Zhao Y, Coppola A, Karamchandani U, Amiras D, Gupte CM. Artificial intelligence applied to magnetic resonance imaging reliably detects the presence, but not the location, of meniscus tears: a systematic review and meta-analysis. Eur Radiol 2024; 34:5954-5964. [PMID: 38386028 PMCID: PMC11364796 DOI: 10.1007/s00330-024-10625-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2023] [Revised: 12/24/2023] [Accepted: 01/13/2024] [Indexed: 02/23/2024]
Abstract
OBJECTIVES To review and compare the accuracy of convolutional neural networks (CNN) for the diagnosis of meniscal tears in the current literature and analyze the decision-making processes utilized by these CNN algorithms. MATERIALS AND METHODS PubMed, MEDLINE, EMBASE, and Cochrane databases up to December 2022 were searched in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement. Risk of analysis was used for all identified articles. Predictive performance values, including sensitivity and specificity, were extracted for quantitative analysis. The meta-analysis was divided between AI prediction models identifying the presence of meniscus tears and the location of meniscus tears. RESULTS Eleven articles were included in the final review, with a total of 13,467 patients and 57,551 images. Heterogeneity was statistically significantly large for the sensitivity of the tear identification analysis (I2 = 79%). A higher level of accuracy was observed in identifying the presence of a meniscal tear over locating tears in specific regions of the meniscus (AUC, 0.939 vs 0.905). Pooled sensitivity and specificity were 0.87 (95% confidence interval (CI) 0.80-0.91) and 0.89 (95% CI 0.83-0.93) for meniscus tear identification and 0.88 (95% CI 0.82-0.91) and 0.84 (95% CI 0.81-0.85) for locating the tears. CONCLUSIONS AI prediction models achieved favorable performance in the diagnosis, but not location, of meniscus tears. Further studies on the clinical utilities of deep learning should include standardized reporting, external validation, and full reports of the predictive performances of these models, with a view to localizing tears more accurately. CLINICAL RELEVANCE STATEMENT Meniscus tears are hard to diagnose in the knee magnetic resonance images. AI prediction models may play an important role in improving the diagnostic accuracy of clinicians and radiologists. KEY POINTS • Artificial intelligence (AI) provides great potential in improving the diagnosis of meniscus tears. • The pooled diagnostic performance for artificial intelligence (AI) in identifying meniscus tears was better (sensitivity 87%, specificity 89%) than locating the tears (sensitivity 88%, specificity 84%). • AI is good at confirming the diagnosis of meniscus tears, but future work is required to guide the management of the disease.

A Recess Is Observed Between the Posterior Knee Capsule and the Meniscotibial Ligament Complex in Pediatric Specimens. Arthrosc Sports Med Rehabil 2024; 6:100852. [PMID: 39006787 PMCID: PMC11240032 DOI: 10.1016/j.asmr.2023.100852] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Accepted: 11/19/2023] [Indexed: 07/16/2024] Open
Abstract
Purpose To define the surgical anatomy of the meniscotibial ligament complex of the pediatric medial and lateral menisci and their relation to the proximal tibial physis and posterior joint capsule. Methods Fourteen pediatric cadaveric knee specimens (aged 3 months to 11 years) were dissected to clarify the relation of the posterior knee capsule, the meniscus, and the meniscotibial ligament complex. Metallic markers were placed marking the meniscotibial ligament capsular attachment on the proximal tibia. Specimens underwent computed tomography scanning to evaluate pin placement and relation to the physis. A digital measurement tool was used to measure the distances between the proximal tibial physis and the pins (placed at 5 points on both the lateral and medial menisci). Results In each specimen, clear separation was noted between the posterior joint capsule from the meniscus and meniscotibial ligament complex in the medial and lateral compartments. There was an increase in the distance between the proximal tibial physis and the insertion points of the meniscotibial ligament complex with increasing specimen age. For both the medical and lateral menisci in group 1, the median meniscotibial ligament insertion points were often less than 7 mm (interquartile range, 0.00-7.8 mm) away from the physis. The median meniscotibial ligament insertion points in group 2 tended to be farther from the physis but always less than 20 mm (interquartile range, 2.5-17.5 mm)-and as close as less than 5 mm (lateral posterior root). Conclusions In this anatomic study of pediatric knees, we observed a distinct recess/cul-de-sac space between the posterior knee capsule and meniscal attachments in all specimens. This defines a distinct plane between the posterior knee capsule and the meniscotibial ligament complex, with a distance between the physis and meniscotibial ligament capsular attachments that increases with age. Clinical Relevance The anatomic parameters evaluated in our study should be considered as future meniscal repair and transplantation techniques aim to restore the meniscal anatomy, stability, and mobility provided by the meniscotibial ligament complex and capsule structures.

Abstract
The meniscal roots are critically important for maintaining knee stability, functional load distribution, and proper knee kinematics. Although adult meniscal root injuries have been a topic of increasing research, medial meniscus injuries also occur in pediatric and adolescent patients, with up to 2% of meniscal injuries involving root attachments. The purpose of this Technical Note is to demonstrate the transosseous repair of isolated posterior medial meniscal root injuries in children and adolescents, including tear visualization on magnetic resonance imaging and during arthroscopy, operative technique, and postoperative management.

Abstract
Anterior cruciate ligament (ACL) rupture often presents with a tear of the posterior horn of the lateral meniscus. There is no clear preference between ACL reconstruction with suture and resection of the meniscus. We aimed to compare the clinical efficacy of ACL reconstruction with suture versus resection in patients presenting with arthroscopic ACL rupture and radial complete tear of the posterior corner of the lateral meniscus. We retrospectively analyzed 157 patients with ACL rupture and complete radial tear of the posterior horn of the lateral meniscus. Between May 2010 and April 2015, 86 of 157 patients underwent ACL reconstruction and meniscus suture (study group, 54.78%) and 71 of 157 patients underwent ACL reconstruction and meniscus resection (control group, 45.22%) in our department. All patients were monitored over the 12 to 72-month follow-up period. The primary evaluation indices were the Lysholm scores, the International Knee Documentation Committee (IKDC) scores, pivot shift test, the Barret criteria, and magnetic resonance imaging (MRI) findings of meniscal healing. The majority of 157 patients were relatively young men (29.64 ± 7.79 years) with low body mass index (BMI) (23.79 ± 2.74). The postoperative Lysholm and IKDC scores of the two groups were significantly improved over the corresponding preoperative scores (p < 0.05). The clinical results and excellent and good rates were significantly better for the study group than for the control group (both, p < 0.05). MRI showed that the meniscal healed rate of the study group was 96.51%. There was no significant difference in BMI between subgroups for any functional outcome. For patients with ACL rupture and complete radial tear of the posterior horn of the lateral meniscus, ACL reconstruction and both simultaneous suture and resection of the posterior horn of the lateral meniscus were found to be safe and effective. There was no association between outcomes and BMI. However, the former was associated with a superior long-term clinical effect and may restore the integrity of the meniscus and is particularly recommended for young patients.

Abstract
BACKGROUND Intact meniscus roots are a prerequisite for normal meniscal function, including even distribution of compressive forces across the knee joint. An injury to the root disrupts the hoop strength of the meniscus and may lead to its extrusion and the development of osteoarthritis. A medial meniscus posterior root tear (MMPRT) is often thought to have a primary degenerative pathogenesis. However, there is mention of some cases of MMPRTs where the patients have a solely traumatic injury to a previously healthy meniscus. PURPOSE To describe a subpopulation of patients with traumatic MMPRT. STUDY DESIGN Systematic review; Level of evidence, 5. METHODS The Web of Science database (www.webofscience.com) was queried using the Medical Subject Headings term "medial root tear." Articles were reviewed, and those evaluated for MMPRTs in a degenerative meniscus were excluded. A total of 25 articles describing cases of acute traumatic causes were included in this study. For these articles, the patient characteristics, injury mechanisms, and concomitant injuries evaluated were recorded and pooled. RESULTS The search revealed 660 articles, and 25 were selected for inclusion. A total of 113 patients with a traumatic MMPRT were identified and included in this review. The study population had a mean age of 27.1 years and a high share of men (64%). Also, this review displays how most patients with traumatic MMPRTs also suffer concomitant injuries (68%). CONCLUSION The findings in this review support our hypothesis that there is a unique subgroup with acute traumatic MMPRTs that have unique patient characteristics, injury mechanisms, and combined injuries, compared with previously published reviews on MMPRTs.

Abstract
BACKGROUND The use of postoperative MRI to assess the healing status of repaired menisci is a long-standing issue. This study evaluates and compares functional and MRI outcomes following an arthroscopic meniscus repair procedure with the aim of postoperative MRI diagnostic accuracy clarification in young patients. METHODS A total of 35 patients under 18 years old who underwent isolated meniscus repair were included. The Pedi-IKDC score, Lysholm score, and Tegner activity index (TAS) were compared between the groups formed according to the Stroller and Crues three-grade classification of postoperative MRI-based evaluations. Grade 3 MRI views were classified as unhealed, grade 2 as partially healed, and grade 1 as fully healed within the repaired meniscus, whereas grade 3 cases were considered unsuccessful due to MRI evaluation. RESULTS MRI assessment revealed 4 cases of grade 1 (11.4%), 14 cases of grade 2 (40.8%), and 17 cases of grade 3 (48.0%) lesions. Pedi-IKDC and TAS scores were significantly higher among MRI grade 2 patients than among MRI grade 3 patients (p < 0.05). Weak negative correlations between MRI grades and all functional scales were found (p < 0.05). ROC analysis showed that Pedi-IKDC and TAS scores could correctly classify 77% and 71% of MRI grade 3 patients, respectively. The optimal cut-off values to detect grade 3 patients were 88.74 for the Pedi-IKDC score and 4.5 for the TAS score. CONCLUSIONS To conclude, established functional score cut-off values may help identify unhealed meniscus repair patients.

Abstract
PURPOSE To report midterm outcomes after primary medial and lateral meniscal allograft transplantation (MAT) with fresh-frozen allografts implanted with the bridge-in-slot technique in the adolescent patient population. METHODS Adolescent patients less than 18 years old at the time of primary MAT from 1999 to 2016 were retrospectively identified. International Knee Documentation Committee (IKDC) subjective form, Lysholm, and Knee Injury and Osteoarthritis Outcome Score (KOOS) subscales scores were collected before surgery and at 1-year, 2-year, and a minimum 5-year follow-up. Thresholds for achieving clinically significant outcomes were calculated, and the proportion of patients achieving minimal clinically important difference (MCID), patient-acceptable symptomatic state (PASS), and substantial clinical benefit (SCB) was determined. Meniscus reoperation (partial, subtotal, or total meniscectomy, repair, or failure) and failure (revision MAT or conversion to arthroplasty) rates were determined. RESULTS Forty-four (female n = 33; male n = 11) of 62 identified patients met inclusion criteria and were followed for a mean of 9.5 ± 3.8 years (range, 5.0-17.7). Lateral MAT was performed in most patients (n = 35/44 [80%]). Isolated MAT was performed in 27 (61%) patients. Common concomitant procedures included osteochondral allograft transplantation (32%), autologous chondrocyte implantation (18%), and anterior cruciate ligament reconstruction (14%). MCID, PASS, and SCB were achieved by patients at a minimum 5-year follow-up for IKDC (62%; 76%; 31%), Lysholm (62%; 79%; 23%), and KOOS questionnaires (Pain [65%; 81%; 41%], Symptoms [58%; 81%; 47%], Activities of Daily Living [53%; 77%; 35%], Sport [86%; 75%; 50%], and Quality of Life [59%; 81%; 59%]), respectively. Fourteen patients (32%) underwent reoperation at an average of 5.0 ± 4.3 years (range, 0.8-14.0) after MAT. Three (7%) patients met criteria for failure, requiring revision MAT an average of 3.8 ± 1.1 years (range, 2.8-4.9) after transplantation. No patients underwent arthroplasty. Overall survival free from failure at 1, 2, 5, and 10 years was 100%, 100%, 93%, and 93%, respectively. At the time of final follow-up, 80% of patients reported satisfaction with their current physical status. CONCLUSIONS Primary MAT in adolescent patients resulted in significant and durable functional improvements at mid- to long-term follow-up. At an average of 9.5 years after surgery, meniscal reoperation rate was 32% whereas graft survival free of revision MAT was 93%. Adolescents undergoing MAT demonstrated similar functional outcomes and graft survivability when compared to available adult MAT literature. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
Introduction To investigate the epidemiological features and prevalence of cruciate ligament injuries (CLI) in children and adolescents, and to examine the potential risk factors associated with concomitant meniscal tear (MT) among this population. Methods The demographic data and injury details of children and adolescents with CLI from Southeast China were analyzed to describe their distribution characteristics, alongside an analysis of the prevalence of MTs, the most frequent complication. In addition, binary logistic analysis was employed to ascertain the risk factors linked to MT in individuals suffering from CLI. Results A total of 203 patients with CLI (n = 206) met the inclusion criteria, with a male-to-female ratio of 2.3:1. Notably, a higher proportion of females were aged ≤16 years old compared to males, who predominated in patients aged >16 years (P = 0.001). Among children and adolescents, anterior cruciate ligament (ACL) injuries were the primary type of CLI, accounting for 88.18% (179/203) of all cases. The majority of cases (132/203, 65.02%) were sustained during sports activities, and sprains were the predominant mechanism of injury (176/203, 86.7%). Additionally, the most common associated injury was an MT (157/203, 77.34%). The posterior horn is the most frequently affected site for both medial MT (62.93% out of 73 cases) and lateral MT (70.19% out of 73 cases). Moreover, vertical tears constituted the majority of medial MTs (59.48% out of 116 cases). Furthermore, patients with a higher BMI faced an increased risk of associated MT in comparison to non-overweight patients (88% vs. 73.86%; P = 0.038). Each increase in BMI unit was linked with a 14% higher probability of associated MT occurrence in children and adolescents with CLI (OR = 1.140; P = 0.036). Discussion ACL injuries are a common form of knee ligament injury among children and adolescents, especially those over the age of 16, and are often the result of a sprain. Meniscal posterior horn injury is the most commonly associated injury of youth with CLI. Additionally, overweight or obese people with CLI are at a greater risk of developing MT.

[PMID: 38532765 PMCID: PMC10964461 DOI: 10.1177/23259671241237810] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Accepted: 09/18/2023] [Indexed: 03/28/2024] Open
Abstract
Background Little is known on how meniscal morphology develops during skeletal growth and maturation and its subsequent relationship with the corresponding bony anatomy. Hypotheses (1) Meniscal dimensions and morphology would change by age during skeletal growth and maturation in different ways in boys compared with girls. (2) Morphological features of the medial and lateral menisci would correlate to medial and lateral femoral condyle curvatures. Study Design Cross-sectional study; Level of evidence, 3. Methods Anatomic features of the medial and lateral menisci were measured on magnetic resonance imaging scans from 269 unique knees (age, 3-18 years; 51% female) with no prior history of injury, congenital or growth-related skeletal disorders, or bony deformities. Morphological shape-based measurements were normalized to tibial plateau width or determined as ratios of meniscal dimensions. The association between age and anatomy was analyzed with linear regression. Two-way analysis of variance with the Holm-Šídák post hoc method was used to compare anatomy between sexes in different age groups. Linear regression was used to evaluate the relationship between femoral condyle curvature radius and meniscal morphology in each compartment after adjusting for age and sex. Results Meniscal length, width, horn distance, mean cross-sectional area (CSA), and mean height increased with age in both sexes (R2 > 0.1; P < .001). Age-related changes in meniscal morphology were seen in normalized length, width, horn distance, and mean height; width-to-length ratio; horn distance-to-length ratio (lateral meniscus only); normalized mean CSA (except lateral meniscus in girls); and mean tip angle (R2 > 0.04; P < .02). Sex-based differences were also found, with some morphological differences (normalized length and height) throughout development (P < .03) and size differences (length, width, and mean CSA) in later development (P < .01). After adjusting for age and sex, there were significant correlations between medial condyle curvature radius and normalized width, width-to-length ratio, horn distance, horn distance-to-length ratio, mean CSA, and mean height of the medial meniscus (P≤ .041) and between lateral condyle curvature radius and normalized length, mean height, and mean tip angle of the lateral meniscus (P≤ .004). Conclusion Age-related changes in meniscal dimensions and morphology, most notably a nonuniform growth pattern in meniscal geometry, occurred during skeletal growth and maturation, with different trends in boys than in girls.

Skeletal Radiol 2023:10.1007/s00256-023-04543-w. [PMID: 38153433 DOI: 10.1007/s00256-023-04543-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Revised: 12/07/2023] [Accepted: 12/07/2023] [Indexed: 12/29/2023]
Abstract
OBJECTIVE To systematically investigate the prevalence of knee MRI findings among symptomatic pediatric soccer players with respect to skeletal maturity and to identify predictors of surgery. METHODS This IRB-approved, HIPAA-compliant retrospective study included soccer players (< 18 years of age) who underwent MRI examinations in the past 5 years (2018-2023). Two radiologists retrospectively and independently reviewed all examinations to categorize skeletal maturity and to identify osseous and soft tissue findings. Findings were compared between maturation groups, and logistic regression models were used to identify predictors of surgery. RESULTS Ninety-seven players (45 boys, 52 girls) included 39 skeletally immature, 21 maturing, and 37 mature knees. Kappa coefficient for interobserver reliability ranged between 0.65 and 1.00. Osgood-Schlatter disease (OSD) was more common among immature than maturing and mature knees (25% vs 14% and 5%, p = 0.04); anterior cruciate ligament (ACL) injury was more common among maturing and mature than immature knees (59% and 48%, vs 15%, p < 0.01); and meniscal tears were more common among mature than immature and maturing knees (medial, 41% vs 18% and 14%, p = 0.03; lateral, 43% vs 21% and 19%, p = 0.04). Players in the mature group were more likely to undergo surgery (p = 0.01). The presence of an effusion (OR = 19.5, 95% CI 2.8-240.9, p = 0.01), ACL injury (OR = 170.0, 95% CI 1.3-6996.9, p < 0.01), and lateral meniscal tears (OR = 10.8, 95% CI 1.8-106.1, p = 0.02) were independent predictors of surgery. CONCLUSION Differential patterns of injury were found among symptomatic pediatric soccer players; the presence of an effusion, ACL injury, and lateral meniscal tears were independent predictors of surgery, likely contributing to the higher rates of surgery among skeletally mature players.

Abstract
The menisci increase the contact area of load bearing in the knee and thus disperse the mechanical stress via their circumferential tensile fibers. Traumatic meniscus injuries cause mechanical symptoms in the knee, and are more prevalent amongst younger, more active patients, compared to degenerative tears amongst the elderly population. Traumatic meniscus tears typically result from the load-and-shear mechanism in the knee joint. The treatment depends on the size, location, and pattern of the tear. For non-repairable tears, partial or total meniscal resection decreases its tensile stress and increases joint contact stress, thus potentiating the risk of arthritis. A longitudinal vertical tear pattern at the peripheral third red-red zone leads to higher healing potential after repair. The postoperative rehabilitation protocols after repair range from immediate weight-bearing with no range of motion restrictions to non-weight bearing and delayed mobilization for weeks. Pediatric and adolescent patients may require special considerations due to their activity levels, or distinct pathologies such as a discoid meniscus. Further biomechanical and biologic evidence is needed to guide surgical management, postoperative rehabilitation protocols, and future technology applications for traumatic meniscus injuries.

Abstract
Objective To summarize the clinical features, surgical methods, and prognosis of bucket-handle meniscal tears (BHMTs), and provide guidance for clinical treatment. Methods The clinical data of 91 BHMTs patients (91 knees), who met the selection criteria and were admitted between January 2015 and January 2021, was retrospectively analyzed. There were 68 males and 23 females. Age ranged from 16 to 58 years with an average of 34.4 years. The injury was caused by sports in 68 cases, traffic accident in 15 cases, and falls or sprains in 8 cases. There were 49 cases of left knee injury and 42 cases of right knee injury. The time from the onset of symptoms to the admission ranged from 1 day to 13 months (median, 18 days), including >1 month in 35 cases and ≤1 month in 56 cases. Medial BHMTs occurred in 52 cases and lateral BHMTs in 39 cases. There were 36 cases with ACL rupture and 12 cases with discoid meniscus. The knee extension was limited more than 10° in 55 cases. According to the condition of meniscus injury, the meniscus suture with Inside-out combined with All-inside techniques (54 cases) or meniscoplasty (37 cases) under arthroscopy were selected. ACL reconstruction was performed in all patients with ACL rupture with autogenous hamstring tendon. Postoperative complications were observed. International Knee Documentation Committee (IKDC) score, Lysholm score, and Tegner score were used to evaluate knee function, and clinical failure was recorded. Results Two patients developed intermuscular venous thrombosis, which improved after oral anticoagulant therapy. No vascular injury, postoperative infection, joint stiffness, or other complications occurred in all patients. All patients were followed up 24-95 months, with a median of 64 months. A total of 12 cases (13.19%) failed the operation and were re-operated or given oral anti-inflammatory analgesics and rehabilitation therapy. At last follow-up, IKDC score and Lysholm score of 91 patients significantly increased when compared with those before operation ( P<0.05), while Tegner score significantly decreased ( P<0.05). The above indexes of patients treated with meniscus suture and meniscoplasty were also significantly different from those before operation ( P<0.05). Conclusion BHMTs occurs mostly in young men and is one of the important reasons for the limitation of knee extension after trauma. Arthroscopic meniscus suture and meniscoplasty can obtain good effectiveness according to individual conditions of patients. But the latter can better preserve the shape and function of meniscus, and theoretically can obtain better long-term outcomes, which needs to be confirmed by further research with larger sample size.

Differences in postoperative knee function based on concomitant treatment of lateral meniscal injury in the setting of primary ACL reconstruction. BMC Musculoskelet Disord 2023; 24:737. [PMID: 37715148 PMCID: PMC10503181 DOI: 10.1186/s12891-023-06867-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Accepted: 09/08/2023] [Indexed: 09/17/2023] Open
Abstract
BACKGROUND Concomitant lateral meniscal (LM) injuries are common in acute anterior cruciate ligament (ACL) ruptures. However, the effect of addressing these injuries with various treatment methods during primary ACL reconstruction (ACLR) on patient-reported outcomes (PROs) is unknown. Therefore, the purpose of this study was to compare postoperative Knee injury and Osteoarthritis Outcome Score (KOOS) at 2-, 5-, and 10-years after isolated primary ACLR to primary ACLR with various treatment methods to address concomitant LM injury. METHODS This study was based on data from the Swedish National Knee Ligament Registry. Patients ≥ 15 years with data on postoperative KOOS who underwent primary ACLR between the years 2005 and 2018 were included in this study. The study population was divided into five groups: 1) Isolated ACLR, 2) ACLR + LM repair, 3) ACLR + LM resection, 4) ACLR + LM injury left in situ, and 5) ACLR + LM repair + LM resection. Patients with concomitant medial meniscal or other surgically treated ligament injuries were excluded. RESULTS Of 31,819 included patients, 24% had LM injury. After post hoc comparisons, significantly lower scores were found for the KOOS Symptoms subscale in ACLR + LM repair group compared to isolated ACLR (76.0 vs 78.3, p = 0.0097) and ACLR + LM injury left in situ groups (76.0 vs 78.3, p = 0.041) at 2-year follow-up. However, at 10-year follow-up, no differences were found between ACLR + LM repair and isolated ACLR, but ACLR + LM resection resulted in significantly lower KOOS Symptoms scores compared to isolated ACLR (80.4 vs 82.3, p = 0.041). CONCLUSION The results of this study suggest that LM injury during ACLR is associated with lower KOOS scores, particularly in the Symptoms subscale, at short- and long-term follow-up. However, this finding falls below minimal clinical important difference and therefore may not be clinically relevant. LEVEL OF EVIDENCE III.

Abstract
Background The incidence of meniscal tears in children has been increasing. Early sport specialization, more intense training activity, and increasing participation in competitive sports may have affected to that increasing trend. Diagnosing acute menisci tear in children is based on suggestive clinical and magnetic resonance imaging findings. There are special particulars in immature menisci, due to relatively good vascular supply. Furthermore, growing skeleton makes differences in injury pattern, and a clinician needs to recognize not only meniscus but also potential injuries in growth plates and ligaments, which are usual in connection with pediatric meniscus leasion. Clinical and imaging investigation prior to treatment is crucial, because non-operative care is considerable, to achieve spontaneous healing, especially in peripherial tears of younger children. Second, repair is preferred always as possible, in spite of resection due to high rate of long-term sequelae after partial meniscectomy. High standard preoperative imaging aid in preparing to the meniscus sparing arthroscopic intervention. Methods In this current concept article, the clinical considerations of imaging the injured pediatric knee with a suspected meniscus tear and the treatment options by the imaging findings are reviewed.

Abstract
BACKGROUND The incidence of meniscus tears and ACL tears in pediatric patients continues to rise, bringing to question the risk factors associated with these injuries. As meniscus tears are commonly repaired in pediatric populations, the epidemiology of repairable meniscus tears is an important for consideration for surgeons evaluating treatment options. PURPOSE To describe meniscal tear patterns in pediatric and adolescent patients who underwent meniscal repair across multiple institutions and surgeons, as well as to evaluate the relationship between age, sex, and body mass index (BMI) and their effect on the prevalence, type, and displacement of repaired pediatric meniscal tears. STUDY DESIGN Case series; Level of evidence, 4. METHODS Data within a prospective multicenter cohort registry for quality improvement, Sport Cohort Outcome Registry (SCORE), were reviewed to describe repaired meniscal tear patterns. All consecutive arthroscopic meniscal repairs from participating surgeons in patients aged <19 years were analyzed. Tear pattern, location, and displacement were evaluated by patient age, sex, and BMI. A subanalysis was also performed to investigate whether meniscal tear patterns differed between those occurring in isolation or those occurring with a concomitant anterior cruciate ligament (ACL) injury. Analysis of variance was used to generate a multivariate analysis of specified variables. Sex, age, and BMI results were compared across the cohort. RESULTS There were 1185 total meniscal repairs evaluated in as many patients, which included 656 (55.4%) male and 529 (44.6%) female patients. Patients underwent surgery at a mean age of 15.3 years (range, 5-19 years), with a mean BMI of 24.9 (range, 12.3-46.42). Of the 1185 patients, 816 (68.9%) had ACL + meniscal repair and 369 (31.1%) had isolated meniscal repair. The male patients underwent more lateral tear repairs than the female patients (54.3% to 40.9%; P < .001) and had a lower incidence of medial tear repair (32.1% vs 41.4%; P < .001). Patients with repaired lateral tears had a mean age of 15.0 years, compared with a mean age of 15.4 years for patients with repaired medial or bilateral tears (P = .001). Higher BMI was associated with "complex" and "radial" tear repairs of the lateral meniscus (P < .001) but was variable with regard to medial tear repairs. CONCLUSION In pediatric and adolescent populations, the data suggest that the surgical team treating knees with potential meniscal injury should be prepared to encounter more complex meniscal tears, commonly indicated in those with higher BMI, while higher rates of lateral meniscal tears were seen in male and younger patients. Future studies should analyze correlates for meniscal repair survival and outcomes in this pediatric cohort undergoing knee surgery.

Abstract
BACKGROUND Discoid lateral meniscus (DLM) is a rare condition. Patient-reported outcomes using validated instruments are underreported in the literature. DLM outcomes have not been directly compared with nondiscoid meniscus (non-DLM) in adolescent patients. PURPOSE/HYPOTHESIS This study sought to analyze the difference in patient characteristics, surgical treatment, and patient-reported outcomes for adolescent patients arthroscopically treated for symptomatic DLM and non-DLM pathology. We hypothesized that DLM and non-DLM patient-reported outcomes would be similar. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A retrospective review of patients aged <18 years with symptomatic DLM and non-DLM pathology was completed between 2015 and 2021 at a single academic institution. Chart reviews for patient characteristics and surgical operative indications and technique were completed. Patient-reported outcome scores were prospectively collected preoperatively and at 6 months, 1 year, and 2 years after surgery. RESULTS Patients in the DLM group (n = 48), when compared with the non-DLM group (n = 45), were younger (12.71 vs 15.78 years, respectively; P < .001) and had lower body mass index (24.53 vs 28.91, respectively; P < .02). Both groups were majority Hispanic and more commonly male (DLM 65% vs non-DLM 60%). All of the DLM patients had surgery on the lateral discoid meniscus (n = 48), whereas the non-DLM group had surgery on the lateral meniscus (n = 37), medial meniscus (n = 7), or both (n = 1). A majority of patients in both groups underwent meniscal repair (DLM 73% and non-DLM 62%), and there was no difference in surgical treatment between groups (P > .05). A statistically significant improvement was seen in International Knee Documentation Committee (IKDC) and Physical Activity Questionnaire (PAQ) scores from the preoperative assessment to 6 months, 1 year, and 2 years after surgery for both DLM and non-DLM groups (P < .05). No difference was found in scores between DLM and non-DLM groups, between sexes, or between age groups (<13 years or ≥13 years) (P > .05). CONCLUSION Although patients with DLM were younger and had lower body mass index, the IKDC and PAQ scores were not significantly different between the DLM and non-DLM groups. Both groups showed a significant improvement in scores relative to their preoperative scores. Sex and age did not affect IKDC or PAQ scores.

Abstract
The current childhood obesity epidemic, affecting approximately 20% of American children and adolescents, is accompanied by unique orthopedic manifestations. The growing musculoskeletal system is susceptible to the endocrine effects of obesity, resulting in decreased bone mass and quality. As a result, obese children are at increased risk of musculoskeletal injury, fracture, and lower extremity deformities. The efficacy of nonoperative treatment such as casting or bracing may be limited by body habitus and surgical treatment is accompanied by increased risk of perioperative complications.

Abstract
OBJECTIVE The aim of this study was to identify the accuracy of the McMurray test in the adolescent and pediatric population. DESIGN Retrospective case series. SETTING Tertiary care, institutional. PATIENTS Inclusion criteria included patients who presented with unilateral knee pain and were seen by pediatric sports medicine physicians. Patients were excluded if their knee pain was related to any underlying conditions. Three hundred patient charts were reviewed, and 183 patients (age range: 8-18 years, mean: 14 years; 74 male) met the inclusion criteria. INTERVENTIONS Symptoms at initial visit (knee pain). MAIN OUTCOME MEASURES Presence of a meniscal tear using the McMurray test. RESULTS Eighty-four percent (160/191) of patients had a McMurray test documented as performed by the physician, and 17% (27/160) elucidated a positive response. Of 26 patients who had a positive McMurray and underwent magnetic resonance imaging (MRI), 16 (62%) showed a meniscal tear on their MRI. However, of the 87 patients who had a negative McMurray and still underwent MRI, 25 (29%) had a positive meniscal tear. The sensitivity, specificity, positive predictive value, and negative predictive value were 39%, 86%, 62%, and 71%, respectively. CONCLUSION In a pediatric and adolescent population, the McMurray test was negative for 61% (23/38) of meniscal tears identified on MRI. CLINICAL RELEVANCE Although the test can be a useful tool as a part of a thorough evaluation, combining it with mechanical symptoms, patient history and imaging may be more helpful to diagnose a meniscus tear.

The Magnetic Resonance Imaging Pattern of the Lesions Caused by Knee Overuse in the Pediatric Population. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58081107.

Abstract
Background and Objectives: Excessive use of the knee in patients with immature locomotor systems leads to a whole spectrum of morphological changes with possible consequences in adulthood. This study aimed to examine the morphological pattern in magnetic resonance imaging (MRI) that is associated with recurrent pain due to increased physical activity in children. Materials and Methods: This was a retrospective study conducted among pediatric patients treated at the University Children’s Hospital in Belgrade in 2018 and 2019. MRI findings of patients who reported recurrent pain in the knee joint during physical activity and who were without any pathological findings on both clinical examination and knee radiographs were included in the study. Results: MRI findings of 168 patients (73 boys and 95 girls, mean age 14.07 ± 3.34 years) were assessed. Meniscus and cartilage lesions were the most commonly detected morphological findings: meniscus lesions in 49.4%, cartilage ruptures in 44.6%, and cartilage edema in 26.2% of patients. The medial meniscus was more often injured in girls (p = 0.030), while boys were more prone to other joint injuries (p = 0.016), re-injury of the same joint (p = 0.036), bone bruises (p < 0.001), and ligament injuries (p = 0.001). In children older than 15 years, tibial plateau cartilage edema (p = 0.016), chondromalacia patellae (p = 0.005), and retropatellar effusion (p = 0.011) were detected more frequently compared to younger children. Conclusions: Children reporting recurrent knee pain due to increased physical activity, without any detected pathological findings on clinical examination and knee radiography, may have morphological changes that can be detected on MRI. Timely diagnosis of joint lesions should play a significant role in preventing permanent joint dysfunction in the pediatric population as well as in preventing the development of musculoskeletal diseases in adulthood.

Abstract
BACKGROUND The utilization of meniscal repair techniques continues to evolve in an effort to maximize the rate of healing. Meniscal repair outcomes at a minimum of 5 years postoperatively appear to better represent the true failure rates. Thus, a systematic review and meta-analysis of the current literature was conducted to assess the rate of failure at a minimum of 5 years after meniscal repair. METHODS We performed a systematic review of studies reporting the outcomes of meniscal repair at a minimum of 5 years postoperatively. A standardized search and review strategy was utilized. Failure was defined as recurrent clinical symptoms or a meniscal reintervention to repair or resect the meniscus in any capacity, as defined by the study. When reported, outcomes were assessed relative to anterior cruciate ligament (ACL) status, sex, age, and postoperative rehabilitation protocol. Meta-analyses were performed with a random-effects model. RESULTS A total of 27 studies of 1,612 patients and 1,630 meniscal repairs were included in this review and meta-analysis. The pooled overall failure rate was 22.6%, while the failure rate of modern repairs (excluding early-generation all-inside devices) was 19.5%. Medial repairs were significantly more likely to fail compared with lateral repairs (23.9% versus 12.6%, p = 0.04). Failure rates were similar for inside-out (14.2%) and modern all-inside repairs (15.8%). Early-generation all-inside devices had a significantly higher failure rate (30.2%) compared with modern all-inside devices (15.8%, p = 0.01). There was no significant difference in meniscal failure rate between repairs with concomitant ACL reconstruction (21.2%) and repairs in ACL-intact knees (23.3%, p = 0.54). CONCLUSIONS Modern meniscal repair had an overall failure rate of 19.5% at a minimum of 5 years postoperatively. Modern all-inside techniques appear to have improved the success rate of meniscal repair compared with use of early-generation all-inside devices. Lateral repairs were significantly more likely to be successful compared with medial repairs, while no difference was seen between patients undergoing meniscal repair with and without concomitant ACL reconstruction. LEVEL OF EVIDENCE Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Abstract
BACKGROUND Meniscal pathology is commonly encountered in the setting of anterior cruciate ligament (ACL) rupture and is increasingly common in the pediatric and adolescent population. Studies have shown that over half of individuals presenting with ACL rupture will have concurrent meniscal pathology. PURPOSE To define trends in the utilization of meniscal procedures (ie, meniscus repair vs partial meniscectomy) and short-term complications in pediatric and young adult patients with meniscal pathology in the setting of a concurrent ACL reconstruction. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS The IBM MarketScan Commercial Database was utilized to identify ACL reconstruction procedures performed between 2006 and 2018 for individuals aged 5 to 30 years. Annual proportions of meniscectomy and meniscal repair were analyzed, and short-term complications were compared between pediatric/adolescent patients (aged 5-17 years) and young adults (aged 18-30 years). RESULTS An overall 40,736 records of individuals <18 years old with ACL tears were included. The pediatric/adolescent population had a significantly lower proportion of concomitant meniscal procedures (56.8%; 23,149/40,736) than the young adult population (59.7%; 33,764/56,515; P < .01). From 2006 to 2018, utilization of meniscal repair in the setting of ACL reconstruction steadily increased (20.1% to 35.1% [+15 percentage points], P < .01), while the proportion with meniscectomy decreased (34.4% to 21.3% [-13.1 percentage points], P < .01). There was no difference in rate of reoperation for repeat meniscal repair or meniscectomy in the pediatric/adolescent population for those undergoing meniscal repair versus meniscectomy within 180 days of primary surgery (1.7% [188/10,766] vs 1.5% [186/12,383]; P = .14). CONCLUSION From 2006 to 2018, the proportion of patients receiving ACL reconstruction with concomitant meniscal repair increased (20.1% to 35.1%) while the proportion with meniscectomy decreased (34.4% to 21.3%) in the pediatric/adolescent population. Meniscal repair was not associated with a higher 180-day rate of reoperation for repeat meniscal repair or meniscectomy than meniscectomy in the setting of ACL reconstruction.

Abstract
BACKGROUND Injuries to the meniscus root attachments result in extrusion of the meniscus, impaired distribution of hoop stresses, and progressive degenerative articular wear. As a result of these deleterious effects, there has been increasing emphasis on repairing meniscus root injuries to restore structure and function. PURPOSE To describe meniscus root tear patterns, associated injuries, and outcomes of transosseous meniscus root repair in a series of pediatric patients. STUDY DESIGN Case series; Level of evidence, 4. METHODS A single-institution retrospective review approved by the institutional review board was performed on consecutive adolescent patients aged <19 years with a meniscus posterior root tear treated with transosseous root repair over 4 years. All patients had a minimum 24-month clinical follow-up. The primary outcomes were revision meniscal surgery, and Lysholm, patient satisfaction, and Tegner activity scores. RESULTS A total of 20 patients (11 male and 9 female patients), with a mean age of 15.6 years (range, 13-18 years), met the inclusion criteria. There were 14 lateral meniscus root tears and 6 medial meniscus root tears. Seventeen patients (85%) had an associated ligament tear: 12 anterior cruciate ligament (ACL) tears and 5 posterior cruciate ligament tears. Two root tears occurred in isolation and both were the posterior root of the medial meniscus. The majority of meniscus root tears (n = 14 patients; 70%) were root avulsions (type 5). The mean follow-up was 42 months (range, 25-71 months). One patient underwent secondary surgery on the affected meniscus after a new injury 4 years postoperatively. Patient-reported outcomes were obtained for 16 patients (80%) at a mean 54-month follow-up. The median Lysholm score was 95 (interquartile range [IQR], 90-100). The median patient satisfaction score was 10 (IQR, 8-10). Thirteen of 16 patients (81%) reported returning to the same or higher level of sports after surgery. CONCLUSION Meniscus root tears most commonly occur in pediatric patients as root avulsions of the posterior root of the lateral meniscus and in association with ACL tears. This is unique compared with the adult population, in which the medial meniscus posterior root is often injured in isolation from a radial tear adjacent to the root. In our pediatric case series, transosseous root repair resulted in successful outcomes in the majority of patients, with durable results at the midterm follow-up.

Abstract
Orthopedic sports surgery of the knee and shoulder is generally considered to be safe and effective. Vascular complications can occur during or after arthroscopy of either joint. A thorough understanding of anatomy, particularly when placing portals in non-routine locations, is extremely important. Prompt recognition of any vascular complication is of significant importance. This review will discuss the potential vascular complications for both knee and shoulder sports surgery, review the relevant anatomy, and discuss the treatment and expected outcome of each.

Abstract
The prevalence of isolated meniscal injuries in children and adolescents is low; however, we see an increase mainly due to intensified sports-related activities at an early age. A meniscal repair should be attempted whenever possible as children present with increased meniscal healing potential. The diagnosis and management of meniscal tears involve both patient factors and tear characteristics: size, anatomical location and associated injuries. Special attention should be given to the feature of discoid menisci and related tears as they require a specific management plan. This state-of-the-art review highlights the most recent studies on clinical evaluation, surgical techniques, tips and tricks, pitfalls, outcomes, return-to-sports, geographical differences and future perspectives related to meniscal injuries in children and adolescents.

Abstract
BACKGROUND Discoid meniscus, a congenital meniscus variant, may have greater incidence in Asian populations. No US population-based studies have examined the discoid meniscus ethnic/racial distribution. In pediatric patients undergoing meniscus surgery, it is hypothesized that ethnic/racial variability exists in patients with discoid meniscus and this variability is different than in patients with medial meniscus tears. METHODS The Pediatric Health Information System was queried from 48 hospitals to examine patients 18 years of age and younger between 2015 and 2019, using International Classification of Diseases, 10th Revision, Clinical Modification codes. A cohort of patients treated surgically for discoid meniscus was compared with a cohort of patients treated surgically for medial meniscal tear. These 2 populations were compared based on age, sex, ethnicity/race, Current Procedural Terminology code, insurance, urban versus rural, and region of country. Univariate testing and multivariable logistic modeling were used to test for associations. RESULTS A discoid meniscus cohort of 399 children (median age, 13.0 y) was compared with a medial meniscus tear cohort of 3157 children (median age, 16.0 y) (P<0.001). Hispanic/Latino children accounted for 36.8% of the discoid lateral meniscus and 22.7% of the medial meniscus populations (P<0.001). Among pediatric patients that had surgery for discoid lateral meniscus or medial meniscus, Hispanic/Latino children had 2.36 times the odds of surgery for discoid meniscus compared with White patients after adjusting for age and insurance (P<0.001). Asian children also had 2.41 times the odds of surgery for discoid meniscus compared with White patients (P=0.017). CONCLUSIONS This study shows a significant association of ethnicity/race with discoid versus medial meniscus surgical treatment in children. Among pediatric patients undergoing surgery for discoid meniscus, Hispanic/Latino and Asian patients were a significantly larger percentage of the population than White patients. Hispanic/Latino children made up a greater percentage of the population having surgery for a torn discoid meniscus versus a torn medial mensicus. When evaluating pediatric patients, younger age and Asian or Hispanic/Latino ethnicity should increase attention to the possibility of a discoid meniscus. LEVEL OF EVIDENCE Level IV.

Abstract
INTRODUCTION We report a relatively rare case of partial-thickness radial tear in the inferior surface of lateral meniscus, while the superior surface is intact. This situation was similar to PASTA rotator cuff tear. Meanwhile, there is a full-thickness radial tear in the edge. CASE PRESENTATION A 17-year-old boy twisted the left knee while playing basketball. Magnetic resonance imaging (MRI) revealed radial tear of the lateral meniscus. During arthroscopy, it was found that there was a full-thickness radial tear of about 2 mm located in the edge. Partial meniscectomy was performed to treat radial meniscal tear located in the white area. After that, we found that the superior surface of the lateral meniscus was intact. However, in the inferior surface of the lateral meniscus, partial-thickness radial tear was found extending to red zone. We used FASTFIX (Smith & Nephew) for all-inside suture. As of three months after this surgery, the patient recovered smoothly. DISCUSSION Suspect that the force acts on a special position of meniscus and the thickness of the meniscus is uneven. Thus, it leads to partial-thickness radial tear in the inferior-surface, while the superior surface is intact. CONCLUSION Partial-thickness radial tears in the inferior surface of lateral meniscus are relatively rare. This situation was similar to PASTA rotator cuff tear. Because the superior surface of the meniscus is intact, it may results in misdiagnosis. It's easy to ignore the inferior surface injury.

Rates of Concomitant Meniscal Tears in Pediatric Patients With Anterior Cruciate Ligament Injuries Increase With Age and Body Mass Index. Orthop J Sports Med 2021; 9:2325967120986565. [PMID: 33796585 PMCID: PMC7968031 DOI: 10.1177/2325967120986565] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Accepted: 09/25/2020] [Indexed: 01/12/2023] Open
Abstract
Background Anterior cruciate ligament (ACL) tears are frequently associated with meniscal injury. Risk factors for concomitant meniscal injuries have been studied in the adult population but less so in pediatric patients. Purpose To evaluate the relationship between age and body mass index (BMI) and the presence of a concomitant meniscal tear at the time of ACL reconstruction (ACLR) in pediatric patients. Study Design Case-control study; Level of evidence, 3. Methods A single-institution retrospective review was performed of patients aged <19 years who underwent primary ACLR over a 3.5-year period. Revision ACLR and multiligament knee reconstructions were excluded. Logistic regression was used to identify risk factors associated with having a meniscal tear at the time of surgery. Subgroup analysis was performed for medial and lateral meniscal tears. Results Included in this study were 453 patients (230 males, 223 females; median age, 15 years). Of these, 265 patients (58%) had a meniscal tear, including 150 isolated lateral meniscal tears, 53 isolated medial meniscal tears, and 62 patients with both lateral and medial meniscal tears. Median time from injury to surgery was 48 days. For every 1-year increase in age, there was a 16% increase in the adjusted odds of having any meniscal tear (odds ratio [OR], 1.16; 95% confidence interval [CI], 1.05-1.27; P = .002), with a 20% increase in the odds of having a medial meniscal tear (OR, 1.20; 95% CI, 1.07-1.35; P = .002) and a 16% increase in the odds of having a lateral meniscal tear (OR, 1.16; 95% CI, 1.05-1.27; P = .003). For every 2-point increase in BMI, there was a 12% increase in the odds of having any meniscal tear (OR, 1.12; 95% CI, 1.02-1.22; P = .016) and a 10% increase in the odds of having a lateral meniscal tear (OR, 1.10; 95% CI, 1.01-1.19; P = .028). Conclusion Pediatric patients undergoing ACLR had a 58% incidence of concomitant meniscal pathology. Increasing age and BMI were independent risk factors for these injuries, while no association was found between time to surgery and meniscal pathology.

Different effects of the lateral meniscus complete radial tear on the load distribution and transmission functions depending on the tear site. Knee Surg Sports Traumatol Arthrosc 2021; 29:342-351. [PMID: 32152692 DOI: 10.1007/s00167-020-05915-8] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2019] [Accepted: 02/24/2020] [Indexed: 01/13/2023]
Abstract
PURPOSE To compare the effect of the lateral meniscus (LM) complete radial tear at different tear sites on the load distribution and transmission functions. METHODS A compressive load of 300 N was applied to the intact porcine knees (n = 30) at 15°, 30°, 60°, 90°, and 120° of flexion. The LM complete radial tears were created at the middle portion (group M), the posterior portion (group P), or the posterior root (group R) (n = 10, each group), and the same loading procedure was followed. Finally, the recorded three-dimensional paths were reproduced on the LM-removed knees. The peak contact pressure (contact area) in the lateral compartment and the calculated in situ force of the LM under the principle of superposition were compared among the four groups (intact, group M, group P, and group R). RESULTS At all the flexion angles, the peak contact pressure (contact area) was significantly higher (lower) after creating the LM complete radial tear as compared to that in the intact state (p < 0.01). At 120° of flexion, group R represented the highest peak contact pressure (lowest contact area), followed by group P and group M (p < 0.05). The results of the in situ force carried by the LM were similar to those of the tibiofemoral contact mechanics. CONCLUSION The detrimental effect of the LM complete radial tear on the load distribution and transmission functions was greatest in the posterior root tear, followed by the posterior portion tear and the middle portion tear in the deep-flexed position. Complete radial tars of the meniscus, especially at the posterior root, should be repaired to restore the biomechanical function.

Abstract
PURPOSE The purpose of this study was to evaluate the effectiveness of three constructs and techniques for repair of radial tears of the meniscus. METHODS Thirty fresh frozen porcine menisci were divided equally into three groups consisting of (1) inside-out repair group, (2) a commonly used all-inside suture with anchor hybrid repair construct (AISAH) (Meniscal Cinch™), and (3) an all-inside all-suture repair construct (AIAS) (Knee Scorpion™). Radial tears were created and repaired and then the menisci were secured to the materials testing machine. Both cyclic loading and load-to-failure testing were performed. The displacement, stiffness, response to cyclic loading, and mode of failure were recorded and analyzed statistically. RESULTS The displacement after cyclic loading (DACL) of the Cinch repair construct group was significantly higher than that of the inside-out repair construct group (p = 0.000) and AIAS repair construct (p = 0.000). There was not a statistical difference of DACL between inside-out and AIAS groups (n.s.). The inside-out construct failed at a significantly higher load than the AISAH repair construct (p = 0.000) and AIAS construct (p = 0.006). The AIAS construct failed at a significantly higher load than the AISAH repair construct (p = 0.009). The AIAS had a higher stiffness than AISAH (p = 0.047). The AIAS had a higher load at 3 mm protrusion than AISAH (p = 0.034). CONCLUSION The AIAS repair construct had better biomechanical behaviors than AISAH construct and inside-out repair technique. Inside-out sutures and AIAS repair construct had similar biomechanical responses to cyclic loading. The AIAS can be used for meniscus tear surgical repair with less damage to peri-meniscus tissues.

Abstract
If not treated adequately, the knee injuries in adolescents can cause long-term functional impairments. The aim of our study was to quantify the functioning capacity in children who suffered soft tissues and/or bone lesions of the knee treated by arthroscopy. We reviewed the medical charts of 5 adolescent patients diagnosed with sport knees injuries, admitted in our clinic in the last two years. Arthroscopy was made three weeks after the injury. Afterwards, they were addressed to the Rehabilitation Department and followed the physical exercise programme. The patients were assessed at the beginning of rehabilitation and after 3 months: knee ROM (flexion and extension deficit) and International Knee Documentation Committee (IKDC) subjective evaluation. At the final assessment all patients presented significantly improvements in knee range of motion and functional capacity. Arthroscopic surgery, followed by a tailored rehabilitation programme, is important in the management of adolescents with knee injuries.

Abstract
Meniscal root tears have become increasingly recognized in the past decade. Lateral meniscus root tears typically occur in active, younger patients who sustain acute anterior cruciate ligament tears. Conversely, medial meniscus root tears typically occur in isolation and affect middle-aged patients. However, recent reports have described the incidence of meniscal root tears occurring in pediatric populations who are skeletally immature. The purpose of this technical note is to describe the authors' surgical technique for medial meniscal root repair for patients with open physes.

J Orthop Res 2020; 38:1268-1278.

Abstract
While there is emerging data on how duration of symptoms prior to surgery relates to outcomes of patients undergoing arthroscopic partial meniscectomy, little is known about how duration of symptoms relates to the biology of the knee in these patients. The purpose of this study was to test the hypothesis that duration of symptoms prior to arthroscopic partial meniscectomy is associated with expression of osteoarthritis (OA)-related genes in the meniscus. We collected resected meniscus from patients (N = 76) undergoing clinically indicated arthroscopic partial meniscectomy from knees without advanced degenerative changes. RNA from 64 patients was analyzed for 28 candidate OA transcripts by real-time polymerase chain reaction (PCR). RNA was also probed for identification of novel genes by RNA microarray in 12 patients followed by validation of selected candidates by real-time PCR. The association of gene expression with duration of symptoms prior to surgery was tested. Additional screening was performed with known OA genetic risk alleles assembled from published literature and with gene transcripts differentially expressed between non-OA and OA cartilage and menisci. Our data revealed that duration of symptoms did not predict expression of OA genes in the meniscus, other than limited association with CXCL3, BMP2, and HLA-DQA1. Microarray identified new genes and pathways with unknown role(s) in meniscus injury and OA and validation of a subset of genes by real-time PCR showed expression pattern highly concordant with the microarray data. While duration of symptoms prior to arthroscopic partial meniscectomy does not significantly alter the expression of OA related genes, the association with novel genes and pathways deserves further investigation.

Abstract
Meniscus injuries affect the young and physically active population. Although meniscus injuries are common in many sports, football, soccer, basketball, and wrestling are associated with the greatest risk. In an occupational setting, jobs requiring kneeling, squatting, and increased physical activity level have the greatest risk. Meniscus injury can be isolated to the meniscus or associated with other concomitant injuries, including anterior cruciate ligament tears and tibial plateau fractures. The frequency of meniscal repair is increasing because of a better understanding of meniscal pathophysiology, technological advancements, and a focus on meniscal preservation following injury to mitigate long-term consequences such as osteoarthritis.

Abstract
PURPOSE The importance of meniscus integrity in the prevention of early osteoarthritis is well known, and preservation is accepted as the primary goal. The purpose of the ESSKA (European Society for Sports Traumatology, Knee Surgery and Arthroscopy) European consensus on traumatic meniscus tears was to provide recommendations for the treatment of meniscus tears based on both scientific evidence and the clinical experience of knee experts. METHODS Three groups of surgeons and scientists elaborated and ratified the so-called formal consensus process to define the recommendations for the management of traumatic meniscus tears. A traumatic meniscus tear was defined as a tear with an acute onset of symptoms caused by a sufficient trauma. The expert groups included a steering group of eight European surgeons and scientists, a rating group of another nineteen European surgeons, and a peer review group. The steering group prepared twenty-seven question and answer sets based on the scientific literature. The quality of the answers received grades of A (a high level of scientific support), B (scientific presumption), C (a low level of scientific support) or D (expert opinion). These question and answer sets were then submitted to and evaluated by the rating group. All answers were scored from 1 (= totally inappropriate) to 9 (= totally appropriate) points. Thereafter, the comments of the members of the rating group were incorporated by the steering group and the consensus was submitted to the rating group a second time. Once a general consensus was reached between the steering and rating groups, the finalized question and answer sets were submitted for final review by the peer review group composed of representatives of the ESSKA-affiliated national societies. Eighteen representatives replied. RESULTS The review of the literature revealed a rather low scientific quality of studies examining the treatment of traumatic meniscus tears. Of the 27 questions, only one question received a grade of A (a high level of scientific support), and another received a grade of B (scientific presumption). The remaining questions received grades of C and D. The mean rating of all questions by the rating group was 8.2 (95% confidence interval 8.1-8.4). A general agreement that MRI should be performed on a systematic basis was not achieved. However, MRI was recommended when arthroscopy would be considered to identify concomitant pathologies. In this case, the indication for MRI should be determined by a musculoskeletal specialist. Based on our data, stable left in situ lateral meniscus tears appear to show a better prognosis than medial tears. When repair is required, surgery should be performed as early as possible. Evidence that biological enhancement such as needling or the application of platelet-rich plasma would improve healing was not identified. Preservation of the meniscus should be considered as the first line of treatment because of an inferior clinical and radiological long-term outcome after partial meniscectomy compared to meniscus repair. DISCUSSION The consensus was generated to present the best possible recommendations for the treatment of traumatic meniscus tears and provides some groundwork for a clinical decision-making process regarding the treatment of meniscus tears. Preservation of the meniscus should be the first line of treatment when possible, because the clinical and radiological long-term outcomes are worse after partial meniscectomy than after meniscus preservation. The consensus clearly states that numerous meniscus tears that were considered irreparable should be repaired, e.g., older tears, tears in obese patients, long tears, etc. LEVEL OF EVIDENCE: II.

Abstract
Background: The close proximity of the popliteal neurovascular bundle to the posterior
horn of the lateral meniscus puts it at risk of compromise during lateral
meniscal repair. This is particularly important in smaller pediatric
patients, who are commonly treated for lateral meniscal abnormalities in
isolation (discoid meniscus) or concomitantly with anterior cruciate
ligament reconstruction. Purpose: To quantify the distance between the posterior horn of the lateral meniscus
and the popliteal neurovascular bundle along the path of meniscal repair and
to investigate for associations with age, sex, height, weight, body mass
index (BMI), and skeletal maturity. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 144 magnetic resonance imaging scans were evaluated in a cohort of
patients aged 10 to 18 years without meniscal or ligament abnormalities.
Measurements were made along a line from the anterolateral portal between
the popliteal neurovascular bundle and the free edge, midpoint, and
meniscocapsular junctions of the posterior horn of the lateral meniscus. In
addition to descriptive statistics of these distances by age and sex,
analyses of variance and linear regression analyses were performed to
investigate for associations with age, sex, height, weight, BMI, and
skeletal maturity. Results: Male participants had a significantly larger mean free edge distance (14.4 ±
2.5 vs 13.1 ± 2.5 mm, respectively; P = .005) and midpoint
distance (9.6 ± 2.2 vs 8.9 ± 1.8 mm, respectively; P =
.011) than female participants but not a significantly larger
meniscocapsular distance (5.2 ± 1.6 vs 4.6 ± 1.4 mm, respectively;
P = .096). Linear regression analyses revealed
significant associations between these distances and age, height, weight,
and BMI (P < .001 for all). There were statistically
significant pairwise differences for free edge and midpoint distances to the
neurovascular bundle between patients with open and closed physes. Conclusion: The distance between the posterior horn of the lateral meniscus and the
popliteal vasculature along a trajectory from the standard anterolateral
arthroscopic portal increases linearly throughout development between the
ages of 10 and 18 years. There were also significant associations between
height, weight, BMI, and skeletal maturity and these anatomic distances.
Knowing the safe distance to the popliteal vasculature will increase the
safety of arthroscopic lateral meniscal repair in children, especially with
all-inside devices that require setting the penetration depth for the
advancement of a sharp delivery device beyond the posterior capsule.

Abstract
BACKGROUND In order to determine whether treatments are effective in the treatment of meniscus tears, it is first necessary to understand the natural history of meniscus tears. The purpose of this paper is to review the literature to ascertain the natural history of meniscus tears in children and adolescents. METHODS A search of the Pubmed and Embase databases was performed using the search terms "meniscus tears," "natural history of meniscus tears," "knee meniscus," "discoid meniscus," and "natural history of discoid meniscus tears." RESULTS A total of 2567 articles on meniscus tears, 28 articles on natural history of meniscus tears, 8065 articles on "menisci," 396 articles on "discoid meniscus," and only 2 on the "natural history of discoid meniscus" were found. After reviewing the titles of these articles and reviewing the abstracts of 237 articles, it was clear that there was little true long-term natural history data of untreated meniscus tears nor whether treating meniscus tears altered the natural history. Twenty-five articles were chosen as there was some mention of natural history in their studies. CONCLUSIONS There are few long-term data on untreated meniscal tears or discoid meniscus, or tears in children and adolescents. The literature suggests that there is a higher incidence of chondral injury and subsequent osteoarthritis, but there are many confounding variables which are not controlled for in these relatively short-term papers.

Abstract
Background: Bucket-handle meniscal tears (BHMTs), which we define as vertical
longitudinal tears of the meniscus with displacement of the torn inner
fragment toward the intercondylar notch region, are a well-recognized tear
pattern. Optimizing the management of BHMTs in younger patients is
important, as preserving meniscal tissue may limit future joint
degeneration. Purpose/Hypothesis: The purpose of this study was to review the patient demographics, clinical
presentation, operative details, outcomes, and risk factors for a
reoperation associated with operatively treated BHMTs in a pediatric
population. We hypothesized that the repair of BHMTs in adolescents would
yield a higher reoperation rate than meniscectomy in our population. Study Design: Case-series; Level of evidence, 4. Methods: A departmental database was queried to identify all patients 19 years or
younger who presented with a BHMT and underwent surgery between October 2002
and February 2013. Clinical, radiological, and surgical data were
retrospectively collected, and risk factors for a reoperation and persistent
pain were assessed in all patients with longer than or equal to 6 months of
follow-up. Results: A total of 280 BHMTs were treated arthroscopically by 1 of 8 sports medicine
fellowship–trained surgeons. The mean age at surgery was 15.5 ± 2.5 years
(range, 2.1-19.2 years), and most patients were male (177/280; 63%). Most
injuries occurred during sports (203/248; 82%) and involved the medial
meniscus (157/280; 56%). Concurrent anterior cruciate ligament (ACL) surgery
was performed in 103 cases (37%). Meniscal repair was performed in 181 cases
(65%) and was more common in younger patients (P = .01) and
for the lateral meniscus (P < .001). Among 185 (66%)
cases with longer than or equal to 6 months of adequate follow-up data
(which included 126 meniscal repairs [68%]), a meniscus-related reoperation
occurred in 45 (24%) cases. A reoperation related to the original BHMT
injury or surgery was more common after meniscal repair than after
meniscectomy (40/126 [32%] vs 5/59 [8%], respectively) (P =
.001) and less common with concurrent ACL surgery (P =
.07), although this was not statistically significant. Among patients
injured during sports and with adequate follow-up, all but 1 patient
(176/177; 99%) returned to sports; a slower rate of return was seen in those
undergoing meniscal repair (P = .002) and concurrent ACL
surgery (P < .001). At final follow-up, 170 of 185
patients (92%) were pain free. For the 15 patients with persistent pain at
final follow-up, no identifiable risk factors for persistent pain were
identified. Conclusion: Most BHMTs in younger patients occurred in males and during sports and
affected the medial meniscus. Concurrent ACL surgery was indicated in
approximately one-third of cases and was associated with a lower reoperation
rate and slower return to sports. Two-thirds of patients underwent meniscal
repair, over two-thirds of whom did not require a reoperation during the
study period, despite the high activity levels in this age group.

Abstract
CONTEXT: Meniscal injuries are common among both sport- and non-sport-related injuries, with over 1.7 million meniscal surgeries performed worldwide every year. As meniscal surgeries become more common, so does meniscal allograft transplantation (MAT). However, little is known about the outcomes of MAT in active patients who desire to go back to preinjury activities. OBJECTIVE: The purpose of this systematic review and meta-analysis was to evaluate return to sport, clinical outcome, and complications after MAT in sport-active patients. DATA SOURCES: A systematic search of MEDLINE, EMBASE, and CINAHL electronic databases was performed on February 25, 2018. STUDY SELECTION: Studies of level 1 through 4 evidence looking at MAT in physically active patients with reported return to activity outcomes and at least 2-year follow-up were included. STUDY DESIGN: Systematic review and meta-analysis. LEVEL OF EVIDENCE: Level 4. DATA EXTRACTION: Details of sport-related outcomes and reoperations were extracted and pooled in a meta-analysis. RESULTS: Nine studies were included in this systematic review. A majority (77%) of athletes and physically active patients were able to return to sport after MAT; two-thirds were able to perform at preinjury levels. Graft-related reoperations were reported in 13% of patients, while the joint replacement rate with partial or total knee prosthesis was 1.2%. CONCLUSION: Physical activity after MAT appears possible, especially for low-impact sports. However, because of the limited number of studies, their low quality, and the short-term follow-up, the participation recommendation for high-impact and strenuous activities should be considered with caution until high-quality evidence of long-term safety becomes available.

Abstract
Obese pediatric patients that incur an anterior cruciate ligament tear have an increased risk of an irreparable meniscal tear. Nevertheless, these patients should be treated the same as normal weight patients because they can do very well with standard anterior cruciate ligament reconstruction techniques and appropriate postoperative physical therapy as well as a delayed return to sports of at least 9 months. Obesity is an ever-increasing issue in the United States. Further work should be done to stem the rise of obesity because 1 consequence is a deleterious effect on meniscal tissue when a ligamentous knee injury occurs.

Abstract
Background Despite the increasing incidence of sports-related knee injuries in youth athletes, few studies have reported on the diagnosis and treatment of pediatric and adolescent meniscal root injuries. Purpose To describe traumatic posterior meniscal root injuries in a pediatric and adolescent population and compare the presentation of meniscal root injuries versus that of nonroot injuries. Study Design Cohort study; Level of evidence, 3. Methods A study was conducted of all knee arthroscopies performed on consecutive patients treated in a pediatric sports practice from March 2012 through February 2015. All patients who were younger than 20 years at the time of their injury and who underwent an arthroscopy with meniscal injury were included. Patients with discoid lateral meniscus, atraumatic meniscal cysts, partial-thickness meniscal root injuries (LaPrade type 1), and recurrent root tears were excluded. A comparative analysis of root and nonroot injuries was performed. Results A total of 314 patients had surgery for meniscal injury (mean patient age, 16.0 years; range, 10.5-19.6 years). Of these patients, 58 (18.5%) posterior meniscal root injuries were identified. The root injuries were more likely to have joint line tenderness on preliminary physical examination compared with nonroot injuries (96.5% vs 58.6%, respectively; P < .001). Root injuries rarely occurred in isolation compared with nonroot meniscal tears (6.9% vs 17.6%; P = .021) and were frequently treated in combination with anterior cruciate ligament (ACL) injuries (86.2%). Lateral root injuries occurred more often in conjunction with ACL injuries compared with medial root injuries (84.8% vs 22.2%; P < .001). On review of preoperative imaging, meniscal extrusion occurred more often in root injuries than in nonroot injuries (32.8% vs 3.5%; P < .0001) and was uncommonly seen in the skeletally immature patient. Extrusion was seen more often in medial than lateral root tears (66.7% vs 21.7%; P = .008). A majority of patients (57/58) underwent transosseous suture repair of the meniscal root. Conclusion When treating a pediatric or adolescent patient for a traumatic meniscal tear, a surgeon may expect to see a posterior meniscal root injury in as many as 1 in 6 patients. When treated for an ACL, contact, or multiligament injury or meniscal extrusion, a pediatric or adolescent patient may demonstrate a meniscal root avulsion or complex meniscal tear. These data provide practitioners with an improved ability to identify and treat meniscal root injuries that otherwise lead to rapid cartilage degeneration.

Abstract
Tears are central to knee meniscus pathology and, from a mechanical perspective, are crack-like defects (cracks). In many materials, cracks create stress concentrations that cause progressive local rupture and reduce effective strength. It is currently unknown if cracks in meniscus have these consequences; if they do, this would have repercussions for management of meniscus pathology. The objective of this study was to determine if a short crack in meniscus tissue, which mimics a preclinical meniscus tear, (a) causes crack growth and reduces effective strength, (b) creates a near-tip strain concentration and (c) creates unloaded regions on either side of the crack. Specimens with and without cracks were tested in uniaxial tension and compared in terms of macroscopic stress-strain curves and digital image correlation strain fields. The strain fields were used as an indicator of stress concentrations and unloaded regions. Effective strength was found to be insensitive to the presence of a crack (potential effect < 0.86 s.d.; β = 0.2), but significant strain concentrations, which have the potential to lead to long-term accumulation of tissue or cell damage, were observed near the crack tip.

Abstract
Context: With the rise in sports participation and increased athleticism in the
adolescent population, there is an ever-growing need to better understand
adolescent meniscus pathology and treatment. Objective: To better understand the operative management of meniscus tears in the
adolescent population. Data Sources: A systematic review of PubMed (MEDLINE) and Google Scholar was performed for
all archived years. Study Selection: Studies that reported on isolated meniscus tears in adolescent patients (age,
10-19 years) were included. Study Design: Systematic review and meta-analysis. Level of Evidence: Level 4. Data Extraction: Two authors reviewed and extracted data from studies that fulfilled all
inclusion criteria. Results: Nine studies on isolated meniscus tears in adolescent patients were found,
with level of evidence ranging from 3 to 4. These studies evaluated a total
of 373 patients (248 males, 125 females) and 390 knees. Seven studies were
published between 1979 and 2000, all of which discuss meniscectomy as the
primary treatment. Two studies were published after 2000 and report on
meniscus repair surgery. The mean patient age was 14.4 years. A total of 308
meniscectomies and 64 meniscus repairs were performed. Follow-up ranged from
1.8 to 30 years (mean, 10.8 years). A 37% retear rate was reported for
patients undergoing meniscus repair. Different outcome measures were used
for meniscectomy versus meniscus repair. Three studies evaluating
meniscectomy reported Tapper-Hoover scores, showing 54 patients with an
excellent result, 58 with good, 57 with fair, and 23 with poor results. Conclusion: A shift in the management of isolated adolescent meniscal tears is reflected
in the literature, with a recent increase in operative repair. This is
likely secondary to poor outcomes after meniscectomy reflected in long-term
follow-up studies. The current literature highlights the need for improved
description of tear patterns, standardized reporting of outcome measures,
and improved study methodologies to help guide orthopaedic surgeons on
operative treatment of meniscal tears in adolescent patients.

Abstract
PURPOSE To develop prediction models to improve the diagnostic utility of plain radiographs for the diagnosis of complete discoid lateral meniscus by combining previously reported radiographic findings. METHODS Patients ages 5 to 16 years with complete discoid lateral meniscus confirmed by arthroscopy or magnetic resonance imaging were included. Patients with insufficient radiographs were excluded. Normal control subjects were randomly sampled by age and sex matching. Subjects were divided into 2 groups considering skeletal maturation (5-9 and 10-16 years). Radiographic variables included were lateral joint space, height of the fibular head, height of the lateral tibial spine, obliquity and cupping of the lateral tibial plateau, condylar cutoff sign, and squaring and notching of the lateral femoral condyle. Prediction models were developed by regression analyses. The cutoff value (COV) for best accuracy was determined with its sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). RESULTS A total of 162 knees (126 patients) with complete discoid lateral meniscus and 151 age- and sex-matched knees (151 subjects) with normal meniscus were included. In subjects 5 to 9 years old, the prediction model was risk score = [-20.08 * height of the fibular head/femoral interepicondylar distance (FIED)] + [-42.26 * height of the lateral tibial spine/FIED]. The COV of -8.47 showed the best accuracy (74.4%), with sensitivity of 85.9%; specificity, 60.4%; PPV, 72.4%; and NPV, 78.0%. In subjects 10 to 16 years old, the prediction model was risk score = [77.04 * lateral joint space/FIED] + [-34.55 * height of the fibular head/FIED] + [-56.58 * height of the lateral tibial spine/FIED] + [-16.44 * condylar cutoff sign]. The COV of -18.03 showed the best accuracy (85.4%), with sensitivity of 79.6%; specificity, 90.4%; PPV, 87.6%; and NPV, 83.9%. CONCLUSIONS The prediction models combining the plain radiographic findings showed higher diagnostic values than the diagnostic values of the individual radiographic findings. The results of this study provide improved diagnostic utility of plain radiography for the detection of completed discoid lateral meniscus in children. LEVEL OF EVIDENCE Level III, diagnostic study.

Abstract
BACKGROUND Meniscus tears in the young patient are becoming more prevalent. Knowledge of presenting characteristics and morphology can affect treatment decisions. The purpose of this study was to review and evaluate all the isolated lateral meniscus pathology that required arthroscopic treatment in a pediatric sports medicine practice and compare presenting characteristics between those with a discoid meniscus and those with normal meniscal morphology. METHODS We performed a retrospective review of all isolated lateral meniscus arthroscopic procedures from 2003 to 2012 in a high-volume pediatric sports practice. Presentation, radiographs, and intraoperative findings were reviewed. The prevalence and clinical findings of a discoid meniscus in this population and among all age groups were compared with those with a meniscus tear occurring in a normal meniscus. RESULTS Two hundred and sixty-one arthroscopies were performed for symptomatic isolated lateral menisci pathology. Of these, 75% were discoid in nature; the remainder was tears occurring in normal menisci. Ninety-six of 99 patients (97%) with lateral meniscus pathology under the age of 13 had a discoid meniscus and 66% presented with no injury. There was a transition within the population at 14 years of age, with a rise in the incidence of normal meniscal body tears. Even after this transition point, meniscal pathology incidence remained notable; 59% of isolated lateral meniscus pathology in patients between the ages of 14 and 16 years old were a discoid meniscus. Magnetic resonance imaging criteria for discoid meniscus (3 consecutive sagittal cuts or coronal mid-compartment measure) were unreliable after the age of 13 years old. The ratio of complete to incomplete discoids in all age groups was 4 to 3. CONCLUSIONS In conclusion, discoid menisci have a high prevalence in isolated lateral meniscus pathology requiring knee arthroscopy. Clinical presentation, imaging, characteristics, and treatment may be different among different age groups. In the adolescent age group (14 to 16 y old), the presentation of a discoid meniscus may not be different from a meniscus tear with normal morphology. LEVEL OF EVIDENCE Level III-diagnostic.

Abstract
BACKGROUND Partial meniscectomy does not consistently produce the desired positive outcomes intended for meniscal tears lesions; therefore, a need exists for research into alternatives for treating symptoms of meniscal tears. The purpose of this case series was to examine the effect of the Mulligan Concept (MC) "Squeeze" technique in physically active participants who presented with clinical symptoms of meniscal tears. DESCRIPTION OF CASES The MC "Squeeze" technique was applied in five cases of clinically diagnosed meniscal tears in a physically active population. The Numeric Pain Rating Scale (NRS), the Patient Specific Functional Scale (PSFS), the Disability in the Physically Active (DPA) Scale, and the Knee injury and Osteoarthritis Outcomes Score (KOOS) were administered to assess participant pain level and function. OUTCOMES Statistically significant improvements were found on cumulative NRS (p ≤ 0.001), current NRS (p ≤ 0.002), PSFS (p ≤ 0.003), DPA (p ≤ 0.019), and KOOS (p ≤ 0.002) scores across all five participants. All participants exceeded the minimal clinically important difference (MCID) on the first treatment and reported an NRS score and current pain score of one point or less at discharge. The MC "Squeeze" technique produced statistically and clinically significant changes across all outcome measures in all five participants. DISCUSSION The use of the MC "Squeeze" technique in this case series indicated positive outcomes in five participants who presented with meniscal tear symptoms. Of importance to the athletic population, each of the participants continued to engage in sport activity as tolerated unless otherwise required during the treatment period. The outcomes reported in this case series exceed those reported when using traditional conservative therapy and the return to play timelines for meniscal tears treated with partial meniscectomies.

Abstract
BACKGROUND A flipped, or inverted, meniscus segment is easily visualized in the normal meniscus. However, an inverted discoid meniscus segment may be difficult to appreciate because the tear occurs more centrally and leaves more meniscal rim; thus, it may be undertreated if not addressed during arthroscopy. PURPOSE To describe findings on clinical history, radiographs, MRI, and arthroscopy of a lateral discoid meniscus with an inverted segment and compare them with characteristics of a lateral discoid meniscus without an inverted segment. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Between 2009 and 2012, a retrospective series of 121 consecutive knee arthroscopies for symptomatic lateral discoid meniscus were reviewed for the presence of an inverted fragment. Chart review of clinical presentation, operative reports, radiographic images, and arthroscopic images was performed. Comparative analysis of the clinical presentation between lateral discoid menisci with an inverted segment and noninverted lateral discoid menisci was performed by use of Fisher exact test and Mann-Whitney test. RESULTS Nineteen patients with an inverted discoid meniscus segment (14 males, 5 females; average age, 15.0 years; range, 9.5-17.0 years) were compared with 102 patients with a noninverted discoid meniscus (53 males, 49 females; average age, 12.3 years; range, 5-17.0 years) (P = .011 for sex and P < .001 for age). All 19 discoid meniscus patients with an inverted segment had activity-related knee pain. Only 4 patients (21.0%) reported mechanical symptoms. Patients with an inverted discoid segment, compared with patients with discoid menisci without inverted segments, were more likely to have instability and effusion (P = .012 and P < .001, respectively). Eighteen discoid meniscus patients with an inverted segment (94.7%) had an injury, while only 41.2% of patients with noninverted symptomatic discoid menisci had an injury (P < .001). On MRI, an inverted discoid segment was seen as a horizontal longitudinal tear, a free fragment, or a double meniscus. During arthroscopy, the inverted discoid segment appeared normal, without a tear; upon probing, however, the inverted segment could be exposed. CONCLUSION An inverted discoid segment occurs during adolescence, and it is more likely to occur in male patients and more likely to be associated with activity-related pain and injury compared with a noninverted symptomatic discoid meniscus. A discoid meniscus with an inverted segment does not have the standard radiographic and arthroscopic features normally associated with a discoid meniscus.
