Background: Stacked screws is a commonly used technique in single-stage revision anterior cruciate ligament (ACL) reconstruction in the setting of bone loss, but there are limited data to support its use. Hypothesis: Two configurations of a biocomposite stacked screws construct have similar fixation strength and linear stiffness as a primary ACL reconstruction construct in a biomechanical model. Study Design: Controlled laboratory study. Methods: A total of 30 porcine legs were divided into 3 groups. Group 1 underwent primary ACL reconstruction with a patellar tendon graft fixed into the femur, with an 8-mm biocomposite interference screw of beta-tricalcium phosphate and poly lactide-co-glycolide. For a revision ACL reconstruction model, groups 2 and 3 had bone tunnels created and subsequently filled with 12-mm biocomposite screws. New bone tunnels were drilled through the filler screw and the surrounding bone, and the patellar bone plug was inserted. Group 2 was fixed with 8-mm biocomposite screws on the side of the graft opposite the filler screw, while group 3 had the interference screw interposed between the graft and the filler screw. The construct was loaded at 1.5 mm/s in line with the tunnel until failure. Load to failure, linear stiffness, and mode of failure were recorded. Results: The mean pullout strength for groups 1, 2, and 3 was 626 ± 145 N, 653 ± 152 N, and 720 ± 125 N, respectively ( P = .328). The mean linear stiffness of the construct in groups 1, 2, and 3 was 71.4 ± 9.9 N/mm, 84.1 ± 11.1 N/mm, and 82.0 ± 10.8 N/mm, respectively. Group 2 was significantly stiffer than group 1 ( P = .037). Conclusion: Two configurations of a biocomposite stacked screws construct for a single-stage revision ACL reconstruction in the setting of bone loss show a similar fixation strength and linear stiffness to a primary ACL reconstruction at time zero in a porcine model. Clinical Relevance: In the setting of bone loss from tunnel malpositioning, a single-stage revision ACL reconstruction using a stacked screws construct may provide adequate fixation strength and linear stiffness.

Primary Acl Reconstruction

Background: PROMIS (Patient-Reported Outcomes Measurement Information System) scores in patients undergoing anterior cruciate ligament (ACL) reconstruction have not been fully described in the literature to date. The ability of preoperative patient-reported outcome scores to directly predict postoperative outcomes in patients who undergo primary ACL reconstruction is unknown. Hypothesis: Postoperative PROMIS physical function (PF), pain interference (PI), and depression (D) scores in patients who undergo ACL reconstruction will show improvement when compared with preoperative scores. Additionally, preoperative PROMIS PF, PI, and D scores will predict which patients will not achieve a minimal clinically important difference (MCID) postoperatively. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 233 patients who underwent primary ACL reconstruction between 2015 and 2016 and had completed PROMIS measures both preoperatively (within 60 days of surgery) and postoperatively (100-240 days after surgery) were included in this study. PROMIS PF, PI, and D scores were compared. Accuracy analyses were performed to determine whether preoperative PROMIS scores from each domain could predict postoperative achievement of MCID in the same domain. Cutoff scores were then calculated. Results: PROMIS PF, PI, and D scores all showed a significant improvement after ACL reconstruction (all P < .001). Preoperative scores from all 3 PROMIS domains showed a strong ability to predict clinically meaningful improvement, as defined by MCID, with areas under the receiver operating characteristic curve from 0.72 to 0.84. Optimal cutoffs for preoperative PROMIS scores showed that patients with a PF score of <42.5, PI score of >56.2, or D score of >44.8 were more likely to achieve MCID. Conclusion: PROMIS PF, PI, and D scores improved significantly in patients who underwent primary ACL reconstruction. Preoperative PROMIS PF, PI, and D scores were highly predictive of outcome in the early postoperative period. The reported cutoff scores showed high probability in predicting which patients would and would not achieve a clinically meaningful improvement.

Background: Several strategies have been studied to decrease the rate of infection after hamstring autograft anterior cruciate ligament (ACL) reconstruction. Our group started presoaking grafts with Vancomycin in November 2015 to decrease this risk. Purpose: The objective of the study is to compare the success of this protocol against the immediate previous period in which we did not use the protocol. Study design: Retrospective cohort. Level III. Methods: Consecutive periods were studied: April 2013-October 2015 (pre Vancomycin protocol) and November 2015- May 2018 (Vancomycin protocol). All patients that underwent a hamstring autograft primary ACL reconstruction during the periods studied were included. The final outcome was the presence of postoperative septic arthritis in both groups. Diagnosis of septic arthritis was made using the clinical picture plus cytological analysis of a joint aspiration (cell count > 50.000/uL + > 90% neutrophils) Statistical analysis was made using the Fisher’s exact test. Significance was set in p < 0.05. Results: 490 patients were included in the study, 230 in the pre Vancomycin protocol an 260 in the Vancomycin protocol. 4 postoperative septic arthritis were noted in the pre Vancomycin protocol (1.7%) while no septic arthritis was noted in the post Vancomycin protocol patients during the period studied. (p < 0.05) The 4 postoperative infections were presented at an average 21.7 days (range 16-25). Staphylococcus epidermidis was isolated in 2 of the cases, and in the other 2 no organism was isolated. Conclusion: Vancomycin presoaking of hamstring autografts in primary ACL reconstruction eliminated the risk of postoperative septic arthritis during the studied period compared to the immediate previous period, where no Vancomycin presoaking was used.

Background: High psychological readiness is an important element for returning to sports after anterior cruciate ligament (ACL) reconstruction. Identifying factors that contribute to psychological readiness is essential for planning interventions to return to play. No studies have used multivariate analysis to clarify factors associated with psychological readiness to return to specific sports. Hypothesis: To identify factors that contribute to an athlete’s psychological readiness to return after ACL reconstruction to sports that require cutting, pivoting, and jump-landings. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Study participants were athletes who before injury had participated in sports with limited contact that required cutting, pivoting, and jump-landings (basketball, soccer, futsal, volleyball, badminton, tennis, and frisbee) and hoped to return to the same sport after reconstruction. Psychological readiness was measured using the Anterior Cruciate Ligament–Return to Sport After Injury Scale (ACL-RSI) in athletes more than 6 months after primary ACL reconstruction. To clarify factors associated with the ACL-RSI, univariate regression analysis and multivariate regression analysis were performed using the following independent variables: age, sex, body mass index, time from injury to reconstruction, time from reconstruction to testing, meniscal surgery, modified Tegner activity scale before injury, kinesiophobia, limb symmetry index of knee strength, limb symmetry indices of single-leg hop (SLH) distances, and subjective running ability. Results: Higher subjective running ability, a lower kinesiophobia score, and greater limb symmetry in the lateral SLH were positively associated with psychological readiness. Conclusion: The psychological readiness of athletes aiming to return after ACL reconstruction to limited-contact sports that require cutting, pivoting, and jump-landings was affected by subjective running ability, kinesiophobia, and asymmetry of lateral SLH distance. This information may be useful in planning appropriate interventions and thereby increasing the likelihood of an athlete’s returning to such sports.

Background: One of the goals of anterior cruciate ligament (ACL) reconstruction is a meniscal protective effect on the knee. Despite the advancement of ACL reconstruction techniques, subsequent meniscal tears after ACL reconstruction remain a problem, and the risk factors for recurring lesions are still unclear. Purpose: To investigate the incidence of subsequent meniscal surgery after primary ACL reconstruction without revision ACL surgery and to determine the risk factors associated with this reoperation. Study Design: Case series; Level of evidence, 4. Methods: Overall, 518 patients who underwent primary ACL reconstruction between 2004 and 2012 at one instution participated in this study. Data on body mass index, graft type and femoral tunnel-drilling technique of ACL reconstruction, and location and type of meniscal injury and its treatment at ACL reconstruction were collected from medical records. Clinical outcomes were investigated, including side-to-side difference of anterior laxity, pivot-shift grade, and subsequent meniscal surgery without ACL insufficiency (at minimum 2-year follow-up). Results: The prevalence of tears to the medial meniscus (MM) at the primary ACL reconstruction was 43.6% (226/518), 140 of which were repaired; on the contrary, tears of the lateral meniscus (LM) had a prevalence of 55.8% (289/518), 42 of which were repaired. At a mean 30.3 months (range, 8-124 months) after ACL reconstruction, 20 patients (3.9%; 14 MM tears, 3 LM tears, 3 MM + LM tears) required meniscal surgery without ACL reinjury or recurrence of instability. Of these, 14 MMs and 3 LMs had been repaired at primary ACL reconstruction. The failure rates of repaired MM and LM were 10.0% (14/140) and 7.1% (3/42), respectively. The failure rate of MM repair using the all-inside technique (6/36) was significantly higher compared with no treatment, inside-out repair, or partial resection ( P = .045). In multiple regression analysis, the presence of MM injury at the time of ACL reconstruction (odds ratio [OR], 7.81; P = .003), the side-to-side difference of postoperative anterior tibial translation (OR, 1.91; P = .032), and follow-up period after ACL reconstruction (OR, 1.02; P = .003) were risk factors of subsequent meniscal surgery after ACL reconstruction. Conclusion: Incidence of subsequent meniscal surgery after successful ACL reconstruction was <5%. Presence of MM tear at the time of ACL reconsturuction, small amount of increased anterior laxity, and long-term period after ACL reconstruction were predictive of subsequent meniscal surgery.

Introduction: The pattern of meniscus tear has significant impact onsubsequent rehabilitation and functional outcome as theyare usually associated with ACL injury.Knowledge about associated meniscus tear helps to identifypatients in the early post-traumatic phase.  Objectives: To study meniscus tear patterns and associationbetween different tear patterns of meniscus in ACLinjured subjects and to identify potential demographic andother associated risk factors.  Methodology: Routine arthroscopic findings database of 54 patientsoperated for primary ACL reconstruction from January 2017to December 2018 was used to study associated tear of meniscus. Based on arthroscopic evaluation, cases weregrouped into meniscus having no tear, minor tear and majortear. Major tear included complete radial tears, root tearsand unstable longitudinal tears including bucket-handletears.  Result: Totalarthroscopycasesinthestudydurationwere124.Ofthose,43% (n=54) underwent ACL reconstruction (ACLR) for tornACL. Among the patients who underwent ACLR, 58% had notear, 26%hadminortears, and16%hadmajortears ofthemeniscus. Therewere significant differencesbetweenthree groups for gender, age groupsandmechanism of injury. Risk factors formajortearsweremalegenderandage<30years.Minorandmajortears were associated with a contact injury.  Conclusion: Male, age <30 years and history of contact injury havehigh risks for having an associated meniscus tear. Earlyreferral to magnetic resonance imaging and/or arthroscopyis recommended to allow meniscus repair in a timelymanner.

ObjectiveTo describe the criteria used to clear athletes to return to sport (RTS) following primary ACL reconstruction.DesignScoping review.Data sourcesMEDLINE, Embase, CINAHL and SPORTDiscus electronic databases were searched using keywords related to ACL and RTS.Eligibility criteriaProspective or retrospective studies reporting at least one RTS criterion for athletes who had primary ACL reconstruction with an autograft.ResultsIn total, 209 studies fulfilled the inclusion criteria. RTS criteria were categorised into six domains: time, strength, hop testing, clinical examination, patient-report and performance-based criteria. From the 209 included studies, time was used in 178 studies (85%), and in 88 studies (42%) was the sole RTS criterion. Strength tests were reported in 86 studies (41%). Sixteen different hop tests were used in 31 studies (15%). Clinical examination was used in 54 studies (26%), patient report in 26 studies (12%) and performance-based criteria in 41 studies (20%).SummaryTime and impairment-based measures dominated RTS criteria, despite sport being a complex physical and biopsychosocial activity with demands across all aspects of function. Time was included as a criterion in 85% of studies, and over 80% of studies allowed RTS before 9 months. Whether RTS tests are valid—do they predict successful RTS?—is largely unknown.
