“…Final findings about discrepancy of the femur on the tibia are close but not strictly comparable to the work of Wahl et al [17] and Bozkurt et al [18] that suggested an association between meniscus tears and femorotibial compartment congruency in patients with acute ACL ruptures, defined by a less concave medial tibial plateau articulating with a more convex medial femoral condyle.…”

“…There is, however, an abundance of research investigating anatomic risk factors for isolated ACL rupture (excessive tibial slope [10–12], intercondylar notch width [13, 14], lateral morphology of the knee [15–17]). Limited prior work evaluating risk factors associated with meniscus pathology has suggests decreased femorotibial congruency, excessive tibial rotation, and a discrepancy between femoral condyle and the tibial plateau lengths may play a role [18–20].…”

Anatomic risk factor for meniscal lesion in association with ACL rupture

Background To assess anatomic risk factors for meniscal lesions in association with acute ACL rupture. The primary hypothesis was that tibiofemoral anatomic measures will be different in those with and without concomitant meniscus tears. Methods A retrospective review of patients who underwent acute ACL reconstruction in the department was performed. All patients underwent a postoperative CT scan. The concavity and/or convexity on the femur and the tibia were measured by two blinded observers on the sagittal plane with different ratios, and these measures were compared in patients with and without meniscus tears in each compartment. Intra- and inter-rater reliabilities were assessed. Results Four hundred twelve patients (268 males and 144 females) were included from October 2012 to February 2015. One hundred sixty-seven patients had a medial meniscal tear (119 males/48 females), and 100 had a lateral meniscal tear (80 males/20 females). The mean time from injury to surgery was 3 months. The average ICC for all measurements was 0.87 (range 0.82–0.98) indicating good reliability. The medial femoral condyle was noted to be significantly longer than the medial tibial plateau in the sagittal plane in patients with a medial meniscal tear ( p = 0.04), and the lateral femoral condyle was noted to be significantly longer than the lateral tibial plateau in the sagittal plane in patients with a lateral meniscal tear ( p < 0.001). In addition, a less convex lateral tibial plateau was statistically correlated with a higher risk of lateral meniscal tear ( p = 0.001). Conclusions A greater anteroposterior length of the medial/lateral femoral condyle relative to the medial/lateral tibial plateau is associated with an increased risk of meniscal lesions in association with acute ACL rupture. The lateral compartment in the male population appears to be the most at risk. Trial registration Retrospectively registered on May 12, 2016 (CPP sud-est II CAL n°2016-037)

“…Several parameters are related to the width of the femoral notch (11,12), such as the notch width (NW), bicondylar notch width (BCW), the notch width index (NWI), condyle width of the femur, tibial spine height, and intercondylar angle. However, limited prior studies evaluated the anatomical risk factors for the injury of meniscus (21)(22)(23)(24).…”

Background To assess the geometrical risk factors for meniscal injuries. Our hypothesis was that the narrowness of the intercondylar notch and the smaller tibial spine could increase the risk of meniscal injuries. Methods We retrospectively studied two hundred and seven patients examined for knee magnetic resonance images. The severity of meniscal injuries was evaluated by two experienced orthopedists. The notch width, bicondylar notch width, notch width index, condyle width of the femur, tibial spine height, and intercondylar angle were measured in magnetic resonance image slides by two blinded orthopedists. Results In all two hundred and seven patients, 112 patients with a meniscus injury and 95 patients were as healthy control. The NWI (P = 0.027) in patients with meniscus injuries was significantly different from the control group. A 1 SD (0.04 mm) increase in NWI was associated with a 0.4-fold increase in the risk of meniscal injury. A 1 SD (0.04 mm) increase in NWI was associated with a 0.64-fold increase in the risk of grade 3 meniscal injury. Furthermore, NWI and medial spine height are decreased significantly in grade 2 (P < 0.05) meniscal injury than in other grades. The medial spine height was significantly decreased in the meniscal injury group (P = 0.025), and the decrease of medial spine height would increase the risk of meniscal injury (OR = 0.77) and grade 3 meniscal injury (OR = 0.8). Conclusions The stenosis of the femoral intercondylar notch and small medial tibial spine are risk factors of meniscal injury. The decreased NWI and the decreased medial tibial spine height were also associated with the severity of the meniscal injury.

[2][3][4] Studies have shown the medial meniscus is affected more than the lateral due to differences in meniscal anatomy and articular geometry. 5,6 An ACL deficiency causes four times the typical amount of anterior tibial translation (ATT) and consequently places additional demands on the medial meniscus to act as the knee's primary stabilizer in the anterior-posterior, internalexternal and varus-valgus directions.…”

Two unloader knee braces effectively reduced strain in the medial meniscus with an intact anterior cruciate ligament during dynamic activities. Neither brace made a significant reduction in strain for anterior cruciate ligament-deficient knees. Clinical relevance Unloader knee braces could be used to reduce the medial meniscus strain following meniscal surgery and during rehabilitation in patients with an isolated medial meniscus injury. However, these braces cannot be recommended for this purpose in patients with an anterior cruciate ligament deficiency.
