“…There are many reports on the importance of the medial meniscus for limiting anterior translation in anterior cruciate ligamentdeficient knees, whereas the lateral meniscus does not perform this function [21][22][23][24][25]. However, an isolated medial or lateral meniscectomy in knees with an intact anterior cruciate ligament does result in increased anterior tibial translation [23]. Meniscal tears typically occur during sudden turns and loadings, with various flexion and extension angles [14,16].…”

Objective: The geometry of the tibial plateau has a direct influence on the translation and the screw home biomechanics of the tibiofemoral joint. Little information on the relationship between the tibial slope and meniscal lesions is available. The objective of this retrospective study was to examine the effect of the tibial slope on the medial and lateral meniscus lesions in patients with intact ACLs. Materials and Methods:The MRIs and lat roentgenograms of 212 patients with meniscus lesions were examined to determine the possible effect of the tibial slope on meniscal tears. First, the anatomic axis of the proximal tibia was established. Then, the angle between the line drawn to show the tibial slopes (medial and lateral) and the line drawn perpendicular to the proximal tibial anatomic axis was established on MRI. The patients with previously detected meniscus lesions were classified into three categories: patients with only medial meniscal tear (Group 1, 90 patients); patients with only lateral meniscal tear (Group 2, 15 patients); and patients with both medial and lateral meniscal tear (Group 3, 19 patients). Group 4 had no meniscal tear (88 patients). The MRIs of the patients who had applied to the Orthopedic Outpatient Clinic with patellofemoral pain and no meniscal tear were included as the control group.

“…The meniscus has also been suggested to assist in joint stability, lubrication, and proprioception (Markolf et al 1981, Levy et al 1982, Shoemaker and Markolf 1986, Zimny et al 1988, Levy et al 1989, Assimakopoulos et al 1992). …”

Meniscal tear - a feature of osteoarthritis

Meniscectomy is recognized as an important risk factor for the development of knee osteoarthritis (OA), a disease that traditionally has been considered as a simple "wear and tear" phenomenon. However, despite numerous reports, little evidence has been presented that a limited meniscal resection, compared with a more extensive resection, reduces the risk of OA by preserving meniscal function. Why? This thesis provides one possible answer to that question.Patients, who had undergone isolated meniscal resection in 1973, 1978, or between 1983 and 1985 at Lund University Hospital, Sweden, were reviewed clinically and radiographically 15-22 years after the surgical procedure.Of the subjects (n = 317) almost 50% had developed radiographic OA in their operated knee, but just over half of these patients were symptomatic. An additional 20% of the patients had knee symptoms, but did not have radiographic knee OA. These results confi rm a limited correlation between radiographic features of the disorder and symptoms.A degenerative type of meniscal tear and obesity were the factors most strongly associated with both radiographic knee OA and symptomatic radiographic knee OA.Partial meniscal resection induced less radiographic changes related to knee OA compared with total meniscectomy, but the patient-relevant outcomes remained essentially the same.If radiographic hand OA was present there was an increased likelihood of the patient also having knee OA following meniscectomy. This fi nding was independent of age, and therefore an inherited susceptibility to the disease contributes to the risk of knee OA after meniscal tear. Genetic and environmental risk factors interact in OA development.A degenerative meniscal lesion is often associated with early-stage knee OA, a disorder also involving the meniscal tissue. The tear may thus represent the fi rst "signal" feature of OA. The challenge for the health professional is to discriminate between symptoms caused by a meniscal tear and those caused by OA. Meniscal resection may not benefi t the patient with early-stage knee OA. The intervention merely removes evidence of the disorder, while the OA joint degradation proceeds.

“…Analogous to the PTS, the MS is the angle between a tangent line between the superior meniscosynovial border of the respective meniscus and the LA [25]. The posterior meniscal horn is thicker than the anterior meniscal horn; therefore, the effect of the bony PTS could decrease with a lesser MS or, vice versa, increase with a greater MS [25,28,29]. We suppose that a greater MS reduces AP knee stability analogous to a resection or injury of the posterior meniscus.…”

Background The risk of noncontact ACL injury reportedly is increased in patients with a greater posterior tibial slope (PTS), but clinical data are inconsistent. It is unclear whether the medial and lateral PTSs have a different impact on this connection. It also is unknown whether the meniscal slope (MS) is associated with ACL injury. Patients/methods Using MRI, we compared the medial and lateral PTSs and MSs separately in 55 matched pairs of patients with isolated noncontact ACL injuries and a control group.
