“…The primary finding in this study was that the overall incidence of concomitant meniscal tears in MLKI was 15.3% for the medial meniscus and 17.9% for the lateral meniscus, and was therefore less common than in isolated ACL injury [6, 12, 21, 22]. A consistent relationship was observed between Schenck classification, side of collateral ligament injury and the rate of meniscal damage.…”

PurposeMeniscal injuries occurring during multi‐ligament knee injuries (MLKI) are underreported. The purpose of this study was to compare the incidence and type of meniscal tears seen at the time of multi‐ligament reconstruction surgery compared to those occurring during isolated anterior cruciate ligament (ACL) surgery. MethodsPatients undergoing surgical treatment for MLKI and ACL‐only injuries between 2010 and 2020 were reviewed. Two‐hundred and thirty‐five patients were included in the MLKI group. There were 131 chronic injuries and 104 acute injuries. Two‐hundred and twenty‐two ACL‐only chronic injuries were used as a control group for comparison with the chronic MLKI group. Demographic data, type of meniscal tears, ligament injury patterns (Schenck classification) and time from injury to surgery were recorded. A delayed procedure was defined by a 4‐week interval after the knee injury. ResultsA meniscus was torn in 69 knees (29.4%): 36 knees (15.3%) with an isolated medial meniscus tear, 33 knees (17.9%) with an isolated lateral meniscus tear,.Nine knees (3.8%) had both menisci torn. MLKI with medial or lateral‐sided bicruciate ligament injuries (KDIIIM‐KDIIIL) were significantly associated with a lower rate of meniscal tears than knee injuries involving the ACL‐only and medial/lateral‐sided ligament injuries (KDI) (medial‐sided injuries p = 0.025; lateral‐sided injuries p = 0.049). Lateral‐sided injuries had significantly less meniscal damage than medial‐sided injuries: 22/124 (17.7%) vs. 41/100 (41%); (p < 0.001). No significant differences were found for frequency, type and distribution of meniscal tears between acute and chronic MLKI surgery. ACL‐only chronic injuries were associated with a higher rate of meniscal tears: 123/222 knees (55.4%) vs. 35/131 (26.9%) chronic MLKI; (p < 0.001), mainly involving the medial meniscus: 102/222 (46%) vs. 18/131 (13.7%); (p < 0.001). ConclusionsMeniscal tears were less common in the MLKI group than in the isolated ACL injury group. The degree of ligament injury patterns and the side of the injured collateral ligament influenced the type and incidence of meniscal damage. Contrary to isolated ACL injuries, a delayed procedure was not associated with a higher rate of meniscal lesions but did influence the type of treatment. Understanding of meniscal tears patterns in MLKI helps to improve the treatment management of these complex injuries.

“…Seyma Torgutalp S et al [14] have a different opinion; they suggested no significant differences between partial and complete tear groups regarding incidence rates of injuries accompanying the ACL tear. At the same time, Gupta R et al [15] indicated that partial ACL injuries present less risk of acquiring isolated meniscus tears than complete ACL injuries.…”

Objective: To assess the incidence of the associated meniscal ligament (ML) with the anterior cruciate ligament (ACL) tears in hospital A in Medina-KSA. And to see the effect of sports activities in comparison between males and females. Materials and Methods: In a retrospective study, ninety-nine patients' knee magnetic resonance imaging (MRI) records were selected conveniently from the (A) hospital's picture archiving and communication system (PACS). Patients with suspected anterior cruciate and meniscal ligament' tears were included. Patients with posterior cruciate ligament (PCL) tear, medial collateral ligament (MCL) or lateral collateral ligament (LCL) injury, and previously operated index knees were excluded. All patients were scanned by a 1.5T MRI machine using standard MRI knee scanning protocol. The categorical and continuous variables were presented as percentages, frequencies, and descriptive statistics. The cross-tabulations and chi-square test were applied to obtain the statistical associations between the study variables. A statistical association was considered significant if the P-value was < 0.05. Results: 72 males and 27 females were included, with a mean age of 33 ± 2.43. 42.4% of the knee tears were ML tears, followed by associated (ACL with ML) tears, noted in 31.3%, and 26.3% were ACL tears. The tears were more frequent in the age group (31-40), reported in 35.3% (out of 99). There was no statistical association between the tears and the participants' age, gender, or sports activities; P value = 0.3, 0.5, and 0.9, respectively. Conclusion: The study concluded that the isolated ML tears were more frequent than the associated (ACL with ML) tears—moreover, there was no significant statistical association between the participants' age, gender, or sports activities.

“…In addition, there was a significantly higher rate of complete ACL tears in the LMPRT group than in the control group. Generally, complete ACL tears were more frequently complicated by meniscus tears, especially those in the posterior horn [17]. Although a causal relationship between complete ACL tears and LMPRTs could not be determined in the present study, it was hypothesised that morphological factors, such as lateral–medial asymmetry of PTS and small LTP AS depth, would predispose to a more intense rotational shift at the time of injury, resulting in a greater proportion of damaged ACL fibres, greater occurrence of LMPRT and MM ramp lesions, and ultimately a higher grade of pivot shift.…”

Purpose To investigate whether knee morphological features, patient characteristics, and intraoperative indings are associated with a lateral meniscus (LM) posterior root tear (LMPRT) in anterior cruciate ligament (ACL) injuries with the integrated data from two academic centres. Methods This retrospective study used registry data acquired prospectively at two academic centres. Patients with ACL reconstruction (ACLR) with LMPRT and no other LM injury were selected (LMPRT group) from each database. The control group included patients who underwent ACLR without LM tears. Patients were matched to the LMPRT group according to age and gender (1:1). Morphological factors evaluated on preoperative magnetic resonance image scans included lateral femoral condyle (LFC) anterior-posterior diameter, height, and depth; lateral tibial plateau (LTP) articular surface (AS) depth and sagittal plane depth; and lateral and medial posterior tibial slopes (PTSs). LFC height and depth ratios, LTP AS depth and sagittal plane depth ratios, and lateral-to-medial slope asymmetry were computed from previous measurements. Patient characteristics and intraoperative indings were extracted and compared between both groups. ResultsThe study included 252 patients (126 in each group). The lateral-medial asymmetry of PTS was greater in the LMPRT group (1.2° vs 0.3°, p < 0.05), and the LTP AS depth was smaller in the LMPRT group (31.4 mm vs 33.2 mm, p < 0.01). There were no diferences in LFC morphology between the control and LMPRT groups. Pivot shift grade (p < 0.05), percentage of complete ACL tears (p < 0.05), and medial meniscus ramp lesions (p < 0.05) were signiicantly higher in the LMPRT group. Conclusion LMPRT was associated with signiicantly increased lateral-medial asymmetry of PTS and signiicantly smaller LTP AS depth. LMPRT was also associated with an increase in the preoperative pivot shift grade and the presence of a medial meniscus ramp lesion. These morphological characteristics are rather simple to measure and would serve as helpful indicators to preoperatively detect LMPRT, which is frequently challenging to diagnose preoperatively. Level of evidence Level III. KeywordsLateral meniscus posterior root tear • ACL injury • Posterior tibial slope • Lateral tibial plateau articular surface depth * Hideyuki Koga
