During the exam, your doctor will look for signs of tenderness along the joint line. It has been reported that the force experienced by the medial meniscus in the ACL-deficient knee increased by 52% in full extension and by 197% at 60 of flexion under a 134-N load. Adjunctive measures to promote vascularity and healing at the repair sites are also recommended. Jarit G, Bosco J. Meniscal repair and reconstruction. Liodakis E, Hankemeier S, Jagodzinski M, Meller R, Krettek C, Brand J. Cole BJ, Dennis MG, Lee SJ, et al.

The treatment may be conservative or sometimes surgery may be required to treat the fracture. Surgery is typically the only option and works to trim the damaged portion of the meniscus. The lateral meniscus is on the outside of the knee. The medial meniscus transmits approximately 50% of the total joint load of the knee medial compartment, thus protecting the articular cartilage from excessive force. 8 Ruff C, Weingardt J, Russ P, Kilcoyne R.

Biomechanical studies have demonstrated that repair of medial meniscus posterior root tears leads to improved contact mechanics. If mechanical symptoms are present in this subset of patients, a partial or subtotal meniscectomy may improve symptoms; although, these tears are not usually associated with traditional meniscal-based mechanical symptoms. See your ortho for an evaluation. A meniscectomy requires less time for healing approximately 3 to 6 weeks.

Flaps cause mechanical instability - meaning they interrupt the smooth function of the knee joint and will make your knee joint feel unstable. Afterward, you may experience: pain, especially when the area is touched. The degenerative aetiology and reduced vascularisation secondary to ageing also means that meniscal tears in the elderly population are less likely to be amenable to surgical management;7 only about 6% of patients over 40 years of age have operable lesions.24 To prevent re-injury of the meniscus, activity modification is important for example, ceasing sports such as soccer or netball. Collateral and cruciate ligaments are intact. Symptomatic treatment with rest, ice, NSAIDs and/or an unloader brace may help alleviate symptoms in some cases.

The medial meniscus is on the innermost side of your knee (the C-shaped curve faces in toward your body, the opposite knee). Crawford R, Walley G, Bridgman S, Maffulli N. Magnetic resonance imaging versus arthroscopy in the diagnosis of knee pathology, concentrating on meniscal lesions and ACL tears: a systematic review. Repair of locked bucket-handle meniscal tears in knees with chronic anterior cruciate ligament deficiency. Because a torn meniscus is made of cartilage, it won't show up on X-rays. Sounds like it will not get better without arthroscopic surgery. As the risk of osteoarthritis is increased if meniscal structures are not optimally functional,7 it may also be appropriate to refer all young patients for opinion if symptoms do not rapidly improve.

The meniscus is a C-shaped cartilage disk that is found in the knee. If the test is positive (suggesting a meniscal tear), the patient will feel pain and the clinician will feel and/or hear meniscal movement when the meniscus is compressed between the tibia and femur 32, Figure 2. However, coronal sections may reveal the presence of meniscal extrusion or vertical defects, and sagittal sections may reveal the ghost sign (absence of an identifiable meniscus or increased signal replacing the normal hypointense signal of meniscal tissue). what is the treatment?

This type of tear has an unusual pattern. What is Meniscus Radial Tear. See your ortho for an evaluation. This is termed the 'red-red zone' (denoting area of vascularity).2,4 repair of the 'red-white zone' (watershed area between vascular and avascular meniscus) is controversial25 with many different surgical techniques.26 tears in the 'white-white zone' (avascular zone) are rarely repaired rather the damaged segment is resected (meniscectomy). The double posterior cruciate ligament (PCL) sign appears on sagittal MRI images of the knee when a bucket-handle meniscal tear (medial meniscus in 80% of cases) flips towards the center of the joint so that it comes to lie anteroinferior to the posterior cruciate ligament (PCL) mimicking a second smaller ligament..
