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.

Circumferential Fiber Augmentation Technique Combined With Transtibial Pullout Repair.

This Technical Note describes a surgical approach that combines circumferential fiber augmentation with transtibial pullout repair for the treatment of medial meniscal posterior root tears. To address the challenge of meniscal extrusion and subsequent joint space narrowing that predisposes to osteoarthritis, this technique uses an artificial ligament to add circumferential collagen fiber reinforcement to improve meniscal extrusion. This integrated approach is designed to address the limitations of conventional tibial pullout repairs by potentially providing better results in preventing meniscal extrusion.

Inside-out repair of meniscal tears is the gold standard surgical approach; however, its use is limited by the need for a posterior incision and neurovascular risk. In this Technical Report, we present details of the all-inside arthroscopic tie-grip approach for repairing a radial tear of the midbody of the lateral meniscus using an all-inside device (TRUESPAN) and a slotted cannula. In contrast to the inside-out approach, this technique helps reduce surgical invasiveness and provides stable fixation as the vertical mattress sutures bundle the circumferential fibers and act as rip stops for the horizontal sutures.

Background: Meniscus tears can change the biomechanical environment of the knee joint and might accelerate the development of osteoarthritis. The aim of this study was to investigate the dynamic biomechanical effects of different medial meniscus tear positions and tear gaps on the knee during walking.
Methods: Seven finite element models of the knee joint were constructed, including the intact medial meniscus (IMM), radial stable tears in the anterior, middle, and posterior one-third regions of the medial meniscus (RSTA, RSTM, RSTP), and the corresponding unstable tears (RUTA, RUTM, RUTP).

Cranial cruciate ligament (CCL) disease causes variable stifle instability assessed by specific clinical tests. Radiographs are performed to measure the tibial plateau angle (TPA) for planning tibial plateau leveling osteotomy (TPLO) surgery. Concomitant damage to other intra-articular structures, for which clinical detection is unreliable, may occur and potentially affect the surgical outcome.

Introduction: Acute anterior cruciate ligament (ACL) injuries can be disabling because of prolonged rehabilitation process following surgical reconstructions. Rates of ACL injuries among military service members are close to 10 times greater than the general civilian population, likely because of the operation tempo and the unique physical requirements. Studies debated functional testing requirements for return to sports, but no study investigated the impact of functional training and re-injury rates following ACL reconstruction and their association with functional testing outcomes and time to return to full duty in United States Naval Academy (USNA) Midshipmen.
