Patients with ACL tears are also thought to be better candidates for meniscal repair because of the presence of serum-derived growth factors within the hemarthrosis that accompanies ACL tears.15. Arthroscopy. Knees with a deficient medial meniscus and an ACL tear have an increased anterior tibial translation of about 60% at 90 of flexion. Grade 3 is a true meniscus tear and an arthroscope is close to 100 percent accurate in diagnosing this tear. Radiology 2000; 217:193-200. 1 Sutton JB.

Bucket-handle tears are actually a form of longitudinal tear in which subsequent displacement of the inner rim of the tear results in a configuration that resembles the handle of a bucket (11a).

For potential or actual medical emergencies, immediately call 911 or your local emergency service. With the realization that even partial meniscectomy leads to accelerated osteoarthritis,2 surgeons have increasingly turned to meniscal repair. This "C" shaped cartilage helps disperse impact and displace force exerted upon the knee while walking, running, and other mild to high-energy and impact motions. Transtibial pullout repair is a new arthroscopic technique to repair meniscal root tears, . Knee Surg Sports Traumatol Arthrosc 2010;18:5359. Orthop Clin North Am. Herrlin S, Hallander M, Wange P, Weidenhielm L, Werner S. Arthroscopic or conservative treatment of degenerative medial meniscal tears: a prospective randomised trial.

Because the pieces cannot grow back together, symptomatic tears in this zone that do not respond to conservative treatment are usually trimmed surgically. 2. Clin Sports Med 2010;29:81106. Biomechanical studies have demonstrated that repair of medial meniscus posterior root tears leads to improved contact mechanics. The goal of meniscal root repair is to restore the joint to a near native function of the meniscus and prevent cartilage degradation associated with nonsurgical treatment or meniscectomy. If the fracture is stable or closed where the bones do not move out of alignment then simple immobilization with the use of a sling, splint or cast for a few weeks allowing the fracture to heal may be enough. We describe the technique of diagnosis and treatment of a large displaced lateral meniscus flap tear, presenting as a meniscus comma sign. Meniscal tears may be categorized into five common configurations, including horizontal, longitudinal, radial, oblique (parrot-beak), and complex. Still, many people with a torn meniscus can walk, stand, sit, and sleep without pain. These tears often require surgical treatment to restore the proper function of the knee.

Case Discussion Longitudinal tears, also known as vertical tears, occur perpendicular to the tibial plateau and parallel to the long axis of the meniscus splitting the meniscus into inner and outer parts. (Right) Degenerative tear. Flaps cause mechanical instability - meaning they interrupt the smooth function of the knee joint and will make your knee joint feel unstable. Meniscal repair surgeries do the best when the meniscal tear extends into the middle 50% of meniscal substance. To learn more, please visit our. The amount of pain and first appearance of swelling can give important clues about where and how bad the injury is. Studies have also reported that patients who underwent a repair of the posterior root in the medial meniscus slowed the progression of arthritic changes compared with those who had a meniscectomy; although, this did not completely prevent the arthritic changes. Injury, degeneration, or surgical removal of all or part of the meniscus is associated with an increased risk of developing knee osteoarthritis. AJR 2003; 180:93-97.

This pattern of tear requires resection to prevent propagation of the tear as the flap gets caught within the joint during flexion. The posterior horn is located on the back half of the meniscus. Both longitudinal and radial tears may appear vertical on MR images (5a,6a), but longitudinal tears extend parallel to the c-shaped circumference of the meniscus, whereas radial tears lie perpendicular to the meniscal circumference. In cases where a torn meniscus has locked the knee, walking will be affected. Peripheral meniscal tears are located in the most vascular portion of the menisci and comprise 39-72 % [2, 3, 56, 69, 82] of all meniscal tears. what is the best possible treatment?

Without nutrients from blood, tears in this "white" zone with limited blood flow cannot heal. Although the . Nonoperative treatments are often successful in patients with certain types of tear patients who have no loss of joint function, suffer minimal pain or swelling and are willing to reduce their activities temporarily or in the long term. 8 Ruff C, Weingardt J, Russ P, Kilcoyne R. MR imaging patterns of displaced meniscus injuries of the knee.

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. Meniscal pain occurs during torsional, weight bearing knee movements (classically pivoting on the knee while walking) as a sharp stab lasting several seconds, often followed by a dull ache for several hours.

The medial meniscus is the portion of the cartilage along the inside of the knee joint (closest to the other knee). Tears are noted by how they look, as well as where the tear occurs in the meniscus. A tear can also develop slowly as the meniscus loses resiliency.

Most commonly it is impossible to fully extend the knee; more accurately described as stiffness (termed 'pseudo locking') due either to a small effusion (requiring increased force to bend the tense joint capsule) or to pain inhibition as the femoral condyle compresses the torn meniscus. AJSM 2003; 31:216-220. These tears occur within the avascular zone of the meniscus where there is no blood supply. A tear of the anterior horn of the lateral meniscus is damage to the front part of one of the two structures that act as shock absorbers between the thigh bone and the lower leg, explains The Steadman Clinic.
