +/- 0.5 per 100 for autograft reconstructions and 8.2 +/- 2.1 per 100 allograft reconstructions; although this may represent a trend, it is not statistically significant (t = 1.49; P > .1). The complication rate was slightly higher for autograft reconstructions at 3.5 +/- 0.4 complications per 100 autograft reconstructions compared with 2.4 +/- 1.1 complications per 100 allograft reconstructions, but not significant (t = 1.41; P > .1). CONCLUSION After a comprehensive examination and statistical analysis of the modern literature, the authors could not identify an individual graft source that was clearly superior to the other graft sources. This led them to believe that, with currently available data, the graft source has a minimal effect on the outcome of patients undergoing anterior cruciate ligament reconstruction.

Abstract
BACKGROUND There is increasing interest in comparing the efficacy of single-bundle versus double-bundle anterior cruciate ligament reconstruction. Challenging this comparison, however, has been the lack of an established consensus on the success of single-bundle reconstruction. HYPOTHESIS The current outcomes of single-bundle reconstruction can be clarified from a large unbiased body of evidence for future comparisons with double-bundle reconstructions. STUDY DESIGN Systematic review. METHODS A systematic review of 11 randomized, controlled trials comparing patellar tendon and hamstring tendon grafting is reported. The respective outcomes of each group were combined to assist the orthopaedic surgeon in assessing the current success of single-bundle reconstruction. The primary factors assessed were tibial subluxation and side-to-side differences in laxity. Secondary outcomes included concomitant injuries and treatments, complications, graft failure, range of motion, and radiographic evidence of degenerative changes. RESULTS In this review of 1024 single-bundle anterior cruciate ligament reconstructions, 495 concomitant meniscal tears, 95 chondral injuries, and 2 posterior cruciate ligament tears were noted. The complication rate was 6%, and graft failure 4%. Reported pivot-shift test results were negative in 81% of cases; reported Lachman tests were negative in 59% cases; and KT-1000 arthrometer side-to-side differences were <or= 5 mm in 86% of cases. Flexion and extension deficits were reported in 9 of 11 studies through mean range of motion or deficit ranges. Radiographic changes of articular surface abnormalities were observed in 7% of the knees at follow-up investigation. CONCLUSION Systematic review of a significant body of unbiased outcome data on single-bundle anterior cruciate ligament reconstruction demonstrates it to be a safe, consistent surgical procedure affording reliable results. CLINICAL RELEVANCE These results may be used to assist orthopaedic surgeons in evaluating the benefit and practicality of pursuing new anterior cruciate ligament reconstruction techniques over standard single-bundle anterior cruciate ligament reconstruction.

Abstract
There is a lack of knowledge regarding predictive factors for a successful clinical outcome after an anterior cruciate ligament (ACL) reconstruction. The aim was to investigate pre-operative factors that may predict good outcomes as measured with the subscales Function in sports and recreation and Quality of life in Knee injury Osteoarthrithis Outcome Score (QOL-KOOS), one-leg hop test and Tegner Activity Scale 12 months after ACL reconstruction. Sixty-four patients, operated with either patellar or hamstring tendon graft, were included. Demographics, range of motion, anterior knee laxity, pivot shift, muscle-torques, anterior knee pain (AKP) and knee function were registered pre-operatively and used in a multiple regression model. Results show less degree of AKP and low influence on knee function to be the most important predictors for good outcome in Sport/Rec-KOOS (explained 31% of variances). Less AKP was in addition the most important predictor for QOL-KOOS (14%). Patellar-tendon graft, in favor of hamstring tendon graft, explained 8% of the improvement in the Tegner Activity Scale. In conclusion, a low degree of AKP was found to be the most important predictor for good clinical outcome 12 months after ACL reconstruction. Future studies, including psychological parameters, should use analyses that have the potential to control for independency between variables.

Abstract
From individual randomized studies, it is unclear whether patellar tendon grafts or hamstring tendon grafts yield the best functional results after ACL reconstruction. Therefore, we performed a meta-analysis to provide quantitative data to compare patellar with hamstring grafts after ACL reconstruction with regard to knee function. We searched computerized databases for randomized controlled trials reporting one of the following outcomes related to function: final overall International Knee Documentation Committee score and return to preinjury level of activity. Studies were abstracted independently by two reviewers. Random effect models were used to pool the data. Fourteen trials (1263 patients) met the inclusion criteria. We found no difference in final overall International Knee Documentation Committee score or in the number of patients returning to full activity after patellar and hamstring graft reconstruction. Relative risk was 0.90 for final overall International Knee Documentation Committee Class A and 0.94 for return to preinjury level of activity in favor of patellar grafts. Quantitative interaction tests on the effect of treatment based on study quality, randomization status, number of strands used, and length of followup were non significant. At last followup, only 41% and 33% of patients, respectively, had patellar and hamstring grafts reconstructed reported as normal based on the final overall International Knee Documentation Committee score.

Abstract
PURPOSE Self-reported outcomes after primary ACL reconstruction using allograft tissues were compared at > or = 5 yr (group 1) and at 2-4 yr (group 2) after surgery. METHODS The IKDC Subjective Knee Evaluation and Current Health Assessment and the Knee Outcome Survey Activities of Daily Living Scale (KOS-ADLS) and the Sports Activity Scale (KOS-SAS) were mailed to 335 consecutive former patients at > or = 2 yr after surgery. RESULTS Surveys were completed and returned by 64.6% of former patients. Time after surgery for group 1 (N = 90) and group 2 (N = 116) was 7.8 +/- 2.7 and 2.8 +/- 0.8 yr, respectively. Groups did not differ for IKDC Subjective Knee Evaluation or KOS-ADLS scores, although group 1 displayed a lower mean KOS-SAS score. Pooled IKDC Subjective Knee Evaluation scores were 42.7% normal (A), 22.8% nearly normal (B), 24.8% abnormal (C), or 9.7% severely abnormal (D). Pooled standardized IKDC Subjective Knee Evaluation z scores were -0.80 +/- 1.4 standard deviations below the reported population mean for unimpaired individuals with 33.5% scoring at or above the normative population mean, 28.2% scoring < 1 standard deviation below the normative population mean, 18.8% scoring between 1 and 2 standard deviations below the normative population mean, and 19% scoring > or = 2 standard deviations below the normative population mean. Pooled KOS-ADLS scores were 62.1% (> or = 90%), 18% (89-80%), 10.2% (79-70%), and 9.7% (< 70%). Pooled KOS-SAS scores were 49.5% (102/206, > or = 90%), 25.7% (53/206, 89-80%), 9.7% (20/206, 79-70%), and 15.1% (31/206, < 70%). Groups displayed comparable knee function before injury and at the time of the survey. Pooled knee-function scores decreased from 9.5 +/- 1.6 before injury to 8 +/- 2.5 current function (84% return). Both groups displayed decreases in current sports activity level from strenuous to moderate and frequency from 4-7 to 1-3 times per week. CONCLUSIONS Self-reported outcomes did not differ between groups for the IKDC Subjective Knee Evaluation or for the KOS-ADLS score, although group 1 displayed decreased mean KOS-SAS scores, suggesting decreased perceived sporting activity knee function at > or = 5 yr after surgery. Decreased sports activity level and frequency are comparable with self-reported outcome studies after primary ACL reconstruction using autograft tissues.

Abstract
INTRODUCTION Problems with the initial fixation strength and widening of the femoral and tibial canal after ACL reconstruction using a triple or quadruple semitendinosus autograft have led to the introduction of the so-called Hybrid fixation with the additional use of interference screws. Pain and intraarticular migration have been reported with metal interference screws requiring implant removal (Am J Knee Surg 11:32-34, 2000, Arthroscopy 11:289-291, 1995) but not yet with bioabsorbable screws. MATERIALS AND METHODS We report on two cases were the intraarticular position of a bioabsorbable interference screw possibly due to migration in the early postoperative period lead to symptoms, the need for further surgery, and implant removal. RESULTS A preoperative MRI revealed the diagnosis. After removal of the tibial interference screw both knees were settling down, albeit with residual instability and only a moderate clinical result. DISCUSSION Despite the attractiveness of bioabsorbable screws due to the very fact that they are being reabsorbed over time, there is a slight risk of migration in the first month after the operation. In any suspicious case an MRI will easily clarify the diagnosis.

Abstract
The purpose of this study is to evaluate the mechanical properties of a graft fixation using a small diameter soft tissue interference screw and analyze the factors affecting the fixation strength. Forty porcine knees were used. A bone tunnel, either 4.5 mm (n=40) or 5.0 mm (n=40) in diameter, was created in the bone block obtained from the proximal tibia or the distal femur. A patella-patellar tendon specimen with varied width was harvested, and the distal end of the patellar tendon was fixed within the bone tunnel using a small diameter soft tissue interference screw (4 x 15 mm). Then, the patella-patellar tendon-bone block complex was loaded until failure occurred and the maximum load was measured. As potential influential factors on the fixation strength, the insertion torque, bone mineral density of the bone block, and graft/tunnel cross-sectional area ratio (GTR) of each specimen were calculated. A significant correlation between the maximum failure load and the insertion torque was demonstrated. The quadratic regression analysis showed a statistically significant correlation between the failure load and the GTR. Optimal GTR for achieving high fixation strength was approximately 80%. When used in appropriate conditions, the mean failure load was 177 N for the 4.5 mm screw and 180 N for the 5 mm screw. The use of a small diameter interference screw for the fixation of a tendon graft to a bone is clinically feasible. Our research showed that the selection of appropriate fitting conditions is an important factor for optimizing the properties of the fixation.

Abstract
OBJECTIVES To analyze ligamentous stability and isokinetic strength of knee extensor and flexor muscles after anterior cruciate ligament reconstruction using 2 different autografts with identical fixation. DESIGN This study implements a comparative case series design. SETTING Schulthess Clinic, Switzerland. PATIENTS A total of 153 consecutive patients (n = 87 bone-patellar tendon-bone [BPTB]/66 quadruple semitendinosus/gracilis tendons [QSGT] patients) who underwent BPTB and QSGT surgery were functionally assessed. INTERVENTION All patients were functionally assessed (knee extension/flexion isokinetic strength and knee joint laxity) at a mean follow-up time of 11 months. MAIN OUTCOME MEASUREMENTS Laxity was measured utilizing the Kneelax arthrometer, whereas isokinetic strength of the knee extensor/flexor muscle groups was measured using the Biodex Multi Joint System 2 (180 degrees/s and 300 degrees/s). RESULTS The QSGT group had significantly greater knee joint laxity when compared with the BPTB group (P < 0.001). Furthermore, females in the QSGT group demonstrated the greatest knee joint laxity overall (P < 0.001). Additionally, a significant flexor torque deficiency was demonstrated in the QSGT group (P < 0.001); however, no differences in extensor torque were observed. CONCLUSIONS The use of a BPTB autograft achieved better knee joint stability as well as greater knee flexor torque than the QSGT autograft. Both grafts exhibited a similar knee extensor torque deficit, indicating that only quadriceps strength is not graft-dependent.

Abstract
Forty-three patients who had undergone an anterior cruciate ligament (ACL) reconstruction using a doubled semitendinosus and gracilis graft were prospectively reviewed at 5-year follow-up. All had suffered subacute or chronic tears of the ligament. At surgery, the femoral tunnel was drilled first through the antero-medial portal. The correct position of the femoral and tibial guide wire was checked fluoroscopically. A cortical fixation to the bone was achieved in the femur with a Mitek anchor, directly passing the two tendons in the slot of the anchor, and in the tibia with an RCI screw, supplemented with a spiked washer and bicortical screw. Rehabilitation was aggressive, controlled and without braces. The International Knee Documentation Committee (IKDC) form, KT-1000 arthrometer, and Cybex dynamometer were employed for clinical evaluation. A radiographic study was also performed. At the 5-year follow-up all the patients had recovered full range of motion and 2% of them complained of pain during light sports activities. Four patients (9.5%) reported giving-way symptoms. The KT-1000 side-to-side difference was on average 2.1 mm at 30 lb, and 68% of the knees were within 2 mm. The final IKDC score showed 90% satisfactory results. There was no difference between the 2-year and 5-year evaluations in terms of stability. Extensor and flexor muscle strength recovery was almost complete (maximum deficit 5%). Radiographic study showed a tunnel widening in 32% of the femurs and 40% of the tibias. A correlation was found between the incidence of tibial tunnel widening and the distance of the RCI screw from the joint (the closer the screw to the joint, the lower the incidence of widening). In conclusion, we can state that, using a four-strand hamstring graft and a cortical fixation at both ends, we were able to achieve satisfactory 5-year results in 90% of the patients.

Abstract
BACKGROUND Although there is evidence that very active, young patients are better served with anterior cruciate ligament reconstruction, there is a lack of objective data demonstrating that future knee injury is prevented by these procedures. HYPOTHESIS Anterior cruciate ligament reconstruction protects against reinjury of the knee that would require reoperation. STUDY DESIGN Retrospective cohort study. METHODS A cohort of 6576 active-duty army personnel who had been hospitalized for anterior cruciate ligament injury from 1990 to 1996 were identified. Using the Total Army Injury and Health Outcomes Database, the authors followed these individuals for up to 9 years and collected clinical, demographic, and occupational data. These data were evaluated with bivariate and multivariable analyses to determine the effect of anterior cruciate ligament reconstruction on the rate of knee reinjury that required operation. RESULTS Of the 6576 study subjects, 3795 subjects (58%) underwent anterior cruciate ligament reconstruction and 2781 (42%) did not. The rate of reoperation was significantly lower among the anterior cruciate ligament reconstruction group (4.90/100 person-years) compared with those treated conservatively (13.86/100 person-years; P < .0001). Proportional hazard regression analyses adjusted for age, race, sex, marital status, education, and physical activity level confirmed that anterior cruciate ligament reconstruction was protective against meniscal and cartilage reinjury (P < .0001). Secondary medial meniscal injury was more common than secondary lateral meniscal injury (P < .003). Younger age was the strongest predictor of failure of conservative management leading to late anterior cruciate ligament reconstruction (P < .0001). CONCLUSIONS Anterior cruciate ligament reconstruction protected against reoperation in this young, active population; younger subjects were more likely to require late anterior cruciate ligament reconstruction. CLINICAL RELEVANCE Strong consideration should be given to anterior cruciate ligament reconstruction after anterior cruciate ligament injury in young, active individuals.

Abstract
Anterior cruciate ligament graft choice is controversial, with no evidence-based consensus available to guide decision making. The study design was evidence-based medicine systematic review of randomized controlled trials evaluating patellar tendon versus hamstring tendon autografts. A literature review identified 9 randomized controlled trials comparing patellar tendon and hamstring tendon autografts. An evidence-based systematic review was performed. Objective and subjective outcomes of interest included surgical technique, rehabilitation, instrumented laxity, isokinetic strength, patellofemoral pain, return to preinjury activity, and Tegner, Lysholm, Cincinnati, and International Knee Documentation Committee-1991 scores. Additional surgery, graft failure, and complications were reviewed. Slight increased laxity on arthrometer testing was seen in the hamstring population in 3 of 7 studies. Pain with kneeling was greater for the patellar tendon population in 4 of 4 studies. Only 1 of 9 studies showed increased anterior knee pain in the patellar tendon group. Frequency of additional surgery seemed to be related to the fixation method and not graft type. No study reported a significant difference in graft failure between patellar tendon and hamstring tendon autografts. Objective differences (range of motion, isokinetic strength, arthrometer testing) were not detected between groups in the majority of studies, suggesting that their sensitivity to detect clinical outcomes may be limited. Increased kneeling pain in the patellar tendon group was seen consistently in the studies evaluated. Subjective differences in anterior knee pain or return-to-activity level were not consistently observed in these studies. With numbers available, failure rates were not significantly different between groups. These findings suggest that graft type may not be the primary determinant for successful outcomes after anterior cruciate ligament surgery.

Abstract
Several graft options exist for reconstruction of the deficient ACL. The most commonly used grafts are the BPTB and quadrupled hamstring tendon autografts. Based on a comprehensive review of the literature, one graft is not superior to the other. Advantages and disadvantages are associated with the use of each graft. Surgeons who perform ACL reconstruction should be familiar with the use of both grafts.
