AbstractThe incidence of meniscal tear was reported to increase with the delay of anterior cruciate ligament reconstruction (ACLR). The tear may occur concurrently with the ACL injury or after the ACL injury. Few studies had focused on the patients whose meniscus is intact during ACL injury. We determined the correlation between timing of surgery and incidence of meniscal tears in ACL-deficient knees with initially intact meniscus. We retrospectively reviewed 387 patients who had undergone primary ACLR. Time of initial ACL injury, magnetic resonance imaging (MRI) examination, and surgery was recorded. The MRI was reviewed by experienced radiologic and orthopaedic doctors. Intraoperative arthroscopic images were also obtained and reviewed. The type of tear noted during surgery was classified according to the modification of International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine classification of meniscal tears. Patients were divided into early (surgery within 12 months from injury) and late surgery group (surgery at more than 12 months from injury). There were 216 patients with intact medial meniscus and 257 patients with intact lateral meniscus on the postinjury MRI study. The incidence of medial meniscus tear (MMT) was significantly higher than lateral meniscus tear (LMT) during the ACLR (33.8 vs. 19.8%, p < 0.001). The incidence of MMT is higher in late group than in early group (53.7 vs. 29.1%, p = 0.004, odds ratio= 2.815). The incidence of LMT is mildly higher in late group but without statistics significance (23.8 vs. 18.6%, p = 0.364). In both MMT and LMT, the most common injury pattern observed was a longitudinal tear. The incidence of each type is not different between early and late group. For patients without concurrent meniscal injuries with the ACL tear, the incidence of MMT significantly increased if ACLR was performed more than 12 months after injury. The medial meniscus was more prone to injury than the lateral meniscus in chronic ACL-deficient knee. ACLR should be performed earlier to reduce the risk of meniscal tears for patients without initially concurrent meniscal tear.

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.

Objectives: This prospective case–control study was conducted with primary aim to compare the value of magnetic resonance imaging (MRI) in terms of accuracy, sensitivity, specificity, positive predictive value, and negative predictive value for the detection of meniscal tear in anterior cruciate ligament (ACL)-deficient and ACL-intact groups. The secondary aim was to identify if the sensitivity and accuracy differ if the MRI is older than 3 months from the time of surgery. Materials and Methods: There were 255 patients enrolled into this study out of which 207 fulfilled the inclusion criteria. Among 207, 138 underwent surgery within 1 month of MRI, 30 had 1–3 months delay, and 39 cases underwent surgery more than 3 months after their MRI. Among 167 patients who underwent surgery within 3 months of MRI, 97 had ACL tear and 71 had intact ACL. Results: The overall sensitivity for lateral meniscus tear (68.2%) is significantly lower than the medial meniscus tear (92.9%). The sensitivity of MRI for medial meniscus tear in ACL-deficient knee is lower than ACL-intact knees (90% vs. 96.2%, P = 0.3). Similarly, the sensitivity is significantly lesser for lateral meniscus tear in ACL-deficient knee compared to ACL-intact knee (50% vs. 83.3%, P = 0.009). The sensitivity of MRI for both the lateral and medial meniscus tear decreased if the MRI performed 3 months before the surgery. Conclusion: Patients with ACL-deficient knee have to be counseled for intraoperative detection of lateral meniscus tear as the sensitivity of MRI for lateral meniscus tear in ACL-deficient group is low. Similarly, if the MRI is more than 3 months old from the time of surgery, we recommend to repeat the MRI as the sensitivity decreases significantly.

Lithuanian University of Health Sciences, Department of Orthopaedics and Traumatology, Kaunas, Lithuania 12 months (25 (46.3%)), (P &lt; 0.001). The examination of possible risk factors for medial meniscus tear revealed, that BMI (overweight) (OR=2.04; 95% CI=1.091-3.814) and time from injury to surgery (weeks) (OR=1.026; 95% CI=1.012-1.04) significantly increased possibility of medial meniscus tear. We found no significant laxity difference between postoperative testings’ (3, 6 and 12 months after surgery) and the three groups, created by the time to surgery. Conclusion. The study revealed a significant difference in the incidence of meniscal tears between patients treated in the early group and in those underwent ACL-R after 12 months, which lead to significantly higher chance (every delayed week increase chance by 1.026 times and overweight (BMI ≥ 25 kg/ m2) increase chance by 2.04 times) of a medial meniscal tear occurring in patients undergoing delayed reconstruction.

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.

Abstract Purpose To investigate the potential factors associated with the prevalence of meniscal repair Methods Patients who received partial meniscectomy or meniscal repair in our institution from Jan 2015 to Dec 2019 were included in current study. The inclusion criteria were (1) meniscus tear treated using meniscectomy or repair, (2) with or without concomitant anterior cruciate ligament reconstruction, (3) not multiligamentous injury. Demographic data, including sex, age, body mass index (BMI), injury-to-surgery interval and intra-articular factors such as the location of injury, medial or lateral, ACL rupture or not and the option of procedure (partial meniscectomy or repair) were documented from medical records. Univariate analysis consisted of chi-square. Multivariate logistic regression was then performed to adjust for confounding factors. Results 592 patients including 399 males and 193 females with a mean age of 28.7 years (range from 10 to 75 years) were included in current study. In the univariate analysis, male (p = 0.002), patients aged 40 years or younger (p < 0.001), increased weight (p = 0.010), Posterior meniscus torn (0.011), concurrent ACL ruputure (p < 0.001), lateral meniscus (p = 0.039) and early surgery (p < 0.001) were all associated with the prevalence of meniscal repair. However, After adjusting for confounding factors, we found that age (OR, 0.35; 95% CI, 0.17 - 0.68, p = 0.002), ACL injury (OR, 3.76; 95% CI, 1.97 – 7.21, p < 0.001), side of menisci (OR, 3.29; 95% CI, 1.43 – 7.55, p = 0.005), site of tear (OR, 0.15; 95% CI, 0.07 – 0.32, p < 0.001), and duration of injury (OR, 0.46; 95% CI, 0.28 – 0.82, p = 0.008) were associated with the prevalence of meniscus repair. Conclusions Meniscal tear in aged patients especially those with concomitant ACL injury is likely to be repaired. Additionally, in order to increase the prevalence of repair and slow down progression of OA, the surgical procedure should be performed within two weeks after meniscus tear especially when the tear is located at lateral meniscal posterior. Study design Case-control study; level of evidence, 3.

Abstract Background The Multicenter Orthopaedic Outcomes Network (MOON) group recently reported that medial meniscus (MM) repairs are associated with more frequent re-operations when compared to lateral meniscus (LM) repairs. The purpose of this study was to compare the meniscal healing and the incidence of subsequent re-operation of medial and lateral meniscal tears that occurred concurrently with anterior cruciate ligament (ACL) injuries. Methods We retrospectively reviewed patients who underwent second-look arthroscopy after primary ACL reconstruction (ACLR) between June 2005 to December 2016. The healing of meniscal tears following repair or left in situ, and re-tear following partial meniscectomy, were evaluated via second-look arthroscopy and compared between medial and lateral meniscus. Moreover, the incidence of subsequent meniscal re-operation after the index ACLR were investigated and compared between medial and lateral meniscus. Subsequent meniscal re-operation was performed in cases of the following three symptomatic meniscus tears: re-tears at the meniscectomy site; new tears; and failed healing of repaired or left in situ meniscus. Results There were 148 meniscal tears in 121 patients at index ACLR. There were 62 MM tears, 38 LM tears, and 24 bilateral meniscus tears. At second-look arthroscopy, the “successful healing” rate for tears following repair was higher in LM tears (91.2%) compared to MM tears (80.0%), although it was not statistically significant (p > 0.05). No significant differences were observed in the healing of left in situ tears or re-tear of meniscectomy site between medial and lateral meniscus. Patients with MM tears combined with ACL injuries had a higher incidence of subsequent meniscal re-operation compared to patients with LM tears (25.6% vs 16.1%, p = 0.025). Conclusions There was a trend for the successful healing rate to be higher in LM repairs than MM repairs. Subsequent meniscal re-operations after ACLR were more frequent in patients with medial meniscal tears concurrently with ACL injuries in comparison to patients with lateral meniscal tears. Level of study Level IV, retrospective case series.

Background: Anterior cruciate ligament (ACL) injury is one of the most frequent orthopaedic injuries and reasons for time loss in sports and carries significant implications, including posttraumatic osteoarthritis (OA). Instability associated with ACL injury has been linked to the development of secondary meniscal tears (defined as tears that develop after the initial ACL injury). To date, no study has examined secondary meniscal tears after ACL injury and their effect on OA and arthroplasty risk. Purpose: To describe the rates and natural history of secondary meniscal tears after ACL injury and to determine the effect of meniscal tear treatment on the development of OA and conversion to total knee arthroplasty (TKA). Study Design: Cohort study; Level of evidence, 3. Methods: A geographic database of >500,000 patients was reviewed to identify patients with primary ACL injuries between January 1, 1990, and December 31, 2005. Information was collected with regard to ACL injury treatment, rates/characteristics of the secondary meniscal tears, and outcomes, including development of OA and conversion to TKA. Kaplan-Meier and adjusted multivariate survival analyses were performed to test for the effect of meniscal treatment on survivorship free of OA and TKA. Results: Of 1398 primary ACL injuries, the overall rate of secondary meniscal tears was 16%. Significantly lower rates of secondary meniscal tears were noted among patients undergoing acute ACL reconstruction within 6 months (7%) as compared with patients with delayed ACL reconstruction (33%, P < .01) and nonoperative ACL management (19%, P < .01). Of the 235 secondary meniscal tears identified (196 patients), 11.5% underwent repair, 73% partial meniscectomy, and 16% were treated nonoperatively. Tears were most often medial in location (77%) and complex in morphology (56% of medial tears, 54% of lateral tears). At the time of final follow-up, no patient undergoing repair of a secondary meniscal tear (0%) underwent TKA, as opposed to 10.9% undergoing meniscectomy and 6.1% receiving nonoperative treatment ( P = .28). Conclusion: Secondary meniscal tears after ACL injury are most common among patients undergoing delayed surgical or nonoperative treatment of their primary ACL injuries. Secondary tears often present as complex tears of the medial meniscus and result in high rates of partial meniscectomy.

AbstractThe meniscus is one of the most important structures of the knee that needs to be saved if possible. Previous studies showed that increasing time from an anterior cruciate ligament (ACL) injury (TFI) could lead to a meniscal tear, especially medial meniscus (MM). We developed the present study to see if the TFI alone is a predictor of meniscal injury in ACL-deficient knees. We included 111 patients who had a reconstructed ACL injury at our institution from March 2015 to March 2016 in this retrospective cohort study. All demographic data, including age, gender, and body mass index (BMI), were collected. We also recorded the mechanism of injury and the TFI. We extracted the meniscal condition at the time of surgery from the surgical report. All patients were followed up for a mean of 23 months, and the Lysholm score and pain visual analog scale (VAS) score were obtained. The mean TFI of patients with MM tear was 17.4 ± 16.8 months, which was significant than the patients with lateral meniscal (LM) tear (9.3 ± 8.3 months) and intact meniscus (7.4 ± 8.1 months) (p = 0.001). Patients with TFI less than 6 months had a significantly lower rate of MM tear, and increasing TFI more than 6 months could increase the rate of MM tear (p = 0.001). We could not find any association between age, BMI, and gender and meniscal injury. At the latest follow-up, Lysholm and VAS scores in patients with and without meniscal tear were the same. Our study confirms that increasing time from the ACL injury would increase the risk of MM damage. The cutoff point for this risk factor is 6 months from initial injury; therefore, to save the meniscus, it might be better to perform ACL reconstruction within 6 months in ACL-deficient knees.

Background: Anterior cruciate ligament (ACL) tears are frequently associated with meniscal injury. Numerous authors have described associations between the presence of a meniscal tear at the time of ACL reconstruction and time to surgery and number of instability episodes1-3. The purpose of this study was to evaluate the relationship between age and the presence of a meniscal tear at the time of ACL reconstruction in children and adolescents. Methods: A single-institution retrospective review was performed of consecutive pediatric and adolescent patients who underwent ACL reconstruction over a 3.5-year period at a single institution. Inclusion criteria were age less than 20 years and an ACL injury treated with knee arthroscopy and ACL reconstruction. Patients with multiligament knee injuries were excluded. A chart review was performed to obtain demographic information and intra-operative findings. Meniscus tears were defined as tears documented during diagnostic arthroscopy. Results: Four hundred sixty-one patients met inclusion criteria, including 226 males (49%) and 235 females (51%) with a mean age of 15 years (range 7 – 20 years). The right and left knees were affected equally. Two hundred seventy patients (80%) had intra-operative evidence of a meniscal tear, including 215 lateral meniscus tears (56%) and 119 medial meniscus tears (44%). Sixty-four patients (14%) had both medial and lateral meniscus tears. Age at surgery was found to be a statistically significant independent predictor of the presence of a meniscus tear, odds ratio=1.14, 95% CI (1.05 – 1.25), p=0.003. For every 1-year increase in age, there is a 14% increase in the odds of having a meniscus tear and this is depicted in the figure below. Among patients 13 years of age and younger (n = 89), 47% had a meniscus tear. In contrast, 62% of patients 14 – 19 years of age (n = 301) had a meniscus tear, which was significantly greater (p = 0.01). Age was also a statistically significant independent predictor following subgroup analysis of medial and lateral meniscus tears. For every one year increase in age at surgery, there was a 21% increase in the odds of having a medial meniscus tear (odds ratio = 1.21, 95% CI: (1.08 – 1.35), p<0.001) and a 13% increase in the odds of having a lateral meniscus tear (odds ratio = 1.13, 95% CI: (1.04 – 1.24), p=0.01. Conclusions: Among children and adolescents with anterior cruciate ligament tears, for every 1-year increase in age, there is a 14% increase in the odds of having a meniscus tear. Adolescents over the age of 13 years had a significantly greater rate of meniscus tears than did those 13 years of age and younger. A complete arthroscopic examination with close attention to the menisci is required to diagnose and treat meniscal tears. Surgeons should be comfortable with all meniscus repair techniques, including inside-out, outside-in, all-inside, radial, and transosseous root repairs as the majority of children and adolescent patients with ACL tears also have an associated meniscus tear.

Time From Injury

Background: Anterior cruciate ligament (ACL) tears are frequently associated with meniscal tears. Previous studies have shown that secondary meniscal tears—occurring after the initial ACL injury—are associated with greater delays from injury to ACL reconstruction (ACLR), but frequently use dichotomous categories of acute versus delayed ACLR. Purpose: As meniscal damage is likely accrued constantly over time, we investigated the variability of concurrent meniscal injuries as a function of time from injury to ACLR in a pediatric and adolescent population. Methods: We performed a retrospective review of all patients ≤18 years who underwent an ACLR between 2014 and 2018 at one of two tertiary academic hospitals. Outliers were excluded if time from injury to ACLR was greater than 78 weeks. Records were reviewed to assess patients’ dates of injury and surgery. The prevalence of concurrent medial and/or lateral meniscal injury was evaluated at the time of surgery for each patient. Adjusted relative risks (ARRs) of meniscal injury were calculated using Poisson regression models adjusted for age, sex, and body-mass index. Logistic regression was used to model the predicted probability of medial meniscal tears. Results: 546 patients met inclusion criteria. The mean age of participants was 15.3 years (S.D., 1.6), and 277 (50.7%) patients were male. Overall, 344 (63.0%) patients had a meniscal tear. 169 (49.1%) tears occurred at the medial meniscus, and 257 (74.7%) occurred at the lateral meniscus (Table 1). Compared to females, males had a greater risk of lateral meniscal injury (ARR, 1.46; 95% CI, 1.20-1.77) but not medial meniscal injury (ARR, 1.01; 95% CI, 0.77-1.31) (Figure 1). When considering all meniscal tears, time from injury to ACLR was not associated with increased risk of a tear (ARR, 1.01; 95% CI, 1.00-1.01). However, for medial meniscal tears, there was a significant association between time from injury to ACLR, in weeks, and meniscal tears (ARR, 1.02; 95% CI, 1.01-1.03, P = 0.003). A ten-week delay was associated with a 20% increased risk of medial meniscal injury (Figure 2). Conclusion: In pediatric and adolescent ACLR patients, the risk of any meniscal injury was not associated with delay from injury to surgery. However, the risk of medial meniscal injury increased by 2% each week from injury to surgery. [Table: see text][Figure: see text][Figure: see text]
