Significant Increase in the Rate of Meniscal and Chondral Injuries Between Primary and Revision Anterior Cruciate Ligament Reconstruction. (188)

Objectives: Anterior cruciate ligament (ACL) injuries are often associated with meniscal and chondral lesions. Meniscal lesions are present in up to 50% of ACL injured knees, and chondral lesions occur with an incidence of 20% to 40% in acute ACL-injured knees. The major importance of this lies in the fact that menisectomy and severe chondral damage are important predictors of poor outcomes including the subsequent development of knee osteoarthritis. Furthermore, patient reported outcomes following revision ACL reconstruction remain inferior to primary ACL reconstruction and this may, at least in part, be due to an increased incidence and severity of meniscal and chondral injuries. Although multiple studies have demonstrated that meniscal and chondral lesions are generally present at a higher rate at the time of revision ACL reconstruction when compared to primary ACL reconstruction, large studies following individual patients through primary and revision ACL reconstruction and tracking the change in the occurence of these injuries are scarce. The primary objective of this study was to determine the proportion of patients with meniscal and chondral injuries at the time of primary ACL reconstruction and determine how this rate changed by the time they underwent revision ACL reconstruction. The hypothesis was that the proportion of patients with meniscal and/or chondral lesions would be significantly greater at revision ACL reconstruction when compared to the primary procedures. Methods: Consecutive patients who underwent primary and then revision ACL reconstruction between March 1999 and February 2018 were identified using a single center registry. Patient characteristics, and intraoperative data from each procedure were collected and analyzed. This specifically included the occurrence and type of meniscal and chondral pathology. Descriptive statistics were used to evaluate the study sample using medians, descriptive data analysis was conducted depending on the nature of the criteria. Comparison between variables were assessed with student’s t test for quantitative variables and Mcnemar test for categorical variables. Statistical significance was set a t p<0.05. Results: 213 consecutive patients underwent both primary ACL reconstruction and then revision surgery during the study period. The average time from primary ACLR to Revision was 46.8 ± 36.6 months (range 5-181).The mean age of patients at primary ACLR was 22.21±7.21 years. The mean age of patients at revision ACLR 26.1 ± 8.3 years. The mean IKDC for the entire population was 85.53 ± 11.59, The mean ACL-RSI score was 71.89 ± 23.95. The mean Lysholm score was 91.77±10.24. The proportion of patients with chondral lesions significantly increased from 7% at primary ACL to 15.5% at revision ACL (p < 0.05). Meniscal lesions also significantly increased from 44.6 % at primary ACLR to 70% at revision ACLR (p < 0.05). There was no significant difference in the rate of lateral meniscal lesions (11.7 vs 13.1, p > 0.05). However, the proportion of patients with a medial meniscus lesion (25.4 vs 36.2, p < 0.05) and bimeniscal lesions (7.5 vs 20.7, p < 0.05) increased significantly at revision ACL reconstruction. Conclusions: The proportion of patients with meniscal and//or chondral injuries at the time of revision ACL reconstruction is significantly higher than at the time of primary ACL reconstruction. Specifically, the rate of medial meniscus and bimeniscal injuries is significantly higher in patients undergoing revision ACL reconstruction

Primary Acl Reconstruction

Context: Reconstruction of the anterior cruciate ligament (ACL) is one of the most common surgical procedures, with more than 200,000 ACL tears occurring annually. Although primary ACL reconstruction is a successful operation, success rates still range from 75% to 97%. Consequently, several thousand revision ACL reconstructions are performed annually and are unfortunately associated with inferior clinical outcomes when compared with primary reconstructions. Evidence Acquisition: Data were obtained from peer-reviewed literature through a search of the PubMed database (1988-2013) as well as from textbook chapters and surgical technique papers. Study Design: Clinical review. Level of Evidence: Level 4. Results: The clinical outcomes after revision ACL reconstruction are largely based on level IV case series. Much of the existing literature is heterogenous with regard to patient populations, primary and revision surgical techniques, concomitant ligamentous injuries, and additional procedures performed at the time of the revision, which limits generalizability. Nevertheless, there is a general consensus that the outcomes for revision ACL reconstruction are inferior to primary reconstruction. Conclusion: Excellent results can be achieved with regard to graft stability, return to play, and functional knee instability but are generally inferior to primary ACL reconstruction. A staged approach with autograft reconstruction is recommended in any circumstance in which a single-stage approach results in suboptimal graft selection, tunnel position, graft fixation, or biological milieu for tendon-bone healing. Strength-of-Recommendation Taxonomy (SORT): Good results may still be achieved with regard to graft stability, return to play, and functional knee instability, but results are generally inferior to primary ACL reconstruction: Level B.

Objectives: Anterior cruciate ligament (ACL) injury of the knee is commonly associated with meniscal and chondral lesions. This study was performed to assess the relative risk factors as well as the extent of the meniscal and chondral pathology at the time of arthroscopic ACL reconstruction. Materials and Methods: In this prospective study, patients undergoing ACL reconstruction were enrolled. Association of meniscal and chondral lesions was analyzed with age, sex, body mass index (BMI), mechanism of injury (sports-related or not), time gap between injury and surgery (<3 month and >3 months), and instability episodes. Logistic regression and Pearson Chi-square test were applied for evaluating the association. Results: A total of 55 patients (mean age 30 years [19–50 years]; 45 male:10 female) underwent arthroscopic ACL reconstruction, out of which 20 (36.3%) had isolated lateral meniscus tear, 14 (25.4%) had isolated medial meniscus tear, and 3 (5.4%) had both lateral and medial meniscus tear. BMI (P = 0.031) and instability episodes (P = 0.033) were predictor for meniscal lesions. Male sex was associated with significantly higher medial (P = 0.049) and lateral meniscal (P = 0.008) lesions. The older age group (>30 years) was associated with medial meniscus lesions (P = 0.047), while the younger age group (<30 years) had significantly higher lateral meniscal lesions (P = 0.008). Chronic ACL injuries (>3 months) had a significantly higher risk of medial meniscus lesions (P = 0.006). Age (>30 years) (P = 0.002) and obesity (BMI >30 kg/m2) (P = 0.043) were predictors of chondral lesions. Conclusion: Significant association is observed between age (>30 years), male gender, obesity, and chronicity with medial meniscal injuries in patients with an ACL injury, while younger patients (<30 years) and patient operated within 3 months had a higher incidence of lateral meniscus lesions. Age and BMI (>30 kg/m2) were predictors of chondral lesions in ACL injury.

Background: Meniscal and chondral lesions are commonly associated with anterior cruciate ligament (ACL) tears, and these lesions may play a role in patient outcomes after ACL reconstruction. Purpose: To determine the effects of the presence and location of meniscal and chondral lesions at the time of ACL reconstruction on patient-reported outcomes at a minimum 2-year follow-up. Study Design: Cohort study; Level of evidence, 3. Methods: Patients with no prior knee surgery who underwent primary ACL reconstruction by a single surgeon between 2010 and 2014 were included in this study. Those meeting inclusion criteria were divided into the following groups based on the arthroscopic diagnosis: patients without concomitant meniscal or chondral lesions, patients with isolated meniscal lesions, patients with isolated chondral lesions, and patients with both chondral and meniscal lesions. Patient-reported outcomes (Short Form–12 [SF-12] physical component summary [PCS] and mental component summary [MCS], Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC], and Lysholm scale) were assessed at a minimum of 2 years from the index surgery. Results: A total of 151 patients met the inclusion criteria and were included in the study. The mean age at the time of surgery was 36.2 years (range, 14-73 years), and the mean follow-up was 3.2 years (range, 2.0-5.6 years). At the time of surgery, 33 (22%) patients had no concomitant lesions and served as the control group, 63 (42%) patients had isolated meniscal lesions, 21 (14%) patients had isolated chondral lesions, and 34 (22%) patients had both chondral and meniscal lesions. There was significant improvement in all outcome scores postoperatively for the 3 groups ( P < .05 for all outcome scores). The presence of a meniscal tear and laterality of the meniscal lesion did not have a negative effect on any postoperative outcome scores. Patients with isolated chondral lesions had significantly lower postoperative WOMAC scores compared with patients without chondral lesions ( P < .05). No significant differences were found for all other scores. Patients with patellofemoral chondral lesions had significantly lower postoperative SF-12 PCS and Lysholm scores than patients with tibiofemoral chondral lesions ( P < .05). Conclusion: Patients with ACL tears achieved improved functional scores at a mean 3.2 years after ACL reconstruction. While meniscal lesions did not affect postoperative outcomes in the short term, chondral lesions were identified as a predictor for worse outcomes.

Background: Acute anterior cruciate ligament(ACL) rupture is associated with a significant incidence of concomitant meniscal and chondral injuries. However, to our knowledge, the incidence of these concomitant injuries in skeletally immature(SI) versus skeletally mature(SM) patients has not been directly compared. SI patients are a unique subset of ACL patients because surgical considerations are different, and subsequent re-tear rates are high. However, it is unclear if the rates and types of meniscal and chondral injuries differ. Purpose: The purpose of this study is to compare associated meniscal and chondral injury patterns between SI and SM patients under age 21, treated with ACL reconstruction for an acute ACL tear. We hypothesized that no significant differences would be seen. Methods: We performed a single-center retrospective review of primary ACL reconstructions performed from January 2012 to April 2020. Patients were stratified by skeletal maturity status based on a review of records and imaging. Demographic data was recorded, including age, sex, and BMI. Associated intra-articular meniscal injury, including laterality, location, configuration, and treatment were determined. Articular cartilage injury location, grade, and treatments were determined. Revision rates, non-ACL reoperation rates, and time to surgery were also compared between the two groups. Results: 785 SM and 208 SI patients met inclusion criteria. Mean BMI and mean age were significantly different between groups. Meniscal tear rates were significantly greater in SM versus SI patients in medial meniscus tears(P<.001), medial posterior horn tears(P=.001), medial longitudinal tears configuration(P=.007), lateral Radial configuration(P=.002), and lateral complex tears(P=.011). Medial repairs(P<.001) and lateral partial meniscectomies(P=.004) were more likely in the SM group. There was a significantly greater number of chondral injuries in the SM versus SI groups in the Lateral(p=.007) and medial compartments(P<.001). SM patients had a significantly increased number of outerbridge grade 1 and 2 in the Lateral(P<.001) and Medial Compartments(P=.013). ACL revisions(P=.019) and Non-ACL reoperations(P=.002) were significantly greater in the SI patients compared to SM. No other significant differences were noted. Conclusion: SM ACL injured patients have a significantly higher rate of medial meniscus tears and medial longitudinal configurations treated with repair, and a significantly higher rate of radial and/or complex lateral meniscus tears treated with partial meniscectomy compared to the SI group. We also found a significantly higher rate of both medial and lateral compartment chondral injuries, mainly grades 1 and 2, in SM compared to SI patients. Conversely, SI ACL reconstruction patients had higher revision and subsequent non-ACL surgery rates.

Background: Several long-term (≥20 years) follow-up studies after anterior cruciate ligament (ACL) reconstruction have been published in recent years, allowing for a systematic evaluation of outcomes. Purpose: To summarize outcomes at ≥20 years after ACL reconstruction and identify patient and surgical factors that affect these results. Study Design: Systematic review; Level of evidence, 4. Methods: Prospective studies of primary ACL reconstructions with hamstring or bone–patellar tendon—bone (BTB) autograft via an arthroscopic or a mini-open technique and with a mean follow-up of ≥20 years were identified. When possible, the mean scores for each outcome measure were calculated. Factors identified in individual studies as predictive of outcomes were described. Results: Five studies met the inclusion and exclusion criteria with a total of 2012 patients. The pooled mean follow-up for patient-reported outcome measures was 44.2% (range, 29.6%-92.7%) and in-person evaluation was 33.2% (range, 29.6%-48.9%). Four studies (n = 584) reported graft tears at a mean rate of 11.8% (range, 2%-18.5%) and 4 studies (n = 773) reported a contralateral ACL injury rate of 12.2% (range, 5.8%-30%). Repeat non-ACL arthroscopic surgery (4 studies; n = 177) to the ipsilateral knee occurred in 10.4% (range, 9.5%-18.3%) and knee arthroplasty (1 study; n = 217) in 5%. The pooled mean of the International Knee Documentation Committee subjective knee function (IKDC) score was 79.1 (SD, 21.8 [3 studies; n = 644]). In 2 studies (n?= 221), 57.5% of patients continued to participate in strenuous activities. The IKDC-objective score was normal or nearly normal in 82.3% (n = 496; 3 studies), with low rates of clinically significant residual laxity. Moderate-severe radiographic osteoarthritis (OA) (IKDC grade C or D) was present in 25.9% of patients (n = 605; 3 studies). Medial meniscectomy is associated with increased risk of radiographic OA. Radiographic OA severity is associated with worse patient-reported knee function, but the association with knee pain is unclear. Conclusion: Currently available prospective evidence for ACL reconstruction with hamstring or BTB autograft provides several insights into outcomes at 20 years. The rates of follow-up at 20 years range from 30% to 93%. IKDC-objective scores were normal or nearly normal in 82% and the mean IKDC-subjective score was 79 points.

Abstract Introduction: Anterior cruciate ligament (ACL) rupture is one of the most common lesions in knee traumatology; therefore the number of ACL reconstructions is increasing worldwide. Usually, an anteromedial (AM) accessory portal is required in anatomical positioning of the femoral tunnel, which is not absolutely necessary in this technique. Aim: Assessment of all-inside ACL reconstruction preliminary clinical results with adjustable loops and buttons on both femoral and tibial surfaces. Method: Our prospective study included 28 subjects (19 male, 9 female) with chronic ACL ruptures. The mean age of the study population was 27.72 ± 8.23 years. In all cases ACL reconstruction was carried out with the use of quadrupled semitendinosus auto-grafts with adjustable loops and buttons on the femoral and tibial surfaces and anatomic placement of both tunnels, using an outside-in technique, with flipcutters (Arthrex®). Clinical and radiological evaluations were carried out before surgery and at 3 and 6 months postoperatively, with the Lysholm scoring system, the Tegner activity scale and anterior-posterior and latero-lateral X-rays. Anterior knee laxity was measured in 25° of flexion using a portable arthrometer (RolimeterTM, Aircast®) and maximum manual force. Results: During the final follow-up, the Lysholm score was good and excellent in 27 cases, with a mean Lysholm score of 95.55 ± 4.63; all results were classified as good. The mean preoperative Tegner activity score was 3.46 ± 1.71 (range: 1-7), and the post-operative mean score was 5.75 ± 2.24 (range: 2-10). We found no graft ruptures. Preoperative knee laxity measurements showed a mean displacement of 11.5 ± 3.1 mm and side-to-side differences of 5.6 ± 3.5 mm, while the postoperative measurements at the last follow-up were 6.3 ± 1.54 mm and 2.65 ± 1.86 mm, respectively. Conclusion: Short-term clinical outcomes of all-inside ACL restoration with anatomic placement femoral and tibial tunnels seem to recommend this surgical option, with good subjective and objective results. Additional research will have to prove the long-term success.

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.

AbstractTwo-stage revision anterior cruciate ligament (ACL) reconstruction is an effective way to revise suboptimal tunnel-placement allowing for proper graft fixation. However, prolonged increased laxity of the knee may increase the risk of meniscal or chondral injury. It was hypothesized that no additional meniscal or chondral lesions occur in between the two stages of the two-stage revision ACL reconstruction. In this retrospective study, 42 patients undergoing a two-stage revision ACL reconstruction were included. Surgical notes for both stages were screened for meniscal and chondral status, interventions to any concurrent injury, surgery dates, along with basic patient characteristics. In 4 of the 42 patients, a new meniscal tear occurred in between the two stages, of which three required partial meniscectomy during the second stage of the ACL revision. One patient experienced a new small degenerative tear that did not require intervention.
